I have a problem where if I install the packages needed to get hardware video decoding working in firefox it completely breaks YouTube playback. I can't find any info on the internet about the problem and I am having a lot of trouble with it. YouTube playback with libva-mesa-driver and libva-vdpau-driver will start stop restart start playing audio then crash with a this error every single time. I am at my wits end trying to figure out this problem and I would love help figuring out the problem I am using firefox-developer-edition as a note thanks Ozzy

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.

Others asked and were pointed to extensions. As long as extensions get access to my pages, I'm not willing to use any. So, is there an option in advanced settings, to return to previously viewed tab when I close a tab? Thanks, Cat

I don't want to be able to scroll the page by selecting text. That's what the scroll wheel is for. More often than not this 'feature' just results in frustration as scrolling the page selects more text. Can I just disable this altogether somehow?

So I have an Excel workbook in my onedrive from MS, It was working fine on my firefox browser in my Ubuntu OS, last week it started to delete my cell's information whenever I pressed the enter, tab or arrow keys, I contacted the MS support and they get me to opened the same file on a chrome browser and worked fine... I still want to use my firefox browser but this problem is very annoying, please help me sort it out!!!
