Developer is delusional. Apparently it works but at the same time it is Mozilla's fault but we should vote 5 stars to not tarnish the reputation of the add-on. What?

I find this very unfriendly to those of us with suboptimal vision.

Instead of just giving each tab a different color, which is the way the developer describes it, this extension turns everything from the top of the window to the top of the web page the same color, and leaves all of the rest of the tabs white with black lettering. In other words, clicking on the first tab makes that tab and the rest of the top of the window Color 1, activating the second tab makes the second tab and the rest of the top of the window Color 2, etc.

The developer makes it sound like the tabs all have different colors even when inactive, which would have helped me distinguish between tabs without having to read the teeny tiny print on each one. It does ease my difficulty reading tiny white lettering on a black background, so at least Colorful Tabs does help, but black letters on most of the tab colors are almost as hard to read as white letters on a black background.

I'm just sorry I didn't notice that my settings had changed to automatic updates, because now I'll have to wait six months for enough extensions to be developed to make Firefox usable for me. In the meantime, I guess I'll go back to Safari for a while with my tail tucked between my legs.

I love love love this add-on, but it makes my themes turn white! I have reluctantly disabled it until it is compatible with firefox themes.

I use Firefox Themes. I used to like Colorful Tabs when it was just Colorful Tabs, but now, it turns off the Themes. It's bad enough that Firefox has eliminated the border and Status Bar on the bottom, to be a part of the Themes, but now, with Colorful Tabs installed, the entire theme disappears. It doesn't come back until Colorful Tabs is uninstalled.

My colorful tabs are gone! All tabs and the toolbar are now the same color. What happened to all my colors? I couldn't stand the one color so I disabled this add-on. Please change it back ASAP.

When enabled colorful tabs use to be usable while also using themes now when used for ver. 57 it disables any themes you are using. Colorful tabs are no longer very colorful since only 1 tag is colored. Not impressed so far.

Used to look nice...the new versions suck.

Fijne add on maar ik kan deze alleen gebruiken met de zwarte achtergrond in de nieuwe versie van FF. Niet te lezen dus.

I do not like. It can not, as in the old versions, choose color.

The new FF57 version no longer matches the old ... please change this :)

Since Firefox updated to 57.0 this add-on has stopped working altogether.

Unfortunately, also all bars are coloured and my theme is overruled.

I think you should confine yourself to the tabs only or build in a feat to adjust whether one also wants to change the bar colours and/or theme. Also only the current tab is coloured. the rest is hardly visible against the background.
So disabled it, unfortunately.

But I realize that FF57 causes you a lot of work and is restricted in how you may adjust feats like tabs.

Die alten Einstellungen waren prima. Jetzt mit FF57 ist es nur noch scheußlich. Nur noch der letzte Tab wird farbig angezeigt. Alle anderen erschein farblos. Ändert das bitte.
Mit freundlichn Grüßen SR

The app produces garish results. I'll be looking forward to a revision of a version for Firefox v 57 that works like it did in older versions of Firefox. Until then the flat appearance of FF 57 will have to do.

Suddenly quit working with update to Firefox 57. have tried reinstalling, etc, but no colors except the current tab.

The update for my Quantum still does not work properly. Disabled it again.

This was a 5 star extension before FF57, now we have a significantly faster browser but with a shockingly bad user interface particularly the poor tab placement (fixed with a chrome css bodge) and Colorful Tabs functionality is not even remotely like it was before. I have currently disabled this extension, switched to FF dark theme and with a wider tab text space.

Would have possibly reverted to FF56 but even witha 'new' install it's impossible to install and then disable upgrades before the FF57 upgrade is downloaded.

Miserable with Firefox 57. Not only has it taken control of the entire menu/favorites bar, it has blacked out the very top of the screen so you can't easily see the File, Edit, etc., NOR what's on the other open tabs. You cannot see the new tab field, either. HATE it. I have used this program for years and donated to it, so I hope it will be fixed at some point.

Hate it for now. Uninstalling. Also, not sure if this is related to this issue or something else inherently wrong with FF 57, but now all my bookmarks saved folders will NOT open. So everything saved within the folder cannot be reached. Woe is me.

The old Version uo to firefox was very great. Version 3 with Firefox 57 is horror. Wher can i find the (former) options/settings for individual outfit? In this time no use for the add-on, horror. U. Neumann

I LOVED the old Colorful Tabs. But now, I'm not so in love anymore. Until it colors the tabs like the original one did and doesn't make my theme black, I won't use it. Since I recently donated so it can be fixed, I'm hoping it will be fixed soon.

Same problems as everyone else. A previously great extension now severely damaged

New version to become Firefox quantum compatible not working properly. If you have a single tab, the entire tab + all of the window framing is colored, so can't read text, see icons, etc.
