Really useful, even though the colour spectrum is not as functional as it used to be. However, has anyone else experienced occasional flickering between tabs? I know it's not malware. Is it a function of trackng on other sites. Usually an issue when a site is opened which is video heavy. Any ideas, thanks.

Amazing

This used to be a great extension. It no longer works on the latest versions of Firefox (I run Firefox 66). I will not contribute to the support of this extension until it once again works as it used to work.

A year ago I indicated that this add on doesn't do anything except colour the first (active) tab. It doesn't look anything like the screenshot, which is now several years old. The ratings & numbers of users is rigged.

Excellent, time saving extension. I couldn't work without it.

ColorfulTabs is a wonderful extension, but I'm on Firefox Quantum 65.0.2 (64-bit) and I'm still only seeing one of my tabs colored. This is disappointing; the screenshot should be replaced with one that shows the tabs as they actually appear, not as they used to appear.

Работает не так, как заявлено. Цвет имеет только текущая вкладка, остальные вкладки без цвета. Скриншот давно уже пора обновить в соответствии с актуальной версией FF

I have used ColorfulTabs for a long time. I cannot imagine being without them. Thank you.

Too bad it can no longer color all of the tabs but still a nice add-on.

Worked well until I "upgraded" to FF 65 - now just shows one color across all tabs.
