My Reviews


Rated 5 out of 5 stars

I've been using CsFire for many years. It works simply, efficiently, and with few problems: In over 5 years, I've had to add maybe 6 exceptions (simple custom rules) to get sites working.

The developers also have been responsive to problems.

Thanks for your excellent work!

APK Downloader

Rated 1 out of 5 stars

While I appreciate redphx's efforts, I can't seem to get APK Downloader to work. Earlier versions downloaded nothing; version 2.1.7 is only downloading an HTML page for an HTTP 403 - Forbidden error. I'm using Firefox 43.0.1 on Windows 7 x64.

I've also been unable to get a response from the developer for support, and don't see any other options for support. That isn't a complaint - I don't expect support for something I didn't pay for - but it's relevant to a review of the add-on.

Thanks again for your efforts.

(When I wrote my earlier review, I hadn't checked what I downloaded and assumed it was ok, but it only was the error page mentioned above.)

Version 2.1.7 works great, after undiagnosed problems with earlier versions. Thanks.

Bottom UI

Rated 5 out of 5 stars

Just click download, and in a moment your tab bar and location bar will move to the bottom of the Firefox window.

I've wanted to try this layout for a long time, because I prefer to focus on the web page content and not on the browser's buttons, tabs, etc. Also, it might help others using this addon if they use keyboard commands to access the location bar (CTRL+L or ALT+D) and to switch tabs (I use the addons SwiftTabs and All Tabs Restorer); using the keyboard, it doesn't matter where those controls are located.

It would be helpful to be able to control which bars are on top: Tab, location, and any other bars at the bottom of the screen, but the default happens to work best for me.

Bottom Tabs

Rated 5 out of 5 stars

I'd been looking for something like this for long time. For Firefox browsers later than version 28 (i.e., versions with Australis), see tumpio's other add-on, Bottom UI:

All Tabs Helper

Rated 5 out of 5 stars

All Tabs Helper has an amazing amount of well thought through, useful functionality, yet it still feels fast and lightweight. It's impressive software.

It's a little difficult to access that functionality, which is hidden in a side panel and in the All Tabs button (also, the interface is a bit cramped, with small targets, etc.). I'd love to see the following, but the first would be transformative:

1) Make ATH a permanent sidebar (i.e., one that would not disappear when I open the Bookmarks or History sidebar). If you think about it, that's the only UI difference between ATH and the vertical tab bar addons, and ATH would be the best vertical tab bar I've seen. I've tried the leading contenders, and they seemed slow, heavy, and also seemed to cause crashes; I uninstalled them all. ATH also has better features: Search, sort, etc. (I'd use ATH as a vertical tab bar now, but it disappears when I open Bookmarks or other sidebars.)

2) Add an interface that shows tabs in all windows, not just in one. That would be very handy in combination with the search tool, and also if I could move tabs between windows. Perhaps use the multi-column interface from Tab Groups Helper?

It's easy for me to make suggestions for you to implement, of course, so all I really can say is: Thank you Allasso! Yours are some of the best add-ons I've seen. (Where's a donation link?)

tabs closebutton restored

Rated 3 out of 5 stars

Thank you Toshio; I'm glad to have the close buttons back the way I like them.

It worked, but in the end I had to manually create the preference. Here's what I did, using Firefox 31.4.0 ESR

1) Without downloading this add-on, I tried just manually creating the preference, with value 1 (I want the close button on every tab). Firefox would display the close buttons on every tab until around 8 tabs were visible; with more tabs visible, FF displayed the button only on the active tabs. (I'm not sure if that was the behavior before I created the pref.) I tried restarting FF, but nothing changed.

2) I removed the pref (in about:config I right-clicked on it, clicked Reset, then restarted FF). The pref was gone.

3) I installed this add-on (i.e., "tabs closebutton restored"). No pref appeared in about:config, but now FF displayed a close button only on the active tab, as if the pref was set to 0.

4) In about:config I manually created the pref, browser.tabs.closeButtons and set it to 1. Now everything works fine.

Random Agent Spoofer

Rated 4 out of 5 stars

It's an interesting idea and seems to work so far in Firefox 31, in very limited testing. Thanks so much for thinking of this and doing it.

A few bugs and suggestions:

* Most of the user agents used by RAS are very rare, such as Epiphany 2.3 on OpenBSD. With that user agent, my browser is easy to uniquely identify, without the use of any additional characteristics. It would be useful if the RAS user could easily narrow the user agents to those currently in wide use. (I know RAS will change the UA, which definitely reduces exposure to this problem.)

* The list of user agents is outdated. For example, on Windows Chrome UAs are 1-3 years old (RAS uses versions 18-33; Chrome's current version is 40), and Firefox UAs are similarly outdated. Again, using obsolete and therefore less common UAs makes users easier to identify than if current UAs are used.

* Unchecking all those boxes one at a time to exclude UAs (e.g., I didn't want any Unix UAs) is slow. An interface to make it quicker would be appreciated.

Rated 5 out of 5 stars

ShowIP seems to work as well as ever.

After install and Firefox' restart, ShowIP politely asked to install the AdBeaver adware. I declined, I see no sign of adware, and ShowIP works fine.

I have no objection to the developers seeking payment for their hard work, as long as they do it openly and honestly. If you don't want to use the adware, consider donating.

To the devs: If you could monetize it without impacting my privacy, I'd do it. Perhaps at least include a link to donations in the window asking about AdBeaver.

Print Edit

Rated 5 out of 5 stars

Print Edit is a wonder of imagination and execution. If you haven't tried it, it will exceed your expectations. It's hard to believe an add-on can do something this complex, and do it this easily and flawlessly -- and for free!

I wish I could use Print Edit in every other application I print from. Thank you!

Rated 5 out of 5 stars

It works well in Firefox 31, with one minor bug I found:

The setting, 'Breadcrumb for ...' doesn't work. Whether I choose 'host' or 'each segment', it shows breadcrumbs between each segment.

But overall, I love it. Thank you Dao!

Link And Forminfo

Rated 5 out of 5 stars

I've been using Link and Forminfo forever, and it does what it says well and reliably.

To the author: It's a little hard to find. I had to reinstall it and searched for "link and form info" (note the space between "form" and "info") and didn't see it. I almost gave up and used another extension, but tried one more time using a search engine and found it (using "link and form info").

Link Alert

Rated 5 out of 5 stars

Link Alert conveys the information effectively without distracting me; I know what the link is without thinking about it.

One suggestion: Make the icons for secure sites and insecure sites more visually distinctive. There is only a tiny difference between them. Perhaps make them dfiferent colors?

Thanks again.

Cookie Monster

Rated 5 out of 5 stars

Thank you so much for developing Cookie Monster (and then giving it away!). It works beautifully.

One question: Is there a way to disable or re-assign the ctl+shift+M shortcut? It conflicts with another add-on of mine.

And a related request, while I'm at it: A way to assign a keyboard shortcut to 'temporarily allow cookies from (this second level domain)'. It would save me a few clicks frequently.

Thanks again.

Domain Pass Lite

Rated 3 out of 5 stars

DPL is a really good idea and it's worked well so far; thank you. I know it's brand new software, so I thought some feedback would help:

* I can't remove domains from the Filter list. I've tried >Exception and >Reset; both work briefly, but the domain returns to the Filter list by the time I load a few more pages. I tried with and

* I've successfully added several hostnames to the Filter list and IIRC I successfully removed (or maybe I removed it from the Exceptions list).

* Finally, I don't think I added to the Filter list, but it's there now. Maybe I made a mistake someplace along the line.

Thanks again!

Open Tab Count

Rated 4 out of 5 stars

Does what it says; thank you!

For those who want to customize the color, etc., it takes a little skill but it's not hard. (Follow this procedure at your own risk! If you're not sure of what you're doing, I'd backup your profile first!)
1) In your profile folder, in the extensions subfolder, find the the file
2) Backup the original, and then make another copy to work on.
3) On the working copy, rename the file extension to .zip and extract the files (this works for all XPI files, afaik)
4) \chrome\chromeFiles\content\ has most of the potential customizations. Make changes (see below for ideas)
5) In the zip file (step 3) replace the original files with your updated ones from step 4. Save a copy and remove the .zip extension. The extension should now be .xpi
6) Exit Firefox. Replace the original XPI (step 1) with the new one. You did backup the original, right?
7) Start Firefox and you should see the results of your changes.

Some possible changes:
- in tabcount.css you can change the color of the font by editing the following line. The 6 character string is the hex number for the 'web color'; change it to the color you want. Here's a guide:
#tabcount { color:#CC3300; }
- you can eliminate the icon by opening browser_overlay.xul and removing or commenting out this line:

Skeptical Science

Rated 2 out of 5 stars

Interesting idea for an add-on. Unfortunately, on my computer it causes Firefox 4.0 beta 6 to frequently hang or pause, even when just opening a new tab.

Change Referer Button

Rated 4 out of 5 stars

Very nicely designed: Simple, straightforward, and efficient. I can change the setting in one click. One missing feature, from my perspective, is a whitelist: A site I use throughout the day requires the referrers. It's too cumbersome to remember to enable referrers every time I click something on that site. For my purposes, I need CRB to remember to allow referrers in that situation. But that's just my particular needs; it works very well otherwise.

ErrorZilla Plus

Rated 5 out of 5 stars

Great idea for an add-on; it should simplify dealing with broken websites. It would be helpful if you could incorporate a couple of features from Resurrect Pages (
- More cache websites
- Access to ErrorZilla from any page via the context menu (in case of non-standard error pages or any other time someone might want access to these features).

TinyURL Generator

Rated 5 out of 5 stars

It works very simply and effectively; thanks!
