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've tried EVERYTHING I can think of to fix this issue. When 'trying' to open a YouTube video in Firefox, I'm 'informed' that I'm offline - try reconnecting (or something like that). I'm NOT offline. Three other browsers have NO problem opening these YouTube videos; it's only Firefox. Can someone PLEASE come up with a REAL resolve to this issue? I don't want to give up on Firefox and go back to Chrome. But this issue is VERY annoying. Thanks to anyone who can provide constructive resolution(s). AL R.

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.

This has been going on for over a week. I have downloaded and applied the installation program multiple times (>3). The problem persists. What is going on, and how do I fix it? Thanks

For years, I have used print to pdf in Firefox to generate pdf files of long web pages. It always worked. But lately, I noticed that huge numbers of blank pages are inserted in the pdf file, seemingly at random. I looked at the HTML source, and could not see anything that obviously triggers the blank pages. For example, a web page that ought to print to about 35 pages generates a file of more than 600 pages, with most of them blank.

I can use Microsoft Edge as an alternative, but pdf files from that browser strip out all the color, and are nevertheless super huge, about ten times larger than the ones from Firefox. E.g. the file mentioned above, about 35 pages, would be about 1.3 MB from firefox, and 12 MB from Edge. So getting the file from Firefox would be nice.

Is there a reason why print to pdf is behaving in this strange way, and anything I can do about it?

For System Administrative reasons, I want to disable automatic Firefox updates. Firefox can ask me if I want to install an update, but I get to choose whether or not to update.

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?

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.

I have set Firefox as my default browser. I can open it using a shortcut on my desktop. However, if I follow a link from an email, it does not open in Firefox. How come?

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.

This is the message I get. "Please unblock challenges.cloudflare.com to proceed." I can do nothing.

Things I've tried. Adding exceptions in the privacy settings in 2 seperate areas. Resetting Browser deafults. Turning off all vpn's and addons.

Nothing works.
