Important update! On March 14, 2025, a critical root certificate in Firefox will expire. If you’re still using an older version (before Firefox 128 or ESR 115.13+), it’s crucial to update to Firefox 128 or newer to avoid issues with add-ons, DRM-protected content, and other features.

For full details, check out Update Firefox to prevent add-ons issues from root certificate expiration.

When i use PIP in Debian 12 using desktop environment XFCE, I cannot move the PIP to another desktop using alt+space. The menu is greyed out.

this prevents me from moving the PIP to another screen. Is there a solution?

The website WSJ has large areas on front page, including the opinion listing, are simply white and not 'there' on the page to click on. I've deleted their cookies without effect, tried turning off all adblockers, shut mac down to reboot, nothing seems to have an effect. This is a recent glitch of only several days, prior performance was great. Thanks!

Starting this morning I am no longer able to access my banking site with Firefox. My current version of FF is 133.0.3 for 64 bit Windows 11. I could access it yesterday. Looking at the support on this, I see that this has been a problem with Firefox for quite a while. I can access my bank with Chrome (although I don't trust Chrome) so why not FF? I haven't changed any settings. What set this blockage off and how can it be eliminated. If a setting needs to be changed, please tell me what it is and how to fix it.

My account on thinkific is cookingasmedicine.thinkific.com When I go to the "course" and click on a video whether in my class or one I am taking, the videos will NOT play. I have been talking with Thinkific and we've gone through all the videos of yours and theirs - the settings, checked my updates and nothing works. I have no trouble on my laptop or my Iphone using firefox on laptop just on my desktop LENOVO.

I checked my set up that is on the laptop and made it exactly the same on my desktop but STILL to no avail. The videos will simply NOT play!

Would you please help me?

I have Windows 10 and currently have auto updates so I am up to date with your updates. I just can't imagine what it could be that's stopping the videos from playing? They played perfectly for three years! I have not put any new apps or programs on my computer either.

Thank you, Claire

I have looked on the web and continue to find all sorts of references on how to configure your browser to open the tabs I had open last time I closed the browser. I have the "Open previous windows and tabs" checked in the General settings....and it doesn't work! How is that? Any special thing I need to do to get it to work?

Why do I have to re-register with my banking website to remember my settings in order to not need two-factor authentication? I have selected in Preferences/settings for that website's cookies, etc, to be retained in Firefox.

Dear Sir/Madam,

I have recently found some sites that do not open in Firefox, however, in Chrome everyhing is fine. This was one of them: https://sciendo.com/article/10.2478/jdis-2025-0002

The other one was a login page for an Admin site - that is not suitable for testing, since it contains confidential data.

Could you please check it?

Thanks, Krisztina Kőrösi

So i reinstalled my graphics driver yesterday, and after that when i open a pdf on firefox it only shows blackscreen. it didnt happen on other browsers(chrome, edge)

After a recent update to Firefox Nighty, the error "Procedure entry point IsWow64Process2 not found in DLL xul.dll" began to appear. I am using Windows 10 1507 LTSB.

Hi. I use firefox version 133.03 (64 bit) and have issues when on x.com's website. It will randomly open new tabs constantly. I have tried multiple options with settings on firefox and my pc, blocked new windows from opening, and disabled pop-ups. Checked my extensions and tried disabling all and that did not affect anything. I have run scans for viruses, malware, etc., and nothing comes up.

Any advice? It gets pretty annoying having to close the repeating tabs to be able to view the site.

Yes I typed about:config and set everything containing "translate" to false. Yes I changed browser settings, yes I deleted translation dictionaries AND THIS PIECE OF TURD STILL SCREWS WITH ME

Am I the only one here? What will it forking take to disable that crap?! Disabling the moron of coder who made it?? HELP ME GOD
