Firefox Community Forum

I run normal firefox on linux. Fully up-to-date. Every time I quit the app, it reverts to a version of my profile from a month ago, and loads all the tabs I had open then, and then receives all the tabs that I sent to the device in the interim (~1 month). As I speak, it just caught the 60 or 70 tabs in this window.

I tried changing the name of my profile folder to randomstring.defaultOLD and changed one of the backups to randomstring.default. This didn't change the behavior. I'm still stuck in the loop. I saved my tabs with onetab, because firefox isn't remembering my session anymore. I thought it was something to do with updates, like it only loses its mind upon updates, but that's not true. It thinks it's updating firefox EVERY TIME, because the one time it's loading to 1 month ago it was updating, but I'm 100% sure there are no updates to firefox in my linux. It's just hallucinating.

The articles on restoring from backup are outdated. They say to use an html file. There is no html file. It's just folders for profiles, not html files. HELP!

My primary password was change on June 16, 2026. I did not initiate the change, nor have information about the new password. I have recovery keys I would like to try. I am not certain whether when the password was changed the recovery keys were as well.

The first step in support instructions is to click >forgot password< button at sign it. There is no such button.

Since the latest version (152.0), right clicking on a file link, select Save As... and with the popup with the filename and saving location being OK just hitting <Enter> doesn't do anything anymore. I now have to specifically click the "Save" button (or use <Alt>+S) to get my file saved. This is highly annoying as my muscle memory gets in the way all the time. Please get the original behavior back. Just found out the same behavior is with file upload.

Firefox recently had an update, and now when I am uploading files, I can't double click to upload selected files. I have to first select the file, and then click the open button.

Before the latest Firefox update, I could simply double click on files to upload. This workflow was much faster.

If I go to about:config, and search for: widget.use-xdg-desktop-portal.file-picker, I can change the value from 0 to 2, and then I can upload files by double clicking. However, then Firefox forgets my last upload location, and always opens in the home folder.

If I set it back to 0, it remembers my last upload location, but I can't double click to open files.

My current Firefox version is 152.0.1. Any help would be appreciated. Thanks.

I would like to use built-in VPN and forward my traffice to Charles log. I enabled both by setting the proxy to Charles log. I found that nothing shown up in the Charles when VPN is on.

How can I do it?

Hello, I am using Linux Mint on a desktop with the latest version of Firefox. Two weeks ago I could login to the Discover website with no problems. Suddenly I can not log in, but get an error message that something is wrong and I can't login. I can login using Chrome on this machine. My wife gets the same message when she tried to login to her account on my computer. After several discussions with Discover, all I get is "it is not our problem."

I am having no problems logging into other accounts with Firefox on this computer.

I have not explicitly changed anything on the browser or computer. I have done some updates which included Firefox. I can login on a different Linux computer using an older version of Firefox. Of course the updates were also to the computer and I will ask the same question to the Linux forum.

I really like Firefox and would hate to have to change to Chrome.

Thanks so much for your help.

Wanted to change the shortcut Alt + number to Ctrl + number to go to Tab 1-8 (got used to it in Chrome and Edge).

Found this https://support.mozilla.org/en-US/kb/customize-keyboard-shortcuts-firefox and wanted to try it. about:keyboard did not work and showed that the address doesn't look right.

Oh yeah, my device is running Linux Mint Cinnamon 22.3.

Dear Support,

I have a Bug (in my opinion), that if select Settings --> Downloads "Files and applications - Choose how Firefox handles downloaded files and content." e.g. for PDF -> open in Firefox (P1.png), and I click on a PDF-Link, the File opens in Firefox and is not downloaded (P2.png). In the Settings if I select the Action "Always ask" (P3.png), click on the PDF-Link and choose "Open with Firefox" (P4.png), the File get downloaded too (P5.png). So it is open with Firefox and save File? I think this Action is not wanted.

Kind Regards Tobias

Hi all the people,

I was just surprised to see this in an Apache HTTP log: "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Firefox/58.0.1"

This bugs me. My first guess would be that a Webkit based Firefox could not be qualified as really Firefox. Although that, I could imagine a Firefox for iOS or MacOS based on Webkit, may be, but it says it is on Windows, which makes less sense.

I suspect this is a user agent string spoofing, but I just need to be sure (I try to get ride of far too invasive bots, while I’m afraid to disrupt browsing from legitimate web users).

With thanks and my apologizes for such a question which may looks obvious or strange to people who know for sure.

After connecting and signing in to Mozilla Connect, it seems impossible to actually log out. There is a log out option in the dropdown menu, but it doesn't work. After "logging out", when going back to the site one is automatically logged back in. This is true even after clearing all mozilla.org cookies, and closing the browser. If a different browser is used, first time access to the Mozilla Connect site requires username/email and password, but after the first access, the alternate browser is also perpetually logged in.

1. What mechanism is being used to identify me as the user after cookies are cleared ?

2. How does this fit in with Mozilla's claims to respecting user privacy ?

3. How do a log out of the Mozilla Connect site ?

On previous releases of Firefox, when I added the "Open file" button to the toolbar I could click on it and a file browser would open to select a file to load. Now in Firefox 152.0, I was able to add the button to the toolbar, but it is disabled (greyed out) and does nothing when I click on it.

The Ctrl-O keyboard combination works, but I much prefer to use the toolbar button.

I have a home server 192.168.0.240 in my local network. Firefox does not let me in to my own pages. On the address line appears text "Not secure",

I have found no way to get in. I have there REALLY IMPORTANT TOOLS AND MATERIAL and I need it AS SOON AS POSSIBLE !!!!

This is really stupid. I have used these pages until this weekend. I have had this problem many years, but always found some way to make it work. I am NOT going to buy a certificate to every server I have home. it costs $$$$.
