  • 2 stars because it is compatible with 62.0.3. But it doesn not work as the picture shows....it only colors the active tab AND the menubar, URL bar... and all the other tabs look like they used to before this add-on was installed.
  • Can't deactivate the terrible sidebar "feature", so I am done with ColorfulTabs.
  • не работают цвета вкладок,все вкладки одного цвета
  • waw
  • Are you serious? We have to enter the hex number of the color? How the hell are we supposed to know that you need to have a GUI interface with a slider so we can just pick the color of and the Hue by looking at it not by studying a chart of numerals. LOL. This is like going back to the Heyday of dos programming
  • Из-за ColorfulTabs вкладки мигают между собой и приходится завершать процесс Firefox.
    Because of the ColorfulTabs tabs are flashing between themselves and you have to complete the Firefox process....
  • A 2004 favorite.
  • Makes Tabs flash and Fries Facebook
    Facebook was not working in Firefox. Obviously I suspected an addon but I did not suspect ColorfulTabs, but I thought I would check the reviews just to see. I started reading the reviews and I realized, thanks to previous reviewers, that ColorfulTabs causes Firefox to flash between tabs at random like this
    So I turned ColourfulTabs off. I now also realise that it was ColorfulTabs that was preventing Firefox from displaying Facebook! I don't like the way that the default Firefox tab display is white on black but other than that ColorfulTabs did nothing for me anyone (it only colors the active tab and turns the others black on grey). Goodbye ColorfulTabs!
  • Change le thème de Firefox même après désinstallation de l'extension.
  • I must second the review of 16 days ago. Once I get ten or more tabs open in Firefox 61, Colorful Tabs causes me to lose control of Firefox, as it continues to cycle through tabs all by itself. Impossible to stop this buggy add-on from taking control of Firefox. Once I disabled and removed Colorful Tabs, the random cycling through tabs ceased. This only happens once a lot of tabs are opened. But the bug is serious enough and disruptive enough that I made the decision to remove it.

    I wasn't using it anyway. I liked the way it used to be where the tabs them selves were colored. I understand Mozilla changed their code, making the old implementation impossible to implement.
  • This is a damaging extension - it enters Firefox into an infinite loop: focus changes from one tab to the next in a random order about one switch per second. Restart fails to fix problem. Had resort to work offline + restart. Even now that it's deleted it still has changed the colors of my active tab... each tab is the same purple as every other tab but at least it's not jumping every second now.
  • I almost added this one until I read that Firefox wants control over my laptop; i.e. "access your data for all websites" and Access browser tabs". Forget it! Too bad.
  • I used to love Colorful Tabs until it stopped working with the Firefox changes a couple of years ago. Since then it has been rubbish, I'm sad to say. All it does is colour the current tab and all the others stay grey. I want them all coloured the way they used to be, to distinguish them from each other.
  • Thank you, THANK YOU!! for taking the time to update this much beloved extension in the new FF! I so appreciate that you took the time to rework all the programing!
    THANK YOU! LOVE this extension!
  • Would be nice if it didn't override any theme set. Have it disabled now because of that.
  • The new version of ColorfulTabs shuts off my themes it didn't in the past but when it updated several months ago it just messed with Firefox theme, I had to disable it in order to get more than a white border at the top of my browser page. No way to contact anyone for a fix I tried all the online suggestions but nothing works. I guess it's time to remove it altogether until they figure out how to make it work properly. Months ago I would have given it 4 stars but now it gets one.
  • organiza todas as abas em cores. abre uma barra lateral esquerda com cada aba em forma de arvora de diretórios e cada uma com a respectiva cor, sensacional
  • It brakes firefox theme for me.
  • This add-on could have color tones configuring the loading time of web pages. Example: Fast pages have the green tab. Slow pages have red tab.
  • vivaldifox much better, and working.
