I do not understand. I reinstalled my Slimbook OS. After reboot, seems like the user account for linux is created after the reboot. But anyways, I signed in Firefox, got my extensions, passwords, and also my Multi-Account Containers saved containers.

I upgraded system and rebooted and Slimbook OS created a new account. So, I had to login to Firefox again and do the same. But this time, got extensions, passwords but not the Containers. What the heck ?!

What's wrong here ? I really would like my containers back.

Someone please help me.

Earlier I had a problem with Facebook. When I clicked on the Firefox icon on the task bar Facebook would open to my home page. Then, out of the blue, this afternoon, when I open Facebook, a small page would show up then Facebook would load. When I would close FB (x in upper right corner), that mysterious page of FB was there. Had to close it by clicking on the X in the upper right corner. Tried several things but could not get it to go away. So, I uninstalled/reinstalled Firefox. Got everything reinstalled. Now,when I click on the Firfox icon on the task bar, what comes up is the Facebook log-in page where I have to enter ID/password. Before, Facebook would open automatically. Any idea why this is happening and how do I get FB to open automatically like before? Thanks

So anytime about a month ago, everytime I boot up my PC then first thing I do is double click on Firefox to open it and that worked fine until a month ago, now when I do it youll see the circle spin for 1 second and spot but Firefox doent open, no matter how many times I click on it, the only way Ive gotten it to work is that I have to restart my pc and try again until it eventually DOES open when I click on it, I usually have to restart 3-5 times before itll open.

Im wondering why that is and how to fix it? I havent done anything new to my PC since then, no new Firefox addons, also if there was a problem with Firefox itself then restarting should never make it open yet it eventually works after a few restarts. soooo i cant be Firefox right? Ive also tried refreshing firefox as well as going to add and remove programs and uninstalled it then reinstalled it the issue still remains, any way to fix this?

Google chrome, Microsoft edge (they recently added Uzbek languages, I think because I gave a feedback) and Brave supports Uzbek language. I do not directly translate the website from English to Uzbek but I want to learn some words while I am browsing by just selecting it and the quick translation. Google Chrome has an extension (Google translate extension) which can do this even more efficiently. But this extension in Firefox doesn't do it. I want one thing: please add Uzbek language so that I will be able to just click the words and see the quick definition. Or at least, if you cannot add Uzbek, please add a feature that enables me to click the word and the short English definition (let's say like Cambridge Dictionary or AI). It would also be helpful for my education.

I recently updated my Mac OS to 15.4, and for whatever reason, ever since I did, Firefox stopped working. I can open it, but if I try to go to any web site it just has a dot bouncing back and forth like it looks like it's trying to go to the site, but then it times out. I have deleted and re-installed Firefox several times - the last one being version 137.0.2 for Mac, but it still won't open any site. I don't know what to do to get it working and Mac tech support had no ideas other than to contact Mozilla tech support, so here I am. Can you help me? This has never happened before and it makes no sense that it would not work. You can see by the enclosed screen shot that it opens, but fails to open any photos or go beyond that. The 'checking for updates' alert just keeps spinning and spinning. Rick Garside

Hello! I'm trying to download a quantity of audio files from a specific website. Once I open firefox, I can manage to download a few in that session - anywhere from 1 to 10 usually. Then, at some point, the downloads start to hang. They appear as how they do when they're loading - "Unknown time left - 0 bytes (0 bytes/sec)". However, they never load. The only solution is to restart Firefox, to be able to download a few more.

I'm on Linux mint, Firefox version 137.0.2 (64-bit). I tried running firefox through the terminal to see if anything would show up when the downloads stop working, and I got this:

And a lot of "ATTENTION: default value of option mesa_glthread overridden by environment." - but those seem to happen all the time during regular usage.

Any way I can go about troubleshooting this, or am I stuck with restarting Firefox every few files I need to download? Thank you in advance for any help or advice.

As the first screen capture shows (sorry it's in spanish), my PDF documents tend to not print on the full page, but rather only on the top left corner of it, i've already fiddled with the scaling and fit to page, i have cleared the printer settings from mozilla, still the same, ive gone into the about:config menu and changed paper_height, paper_width, shrink_to_fit, and scaling nothing works. The document prints fine on Edge (screenshot 2), no problems with fit, and what's even crazier is that some PDF files work just fine (Screenshot 3). Honestly i have no clue what else to do.

If I use the close window shortcut (ctrl+shift+w) in Firefox it fails to close the window and treats every action I try to take as if the shift and ctrl keys were held down. For example, clicking on a tab will select it as if I were trying to move it as a group, rather than switching to it. Or, pressing only the T key will reopen closed tabs as if I had pressed ctrl+shift+T. This behavior will persist in Firefox until I close out of it completely and reopen. This does not occur when any other application is focused and ctrl+shift+w is pressed, and the effects are isolated to Firefox only when it does occur. Due to this, I do not believe that it is a hardware issue, eg. my keys just getting stuck. I haven't seen anything online that even vaguely resembles this issue. Any solution would be appreciated, even if it is disabling the ctrl+shift+w shortcut, as I keep pressing it out of habit and needing to close and reopen all of my tabs.

I have an Office 365 account through work and I'm using Copilot frequently. In Firefox I have a pinned tab for Copilot.

In recent weeks I've run into issues where the Copilot page stays essentially blank, i.e. the message field to enter text does no longer appear. The Office Toolbar still appears and when I switch to other Office365 sites like OneDrive and Home they work just fine. The problem only exists with the Copilot page. Refreshing the page does not solve the problem.

I found a temporary work-around by clocking on the lock-button in the address bar and selecting "Clear cookies and site data...". After doing this and refreshing the page it works fine again, but only for a while (like maybe the rest of the day). I don't know exactly what makes it break, but it seems like I have to apply the work-around on a daily basis almost.

Additional Info: I've been using this setup for at least a year and the problem only appeared in the last few weeks. If I open Copilot in either Chrome or Edge I don't have this problem (but I also don't want to use Chrome or Edge).
