Firefox Community Forum

This issue seems to be getting worse as time goes on. I have to go to another browser to use Cabella's, Nextdoor, and several others. sometimes I get bad request when using a link or in the case of Cabela's I can not navigate their site. Lately I have been getting a warning of dangerous site when I hit the link in an email for all the forums that I belong to.

I love Firefox's bookmark system, other wise I would just use another browser, but I'm hoping you can correct these issues for me.

Thanks, Jim Roney (long time user)

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.

If you have questions about the update or need help with the process, this is the place to ask! Whether you’re just starting or you’ve already updated and want to share your experience, we’d love to hear from you.

Let’s come together, share tips, and ensure we’re all prepared. Drop your questions or insights below!

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?

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
