Firefox Community Forum

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).

in FF 137.02 Win11Pro there is no reopen previous session option in the history menu, even though in settings, history, "firefox will" is set to remember history. We tried reinstalling FF. No luck.

Is there a way to reopen the previous session?

Has that feature been deleted?

Hello,

Earlier today I reformatted my device but when I logged in to firefox I can only see my history is getting synced my bookmarks are empty, I've checked and bookmarks are check off and they should be synced. How do I get them to sync? It has worked fine in the past. Thanks.

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.

I'm attempting to set up Firefox in a newly installed OS and have logged into my Sync account. Many aspects seem to be loaded in, but the status via the Settings is stuck at "Syncing..." despite waiting several hours. Quitting Firefox results in a crash window popping up.

There are no files in the weave/logs directory. The weave/failed directory has multiple json files; most almost completely empty. addons.json has an ID, but that's pretty much it.

Deleting the .mozilla directory and starting over yielded no change in behavior.

Any help would be appreciated. Thank you.

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?

windows 10 is up to date firefox is up to date (137.02 64 bit) dark theme

there is no bookmark sidebar button at the right of the address bar

I am running firefox in 5 windows with at least 7 tabs each every time i exit, reopen of update it i have more that 35 Bookmark LEFT Side Bars to close IF i have the patience to close all of them WHICH NEVER HAPPENS... (this is happening since too long, I am pissed off...)

I searched, tried a couple of "solutions" to no avail

When you right-click on a window thumbnail, a menu should appear, but instead the window thumbnail just disappears. The screenshots show 1) a Firefox mini-window 2) a mini-window that just disappeared when you right-click 3) a mini-window of any other program 4) the menu that appeared is as it should be Otherwise the browser works absolutely fine for a long time. But this problem causes a lot of inconvenience because I have 2 monitors.

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.

How do I remove "firefox browser being managed by your organisation" . I have looked at several posts and don't understand a word of it. I recently re-installed Firefox and lost all my passwords but still have bookmarks, every time I turn off firefox it forgets my account sign in, I then get an email to say I have signged in on a new device. I suspect it is the Norton 360 security software. Please can someone explain in simple terms how to remove it. I have tried contacting Norton but their support is worse than Microsoft.
