Comment 7 for bug 2033988

TEMPORARY WORK-AROUND:

It was suggested to me that perhaps creating a new Firefox profile would solve the issue. I tried that and it didn't, so this isn't a profile issue.

Although the issue disappears when I create a new *Kubuntu* user, that's not a solution, since creating new users when something goes wrong would cause a lot of work in copying everything over and getting everything set up and customized for that new user just the way you like it each time. I can't imagine possibly needing to do that any time there's a Firefox Snap update. Besides, nothing changed in my Kubuntu configuration to suddenly cause this issue. What happened to cause the issue was me choosing to allow the Firefox Snap to update, which changed something that causes Firefox to misbehave.

For the time being, I have a clumsy two-part work-around that at least gives me access to all the features in Firefox:

1. I *must* use a light Firefox theme so that I can see the contents of the application menu and the contents of the toolbar folders.

2. That doesn't, however, make it so that I can see the contents of the bookmark manager. To do that, I must *also* edit the ~/.config/gtk-3.0/gtk.css file and set the *window* identifier's *background-color* property value to *inherit*.

The *window* identifier's *background-color* property value cannot, however, be left that way on my machine because the Claws Mail and Geany and Zim programs have some errors in their code that cause Claws Mail and Geany to have some black artifacting and Zim to have transparent artifacting that shows what's behind the window through the program.

As a result, that property cannot remain that way when I'm not actively managing my Firefox bookmarks. It can't just be disabled either, though, because that causes the Firefox Snap's tooltips to be black text on a black background, making them impossible to read, so, for instance, you can't hover over a link and see where it will take you. Instead, its value must be changed to a color lighter than black.

It's not a solution, but at least it's a work-around. The way my Firefox currently runs, I'm forced to always use a light theme (see above) despite my preference for a dark theme, and I must edit the gtk.css file every time before and after managing my bookmarks (see above). This is far from ideal and wasn't necessary before updating to Firefox 117.0 and is still necessary in Firefox 117.0.1. I'm providing this information, though, in case anyone else runs into this issue and wants to be able to see the contents of their menu folders and to manage their bookmarks.
