Dark Background and Light Text

Excellent idea. Here are two suggestions.... Rated 4 out of 5 stars

Of course, it must be impossible to make this add-on work on every website--as some of them have text images instead of ordinary text--but it works on 90% of them. Some websites have images that appear invisible when using this add-on, including "text images". Suggestions: 1. Please make your add-on reverse all images, so that we can at least see them, even if they are not very pretty. 2. Please include the option in the global preferences, of using BOLD text throughout, in order to make the pages even more legible.


Brilliant, but does not often work automatically Rated 4 out of 5 stars

Thank you for the ingenious solution to this pitiable trend among website designers more concerned with form than function. I must agree with others in pointing out that this add-on does not always work automatically, nay, usually does not work automatically; I must select the menu item from the context menu usually. Yes, I hope to be able to send you examples in the course of time, but, in the meantime, I assume that you could come across some yourself eventually. My hat goes off to you for your sense of practicality.

The Washington Post (SSL)

Horrible Rated 1 out of 5 stars

Skips over big news to highlight trivial events. I need real news. Sorry, but thanks for trying.

TableTools2 - Copy/Sort/Chart/Filter Table&More!

Can hide table columns, but cannot hide rows. Rated 3 out of 5 stars

Hiding rows is what I needed the most. Otherwise it was a great add-on.

Close tabs to the left

Adds obnoxious confirmation dialog boxes! Rated 1 out of 5 stars

Every time you use this add-on, you must first respond to a confirmation dialog box that cannot be disabled, which says, "You are about to close 2 tabs. Are you sure you want to continue?" If you allow the confirmation dialog box to be disabled, I will go back and give the add-on five stars. Otherwise, I cannot recommend this add-on when one called "RemoveTabs" does the same thing without the obnoxious confirmation box.

Nice, but very slow Rated 3 out of 5 stars

Nice add-on, and apparently one of a kind. For that I certainly congratulate you. However, half the time I have to manually apply Blacken to any given page, using the context menu, because otherwise it takes up to sixty seconds to work, sometimes even more. Other times it works faster, within about ten to fifteen seconds.

Wikiwand: Wikipedia Modernized

Thanks! Nice, but has problems... Rated 1 out of 5 stars

(I am going to rate this add-on with only one star for now, but raise it to four or five, after I get a response to my observations below, just to help insure that this gets read.)

I am using Firefox 44.

Now, correct me if I am wrong....

The add-on looks great, but now the option of clicking to open any Wikipedia image in a separate tab, is gone from my context menu. I cannot even recover it with TabMixPlus or other add-ons.

Second, Wikiwand makes Wikipedia pages load more slowly, as it has to re-format the page. It might be better if it loaded all the text first, and then concentrated on the small details. At least I could begin reading immediately.

Third, Wikiwand now hides information that was formerly kept open and in view at all times, such as "references," and "external links". Not the end of the world.

Fourth, there are obnoxious arrows on either side of any given page, which provide quick links to other Wikipedia pages that I have recently opened. Whenever I hover over them, even briefly, these pop-out windows obstruct my view of the main page. Because of their proximity to the Firefox vertical scroll bar, they also make it harder to use the scroll bar.

Fifth, the caption for the main picture atop each Wikipedia page, is now missing. The picture itself is enlarged and nice, but now we no longer have a quick reference to what-in-the-world the picture depicts. This information was formerly available in the top right-hand column of any page.

Perhaps a solution to many of my observations would be simply to allow more options in the "preferences" to your add-on; such as for hiding the pop-out windows, allowing captions, keeping certain sections open at all times, allowing photos to open in new tabs, etc. The options that you provide are a bit more limited than I would have expected.

All in all, don't misunderstand; you have done a great job, and I am still grateful to have it, even with the minor shortcomings.

Tab Mix Plus

Tab focusing is not working as designed Rated 4 out of 5 stars

I de-selected the option of "Focus tabs that open from bookmarks/history" but, whenever opening a link from my "history" window, Firefox v.44 still focuses on the new tab.

Google SSL,en-US,verbatim

Simply wonderful Rated 5 out of 5 stars

Instead of presuming that most users will spell correctly what they are looking for, and that a few will not, Google assumes the opposite: that most users are morons; "If they search for one thing, they probably mean to search for something else, instead."

Consequently, if I search for "pickles," (for lack of a better example), I may be presented with search results that begin by saying, "Did you mean 'pickled'?" or "Are you sure you didn't mean 'pick-axe'?"

In other cases, Google will not even ask me whether I was sure, but will simply show me every thing from "pickled" to "pickling," in the results. Of course, I don't catch on, for thirty seconds or so, as I read down the list of search results, assuming that Google did the search correctly. Then, I finally realize that this is not the form of the word that I had searched for, to begin with.

Along came some brilliant executive at Google, who, after years of giving the users not what they searched for, but rather, something else, finally said to himself, "Eureka! I've got it! Why not allow our users to obtain results according to the very words that they type into the search field? In other words, rather than presume that our users are idiots, and that they don't know how to spell, why not make our search engine do precisely what it was supposed to in the first place? Why, what an ingenious 'tool' this could be for all the world! I might even win a Nobel Prize! We could call it a "verbatim-search tool..."

Of course, the Board of Directors at Google was probably unhappy that their product was now beginning to do what it was supposed to have done in the first place, so someone on the Board decided that, if this nifty "search tool" was to be employed, it should, at least, be hidden; it should not be available on the initial screen; users should have to go looking for it somehow, clicking around, here and there, until they finally found it.

Oh, but then Mr. Kang came along, and ruined Google's plan forever. Thanks to Kang, we can now go directly to the "verbatim search" by default. Someone at Google must be furious, but the rest of us are delighted. God bless Mr. Kang.

And, of course, Google still assumes that anyone using their website in Mexico must be a native Spanish speaker, as anyone in France must, of necessity, be French, and could not possibly be an American businessman, for example, flying into the capital city there for a business meeting, using his laptop on the plane, as well as in his hotel room, or in the meeting room. "Of course not; by Google definition all users in Mexico must be Mexicans; all users in Paris must be French; they must be forced to use the Spanish or French search engines by default, regardless of which language they prefer."

Of course, one could probably "sign in" to Google, in order to save his search preferences regarding region, language, and "verbatim searches," but by doing so he allows Google to track his searches for the rest of his life, "anonymously," perhaps, but, then again, linked always to his e-mail address that he used to sign in automatically--very useful information to the NSA these days, by the way.

In conclusion, thanks again, Mr. Kang, for thinking logically, and for taking the time to correct yet another gleaming oversight on the part of Google. It is amazing to see that no one else, among the add-on developers, thought about making such an add-on; everyone else seems to be content to go through several screens, just to make one search.

uBlock Origin

Nice add-on Rated 5 out of 5 stars

Thank you for clearing up some of the issues that I had with automatic site blocking. Thank you also for taking the time to develop this add-on, and for sharing it with us.

Zoom Page

Thanks! Rated 4 out of 5 stars

Thank you for generously taking the time to answer my other post.

Yes, I had read the bulk of your manual on the home page, when I wrote, but I still couldn't quite follow the settings, which brought me to suggest that you give us a few specific examples, even if it is only on the home page.

I've been working in graphic design since 1996, on two platforms, so I am not exactly computer illiterate, and yet I could still not make out the setting explanations.

For example, portions like this in your manual appear:

"Percentage → click → Zoom Menu → shift+click → Set Text Minimum Zoom Level"

Now, then, does the first part mean "Click the percentage key to display the 'zoom menu'"? If so, I would have expected it to read, "Percentage key + click = Zoom Menu," so you might understand my confusion.

And where you said, "shift+click → Set Text Minimum Zoom Level" mean, "Shift+click anywhere on the screen to set the text minimum zoom level"?

In either case, I could always go through the options, one by one, and through trial and error and by a process of elimination, discover what each setting meant practically speaking, but I just thought it might be easier to suggest giving us a bit of an example for each main point. Of course, if my PageZoom icons were displayed anywhere at all, it might be easier to try each function and see what it did, one by one.

In your response you also said, "Zoom Page allows the user to set the zoom levels to any integer percentage values," and I am sure that a fine add-on like yours must do that, but "how to set those levels" was my question. All I saw in the options window were a set of pre-determined values, one of which was the "FF standard" and the others of which were "custom" sets, but they seemed to be predetermined at 60%, 70%, 80% and unchangeable.

Anyway, I don't want you to lose any more time with me. Just keep up the great work, and I will find a way to make the add-on work for me.

Zoom Page

Nice but very complicated Rated 4 out of 5 stars

Thanks for your hard work.

I cannot find the ZoomPage icons anywhere on the status bar or toolbar. FF39. (I even installed a new status bar, to be safe, but no sign of ZoomPage, nor in the menus either, nor in the "zoom" sub-menu, nor as a "view" menu item, nor as a right-click context menu. Nothing.)

I would like to tweak a page where the width is ideal but the text needs enlargement (without enlarging text on other pages) No idea to do that with this add-on.

How to enlarge in smaller increments (e.g., screen at 85%, not just 80% and 90%)

Nice options dialog box, but it is missing explanations or examples of what the options really do.

Should have buttons on the status bar saying "Keep settings for this page as is" and "Reduce text only" and "Fit to width" etc. No context menu, no FF menu options, no icons on the toolbar, so I don't know where to go with it.

Obviously you put lots of hard work into it, and for that you are to be commended, not to mention for your generosity in providing it to us.

P.S. My OS is XPSP3 and my font DPI is set to 135% system wide, for better legibility without eyeglasses.

Close tabs to the left

Very good. Rated 5 out of 5 stars

A brilliant solution to a problem that never should have existed in the first place.

By the way, who was the original programmer that decided for all of us Firefox users that tabs should only be closed to the right, anyway?
