firefox stalls on ubuntu and the OS says it is running but I cannot or don't know how to restart/reset it from the terminal. A reboot of the computer solves the issue but I have to re enter the bios password etc. Is there a simple solution?

Firefox closed the browser for an automatic update two days ago, and when it came up back after the update all my open windows and tabs simply disappeared. History tab was reset to a blank page, there was no trace of anything. I tried the access through 'Menu / History / Recently closed windows' or '.../ Recently closed tabs' and they were both blank, empty, zero, nada ... This is the first time it happens to me, and I'm surprised and disappointed that such a predictable and basic bug shows up on an update.

I have a couple dozen tabs I use for task f-ups, it' unproductive and annoying to get them all back up to work. If this happens again I doubt I keep using Firefox as my preferred browser.

1. Anybody else suffering the same issue?
2. Is there a cure for the problem?

Firefox has been running incredibly slow. I currently only have this window open, but if I open my task manger it shows 10 Firefox windows running. If I right click and end task, it will end the task, but shortly there after a new one will pop up. 1 of the is running in efficiency mode. I assume this is what is slowing down performance, but I do not know how to fix.

(April 2025) So suddenly, after my most recent FF update, if I have a document open in FF and hit "print" and choose "use system dialog box" (or whatever the exact wording is), Firefox Print opens up instead of my usual system dialog box. Why is this happening, and is there a setting I can change to DEFAULT to the regular SYSTEM PRINT dialog box instead.

I do not like FF Print. It prints one page at a time w/ like a minute pause between pages in a multi page document. And when I need more settings, it opens up the HP dialog box anyway, so wtf is the point? I just want my system dialog box back where all my print settings are in one place.

Thank you for any help!

I can't download ANYTHING on Firefox I've been tempted to switch to Chrome again because of this like why can I not download I don't THINK I did anything wrong either and it's really becoming frustrating I'm sorry

After installing the latest version of Firefox on Windows 11 I can no longer view certain sites (like Allstate.com). Tried clearing data, uninstalling/disabling all extensions and addons, etc., nothing works. Previous version worked fine. Love Firefox, been using for years (before Edge and Chrome came out), still, seems to slowly getting less functional as many sites I simply need to open in Edge or Chrome. Sad as I think that Firefox is the best browser, but, if most sites are developed with Chrome/Edge in mind then Firefox will fall behind in terms of compatibility.

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!

This issue came up in early April 2025.

Programs other than Firefox (e.g. Edge, Media Player) behave normally: when playing sound, if nothing is plugged into the 3.5 mm jack, the sound comes from the desktop's external speakers; and when an audio device (speakers or headphones) is plugged into the 3.5 mm jack, the sound instead comes from that device.

Where as Firefox will play using the internal speakers as expected, but when a device is plugged into the 3.5 mm jack, no sound signal goes to that device.

It seems then that the hardware is okay, and the problem must lie within Firefox, or within a Windows setting that is very specific to Firefox.

The sudden onset earlier this month may point to either a Firefox update, or (less likely) a Windows update.

Hello,

I never received a confirmation code to sync with my other computer. I've tried to followed all the instruction per request, still no avi.

I've followed below instruciton from your team:

   Add accounts@firefox.com to your whitelist/address book. After that you, will need to trigger another confirmation email by trying to sign into your account again.
   Check that you’re using the correct email address. Very often the email you’re trying to sign in with is not the email the account was created with.

I installed Firefox on a new steam deck. The device comes with an icon to download and install the browser. steam''' I get a 500 error when I try to log in. The login page never appears.

Can’t launch Firefox 3.5.19 on Linux Ubuntu When trying to run with:

./firefox

Terminal gives the following:

./firefox-bin: error while loading shared libraries: libdbus-glib-1.so.2: cannot open shared object file: No such file or directory

The last couple of updates seem to have impacted capabilities on Youtube. Specifically, under notifications, when you click the 3 dot option menu, the menu decouples from the option menu and goes to the top of the screen. Not the worst thing in the world but is incredibly annoying when trying to clear/hide multiple items.
