Firefox Community Forum

Hi

I've just booted my machine and opened Firefox, only to be presented with a completely fresh install.

All my settings, bookmarks and history gone. It was fine yesterday when I closed it and powered down.

I'm running Kubuntu, I've checked the .mozilla folder and nothing...it's like my profile has just been overwritten.

Not happy at all, I'm starting to dislike Firefox.

Can anyone offer any help or advice please?

Thanks in advance.

I'm trying to install Firefox on my work computer (ARM64 version), but when I do I'm getting the crash report window at the end of the installation process (multiple times in a row), if I try to open the browser (only once), and during the uninstallation process (also multiple times in a row). I've tried a clean reinstall multiple times, including deleting the folders from program files, %APPDATA%, and all registry entries I could find (HKEY_CURRENT_USER>>SOFTWARE, HKEY_LOCAL_MACHINE>>SOFTWARE, HKEY_LOCAL_MACHINE>>SOFTWARE>>WOW6432Node).

I've contacted IT and they don't seem to think anything pre-installed should be affecting this. I'm unable to get a crash ID as I'm unable to even start the browser - all I get is the Firefox crash reporter, immediately. Is someone able to help me figure out why I can't get this working?

Hi,

I have tried to sync between my two computers, but it did not work out well:

e.g when I click on ‘show more bookmarks (>>)’ on the right side of the screen (next to Other Bookmarks) I get - Firefox is not responding and I have to click on

-> Close the program.

If I click on -> Wait for the program to respond - Firefox never responds! And before I click on -> Close the Program - my keyboard input is totally erratic!

This occurs on both computers! - what can I do…..

I have therefor on the computer I want to be on the receiving end:

- deleted: History, Downloads and Tags and All Bookmarks - Cleared browsing data and cookies - Closed all open tabs

And now I am Signed in with Syncing; ON - on both computers again.

But I have not checked any of the check-boxes in ‘Manage sync…’ - ‘Manage what syncs on all your connected devices’ i.e. Bookmarks, Passwords, settings, History, Payment methods, Open tabs, Add-ons

Why is there no check-box tag groups!

What do I have to do on my SOURCE compute and on the DESTINATION computer for - a one way sync of everything?

Best regards, Einar

PS,

After Signing in I was presented with the following, and I chose Not Now

Sync your Firefox experience View your saved passwords, tabs, browsing history and more — across all your devices. Select an option to continue:

- I already have Firefox for mobile Start your sync now if you already have Firefox on your mobile device. 

- I don’t have Firefox for mobile Download Firefox on your mobile device, then start your sync.

Not now

How to disable the Enterprise Roots preference-have tried everything I can find on this issue. In summary, deleting certificate via reg edit but this does not work, have to delete certificate every time I re start windows 11 desk top pc.

Any other advice? Thanks

After firefox update, start page changed to first photo i added here, second photo is how it was before, is there any way to get it back? Before update i had version 131.0b9, now its 136.0b1

bookmarks toolbar not showing items in linux firefox 139.0.1 - it broke in this update. All it shows is text reading: "For Quick Access, place yada yada..." I tried adding it back, it's broken.

Gmail is slower than frozen molasses, it is taking 15 to 20 seconds to respond to mouse clicks and typing as well as scrolling, it takes me more than half an hour to do what should take a few minutes, if this is not fixed soon that will be the end of Firefox for me, I will use Opera instead.

Hi i have lost my bookmarks, comes up Import bookmarks, my sync is on, I have gone through and checked library and there are no backups, restore? No idea why this happened, they all just disappeared? Any other advice to try please?

Secure Connection Failed An error occurred during a connection to (Firefox and ALL sites) PR_CONNECT_RESET_ERROR Error code: PR_CONNECT_RESET_ERROR Help advises 'Failed to check for updates' Problem arose on upgrade to Firefox 138 Tried restart, computer reboot and reinstallation

I am not sufficiently computer literate to understand supposed help and support documents within 'Mozilla Support'

It looks like the end of 20 years of using Firefox ... Google Chrome used to submit this request

There are many sites where I am unable to log in. One of these three things usually happens. 1. Fill out email and password, click log in, infinite loading with on some sites (like Spotify) an error about not being able to load. 2. Fill out email and password or the form, try to click send/continue/log in but I can not click it, it's greyed out. 3. Fill out email and password, get told it is incorrect. For any of these issues, if I switch to chrome (which I am trying to avoid) it works, it's just limited to Firefox.

I have tried disabling the advanced protection, that doesn't change anything. Any tips would be much appreciated and I will try to answer any questions as fast as possible.

Thanks in advance

Historically, I remember when you open the `sync` sidebar and right click on the tab grouping (i.e. Firefox on iPad), it opened a context menu where you had the option to `open all synced tabs`. This seems to be missing from the latest version of Firefox (138), but wanted to check in to see if I'm missing something or if I should downgrade my version of Firefox to get that functionality again.

I have a strange problem and cannot find any reason for it.

On two different machines (with the same Firefox account, same extensions) I'm using tab groups, also in multiple windows (restoring them after launching Firefox).

In one installation I can close all tab groups without any problem.

In the other if it's the last open group, trying to close it (by clicking its header) opens a new, empty tab instead.

I'm pretty sure the settings of both installations differ but I cannot find any setting that would cause this behavior. It's especially annoying because with many open tabs I have to scroll through all to find the group I want to open instead, open it, scroll back to the other group header and close it.

Any pointers on where to start looking?

Hello all, I have the same exact problem described in post https://support.mozilla.org/en-US/questions/1463436, dated 9 December 2024. Until ten days ago (more or less) all was working correctly. At the beginning I thought there was a problem with Intesa because Intesa had problems in all the country in that period, but I have now tried CHROME and found that is working correctly. My system uses Firefox 139.0.1, W10-32 and Iliad FTTH. I have already cleaned cache and data from settings but the problem remains. Any thought? Thanks very much for any help. Mario.

Hi, I hope maybe there might be a ray of hope here but I royally screwed up. Like BIG time. I was having issues with my windows laptop & the microsoft guy said to do a factory reset but select the option to keep my files & everything will be fine. Which I did. I did the reset & logged into my Firefox, only to find that NONE of my passwards had saved. It had asked for a 32 Key code but I've had this account for years & years & years and have never once been given a 32 key code. I thought maybe it was an option for future password reset so just clicked on 'next'. Well my bad, that was the dumbest thing I've ever done because all my passwords have been wiped & I've only managed to recover a tiny handful but most of them seem to be gone for good. Is there any hope of recovering? I thought because I had a Firefox account then that would be that, everything would be saved in the that account. Really wish I knew about the code thing, I wouldn't set one up if I knew. I think my biggest lesson from this is don't full trust the Microsoft guy if he makes it sound super easy & fuss free!
