YouTube all of a sudden started to slow down and only be able to load videos fast enough in 360p resolution, I tried watching YouTube on Microsoft edge and YouTube handled 1080p easily there, I have cleared the cash and made sure my Firefox and Windows are up to date and still the issue persists.

this only seams to occur on YouTube as amazon prime and speed test works without issues

When I try to play a video on Firefox desktop, it takes it a long time to load. Once it has loaded, whenever I pause it for more than a few seconds, or if I try to skip around the video (either by clicking around in the loaded section of the progress bar or using +/- seconds buttons), the video begins buffering again before the video resumes. This makes it extremely difficult and frustrating to watch anything that requires me to pause, rewind, or fast forward. I've noticed this issue affect multiple video viewing sites, such as YouTube, Vimeo, and Netflix. My roommate also uses Firefox, but doesn't have this issue, so I know it's not a problem with my internet. I thought it might be a problem with my computer, but I tried to replicate the issue in Chrome and everything worked fine there. The issue has persisted almost a week. I have:

  • Rebooted my computer several times
  • Deleted my history/cache
  • Disabled my extensions
  • Turned off Java scripts in firefox (this disabled my ability to load sites like YouTube completely, so I turned it back on)
  • Updated my computer
  • Updated my graphics drivers
  • Refreshed firefox
  • Uninstalled and reinstalled firefox (and rebooted my computer)
  • Uninstalled and reinstalled firefox AND deleted all the data it stored on my computer (and rebooted my computer)

I am currently using version 123.0.1 of Firefox. My OS is Windows 10 22H2.

I have a very good PC (5800X3D, 7900XT, 32GB DDR4 3600), but Firefox (either the normal, canary and nightly version) can't play smoothly any 4K video (like the Borderlands trailer: https://www.youtube.com/watch?v=lU_NKNZljoQ ). 1440 and lower resolutions are fine, as are 4K videos on Chrome and Edge. FWIW, my CPU during 4K playback is barely used (1-2%), and my GPU's video codec (VCE) is used by around a third. Disabling HW accel makes things better, as it still stutters but it's (barely) passable. I already tried creating a new profile, but still it's the same.

The icon for private browsing has recently re-appeared on my taskbar despite having browser.privateWindowSeparation.enabled set to false in about:config.

I've had this setting configured ever since the update which completely changed the appearance/behavior or private browsing and it has worked correctly up until today (14/06/24).

Is there a new setting that I have to adjust in order to "merge" the windows together as I'm not a fan of having the private browsing icon on my taskbar.

Hi, I've upgraded to Windows 11 today and couldn't open Firefox since. Things I've already tried:

  • Reinstall Firefox and delete all old files (Appdata & Program files)
  • sfc /scannow and DISM.exe /Online /Cleanup-image /Restorehealth
  • Windows compatibilty mode
  • Firefox Troubleshoot mode won't open either
  • ipconfig /release & /flushdns & /renew
  • netsh int ip reset & netsh winsock reset

When opening Firefox in any way, i get a white window/just the window border which immediatly closes. When trying to start troubleshoot mode, the small window has the same issue.

I also checked the crashlogs and none were generated. The Windows event-logger also has no entries.

BTW: Here is a video of whats happening: https://youtu.be/AJP4rqZFxlY

There used to be an extension called "IE Tab". It allowed you to right click on the link, and open the site in a tab, using Internet Explorer, for sites that didn't work properly in Firefox. I was wondering if anybody knows of any similar extension that would do the same for Edge? I can't open Twitter (X) using Firefox anymore, but I can open it using Edge. I don't like Edge (obviously), but I have no choice. Thanks in advance!!!

I upgraded from 126.0.1 to 127 today. Upon update, all my windows are gone. The only way I could access them is to revert to an older profile backup and reinstall 126.0.1.

I tried exporting my session with Tab Session Manager in 126.0.1 and reopen them in 127, but that only restores the last tab of each window (oddly). The json clearly lists 3 windows each with multiple tabs. I tried copying the sessionstore-backups folder, but no dice.

Recaptcha isn't working in Firefox. It works in Chrome, Opera, and Edge with no issues, it will either just go to a check mark or open the window with the pictures to choose, on both regular pages and on the Google Recaptcha Demo site Google Recaptcha Demo site. But when I load a page that requires Recaptcha in Firefox, it just spins forever. It was working fine a few hours ago, and I didn't change any settings or anything in Firefox. I was filling out a job application and it worked fine, then I went to another job application and Recaptcha won't work at all, even on the Recaptcha Demo site.

I'm on version 125.0.3 (64-bit), on Windows 10. Not using a VPN or anything like that, just a standard Ethernet connection, with whatever Charter gives me.

Steps I've tried, none of which have helped:

1. Cleared Cookies. 2. Restart Browser. 3. Restart Computer. 4. Restart Modem and Router. 5. Opening Firefox in troubleshooting mode. 6. Ensured Firefox was up to date. 7. Reinstalling Firefox. 8. Turned Connection Settings to no proxy. 9. Turned off Enhanced Tracking Protection. (It's set on standard otherwise, and I didn't change it) 10. Release/Renew IP via Command Prompt.

I'm genuinely at a loss of what to do, after a couple of hours of searching around for solutions. I don't get how it just stopped working in the span of like ten minutes when I didn't change any settings or anything. Firefox is my main browser and it would be a tremendous pain to have to use another browser for any pages that require Recaptcha.

Any assistance or advice to solve this problem would be greatly appreciated!

I have an add-on ad blocker for youtube and have never gotten ads. This afternoon that stopped. I get ads with every video I click and there is no 'skip ad' on the screen. I added another top rated youtube add blocker, quit firefox and then opened it again. Before, if I clicked a video it started an ad and I could go back and then hit the video again, but now that doesn't work, but if I select to show the video in a new tab, there are no ads in that tab. What can I do to make the ads stop like they used to and never appear? Yes and my OS is Ubuntu 22.04

My Firefox Browser on (Windows 11) updated on 23rd March 2024. Now my History and Bookmarks have been deleted (but not cookies for some reason). yes, it is my correct profile as I checked the dates and also double checked it against a backup I made 2 weeks ago.

Have included an image of my 'more troubleshooting information' details - I'm sure this is supposed to have more data on the page?

If there is no way to recover my hisotry and bookmarks, I see there in my profile folder is a 'bookmarksbackup' folder which contains .jsonlz4 files, one of which was saved on the 21st March 2024. I know book marks are .json files, can anyone tell me how to turn a .jsonlz4 file to a .json?

[Oh, I pressed to add here my 'troubleshooting information' as directed by this forum page and it said it couldn't automatically do it, and when I pressed 'manual', it opened that over this page and so when I pressed 'back' it had naturally deleted this post so I've had to retype everything from memory, thanks so much Mozilla for that. How about a warning that this will happen?]

I have been experiencing a problem with Cloudflare specifically on one site (character.ai) and when the verify you are human pops up. It takes me in a seemingly infinite loop. On the Cloudflare community site they say it could be because of things like adblock but even without any adblock or anything of the sort on it does the same thing. Sadly Cloudflare community doesn't support being used on Firefox. So maybe they don't support being used on Firefox in general? I have contacted the actual websites support but they don't seem to even read submitted inquiries because I never hear anything back from them except the automated message they received it. It is now preventing me from using certain things in general which as before it wasn't that big of a deal but recently they changed the site layout and still allowed you to use the old layout but the verification blocks you from using the old layout. The first one is one from a couple of weeks ago when it only effected me trying to open things in a separate tab and the second one is the newer one which prevents me from accessing the old layout. I'm not sure what to do about it since nothing I specifically could do to solve it has helped. I have opted into sharing data under troubleshooting IDK how well that'll help.

I have an issue with Firefox 127 not accepting a session cookie that I use for user authentication. I have an ASP.NET application with a login form that includes fields for login and password, and a submit button. When the button is clicked, an HTTPS/POST request is sent to the server. The server responds and sends back a session cookie named .Cookie.Name with the parameter httpOnly set to true.

When I check in Firefox's Developer Tools under the Network tab, I can see .Cookie.Name in the server response. However, in the Developer Tools under the Storage tab, .Cookie.Name is missing, which prevents the user from logging in. This problem does not occur in other browsers like Chrome or Edge, nor does it occur in Firefox version 126. The configurations for Firefox 126 and 127 are identical.

Could you please assist with this issue?

Hi. I am running a 3 monitor setup and I like to keep open quite a few tabs. And two windows of Firefox. So two Firefox instances with several tabs on each. But because it eats a lot of memory, I have to close and reopen Firefox from time to time. And to my annoyance, sometimes it "forgets" about one of the windows. So opens only one instead of both. Therefore I loose some quite important tabs. Any suggestions on how to fix this? Thank you.
