Today I let Firefox update to the new Quantum version. As a result, I can no longer read my tabs (black on a blue background is hard for anyone, but my eyes are really bad, even with correction).. Plus, they have moved to an inconvenient location (above address bar). Before this update, I was using Colorful Tabs add-on, which made them all easy to read. In addition, I was using another add-on that allowed me to hover over the tab and it would show which page it was. Now, the only way I can see which tab is which is to actually click on the tab and go to the site. This is horribly time-consuming, and I don't have that much time to spare. Can you please advise how I can regain both the position and readability of the tabs on my tab bar? This system is awful as it stands now, and I may have to (reluctantly) start using a different browser. Please help.
