Hello, when I change layout.frame_rate in about:config from -1 to 900 it works perfectly for 30 seconds and then every single time after 30 seconds it drops to 92 - 95 and stays stuck within that range. When my friend tried the same thing with their cap set to 400 the same thing happened. It's not a CPU or GPU issue as when I set it to uncapped in firefox and other browsers it can stay very high indefinitely.

Can anyone help me stopping it from dropping like that? Thanks!

Running firefox 121 with Gnome I was hoping a problem that existed with earlier versions would be resolved. When the window protocol is wayland and the window is fullscreen (F11), playing video fullscreen causes the image to be "oversize" and only the upper-left quarter is shown.

Doing the same thing with window protocol of xwayland results in fullscreen video displaying properly.

I believe this is due to an issue with the way my 4k screen with 2x UI scaling is being reported to Firefox:

Under xwayland, I get the following information for my display (Display0) 3840x2160@120Hz scales:1.000000|2.000000

When running wayland, I get 7680x4320@120Hz scales:2.000000|2.000000

Thanks in advance

Over the past few days Firefox had been randomly slowing down, and sometimes wouldn't let me click back into it from certain tabs in the foreground. Earlier today it blue screened my laptop. I have never experienced any kind of bluescreens before. Event ID was listed as 2. I was not attempting to open a new tab or had any abnormal tabs open, I was simply clicking back into the browser from another application. The application was the Fortnite launcher, which I doubt would have created serious conflicts with Firefox. Attached to this report is a screenshot of the event on my laptop. My laptop is an OMEN HP gaming laptop. It has an i7 12700H and an RTX 3060 (Laptops). It has 952 gigabytes of storage, 418 used. It has 16 gigabytes of ram. The only applications opened at the time were discord and steam. It is now running fine with no files lost, however I'm reporting this at it may be a deeper issue with Firefox itself as I don't presume I was taking any actions that would have resulted in a blue screen. I don't necessarily need help but this was the only avenue I found to submit a bug report. Apologies if this is clutter to the site and not the proper avenue for this sort of issue. However I felt it was important to report any form of bluescreens as those are rather severe issues.

Hi I need to run multiple firefox instances, each with a dedicated profile The following used to work before version 121 on MacOS: /Applications/Firefox.app/Contents/MacOS/firefox-bin -no-remote -p &

The above method is not perfect, but it works. Since Firefox upgraded to 121, the above method stopped working.

Any way to launch multiple instances as before? Hate to switch to Chrome, but Chrome allow you to switch easily.

Hi,

My Mozilla Firework crashed and I can't open it at all. I have really important information there that I need access to ASAP. Everything is lost and I can't access it.

I have some sort of cloud next to the Mozilla Icon and I have no idea what it means.

Please, respond as soon as you see, as I really need your support/help regarding this matter.

I can't believe that all documents can be lost just like that.

Thank you.

Been using Firefox for a very long time. I'm currently using windows 11 with Firefox 121.0.1.

I have always used the hibernate function to switch off my computer when I finish a session, and up until a few months ago Firefox would spring back to life once my desktop reloaded.

Then I started getting this problem ... Firefox is most often but not always terminally slow to reconnect to the internet (other apps and functions have no issue). I have found the simplest way to overcome this is to shut down Firefox from Task Manager and restart it - it then connects in seconds. I suspect this started after an automatic windows update, but can't be certain.

I have searched google and Mozilla sites frequently for help with this issue but haven't found others posting the same issue as me. I think it is connected to windows power management and have checked but can't find any obvious windows setting that could cause this and have also tried switching off Hardware Acceleration but that makes no difference. Can anyone help, please? Thanks

windows update.

Hello, first of all thanks for reading.

I started using Firefox recently because I was experiencing frequent crashes using Microsoft Edge, usually when watching streaming video. I was also experiencing occasional BSODs (Blue Screen of Death). A lot of my troubleshooting searches suggested RAM was the issue, so I did memory tests, none which detected anything abnormal.

For good measure, I also did a clean reinstall of Windows. Strangely, Firefox didn't crash at all from an entire day of YouTube yesterday, but today I got 3 crashes in a very short amount of time, which you can see linked above (I don't have any more crashes). Even stranger, one of the crashes occurred when I was just browsing the Mozilla Support pages.

Anyway, I didn't read too deeply into them, but it looks like they're all citing my GPU driver as the issue... is that correct? Thanks for any ideas.

Since last week, any Google search I make using Firefox is diverted to MS Bing, the screen refreshes itself several times before settling, and then the links given in the response do not work. I have run a malware check using my Avast antivirus software which has come back clear.

I have tried checking 'Add-ons and themes' in Firefox, but only see a blank page with the identifier 'about:addons'.

Searches using Google Chrome are fine.

Can you advise please?

CORS issue only on Firefox browser

Dear Mozilla Support Team,

I hope this message finds you well. I am reaching out to report an issue related to Cross-Origin Resource Sharing (CORS) in the Firefox browser.

When attempting to logout from my Java Spring application, I encounter the following error message: "Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at (Reason: CORS header ‘Access-Control-Allow-Origin’ does not match)." This issue seems to be specific to the Firefox browser, as I am not experiencing the same problem in other browsers.

I have thoroughly checked my web application's code and configurations, and the issue appears to be related to how Firefox handles CORS headers. The server is configured to include the necessary "Access-Control-Allow-Origin" header, and the application works as expected on other browsers.

Steps to reproduce the issue:

Login to the application in Firefox. Click on logout in Firefox. Observe the "Cross-Origin Request Blocked" error in the browser console. (Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://login.mydomain.com/logout. (Reason: CORS header ‘Access-Control-Allow-Origin’ does not match ‘https://login.mydomain.com’).

Expected behavior: The remote resource should be accessible without CORS-related errors.

I would greatly appreciate your assistance in resolving this matter. If there are any specific settings or configurations that need to be adjusted in Firefox to address CORS-related issues, please provide guidance on how to do so.

Thank you for your time and attention to this matter. I look forward to your prompt assistance in resolving this issue.

Best regards,

Hi everyone i'm a way way older firefox user since i don't remember. I never had any big issue with it, but since i moved to my new pc few days ago, i noticed some issues that i can't solve.

Let me explain:

I've installed firefox on C: (SSD) but moved, as i always did, the user profile to F: (HDD) but i noticed few problems (i already tried few solution i knew and that i found on internet but no luck at all):

1) [IMAGE 1] In the start menu, firefox is shown without the icon

2) [IMAGE 2-3] if i visit a page and then i visit (for example) a product page of the same website and i save that product page on the bookmarks, that page will not show the favicon until i visit it a second time

3) [IMAGE 4-5] if i save a page on the hard drive like a shortcut, most of the page will show the proper favicon in high quality, others will show a low quality firefox icon (this happens also with different pages from the same website), one will show the proper icon, then other one no (i noticed inside the profile folder that inside the folder called shortcutCache the page with the right favicon saved have the right icon there too, the wrong one is wrong there too).


Any idea on how to solve this issues? Are those linked to the latest version of Firefox? I already tried to uninstall it, reinstall it and other solution that i found on the internet without any luck as already said.

Thanks in advance to anyone who will try to help me Cris

Don't know if i was clear or not, but those simple issue are driving me mad since i have a lot of bookmarks and a lot of shortcuts
