Whenever i change Firefox window sizes(moving to second monitor) or full screen on other videos, random YouTube videos in the background will start unpausing and randomly playing.

My firefox installation failed to play any videos. It would load the video forever (longest time was 15 minutes) and never actually play; this persisted on all media sites I tried and was exclusive to firefox (other browsers worked fine). I reinstalled firefox entirely as a last resort. I now cannot sign in with my account to sync any of my browser data.

I use firefox on three places: macOS laptop, windows PC, and mobile phone (ios). When I try to sign in on the windows PC (the new installation), it lets me sign in and then says the sync failed and I need to sign in to sync data. It forces me to verify my sign in every single time. even if I just signed in and hit the sync option, it makes me sign in and verify my account again. It has been an hour of troubleshooting and I'm so goddamn frustrated with this. Never had any issues like this in the eight years I've used FF, but this mess makes me want to switch browsers entirely. IDK what to do.

A couple of weeks ago my Firefox desktop suddenly stopped loading images correctly. This is especially true for image-heavy websites like Tumblr. Images will either not load or only partially load. It takes several refreshes to get even 75% of images to load properly (including Shift+Ctrl+R). My Internet connection and speed are normal. Weirdly, other browsers loaded images fine at first, but now they're laggy, too? They still work better in comparison, though. And the Internet on my iPhone and iPad are perfectly fine.

I've tried all of these multiple times: Restarting my PC, Internet, and router. Disabling certain extensions (especially those for Tumblr and ad blockers). Restarting in Troubleshoot Mode without extensions. Reducing number of tabs.

I tried the different Profile trick I found Googling this issue to death, and it works, but I want to fix my default profile's issues if I can. Oh, and YouTube is insufferable to watch and crashes the browser, but I suspect that might have to do more with what YouTube's trying to do with ad blockers. Especially since Chrome isn't much better on that count (aside from the crashing).

Edit: This issue started occurring around the time I downloaded the last Firefox update before the latest one. I thought installing the latest one might solve the problem, but it didn't. This might just be a coincidence.

I want you to be aware a Northern Calif. Utility, PGE, has rebuilt their website so FireFox cannot be used. I do not know if this is legal. I can no longer pay my bill using their website, and by phone, I am charged a fee. I don't know if this is legal, but you should not want this happening to the only safe browser.

I find that I can not run or even access the macro function in google sheets. These functions work fine in all other browsers. The menu items are grayed out and just like the macro buttons, they do nothing when clicked. I find many other talking about this with no resolution. I do find it odd there there is nothing listed about this omission in the Firefox help forums.

I just wasted 3 hours trying to figure out why my ComfyUI (local AI image generator) stopped working with Firefox. There were no error messages from ComfyUI, it just failed to load workflow files.

It turns out that it's because Firefox is installed as a snap package and wherever the snap configuration for Firefox lives thinks it knows better than I do what files and directories on my system I can access in Firefox.

I also had this problem with trying to open PDFs in my home directory where I kept getting access denied errors. I tried to solve the problems with the snap version and found several proposed solutions by google search which people claimed worked but did not.

I finally found a web page that described how to uninstall the snap package and install an alternate non-snap version of Firefox, and now everything works like I expect it to.

How do I make sure this snap version does not ever come back?

I have been using a usrChrome.css in my profile to create multi-row tabs. (Why cant Mozilla see the need for this with 4K monitors?) The Oct update broke this and I cannot get FF to load the css file that has worked for more than a ywar.

Help please?

Sometimes drag functionality stops working. I can't grab a tab to move it to another position or to a new window. (Holding left click on the tab and moving the cursor does nothing). Also, re-merging the tab with another firefox window stops working. (Dragging a tab to a firefox window from another firefox window doesn't merge them. It does nothing) I can right click on the tab and select Move to move it to a new window but dragging stops working. I have to close Firefox and start it again (sometimes twice), then dragging starts working again. This happens multiple times a day. I am on Linux Mint and the version is 126.0 (64-bit). This problematic behavior has only recently began.

When I go to listen to my KQED passport films, I used to be able to hear the dialogue at less than 50%. Now I need to turn it up to 100% to even vaguely hear anything. I was wondering if there is any way I can make it louder. This happened only recently. Thanks for any suggestions.

I have followed various instructions I found (such as stopping all add-ons etc, starting firefox in safe mode etc etc), but still no joy.

When I click on a link in an email (outlook although not relevant I dont think), Firefox opens a new instance, starts in first tab with my default home page and then .... nothing. If I copy the selected hyperlink and put it in the search bar it works fine. More importantly, if I change *all* my defaults to say Chrome and try, it works fine.

Any suggestions on what I am missing from the various solutions? (Been happening for ages - maybe a year or more I think).

Hi there! It started yesterday. I keep getting warning messages from Bitdefender that a connection Firefox was trying to establish was blocked. I will include a screenshot of the warning. I searched the link included in the warning and it comes up as a Firefox related link. I had six or seven of these warnings within the last 3 hours of using the computer and am concerned and irritated. Firefox is updated automatically on this computer and I think the last major change would have been the "cookie jar" thing(?). Obviously, the warning only says that the a certificate has expired. Thank you in advance for your help. Yours sincerely,R.

I have noticed that many a times (even with the latest update installed) randomly etrade website does not load. Not sure why? I have deleted the history etc and still...

On the bottom left I see "Read c.evidon.com" the hourglass in the tab.

Hey guys,

I kinda need your help. I just switched from Windows to Manjaro Linux and I cannot retrieve my Firefox bookmarks and passwords. I do not have access to the old setup because I have formatted the disk and I have only this one on Linux.

I have used my Firefox account multiple times in order to login on a new device and every time it has retrieved my bookmarks and passwords but not this time. Before logging in from this device I had to reset my Firefox password because I had forgot it -- is this a security measure maybe?

Are my bookmarks and passwords gone forever? Thanks!

I've been seeing this more and more, but my toolbar will change by itself every restart. The add tab button will shift all the way to the left or not appear, the bookmarks won't appear, etc. I'm not sure what can be causing this, and I saw no way to "save" my current configuration other than pressing the done button upon using the custom toolbar, which I had done every time prior to fix my configuration. Does anybody know why this is occurring, and a possible fix? Thank you

On 2015 MBP Mac OS El Capitan 11.6 new Firefox 78.15.0 esr won't sync with my older MBP running El Capitan 11.6 but it will sync to the 2015. How do I get the 2015 replacement computer to sync?
