It looks like my firefox profile got corrupted during a power outage is there a way to repair it or at the very least get back my opened tabs? I had lot of them and it will take a long time to find them all again...

The profile in the image i cannot open anymore:

After clearing Browsing data, therefore Loging out of twitch etc., i now constantly get the error "Browser not supported" on attempted login

Other Browsers (Chrome) work fine and ive already tried deleting Extensions and reinstalling the Browser to no avail

here's the error messages that come up

any help would be appreciated

The sound works for me on Opera (PC Win11), but not on Mozilla - I see it as a bug in the browser... even after clicking on the playback device in the bottom right corner in Mozilla, the sound doesn't start playing...

Firefox is causing my wifi adapter to shut down

Running firefox for any length of time will shut down my wifi adapter at a random moment. The only solution is reboot

Using opera, the problem does not occur, I can run opera continuously without problem. Running firefox at anytime will cause the fail at some point.

Im running windows 11 I have run firefox in safe mode Disabled all addons Set to “No Proxy” Disabled power saving on the adapter Replaced firefox with the ESR version 140.8 , previous version was the latest I note that there are up to 11 firefox process instances in task manager (all cleared when firefox is shut down) Firefox is set to update automatically Several updates have occured during this problem Disabled hardware acceleration Cleared cache Latest wifi driver And a few more that I cant recollect at the moment

Running out of hair to pull out

Any idea’s?

I rarely turn my laptop off, when I'm not using it I put it into sleep mode. Firefox absolutely hates this though, and after a few days it will slow to a torturous crawl. Everything becomes horribly irresponsive, feels like nails on a chalkboard. It can even get to the point where it will randomly delay my cursor in Windows 10 itself by 10 SECONDS along with some bleed into other programs while switching between them. Fully closing Firefox then re-opening it will reset the issue, starting the timer again, but I hate doing this because I have doing that set to log me out of various sites which I then have to re login to, letting the torture boil until I give in. This has been my Firefox experience on laptop for at least 5 years now. Other forks of Firefox have this same issue.

I am leaving Firefox in the torture state currently to troubleshoot here. Currently the memory usage on Firefox is 6GB at 54% of my total ram, which is being used at 84% total. Total CPU usage is 23%. Wrote this on my desktop for my sanity so that's why there's no troubleshooting information.

For the last 2-3 day I have been experiencing a box that asks for my signature each time I go to a new website. I can't move the box. I can't screenshot it. Does anyone know how I can get rid of it?

After i installed firefox net jitter somehow appeared in my cs2. every time i play jitter is jumping randomly. Can yall somehow fix this i really enjoy using this browser but i just cant play with it running in the background((((

I had about 15 pinned tabs - unloaded - that I was saving for a research project. I shut my PC down and when powered up for the next session - all the pinned tabs were gone. I never thought to record the tabs via screen shot or something.

Is this normal - what are the limits of pinned tabs ? Do they expire in a day ? When the PC powers down ? When Firefox updates ?

Exactly what are the limits or boundaries for pinned tabs ?

I'm running Linux devuan: Linux MikesPI 6.1.93 #1 SMP PREEMPT Mon Dec 8 02:37:53 CET 2025 aarch64 GNU/Linux and Firefox 140.4.0esr (aarch64).

For years now I've been downloading and saving Yahoo quotes as csv, now for the last week Firefox wants to save page image poping up an extra window that must be refused before I can continue using Firefox. Hopefully someone can tell me what new option in about:config can be turned off to stop this. Thanks, Mike

Hello Folks, I just importeda a new certificate. Then I wanted to save all my certificates for backup. Selecting "Backup all...", I neter a secure password and click ok just to get the following error message: Failed to create the PKCS #12 backup file for unknown reasons the only button is "OK"

How can I start finding out what is going on and is there any means to save my certificates?

A few weeks ago, I started to get repeated messages from Firefox asking me to make Firefox my default browser. Firefox has been my default browser for years, and I have never made anything else my default browser. Anyway, I followed the prompts and re-selected Firefox as my default browser. A little while would go by (sometimes as little as a minute) and I would again get the prompts to select Firefox as my default browser. This append 20 or 30 times. And, every time it happened, all of my saved passwords disappeared, but would reappear when I re-selected Firefox. In the last week, this situation has gotten a lot worse. Now, the saved passwords don't come back. And, the prompt you usually get when entering passwords to a new site offering to save the password doesn't appear any more. So, the only way I can rebuild my saved passwords is to enter them manually, which I am not going to do because it would take a couple of hours and then I'm pretty sure they would all disappear again. Also, I like to go to my homepage when I open a new tab. Can't do that anymore. When I open a new tab, I get a new private browsing window. I have checked all my settings a dozen times, and they are correct. I have combed your support sites and there is nothing there to help me. I don't want to dump Firefox, but I cannot continue with it behaving as it does now. Is there anyone anywhere in your organization who can help me? Thank you.

What is wrong with firefox! It doesn't work right with benzworld.org a mercedes forum. Page becomes unresponsive, or when clicking a link for a thread it takes incorrect page. Other browsers don't have this problem. Saving a bookmark, it doesn't save. Uninstall, reinstall, same thing.

Firefox autofilling my freaking CC number though those settings are disabled. I want to know what Firefox file my CC number is stored in.

Give me the filename -- I'll do the rest...

It is with deep regret to inform you of my discontinuation of the use of Firefox.

My issues began at the beginning of February this year and have continued and compounded to the point that I cannot continue its use. The issues are constantly logging me out of my account, disabling ALL my bookmarks and the loss of well over a hundred passwords. I have followed every help article and community forums help links and to no avail I'm still dealing with all the same issues. I've have to restore my links every time I'm logged out of Mozilla. Their are no passwords to restore except for the Mozilla account I just had to log back into.

Again, I do regret discontinuing its use. I have used this browser for well over a decade and I am not one for changing anything at this point in my life. I'm 67 and having to switch is indescribably painful. I actually think your integration of AI functions are the problem. Everything was just fine before that was introduced.

If you have any comments, please feel free to email me at my former account email address.

Farewell old friend.....

I already have Firefox on my laptop and via Mozilla I was asked again to install Firefox. Furthermore I always got the question that I should use it as standard browser. I have no idea what else should I do in that case. If I would install again Firefox, I will lose all the paid apps which run already on the current version. So I am really very confused about the characteristics of this Firefox installation and the strange requests by Mozilla to install Firefox.

I would be delighted if you could me support with checks to find out about the nature of the current Firefox installation or a simple de- and reinstallation instruction of Firefox (and keeping the paid apps like Ad Blocker...).

Thank you in advance for your feedback
