Disappointed as this version only colors the open tab; previously ALL tabs were colored differently.

This is not the same. It has been changed. I just want the tabs colored like in the screenshot, not the entire window border.

so lovely, makes browsing less confusing with many tabs

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.

Why is this add on allowed to show outdated screen shots? It hasn't worked like this for YEARS.

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.
