with this new version i lost everything i need to get back to an older version and get all my extentions my bookmarks back all my s desktop items that i had linked to firefox are gone i can no longer get face book or anything back to firefox book marks every thing i had with firefox

and

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?

Hi,

I use Firefox app in macos, android and ipados. The bookmarks across them are not synching automatically. I need to press sync manuelly to do. All apps are updated, all settings look fine. Please help me synch bookmarks across platforms. Thanks a lot.

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.

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 ?

If it ain't broke, don't fi(o)x it. Never try to be too clever. I cannot log out of OUTLOOK.COM, then after goodness knows hot long, it says that I have been kicked out and need to login again. CRAP!!!!!!!

Lost my Passwords on my desktop and can't recover them through profile manager, I found them on my android phone and want to recover my passwords from there, but am worried if I try and sync to the desktop, the desktop might overwrite the passwords in the phone.

Ok, This is a bit of a question that seems to have many answers but none that have ever worked for me. I have in the past 12 months probably formatted my PC 4 times, and I have at least 12 profiles on Firefox nightly, not to mention the rest of the family. It's not really a problem to redo them every time, but it is just a painstaking simple process. If I could just backup the profile folder, copy it move it change it whatever, it would be nice and simple, even to transfer from one pc to another in the house, but every time I try, It fails. Copy the Userdata folder, copy the entire firefox folder, blah blah blah, never can I do it. I believe it has something to do with security that you can't just copy and the entire profile folder, but some way to backup the profiles exists surely? One that actually works. Cheers All!

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.

Hi, I opened Firefox to continue with my work, just to get greeted with a 'start a new profile' page. All my profiles, saved data, history, add-ons and customization, were discconected/removed. Even on my phone it logged me out from my account- logging back in doesnt retrieve my history from my previous sessions on my desktop device.

I tried logging in to my account, checking if theres an 'old firefox' folder on my device or anything like that, but it did not retrieve any of my old data.

Just to clarify, I have not played around with my settings, left or deleted anything, so I really dont understand why I've just came back to nothing.

Was wondering why this happened, how do I know this won't happen in the future, and if, when possible, how can i get all my data back?

Thanks

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 (:

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!

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

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).
