Firefox Support Forum

OPEN PREVIOUS WINDOWS AND TABS is unchecked but upon startup firefox always tries to do this and I get an error message. Computer crashes, shutoffs, sleep mode and Firefox wants to go to my previous windows and tabs : I HAVE IT UNCHECKED FOR A REASON, I DON'T WANT TO GO TO PREVIOUS TABS.

Currently, when I try and open downloaded .txt files and .log files (that is, when I click on them directly from the download pop-up that appears at the top-right of the browser), Firefox inexplicably opens Aegisub on my machine as the app to use. This is in contrast to when I open it directly from within my file browser, where it opens the Kate text editor, as suggested by the default app option in the permissions of the filetype.

How do I change the apps Firefox uses to open downloaded files? I've tried going into my settings and looking at applications, but .txt and .log don't appear, so I'm not quite sure what to do.

I'm on Kubuntu 22.04.3 LTS, using the Firefox deb package.

Ever since Firefox browser updated, my Home (specifically Shortcuts) has been glitching.

They do not show up, no matter how many rows I add or subtract. Web search and Recent activity still works (to an extent) but Shortcuts? Never again. Please fix it ASAP.

Sometimes a box pops up on the screen that asks if I want to block or allow something. Sometimes I have no interest in doing either, and just want the damned dialog out of my face. The page seems to work otherwise, but the stupid browser keeps the dialog over top of things, and clicking outside of it, and hitting Esc, don't make it go away. I think those actions used to work, and I think there, sensibly, used to be a dismiss option, but that seems to be absent now. There's no sense to trying to force me to make a decision I don't want to make, and doesn't even need to be made, and I want this thing to cut it out.

The webcam video image is being reversed or being flipped horizontally when using the latest version of Firefox. This is not happening in other browsers. I reset Firefox, but the issue still occurs. Can you advise/fix please?
