Ever since the update my tabs have been completely black and unreadable aside from the one I'm on. It makes switching between tabs insanely annoying and its so hard to tell how many I have open and what they are. I'm visually impaired so it's even worse. Is this supposed to happen? How can I change it? Image enclosed.

Hello, click on the hamburger menu, then click on Customize Firefox, at the bottom there is a drop down menu called Themes, click on it and select the Light Theme. If this solved your problem, mark as solution so others may solve it for themselves!

I had the same problem and got help from philipp.

I had to disable the addon Colorful Tabs. See here.
