Hi

Are you using any custom userChrome.css in Firefox?

i don't think so, but if it is used in a custom theme, then maybe. i have a Dr. Who theme currently, i also checked out SpaceCat theme, and both of them are hosed the same way... i checked several of the 'default themes, which appeared to work, so i'm temporarily using one of those. i'm guessing this newest update borked some of the older custom themes... now i have a sad < le sigh >

and just to be preemptive: i have no interest in doing some delicate surgery with CSS to solve the issue; i'l just live with it and bitterly shake my fist to the sky.

Hi

I understand that if you are using certain dark themes you may experience issues with text contrast in the sidebar.

A workaround is to use the built-in dark theme or the system theme

This is tracked under Bug 1971487 and a fix will follow in a later release.

Hello,

The issue should be fixed with the 140.0.1 release. Please update your Firefox and let us know how it goes!
