Using Firefox 143.0 on Ubuntu 24.04, when loading PDFs into the browser window, the PDF does not get properly rendered. Instead, when scrolling part or all of the PDF just show the desktop or windows behind Firefox. This usually happens after opening several PDFs and then keeps happening until I restart Firefox. Is there an issue for this extremely annoying bug?

Ran into an interesting bug with Firefox since installing the macOS26 Dev beta. Whenever I use command space to bring up spotlight, Firefox become unresponsive, the beach ball will spin. It will only happen if Firefox is in focus when I use spotlight, and only if I am signed into Firefox sync.

I am not sure of a way to help replicate this issue as it seems to only happen when signed with Sync, but I would be happy to provide additional if I can.

Restarted Firefox (W10 PC) and all of my history and bookmarks are gone. The subdirectory is present but EMPTY.

In addition Firefox is not recording ANY history and will not accept ANY bookmarks. The bookmark button simply does not work.

every so often when i go to a site it acts like it is taking a screenshot and fades out and disappears to the bottom right corner.

i was wondering if that was a weird thing firefox is doing or maybe it is something on my end?
i tried to screen record it but it doesn't happen often enough to get a recording of it.

I recently got a new machine and loaded it with Linux Mint 21.3 - Cinnamon, FF 142.0 and Bitwarden Version: 2025.8.2 along with the usual cadre of extensions that I use on every other machine I have.

When I first start Firefox, Bitwarden autofill suggestions does not work, autofill from the "Fill" button in Bitwarden does not work and returns an error. The only thing that works is to individually and manually copy the username, paste it, then copy the password and paste it.

If I log out of Reddit and then try to log back in, the autofill suggestions works and the "Fill" button also works.

This is only on Firefox and only on the fresh start of the app. This does not occur on Chrome and I have not tried (and don't want to try) it on Windows.

I really appreciate this amazing new 'unloading' feature. It's just the function I need. However, I can't unload all the tabs I've selected. Only some of them are inactivated, and this problem occurs almost every time I choose a group of tabs.

Once in a while, my firefox has been randomly getting a mysterious tab appear and immediately disappear, leaving me no time to check what it was. There isn't a clear pattern to what triggers it or when does it happen... I think it happens like once or twice per day?

I assume it's just some buggy extension updating itself in the background or something like that, but I wanted to troubleshoot this issue just to be sure.

I wanted to check a log with details about previously opened/closed tabs, but these mysterious tabs leave no entries in the History at all. I searched around and couldn't find anything that helps me further. Is there anything like that I could check?

I'm not really sure if Troubleshoot Mode prevents this problem or not, since I haven't found a way to reliably reproduce it.

(I'm on 64-bit Windows, last observed this behavior on 142.0.1, but I updated to 143.0 just as I was about to post this)

getting unwanted notifications from d35nd28hubcc73d4frm0.spanchaintech claims its from Mozilla Firefox telling me Trojan Virus detected! System alert! McAfee license expired! and tries to direct me to a site taking payment to upgrade my McAfee account My McAfee account has not expired Running a scan reveals no viruses or problems BUT - I can't find how to get rid of the notifications How do I get rid of the notifications?

my password manager has deleted every single password I have which I do not memorize forcing me to start from scratch but I have valueable accounts that I do not remember the password to so is there a way you could return my passwords?

Have been having an issue for the past month or two where if left in the background firefox will slowly start to eat up my available ram. I was using it like this perfectly fine for years previous to now.

I dont have this issue when I'm actively using it, only when I tab away from it and specifically its not on screen. Once I tab back to firefox the ram usage immediately dips back down to normal. I have tried many things to try and solve this like doing a clean install of firefox, getting rid of extensions, clearing my browser cache, closing all other apps to verify it was just firefox, clearing my history, turning on hardware acceleration. Nothing seems to help, im really at a loss and I don't understand what changed besides it being updated in the past couple of months.

My computer is fairly heavy duty and I have 16gb of ddr4 ram that again was working perfectly fine to run firefox before these past couple of months. As a result of this issue however if left in the background for too long on accident firefox uses up all my idle ram and starts causing other programs to not be able to run and has even crashed my computer previously when trying to run a program like clip studio paint.

I have noticed that while running the firefox task manager there is definitely some difference in memory usage when i tab back in after letting it be in the background so I have attached screenshots of the regular usage while tabbed in and the captured usage when i tab back in.

Any possible solution is welcome because I really enjoy using firefox and i dont want to have to switch browsers unless absolutely necessary.

ATT is my internet service provider. I use their website as my home screen. Yesterday, I started getting an error message when I tried to go on-line. I have contacted ATT, and they have determined that the problem is with Firefox, and not their website. I can go from the ATT screen to any other website, and it works fine. This is the message that I get:

Secure Connection Failed

hi, I recently purchased a new wireless mouse and keyboard... and my only problem is that there are a couple extra buttons on my new mouse... roughly thumb position... and are by default set to navigate backward and forward.... I'm running ubuntu linux... which results in accidentally clicking back midway through a video or podcast and losing my position more often than you'd expect... any idea how I might either reassign or disable them entirely on the software side of things? thanks. -dan
