It's not ColorfulTabs' fault! Rated 5 out of 5 stars
I mistakenly thought that the problem with really dark colors on the tabs was the fault of Colorful Tabs, but after I removed ColorfulTabs, my tabs were still in dark colors, so I looked further. The culprint was "FabTabs", which I immediately removed, added back ColorfulTabs, and now my tabs are their usual, beautiful, pastel selves. Yay for ColorfulTabs!This review is for a previous version of the add-on (6.0.1-signed). This user has a previous review of this add-on.
