Firefox takes about 5 minutes to load every it launches, before working smoothly like it should. This problem occured first time yesterday morning, and I have no idea what could have caused it.

It happens :

  • when I launch firefox normally (whatever the profile)
  • when I launch it from the terminal (it provides no output at all)
  • when I tell it to launch the Profile Manager (5 minutes to see the Profile Manager appear, then 5 more minutes to launch firefox using the selected profile)

It does not happen :

  • when I click "New Window" inside an existing firefox process
  • when I call `firefox --help` from the terminal

Here's what I've tried :

  • First, I've seen pretty much every article from Mozilla Support, Reddit or SuperUser (writing this question is kind of my last resort)
  • I've tried removing and then reinstalling Firefox from Flatpak, from the Fedora repos (using `sudo dnf install firefox`) and using the manual install via the archive (v125)
  • I've tried downgrading firefox (when using the package manager install) from v125 to v124
  • I've also tried the Firefox Developer Edition, same problem here
  • I've tried using the "Refresh Firefox" feature and restarting in Troubleshoot Mode (both are also affected by the slow startup, which makes them particularly painful to execute)
  • I've tried manually deleting the `~/.mozilla/` folder (= manually deleting my profiles)

When firefox launches, it does not freezes my OS and does not seem to use many system ressources : CPU usage is normal, RAM as well, and it does not seem to read many things from the disk as well (I've seen some threads where this was the issue).

And here is something interesting that I discovered :

  • loading (including refreshing) `about:profiles` is also slow and this time freezes firefox (OS reports it as not responding, I can't switch tabs and I can't see my mouse). Other about pages seem to work fine (although I did not try them all)

Thanks !

PS : Even if I think it has nothing to do with the issue, I prefer to mention it here : I was messing with virtual machines yesterday when the issue occured for the first time. My disk got full at some point and I don't know but it might have messed with firefox. At this stage, I had not deleted any files that could relate somehow to Firefox, that's why I doubt it would have caused anything harmful to Firefox. (instead, I mounted an empty partition from my disk to get some space)

Hi, first the last update tried a few times over some days to install. Never got confirmation that it has been installed successfully. When I go to "About Firefox" I'm getting the information that I'm using the latest version.

Now I have problems, mainly when using facebook (especially when I try to play games through facebook) that Firefox uses enormous amounts of CPU and Memory. This does not happen all the time but at least in 70% of tries. I attached 2 screenshots

If this happens I'm not able to close Firefox the normal way but have to kill the process in the task manager.

Any quick help would be appreciated. I would also like to know if I'm the only one experiencing this or if it's a common problem.

I solve it manually by resizing the page, so they load.

Where could the problem be? In the animation of their site? Do you have any advice on a fix?

I have started posting bugs of Firefox in Bugzilla for almost 6 months now(though the number of bugs is 3). I have noticed that the bugs really had no response for nearly then(almost 6 months), so is it the way bugs are handled?, like they take long time to address( just asking as I though the process to be relatively fast) or is it something that I might be doing wrong in reporting a bug. I searched online and have been looking at assigning the bug( what I understood). So, how to do it if there exists something like assigning and will it increase the movement on my bugs??

There are a few websites (e.g., https://thehermitagehotel.com/) that show up as a white screen (see attached) when I visit them from Firefox using my usual settings, but show up correctly if I use Firefox in private browsing mode. Turning off enhanced tracking protection does not resolve the problem. My browser privacy in Settings is set to "Custom" with everything checked, but changing to Standard and reloading the site does not fix the issue. As I noted above, the only thing that works is to open the site in private browsing mode. Most sites work fine. This problem is limited to 2-3 websites. My version of Firefox is 125.0.1 .
