Why can't Firefox copy text to the clipboard anymore? It won't copy text from a web page, from a URL, or even from about:support "Copy text to clipboard"!!! I'm using version 1.22 64 bit on windows 11. I've reinstalled Firefox but it doesn't make a difference. I've tried "Troubleshoot Mode" and it's still broken!!!

I can paste into Firefox but something has broken copy!

I often like to have 2 browser windows open with multiple tabs going on each window. Recently, however I noticed that whenever I watch a video in full screen mode on one monitor then I switch focus to the second browser window to do other various activities, the video playing on the other monitor will sometimes exit out of full screen mode and continue playing in the original embedded small screen size. So far I've tried disabling all but the most essential extensions, put the theme back to the default mode, made sure my graphics card is fully updated, and even attempted a few setting changes people have recommended for fixing similar issues, but nothing seems to work.

As of right now, the only workaround would be to use the picture in a picture mode and put that to full screen, but that isn't ideal as picture in picture mode is set to be "always on top". I could also use a different browser, like Chome on my second monitor which doesn't seem to cause the video to exit full screen mode, but again, I typically prefer to use firefox for most things online.

Anyway, I'm now out of ideas on what to try to get firefox to behave in the way I want it to.

I have some Bookmarks on my laptop. I have some of these Bookmarks (Not all) on my tablet, plus some other Bookmarks.

If I sync them, which direction does the sync work in? Will all my Bookmarks on my laptop now appear on my tablet (Which I do not want to happen)? Will all my Bookmarks on my tablet now appear on my laptop (Which I do want)? Will I end up with two copies of most Bookmarks, because all my laptop Bookmarks are transfered to my tablet, plus all my tablet Bookmarks are transfered to my laptop?

I cannot find any explanatioin of what Sync actually does.

Stop tabs from automatically refreshing to top of page. Many people have this problem and I don't find a fix. One article states to go to Options and "Warn me when websites try to redirect or reload the page," but I can't find options.

Hello, Firefox randomly downloaded a file, with seemingly randomly name, that is 0 bytes and in download manager the source is moz-safe-about. It happened when I was accessing a popular wiki site. I opened the file in notepad, it was empty. I put it on virus total and came back negative, as it is an empty file. I've curbed through the support tickets here, using the keyphrase 'moz-safe-about'. I understand this was/is quite a common problem, but it still makes me quite worried and left a sour taste in my mouth, as I haven't understood any of the explanations. I have enabled firefox to ask me whenever it wants to save something (I have no idea why this isnt the default state). Happened on a somewhat fresh, updated win 11 installation. I'm also attaching more information here with a picture. Long story short: should I be worried? Am I overreacting and this is just some sort of a bug that occurred while getting a sites data? Thank you for your time.

Hello all. I'd like to restore the backspace button function but the previously workable solution — resetting browser. backspace_action to 0 — is not working for me. Any hints as to why that might be the case?

I removed the Firefox Relay, however whenever I want to open my email its still there and I have to keep entering my email address manually, How do \i get rid of it?
