Hello,

OS Windows 10 64 bits Firefox 115.0.7.esr

I have a problem after open my browser with a specific profile and configure the settings about:preferences#privacy, clear history when leaving Firefox is checked, Firefox processes are not completely stopped and cumulate if the operation is replayed.

In the about:config in search fission i have three lines: - "fission.experiment.max-origins.last-disqualified" - "fission.experiment.max-origins.last-qualified" - "fission.experiment.max-origins.qualified"

Could it be the cause?

Thanks for your help.

Whenever I try to watch a video on YouTube, Firefox would automatically set the playback speed to max, mute the audio, and the video would just end (as if someone moved the seek pointer to the end). Since my YouTube is set to automatically play the next video, I would be presented with a screen showing me what the next video would be playing. At this point, I need to do the following:

1. quickly click cancel
2. hit the replay button
3. set the playback speed to anything but normal
4. set playback speed to normal
5. unmute audio
6. move seek pointer back to beginning

From this point on, videos would play normally and I can jump around and watch different videos. But once I close Firefox and restart it, it would reset to the above issues (max playback speed, mute audio, skip first video).

Anyone else having the same problem? Anyone know what's going on?

On a tangent, on my Windows machine, every now and then, Firefox would flash a white blank screen. I would be surfing and reading stuff and all of a sudden, the screen would just go blank. After a few seconds, it would come back. This only happens on my Windows machine and not my Mac.

Hello Mozilla Firefox Community,

I hope you are well. I would like to report an accessibility issue with a website in Mozilla Firefox.

When trying to load https://fafsaprogram.com/ with Mozilla Firefox, the website is currently inaccessible. Despite multiple attempts, the site is unable to open, displaying an error message.

I tested the website on many devices and browsers, and it seems to load without any problems. This issue appears to be unique to Mozilla Firefox, though.

As a participant in the Mozilla Firefox community, I'm looking for help to fix this problem. In my opinion, it is imperative to guarantee that every website can be accessed using Mozilla Firefox in order to offer users a flawless online surfing experience.

Would you kindly look into this and offer any advice or ideas to deal with the issue? Your quick consideration of this matter would be much valued.

I appreciate your help and time.

Warm regards, Alox uilen

So After today update i lost my session, all the tabs gone. All i can do i going through miles of history. No recent closed windows no session restore. Had it on my phone - managed to get one (no option to send all to device, only one by one) but the moment it synced gone there as well, apart the one i sent to device, of course. 127.0 64bit.

Hi, i formatted my pc and upgraded to windows 11 but before that i synced all my bookmarks of previous firefox to my account but after i downloaded firefox on windows 11 and signed in with my account the bookmarks doesn't import automatically but it is asking me to import from other browsers like chrome on which i have different bookmarks and i want my firefox bookmarks back why is it not seemless like google chrome.

Hey,

I constantly have unreadable fonts in Firefox for Mac. This only happens since I started using a new Mac (M2 Chip).

I know there are some "solutions" flagged but I cannot get it to work. My main issue is, the inspector it self has completely garbled fonts. So does the elements of the browser itself, for instance my favorites bar.

I know I am supposed to check my fonts, but I don't know how? I used the fonts application on my mac and let it validate the fonts. No issue there.

Only thing to resolve this issue is to reboot. And this is extremely frustrating since it means out of the blue my Firefox won't show fonts and I have to save all my work and reboot to be able to use it again.

I would highly appreciate a step by step solution on how to fix this. It seems to be a common problem so maybe there is a solutions that describes it better than the text I found here to inspect elements and check fonts.

Thanks in advance.

Hello! I have a serious problem. I lost access to my data because I changed my password, so my data is no longer synchronized. I reinstalled my Windows, and I forgot the old password I had on that Windows. As I reinstalled, I decided to change the password because I didn't remember it, but after that I found out that synchronization doesn't work. Please help me, I had very important bookmarks that were there. Thanks in advance!

Hey everyone,

When I opened firefox this morning, I was notified of the update 127.0 update. I have auto-update enabled. Since the update, my browser experience has reverted back to 1999, where opening a tab is slow to a crawl, scrolling on (for example) facebook is delayed, and youtube videos keep buffering.

Note: I have a beast PC with 36GB RAM, and a 1000W PSU, yet in my task manager it stays as using almost 4GB of RAM and "Very high" power usage.

I've updated drivers, tried the "firefox safe mode" which had the same issues, and confirmed that this doesn't impact any other of my internet-based activities (like gaming and discord).

I've also run a malware check (deep scan) and found nada.

Lastly, I've tried ye-olde 'turn it off and on again'.

Nothing has helped. Any suggestions? I'd love it firefox had a revert update feature but it does not, which is a huge bummer. Please gimme a hand, 'cause I hate Chrome, which is working just fine.

The first post on the Facebook page will always display the timestamp, none of the remaining posts display the timestamp - only a dot or period. The space for the timestamp is there and hovering the mouse over it will show the date and time (so the information is on the page, just not displaying).

I've tried all the CSS fixes, installed the stylus extension, created a userContent.css - essentially everything that seemed to help people a year ago. None of it fixed the problem. I've disabled ALL add-ons - made no difference.

I'm on Windows 7 pro x64, Firefox 115.12.0esr (64-bit). Chrome doesn't have this problem.

As far as I'm aware it started within the last day or two.

Sometimes, when I try loading a webpage that uses WebGL, the WebGL elements won't display and it'll show a black area where the elements would be, and the only way to fix it is to restart Firefox. This doesn't happen all the time, but it happens enough to be super annoying.

How do I get my bookmarks working? I have hundreds of them over the years and now cannot access any of them. I don't know what sync or .squigle is. Please help.

In Firefox 115.8.0esr on linux RHEL7, I am loading a local html page (using file:///...) that I created. Inside the html page, I have a tag "<object id="hiddenDataObj" data="abc.txt">" where abc.txt is a text file in the same directory as the html file. Using my default profile, the data is loaded and some downstream javascript runs as expected. When I use an alternate profile and try to load the exact same page, I get a javacscript error "Uncaught TypeError: hiddenDataObj.contentDocument is null." It is not null when I run my default profile.

I'm trying to figure out what setting in my profile is enabling/disabling the loading of the data so that I can change it. I've gone to about:preferences and scrolled through and it seems like all settings I see are the same between the two profiles.

Thanks for any help.
