Firefox supportforum

Recently YouTube videos have stopped playing when I'm using the Firefox browser on Windows 10. This has occurred both on my laptop and on my desktop computer. The player, surrounding website, comments, description, etc. all load correctly. The video does not, instead displaying either the video's thumbnail and a buffering symbol, or a blank black screen and a buffering symbol. The time codes on the video load correctly. Ads do not play either, and instead after about 15-30 seconds of buffering the "skip ad" button appears in the lower right hand corner of the video. Videos play normally on both Chrome and Edge, and all other media content appears to load correctly (music/spotify, videos on social media websites, etc.)

So far I have tried: - Running Firefox in troubleshoot mode - Refreshing Firefox - Clearing the cache - Disabling and re-enabling hardware acceleration (didn't work either way) - Uninstalling and reinstalling Firefox - Rebooting my machine - Waiting for the problem to fix itself (it's been two weeks on my main desktop/tower and it's still not working).

At this point the only thing I haven't tried is messing with advanced config settings, and I'm avoiding that since I have no idea what any of them actually do (despite what certain reddit threads recommend).

As far as I'm aware, no specific update to either of my machines or Firefox has preceded the issue appearing. It's been going on on my desktop computer for about two weeks, the problem just started on my laptop last night.

It's worth nothing that I usually use UBlock Origin, Simple Tab Groups, and Facebook container. Those extensions are not currently installed since I had to reset my browser in the process of trying to fix the issue.

I can also confirm it's not an internet issue; speed tests show normal download/upload speeds for my wifi, and those have not varied since the issue began. All of my drivers are also currently up to date.

This web site ' cornerstonegrp.securecafe.com/residentservices/carolina-club/userlogin.aspx'. The site tells me that password or pass code incorrect. In the past allowed me to continue to the main web page. At this time all of the add-ons are disabled. Cornerstone web site is the only site not recognizing login. Please help.

After the last update to Firefox on my Mac Book Pro running Mac-OS Monterey, I was offered an update to Ad Block Plus. This add-on, AdBlocker Ultimate shows as installed but it won't run at all and shows as disabled and my existing AdBlock Plus quits working. I'm using Adblock Plus on my windows based computers with all synced together with the Mac Book and the Windows computers are OK, but not the Mac Book. Is there any way to get my Mac Book working correctly? In addition the last update to Firefox on the Mac Book opens by offering me "Life in Color" every time it starts up. How long do I have to tell it I'm not interested? Thanks for your help.

Ok, as it says above, Firefox is randomly shutting itself off, as if you were 'Exit'-ing. I have followed all the aspects of the troubleshooting webpage - so far, when in Troubleshooting Mode, it stays up. I have turned all add-ons, extensions, hardware acceleration...before I went to Troubleshooting Mode...to try and isolate what might be causing it - no luck. I can have as few as 4 tabs open or as much as 10-it still turns off. Now, this does not happen each and every day, but it's close. The last crash report sent in was dated November 11, 4 in total. I have the crash report ID numbers if needed. I can't create the scenario; it's acting as if I am closing the browser, which I am not. This has me lost and frustrated.

Hello,

When my VPN client Private Internet Access drops its connection to the VPN server, all the tabs I have open in Firefox say they have crashed. I can restore the pages by simply refreshing, but it didn't used to be like this. This doesn't happen if I turn off wifi or manually disconnect the VPN, only if the VPN drops the connection. Very strange.

My environment: - Mac Mini M1 2020 8GB RAM, 256GB SSD - MacOS Monterey 12.0.1 - PIA MacOS client 3.1.2 (build 06767) - Firefox 94.0.2 (64-bit) -- ublock origin 1.39.0 -- greasemonkey 4.11

Hopefully you can reproduce and fix it.

When I try to post a pic on Marketplace in Firefox I select the .JPG picture and upload it. The picture I want to post appears fine before I upload it. Once I upload it to Facebook, it just appears as a solid colour. I have attached a couple pics, one is of the pic I want to upload and the other is the pic after it is uploaded. I should state that if I use Chrome or Edge, it works fine. And if I try to post a pic to my timeline it works fine. I just have this problem when using FireFox and trying to post to MarketPlace I know, well just use Chrome or Edge, I DON'T WANT TO :-) I want to use my FireFox. Ian

I was downloading a 3 GB file from Mega. Unfortunately this Mega file hosting web site downloads the file into a temporary location through the browser instead of downloading it like a normal download.

Anyways, while I was downloading, at 54% the download got interrupted saying transfer quota exceeded and I need to wait 4 hours to continue download again. and my girlfriend didn't know this so she thought my download already completed and deleted the file :( After 4 hours of waiting I was unable to continue the download since the file is no longer avaliable anymore :/

Now my question is, where this 1.5 GB file gone? I have already checked %AppData%\Mozilla\Firefox\Profiles\myprofile\storage\default\https+++mega.co.nz but it's not there, the folder size is 102 KB. I checked %AppData%\Mozilla\Firefox\Profiles\myprofile\storage\temporary too but that folder is completely empty. Also checked AppData\Local\Temp as well but it's not there either. The size of my Temp folder is just 10 MB.

While I was searching this, I saw some people saying (if I understood correct) the temporary download location of Mega isn't in hard drive, but in the RAM instead. I want to ask can anyone confirm is this actually true? and if so what happens to that space in RAM when download interrupts like this? Does it delete it from RAM automatically when I close Firefox?

Can anyone with knowledge in this regard please help me with this problem :( I am on SSD and already have a very few space left and I don't want to clutter my SSD with 1.5 GB unusuable file :(( Neither want 1.5 GB space got occupied in my RAM :((

Thank you so very much in advance.

I have long used the option to have a separate address and search bar ("Add search bar in toolbar" in search settings). A few months ago, I changed that to "Use the address bar for search and navigation". The search bar is gone, but when I type a query into my combined address and search bar, I only get "We're having trouble finding this site".

Notes: -) My default search engine is DuckDuckGo, but it doesn't work either when I make Google my default search engine -) I can use the "this time search with..." buttons on bottom, but that's an extra step for every search -) My profile goes way back to the beginnings of Firefox. Any hidden settings that might not have been migrated properly in the past, and that I could check in the about:config?

Hello,

I try to sync with my work computer (windows 10) but nothing is imported. No bookmark, no password, nothing. I do not have any error message it seems.

What information could be useful to resolve this problem ? thank in advance.

I tried to watch Netflix on your browser but got the error message above with a statement along the lines that I needed to install the latest update of firefox.

"It means that the version of Mozilla Firefox you're using on your computer is no longer supported. Follow these steps to fix the problem."

I did update and restarted the browser and later my computer, the same message is appearing.

When I open a new page on a site and the new page includes an ability to comment at the end of the article, Firefox automatically opens at that point. How do I stop this happening? I want the page to open at the top, please - as it always used to.

After years of NO Problems, all of a sudden I am required to re-sign into Microsoft Outlook to sign in. It use to just open and be on my homepage. Using a Mac, firefox 94.0.2...? This use to come up rarely, now it's every time I awaken and sign into computer.

I had a similar problem last year when an auto update came through. After several suggestions didn't help I opted to reinstall a previous version and upgrade that. Now it's back again with the v94 update.

I've disabled ALL extensions. No help. Themes don't seem to make a difference. However, when I went to about:config and entered "toolkit.legacyUserProfileCustomizations.stylesheets" to make it true to allow chrome.css files to work it began immediately. Reset it to false and "X"s are back. Set config to TRUE and it screws up the "X"s. Again, all this is with all extensions off.

I hate the transparency of the tabs and menu bars so I need to set .css files. How else can I do it?

This has happened on several of my computers. Upgrading from some version of FF80 to some version of FF90 results in gibberish text.

What Mac OS system fonts does Firefox require? I somehow got this fixed on one system, but many monthds ago, so I don't know what actually worked. I have cleaned font caches, etc. but cannot get it fixed on the latest so far. Settings are Latin, normal fonts like Georgia or Verdana.

I have done all the recommended solutions including Refreshing Firefox. Youtube still will not run. I just get the pic and the rotating arrow. Have to copy the url and open any other browser and paste. Mac OS vers. 11.6.1 Firefox vers. 94.0.2 64bit

I cannot join any g meet using Firefox browser but i can join using Google Chrome.Whenever I try to to join a meet link it shows "Could not start a video call because of an error."I have tried Troubleshoot Mode and I have even tried to reinstall Firefox but the same thing.I would be great if someone can find me a solution thank u.

Opening up firefox last week am a message saying something was wrong/couldn't proceed (I don't remember the exact text). I tried to delete the message, but it just came back every time blocking opening firefox. I tried to restart it, but the same blocking message reappeared. I then uninstalled it and all my files disappeared, of course. I've today reinstalled it, but no history, etc.. How can I get my original web files back? Do you have a 30 day grace period where any file can be restored like the one Microsoft has? Can I get my webfiles back at all? Please help. tmr W10 64bit

Hello，somebody。 My firefox browser has collapsed 8 times from 2021/12/1. It is currently operating normally, but the number of collapse is too frequent, and the user experience is very poor. The latest Crash report ID：bp-fd4c7367-1346-4a10-a2cd-244ac0211202
