FF is offering up possible login names for a particular site I have used previously even though I have removed all related browsing history, form data, and cookies (and cleared the cache). What am I missing? Is it using stored history for unrelated sites to guess at a user name, or is there some other hidden history I need to clear?

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.

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?

When I try to log into Tangerine bank I get the error. "We're sorry for the inconvenience. This function is currently unavailable. Please try again later."

This issue started Oct-13-2025 and it appears to work when using Firefox ESR 146.01 but not the regular Firefox 146.01 versions. Tangerine is not giving me information on the error and I was wondering if there is a difference between the ESR and regular version that might clear up this issue?

I get the message: We're Sorry Firfox had a problem and crashed. We'll try to restore your tabs and windows. To help us diagnose and fix this problem, you can send us a crash report. I sent the crash report multiple times.

I added a screenshot of my MacBook Air info.

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?

Not sure if "browse" is the correct topic but here we go:

After a random crash (I don't remember the details, been a while) I've "refreshed" Firefox. Following that I started to have some problems with Google Meet. Haven't had any for years and suddenly when i open Google Meet (working from home and using Google Meet as an online meeting platform daily), everything becomes unresponsive. I can't change tab, cannot close Firefox from the close button, nothing. I open the Windows Task Manager and End Task manually to close the window so I can restart the browser. After restarting Firefox and launch Google Meet, it doesn't crash.

The other problem is when I try to watch something on Netflix, I hear the sound, see the subtitles but the video content is not present. It's just black screen with UI on it. Yes, I checked the DRM setting and no, other streaming services that I use don't have this problem. I can bypass this by launching Firefox in troubleshoot mode but I want to use my extensions. I even tried to enable them one-by-one to see if anyone causing problems but even when I disable all of my extensions like in the troubleshoot mode I'm still having the same problem.

I tried several solutions that I found on reddit etc. but nothing worked so far. I also re-installed Firefox and nothing changed.

Please help me before I lose my mind (:

Running Firefox 140.8.0esr (64-bit) on Windows 10 Pro on an HP laptop. The feature/problem described works properly with Chrome and Edge. The problem occurs when accessing the following article:

  https://www.comsoc.org/publications/ctn/turning-fiber-sensing-system-magic-fiber-optics-sensing

If the window is set wide enough, there is a sidebar displaying, "Share this content in X". If the screen is squeezed down (i.e. drag the right margin to the left) far enough, the sidebar will disappear. That feature is handled properly, but as the window width is increased and the sidebar appears, the main body of text does not wrap properly. It appears that Firefox is not compensating for the width of the sidebar.

 NOTE: As I am not a HTML expert, my subject line referencing a particular HTML class could be misleading.

Firefox will only start if I sign in as an administrator. It doesn't connect to the internet, and I can't get to the help screen. I did a refresh but that hasn't help. If I uninstall and then reinstall a new copy correct the problem? How do I save and reinstall my bookmarks and settings? I love Firefox and prefer it over other browsers. But I need to fix it and any help you provide will be very much appreciated. Thank you!

Firefox not responding. I have tried everything on the Help pages. I have tried reset of everything. I have uninstalled and reinstalled from scratch. Still: when I open it: Firefox does not respond. And everything else also is very slow then. In Windows joblist I can see Firefox with 7-15 threads. One of them "not responding". I have no problems with Chrome nor Edge - W11, 16GB Ram

Ce matin,09/03, ORANGE a mis en place une nouvelle messagerie qui ne passe plus sur FIREFOX mais que j'ai retrouvée par un autre navigateur. Tous mes contacts avaient disparu ainsi que les messages reçus ou envoyés.

The recent update changed how the mute button works in Firefox, before it would replace the icon and would show text and whatnot if it was muted or wanted to autoplay; now it just always shows the mute/unmute button in a tab playing audio. This would normally be fine but it is causing my tabs to constantly be shrinking and expanding whenever the audio changes in a tab, and it's really frustrating me and it feels like an overall far worse user interface design than it was before, even if people were complaining about it. Is there some sort of middle ground where I can set a maximum tab size or something? I know this used to be a feature in about:config but it doesn't exist anymore for some reason. I've also tried using a userChrome CSS code for it that I found online; it got rid of the button but it still made the tab size change and the code I tried using for maximum tab size also didn't affect that. Really starting to frustrate me! Please give me any advice I feel like I've exhausted all my options lol

Since I upgraded to you, I am having trouble accessing important and medical info. I would like you to put every thing the way it was before. Easy access. You erraced some of my passwords, I want them back. I spend hours trying to find my info. I am 80 yrs old and do not need this aggravation. Thank you Moira

A user I am servicing uses Firefox every day. They are on Windows 11. Every afternoon (sometimes at other times), Firefox stops working and loses its internet connection (everything else on their computer continues to be connected).  When they close and restart Firefox to reconnect, it then tells me the user that they are using an old profile and need to create a new one.  They're able to re-log into their Firefox account, which eventually resyncs all their data, but they then have to re-sign into everything, which is a major inconvenience.  The only workaround the I have found is to reinstall Firefox, ever time this happens which then allows the user to use all their settings until they have to repeat the process the next day (i.e., everything remains signed in and/or logging back in is easier than described above).
