Stylish - Custom themes for any website

Rated 3 out of 5 stars

The complaint is not really about Stylish, it is about Firefox, but Stylish is no good to me beyond FF 56.0.2 because all of the styles I use are not themes, and only themes can be done in Stylish now because Firefox is crap beginning with FF 57. If Firefox is going to look like Chrome, act like Chrome, use Chrome as a goal-- you might as well not be using Firefox.

I have put Stylish back to pre version 3.0, and Firefox, extensions including Stylish styles are no longer allowed to update themselves. I guess in 3 months I will switch to Chrome I've had to use it all too many times up to now. Stylish and extension were what kept Firefox usable and enjoyable (FF not so enjoyable starting around 3.0 when they started to lose sight of their users).

I wish I could tell you to look at the styles I wrote and the others I also use but the pictures are incomplete not showing before and after and are distorted and cropped.

* As I understand it Firefox 57 will not allow or will only allow for a while changes to Firefox structure interface, no more changes to toolbars, scrollers, scroll thumbs to make them visible, unhiding hidden or self hiding scroll bars, eliminating wasted space on toolbars making them more readable in 1/4 the space. Almost every extension that I have left is marked legacy and has to do with toolbars. Loss of bookmark functionality. The only extensions that will remain appear to be Adblock Plus and Stylish themes.

* More on the Firefox 57 Fiasco -- https://blog.mozilla.org/addons/2017/02/16/the-road-to-firefox-57-compatibility-milestones/

* If Firefox is is just going to remove features not available in other browsers and play catch-up to Chrome, as if that is desirable, then why continue to use Firefox at all. Dumbing down Firefox to Google Chrome's level is going to eliminate the remaining Firefox users who have persevered through all of Mozilla's shenanigans.

* If you try to read up about an extension now they've f*ck*d that up as well. Most important items: version, size, releases it works with, stars, description, developer's comments, user comments & developer comments related to a user comment.

Works Fine in Firefox 55 from developer channel Rated 5 out of 5 stars

This is not the place to report problems, but you can obtain the latest Developer version at the bottom of this page it is Version 2017.03.19.12b the B is beta if you install it your updates remain in Developer Channel until you reinstall. Since everybody appears to be getting FF 55.0.2 expect latest version of this addon in 2-3 days. You may have to go into Customize toolbars and drag "Status Text" to the status bar. (Those that gave a bad rating might consider revising their comment and rating later)

Highlight Tabs

Keyboard shortcuts are same as used in Multiple Tab Handler Rated 3 out of 5 stars

Would prefer to comment without rating but not an option. Warning is for potential users of MTH which provides customized formatting of Titles, Description, URL, etc into the clipboard of multiple tabs. The "Tab Colors" and "Highlight Tab" extensions use the tab context menu, avoiding keyboard shortcut conflicts and give choice of colors when invoked.

History in Threads

Works well, as an additional history sidebar list, not intending use as a replacement. Rated 5 out of 5 stars

Does what it is supposed to do.

(39.2KB), installed but not shown in addons until Firefox was restarted. Some of usage directions are on images. Invoked by clock toolbar button (History), modified history list appears in side panel, suggest display column last visited (next to name), then do a search invoked with Enter key (not magnifying glass), if link was called from or calls a link those clusters will be shown. Open entry in new tab with right-click (context menu), or middle-click, if available.

Copy Tabs

Not there yet, not repeatable Rated 2 out of 5 stars

Invoked from menu (=). Worked one time, but that sucess was not repeatable. So it does not appear to do what it is intended to do.

Won't hold format against it, but any time I make up a similar list as text from "Multiple Tab Handler" where I have complete control over format, I would put title first, then url, given only those two items.

Multiple Tab Handler

Rated 5 out of 5 stars

Firefox 33.0.2 did not auto update extension to 0.8.2014102201. Update MTH and "Close all tabs" and Ctrl+click to extend tab selection will work again. See version notes.

Multiple Tab Handler

MTH does exactly what is says it does and more. But don't expect it to fix other extensions. Rated 5 out of 5 stars

MTH works exactly as documented, it even has customizable copyurl features (Title, URL, description, meta data) which are equally useful and compatible with tab selection.

There is a comment where the reviewer expects the author to do something based on the comment. Notes to reviewers specifically state to use the contact information (author would not understand the question in English and especially when the comment is related to problems strictly concerning other extensions). The author went so far as to write an API that other developers could integrate multiple tab selections into their extensions -- it is not part of Firefox. "Menu Editor" makes use of the API.

TMP - steps all over the configuration options of Firefox. One should avoid using it, it is large and unwieldy.

TGM - didn't like the waste of space, but Firefox has since added app tabs, and tab groups. You might want to try Tab Groups Helper which does integrate or at least recognize current features of Firefox such as app tabs and tab grouping and improve things along those lines (side by side groups). TGM is not of interest to me personally.

Sort Tabs

Rated 5 out of 5 stars

Does what it says it does. Been wanting something along these lines for a long time. Would be much improved if it tied into the API selection of "Multiple Tab Handler". MTH is great for documentation of tabs as text, html, wiki or other text formats and "Sort Tabs" will help when alphabetical order of included tabs is desired.

Copy URL

Rated 4 out of 5 stars

There already are Firefox keyboard shortcuts to do this. Ctrl+L followed by Ctrl+C, then no need for extension. Adding keyboard shortcuts to extensions as one person requested are almost certainly going to conflict with other extensions or with Firefox itself. Such issues can be resolved but it is best to avoid them.

After the Deadline - Spell and Grammar Checker

Works smothly, roughest part was adding to dictionary Rated 5 out of 5 stars

Great extension. Never had a grammar checker in Firefox before and it works very well. The only problem was clicking on 450 words to add into the dictionary -- this one uses cookies, and not persdict.dat in the Firefox profile. I moved "ignore always" to the top of the context menu with the "Menu Editor" extension click on marked word with mouse in right hand, click on "Home" then "Enter" with left hand. I sure am glad everyone uses real dictionaries now when I did this 25 years ago I had to type or paste over 7000 words to our main dictionary and compile it.

Close Tab by Double Click

Won't close last tab nor app-tab Rated 4 out of 5 stars

Incorrect and frustrating in not closing the last tab with user set "browser.tabs.closeWindowWithLastTab" to false, that option if true is supposed to close Window not just the tab. But set to true should be able to close the tab and not window. AND now (1.14) won't close an app-tab. Use Ctrl+W or tab context menu to close the last tab or an app-tab (or install much larger tab "clicking options"). Can't use with either of these two non-Firefox usages. So forced to use Tab Clicking Options just to close a tab with a double-click. [edited: now using "Double Click Closes Tab" which does what I want]

Tab Counter

Additional Formatting can be made Rated 5 out of 5 stars

In Firefox 4.0, the tab counter can be moved to the Tabs Bar in addition to anywhere in Menu Bar, or Location Bar in Firefox 3.6. This means one can make the tabs bar always visible even in full screen ("F11") and include the tabs count. The following styling includes color and different padding in the code to make the tab count really stand out which could be included via userChrome.css provide additional styling not available in the extension's options, but it is more convenient to use the "Stylish" extension, and is include in "Tabs Bar Minimal Size" -- http://userstyles.org/styles/9043/tabs-bar-minimal-size

/* "Tab Counter" Extension can be moved to the tab bar in Fx4.0 */
#tabcounter-toolbar-item {font-size:12px; font-weight:700 !important;
margin:0px !important; padding:0px 2px 0px 2px !important;background-color: yellow !important;
border:1px solid black !important;}

Rated 5 out of 5 stars

Thanks for the update 0.10.4 available at your site http://mozilla.doslash.org/infolister/ works great alone or with template. Tested in 4.0b11 and in 4.0b12pre Review mainly for those that don't look at developer's notes, or may not notice developer's reply which can only be seen on "See all reviews". Thanks Nickolay for updating.

Status text working perfectly Rated 5 out of 5 stars

Thanks for the extension, I don't know what Mozilla is doing making things not upward compatible. I spend so much time fixing such unnecessary incompatibilities. The "Status text" is perfect fix the one removed from Firefox. The extension's "Progress meter" doesn't work in 4.0b7pre on Windows 7, but the Firefox built-in progress meter works as well as any of their GUI "improvements". Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0b7pre) Gecko/20100930 Firefox/4.0b7pre

To Display what had been the status bar in Firefox 4.0b7pre
View --> Toolbars (Alt+V+T) --> (check) Addons Bar

Excellent, but buttons need to toggle Rated 5 out of 5 stars

Learned about this extension after reading about "Reader" in Safari (5.0) which added a simple toggle switch to the address bar, though it takes too much space there a simple "R" would have sufficed. The button changes color when it toggles the view (good).

"Readability" extension in Firefox has an "R" on the status bar click to invoke, right-click to change formatting styles / margins. Unfortunately buttons do not toggle. To return to normal view use the Refresh looking button added to leftside of the webpage. I changed addons options Ctrl+Alt+R to Ctrl+Alt+S (summary) because the default conflicted with "QuickRestart" extension, I also deactivated autoscroll shortcut (probably useful for others) with "keyconfig" extension. Keyboard shortcut has no advantage because it does not toggle either. Optional toolbar button is same as on status bar but takes additional space for unneeded drop-down arrow when right-click would do just fine.

Adds a Highlight Summary at top from phrases within article. Built-in Safari "Reader" lacks both a Summary and formatting options.

If the buttons were removed from the left, it could have minimal margins more suitable for portable devices and netbooks. Addition of the print and email to right click on button would make that possible.

Read Easily

incompatibility nonsense Rated 5 out of 5 stars

Turn off compatibility tests and reinstall from the "View Older Versions" link.

This extension works fine in all versions of Firefox, both with the toolbar button and with the keyboard shortcut (Ctrl+Shift+Z). Shame people think they have to find a substitute. Perhaps the "Add-on Compatibility Reporter" reporting in Firefox Betas will restore some sanity to the ongoing lunacy about incompatible extensions. Meanwhile see http://www.mvps.org/dmcritchie/firefox/infolister_listing.htm#compatibilitydisabled

Open Profile Folder

Rated 5 out of 5 stars

Nice to know that the option to open in an application of choice was added in version 1.3, though I will still be using system default. Firefox 3.6 will introduce Help -> Troubleshooting Information to identify profile, which will work in Safe Mode, but nothing beats using this small extension to actually get to your profile.

Stylish - Custom themes for any website

Managing has just become difficult Rated 5 out of 5 stars

The bloated presentation format has made it difficult to manage the styles. Amazingly the extension is now smaller, but these are the problems.
1) can no longer sort on choice of 'checkmark', 'description', 'applies to' via column headings. Forget to see if there are options, but I need to be able to change immediately where used, and be able to sort on my own modified description names. Some for instance are prefixed with "(bad)" or "(off)" as I often turn on or off a lot of them at one time and those I keep turned off,
and know which of the other to normally have on or off.
2) bloated line height in manager by addition of ugly icon.
3) ugly icon added to menu bar is really messed up does not conform to proper size.

Gone back to 0.5.9 which is still working had no complaints about it and organization works out a lot better. On the other hand 1.0 has Bold for active, and Gray for inactive and mystery sorting.

Bookmark Duplicate Detector

Serious problem for SortPlaces Rated 4 out of 5 stars

Will have to disable this extension, it had been okay in 3.0.7 when adding a bookmark, but it does not behave (creates havoc) when sorting your bookmarks with the "SortPlaces" extension https://addons.mozilla.org/firefox/9275 which has to be able to rearrange bookmarks, I have over 2500 bookmarks which would sort in 1 sec which is far more important to me than watching for an unwanted duplicate. SortPlaces can be invoked manually or automatically -- users who use it automatically I expect would have no idea of what is happening.

This review is for a previous version of the add-on (0.7.4). 


Experimental prevents automatic updates Rated 5 out of 5 stars

As long as SortPlaces remains in Experimental status you will have to check for updates yourself as automatic updates will not occur, nor will experimental extension updates be found with the "Find Updates" on your add-ons.

This extension is invoked manually from the status bar, or moving button to toolbars from customization. The option to make sorting automatic may result in longer times to create a new folder, extending the delay helps with that.

There is some misconception of the use of "Sort by Name" in bookmarks context menu which nothing to do with this extension, nor does this extension interfere with that, though this extension makes that built-in feature redundant and actually takes longer than sorting all your bookmarks with SortPlaces. "Sort by Name" in FF3 must be invoked from a folder, never from a bookmark. FF2 allowed you to do either. More information on that can be found in http://kb.mozillazine.org/Sorting_and_rearranging_bookmarks_-_Firefox
