I liked Colorful Tabs for the variety of colors on the INACTIVE tabs, which made finding/returning to particular tabs very simple.
I don't understand the allure of just coloring the active tab?

After updating don`t work properly

If you love ColorfulTabs like I do and don't want to live without it, you have 2 choices. Both require ditching FF Quantum.

1. If you care about security more than speed, then as others have said, run FF ESR with CT 32.2.3. If you do this, disable auto-updates to CT.

2. If you care about speed more than security, run FF 56.0.2 (the last update before Quantum) with CT 31.2.0. This gets you the benefit of the Firefox multi-process mode, which greatly improves the speed and memory usage of the browser - at the cost of being stuck in a static configuration with no security updates. If you do this, disable auto-updates to both FF and CT. This is the config that I use every day.

Loved the old version, but the new version for quantum just does not do it well. Not blaming the developer per se I think it's a limitation with quantum. Before I like the multi-colored tabs, and the option to highlight in yellow or blink active tab. Old version 5+ stars new version meh.

Very bad presentation on the extension page Rated 1 out of 5 stars

This is the first extension I am reviewing without having tried it. I don't need to try it because colored tabs are not something I need.
This is a review of the extension page and the bad description posted by the author. Out of two paragraphs, there is almost nothing about how this addon works. The 1st paragraph is just generic nonsense and false praise about how this is the most important extension I'll ever need, and the first one I need to install. That is NOT a description, that is BS.
The second paragraph is a review quote from a user who loves this extension, for whatever reason.

Horrible presentation, no description to speak of, all BS and lies, nothing that explains what makes this extension SOOO good. This type of a front page is just very unappealing, and I'd never want to try any extension with that info.

Fail!

I should have made proposals on the site if I had found how to create an account.
This extension is a good idea (and replaces things that no more run), but needs to be improved.
By the way it appears that critics for two different extensions appear on the same page here.
I tested the one with Web Extension, as I use Firefox Quantum, version 59.0.2 - I presume this extension is somewhat recent.
About the results, I see the active tab displayed with a different colour, and this is why I installed the extension.
That being said, this background colour is at random, and the foreground colour (font colour) is fixed (in the options) so this not always optimum.
I regret not being able to choose colours for other tabs, classically a set of colours for not loaded tabs, another for inactive tabs ...
Tab Mix Plus has accustomed us to use a nice user interface to choose the colours, well let us forget that for the moment being, it takes some time to develop.
What would really be useful is that the extension sets a style name for the active tab, one for the tabs that are no more loaded, one for the other ones. And also that the documentation gives those style names.
With that, we could personalize properly those styles in userChrome.css (at least the advanced users could do that).
In a second time, as an options interface is proposed, it would be nice that for each of these styles it allows to give a foreground colour, and a background colour. Some of them miss. If time allows, some other attributes as bold could be smart too.
When this urgent stuff is done, I should like to mention that after installing the extension I had to style my personal bar (placestoolbar), as the extension modifies its background colour, and the font colour it had was no more adapted.
If you have time to do some tests at this level, it will help, too.
Thanks for the good job.

Bad colors. Not like in Vivaldi. Youtube isn't red, for example.

IT DOES NOT WORK

Rated 1 out of 5 stars

It does not work in Quantum. It overwrites my Personas theme with an aweful, random colour and does nothing for tabs. Useless, unfortunately. This was my favourite add-on prior to Quantum but is now nothing. Such a shame.

Quantum is horrible. It's like they deleted the fun stuff and and replaced it with... nothing. Even the bookmarks are inconvenient to use. I've been using Edge on my new laptop. It's better than this mess.

Rated 4 out of 5 stars

people still don't want to understand that at the time it's IMPOSSIBLE to color all the tabs through an extension as it used to be before quantum. maybe it never will.

blame mozilla for this... personally i'm sticking to 52.x ESR, stuff this quantum crap.

I like using "ColorfulTabs because each tab that's open has a different color. You can change the color of any tabs,
that are open, to a color you prefer. And if you have tabs for the same site, different pages, it will show a fading of different colors that the first page of that site has.

I just tried it again after disabling it some time ago. This extension is completely useless. Please REMOVE it until the author fixes it. All it does is mess up top toolbar area. Who needs that coloured when the active tab is already highlighted? When is it going to work with tree tabs? I used this to set priorities for tabs. The lack of response from the author is an insult to all those who have tried to help to get it fixed and sent compliments. Perhaps the author would do us the courtesy of telling us WHEN it will be fixed? Before we all stop bothering to check? Maybe tree tabs authours could put something in their extension to colour their tabs?

A once great extension, like MANY others, laid to waste by Mozilla with their lame implementation of the incomplete Quantum with most APIs unavailable to addon devs.

TO THE PERSON WHO WANTED TO KNOW HOW TO REMOVE COLORFUL TABS: Click on "Tools in the row of items at the top left of your FireFox browser. Click on Add-ons. Look for "Colorful Tabs in the list. Then over to the right, you can choose either "Disable" or "Remove." Personally, I only disabled it, as I am still hoping it will get fixed and it was great before FireFox elected to make the change to horrible "Q"! I was resisting Q, but thought certain problems with FF might be due to not agreeing to the change, so now I have Q, which gets updated, but FF seems to be still having much the same problems, anyway. Groan.

I have long used and loved colorful tabs, but now that only the active tab and bookmarks bar are colored, some of the colors are so strong that I can barely read the name on the tab. This is especially so in the case of the purple tab, and I wish there were a way to lighten or change any color that is making it hard to see the lettering. I think I made a donation shortly before this change occurred and am regretting it.

I am hoping this Add-on will get back to the great little tool it used to be before Quantum. I realize that that may involve a lot of work for its creator. (By the way, I detest Quantum and am tempted to switch to a different browser. Perhaps Edge, when I am inevitably forced to buy a computer running Windows 10 (ugh, ugh!). Anyway, until we are able to get back to what Colorful Tabs used to be, HOW ABOUT USING PASTEL COLORS to make the tabs more functional? Unless things change to be more legible, I am going to have to disable or uninstall this Add-on.

Doesn't work as shown in the extension page screen shot. Only the selected tab is colored randomly. The bookmarks and address bar rows are also colored with the same random color.
