Hi Joschen,

You're currently posting in the English forum and we can't guarantee that a community member who speaks your language will be able to assist you here.

That said, it looks like you're dealing with a bug that our team has recently discovered. The good news is, our team is going to roll out a fix in a later version this week. In the meantime, the workaround is to use the built-in dark theme or the system theme.

Please check out the Unresolved section from our 140 release notes for more information.

Hi Kiki, thanks for your informations. I try to answer in english (but my english isn't not so good at all). So I will wait until the bug will be fixed. But give me an hint, where I am able to post any firefox-problems in a german forum ? B.t.w. the problem seems beetween a combination of 'Themes' and 'Sidebar' ... for example: when I use the 'theme: Katana 006' .. and use the built-in dark theme or the system theme, the sidebar is black, also the folder and the lines of websites. When I use the 'theme: Red Panda Simple' (using the built-in system) I will see all the folders and Entrys very well, because the background of the sidebar (theme: Red Panda) is white ! I'll leave the settings like this for now until the Firefox problem is solved.

Greetings Jochen

English isn't my first language either, and I can understand you just fine, so thank you for trying. (:

If you go to the following article Get community support in German, you should find a link to the German local forum from there.

And you're right about the combination of sidebar and theme in this issue. I've been told that an update that'll fix this issue will come out as soon as tomorrow. So please keep an eye out for it!

Guten tag, Jochen!

I have the same problem. I thought I was losing my mind.

Best wishes from Hollywood
