I am unable to get printing to work correctly using Firefox with Epson POS TM-T20 thermal printers we have a work.

We're currently running Firefox on Debian 12. I've tried both the ESR version that comes with the Debian repository and the latest Firefox as a flatpak.

When printing to the receipt printer, the only thing that is printed is the left-hand most part of the logo and a little part of the text and this occurs towards the right-hand side of the paper. I've changing all of the settings, resetting the settings for the print in about:config, but nothing seems to work.

I'd love to get this working so that staff could use Firefox. I'm attaching an image of what the print job looks like and a screenshot of what the print-preview shows.

Hello,

My name is Grey, and I'm experiencing an issue using Firefox as a browser to open my Outlook mail. For the past three days I have not been able to open any emails as a network error screen appears. Using other devices and other browsers like Edge, the emails open fine, so it is not actually a network issue. This problem only occurs using Firefox, and specifically with Outlook emails. Everything else functions fine and I have not made any changes, besides the regular Firefox update. My computer is also up to date.

What can I do about this issue? I appreciate the advice,

grey

I downloaded the new update this morning and I cannot separate my categories any longer on my home page. I keep them in categories on the 4 separate rows and then separate them by skipping a square. I cannot do that any longer and do not like the jumble of the homepage now. How can I keep the blank spaces that are located at the bottom of the rows to separate my categories?

How do I turn off those annoying "update available" notifications/reminders that keep popping up? I've gone into Settings, and in the Updates section firefox only let's me select auto updates or check for updates. I searched online but couldn't seem to find anything about how to disable the notifications all together with the newer version of FF. It's driving me crazy, thinking of switching browsers because of this. Thanks in advance!

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)

I've been having problems with some websites not displaying content, others displaying error messages. So have been going through the Troubleshooting Mode and diagnostic process.

The cause is the MS CoPilot extension for Firefox.

Useful in other ways as I discovered several other extensions I don't need, hence have remained disabled.
