YouTube has been so slow in Firefox. It just takes a ton of time for the video to actually play. It's just a spinning circle in a video. I can refresh several times and then it plays. I cleared my cache, history, data...etc everything from Firefox. That seemed to help for a bit. Then it just resulted back to being slow. It's just in Firefox. I played videos in Edge. It was fine. No issues. It's just FireFox. It started most recently too. It wasn't happening a week ago. I even tried going back to an old version of Firefox. Didn't help. Anyone know how to fix? Not using ad blockers either FYI. I just want videos to play normally and fast.

Windows restarted to update and all my 100s of tabs are lost (setting me back days of work!)... Firefox is set to always reopen previous tabs, but it didn't work. Recently closed tabs/windows are blank. The Restore Session page - about:sessionrestore - doesn't restore and lists no previous windows/tabs. I went into my sessionstore-backups folder and grabbed a previous.jsonlz4 that has some data but am not sure what to do with it.

Please help! This is a devastating loss of information, as I use my tabs as a to-do list and had many in-progress projects with resources that I cannot all recover just through history.

Recently installed a "cleaner" app called PrivaZer. Ran the app and rebooted as part of the process which also included creating a restore point. Once system rebooted and logged in, pinned tabs were gone?! Using the created restore point did NOT restore the pinned tabs. Is there a way to recover the pinned tabs? Thanks in advance. FRANK

Hi! I wish to edit my limit on how instances firefox runs but i cant. I searched up how to change but cant find the option for it. It said that i should just untick use recommended setting in performance but all that happens is tht i get anotheter option to untick hardware accleration.

Hello! A year or two ago I ran into a problem. While Firefox is checking for an update, it does not load any sites. I have to wait about 5 minutes each time before I can start using the browser. It is incredibly annoying. Has anyone encountered this kind of problem?

I would just like to know why it crashes immediately every time i try to run it, my network isn't blocking it and i still cant run it even after turning off anti virus protection

I have been reading the NYTimes on Firefox for a long time, but it appears that I got logged out without knowing it. I could not log back in even though I used the correct email address and changed my password twice. I can log in on other browsers using my latest password. I called the Times and the person with whom I spoke, after trying to get me logged in, finally said that this is a known problem with Firefox. He did not have any idea about the cause or what I could do; he simply told me to use another browser. I use Firefox for almost everything and this is, to say the least, an inconvenience--for instance, if the Times sends me a link to an article by Thunderbird (which is my email program), I can't read the article but have to find it on another browser. Are you aware of this problem? Do you have any suggestions for how I might log in despite it? Do you know the cause of the problem and whether Mozilla is trying to fix it?

I've hit a crazy problem:

I open firefox and browse to a website. Close Firefox and then reopen and attempt any website and it just hangs. Close the browser and look at task manager and it's still listed - end task open again still no connection to anything. Have tried the Read Only thing in %APPDATA%\Mozilla\Firefox\Profiles\ after a restart of the PC and it stays Read-Only even when I change it. Have tried a new profile which just moves the same behaviour to a new profile ie create a new profile open the browser go to any website, close the browser and reopen and get nothing. I have repaired, uninstalled, reinstalled and I just can't get it to work unless I restart the PC everytime i want to go to a webpage! Anticipate switching to Google Chrome soon if I can't find a solution which is a shame as I have been a Mozy fan for years. Any suggestions?

I'm using Firefox 126.0.1 (64-bit) in Windows 11. I needed to download two files named index.html (in different source directories) from my company's content management system. Both got downloaded as index.htm. They were the right files... only the extension was changed.

I spoke to the person who maintains the content management system. They tested it and said it's not doing that, must be the browser.

That sounds fantastic to me, but I looked through the support messages here and found several about files whose extensions were changed on download; for example from .loa to .mp3. No explanations or workarounds, though.

Can anyone shed light on this?

Hi,

For some time now, when I download a .pptx, .xlsx og .docx Firefox changes the file format to .pdf when downloading the file. I then have to manually choose the correct app for opening the file, overrule error messages and delete the ".pdf" when re-saving the file even though it recognises it is not really a pdf file.

I've tried to change the Firefox settings, clearing cache, restarting or deleting in config and other small attempts to reboot whatever suddenly started to cause this problem. As far as I can see, it is not an unknown issue, but I've not yet been able to find a solution to my problem, which is getting on my nerves.

Hope you can be of help.

I have used Firefox to access my Zoom accoutnfor several years. Today, the screen goes blank when I click on sign-in. This does not happen with other browsers on my PC. Help....

I have had some issues using Firefox and I was told that the website works better with Google Chrome by a support person. For the last recent issue, I was told a website doesn't work correctly basically with Firefox and that I needed to use Google Chrome or Edge. I recently received an email from Mozilla which had a link to an article titled, "Here’s what we’re working on in Firefox" at: link text and in the article in large print it says, "Bringing you the features you’ve been asking for." I didn't see any mention about increasing Firefox's compatibility with websites.

Hopefully, somehow comparability with websites will be made better.

Hi, the site "https://pixabay.com/" is suddently extremely slow with mozilla. The pictures don't showup or take many minutes before you can see them. Normally only white boxes show. The same site (pixabay) with the browser "Opera" works perfectly. I always use mozilla and since a short while it just doesn't work with pixabay (a site for royalty-free images). Can you please fix it? Thanks. Regards Elisabeth

In seeking a way to reduce the CPU & RAM usage, I read that perhaps turning on the Hardware Acceleration might help. And to do that, you must first de-select the default setting which says FF will use the best settings for my computer. Well, when I opened that section, neither one was checked! So, should I first try the default setting, and if that doesn't help, then try HA? I'd always heard not to use HA, for some reason, but I'm ready for trying anything that might help use less resources, and open webpages more consistently.

Which is the best setting to use, or neither one?

There was an update posted today. I ran the update this morning. Now Firefox will not open.

I visted a web site once and left after trying to watch a some movies without any success. Now my firefox are sending notification to my deasktop from this website. But the site is no longer opened in my browser. I tried to to run the antivirus but nothing was found. I checked for any extension and nothing as well. The notification are coming from the firefox itself and I dont know why. And I dont know how to stop it.
