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.

BEFORE ANYONE ANSWERS THIS PLEASE STOP AND THINK. I have been using this browser since Netscape. I have been "managing" bookmarks for years and years but I have NEVER found a SOLUTION to managing bookmarks in a SIMPLE, USEFUL way. I have wasted hours and hours on this site looking for answers to the ongoing difficulty that EVERYONE has dealing with the BROWSER WARS imperative that bookmarks can be imported and therefore, perpetually duplicated in an infinite array of browser upgrades and OS installations over the YEARS AND YEARS. For those of us who have managed to ERR on the side of caution and always opt to live with the effects of this rather than risk LOSING the good data nested within, I implore Mozilla to THINK LONG AND HARD on developing a solution to this ONGOING PROBLEM WITH BROWSER BOOKMARKS MANAGEMENT OVERALL. Oh sure, there are hundreds of plugins that ultimately suck up the memory for partial solutions to the PROBLEM that is caused by each new installation of Firefox or other browser in which past bookmarks are imported and ultimately duplicated ad infinitum. I don't need to know all the things that are wrong with Microsoft and how developers or users create the problem, I need a SOLUTION.

Will Mozilla please be the FIRST BROWSER TO SOLVE THE DE-SHITIFICATION OF BOOKMARKS no matter how poorly mismanaged and duplicated they were in past iterations?

The more time I spend on this HELP site looking for answers, the clearer it becomes that this is a problem for DEVELOPERS to solve because none of the USERS can figure out the answers. So, BEFORE you tell me ANYTHING, SHOW ME THE MOZILLA FEATURE THAT SOLVES BOOKMARKS MANAGEMENT THOROUGHLY AND SIMPLY, because, so far, that clearly does not exist.

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.

Hi Windows 11. Every time I open a new tab and make a search I get a field under the bookmarks for my google account. I do not want this. On the web it says I should go to account settings and scroll down to the Linked Accounts section. I cannot find that section. Elsewhere I read that I have to do something in my google account as well. How do I get rid of the field for my google account when searching in firefox, please?

I have been a subscriber w/ copper.net email service for over 16 yrs. I am unable get in now, please help,it is VERY important.

I do not want my searches to be reflected in the address bar. I believe in prior versions of Firefox there was a checkbox to delete that provision. I'm using Firefox 123.0 64-bit with Windows 10 and have been through the setting and more tools areas but found no way to remove that function. I did try the about:config suggestions but still have no joy.

After latest Firefox update this morning, attempts to login to Fidelity.com fail with message "we can't complete this action right now". No problem if I use Chrome. I cleared cookies and rebooted. Running Windows 10. Fidelity technical support not seeing anything obvious but suspicious it is related to this latest update.

I have been signing in to a certain secure website for years on Firefox. In the last 24 hours, it won't let me sign in and all I see is:

"Bad Request

Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit."

I have tried 20 times. There is nothing wrong on the website; my wife can access the same on her Mac computer.

Any advice? Thank you
