After the most recent upgrades (both MacOS to 26.4 beta and Firefox 147.0.4), Firefox is giving me this message: Hmm. We’re having trouble finding that site. Any suggestions?

Dear Everyone, Facing issue with deploying Configuration Profile for Extension Settings via Intune. I have already imported the "firefox.admx and mozilla.admx". then i created the firefox Extension using OMA-URI as show below

OMA-URI: ./Device/Vendor/MSFT/Policy/Config/Firefox~Policy~firefox~Extensions/ExtensionSettings

for about 8 years now, on and off, on hundreds of OS-es, clean installs of firefox etc. sometimes - not always - typing into the firefox search bar and pressing enter does nothing

i have bit-warden, u-block-origin and stylus installed (but they shouldn't be running on the 'new-tab-page' - is my firefox sync-profile containing some firefox-breaking-errors? (latest Win-11)

On outlook.com sign in with password does not work. It gives "Please retry with a different device or other authentication method to sign in." Works fine in edge.

I just had a firefox tab with a pop up asking me to try ai features... my options were "yes" or "maybe later". How do I stop the slop sales? I want ZERO pop ups... from Mozilla or anyone else! I didnt see settings that would disable mozilla sales pop ups - is there some way to turn these off permanently? I have already turned off the ai features. Really appreciate any suggestions!

I have an issue where the following operations with the "new" profile manager don't work: - setting up a new profile (about:newprofile in the new profile is just blank) (a new profile gets created though) - deleting a profile (about:newprofile is just blank) - editing any profile that is not the original profile (about:editprofile is just blank) (works with the original profile) - the select profile interface from the account or menu button is blank when opening it from any profile that is not the original profile

What works tho is calling about:profilemanager from any profile. From there any profile can be selected and switched to.

I'm using the Bazzite (Linux distro that is Fedora based). I'm fairly new to Linux so that could be a issue, the problem was there from the get-go though and since Firefox was preinstalled I don't believe I could've messed up much.

Firefox version is 147.0.4 Bazzite version is 43.20260211.0 (Kinoite)

Reboot doesn't fix these issues. Uninstalled Firefox with deleting user data, installed it again and same behavior appears again.

I also tried installing a Firefox fork (Waterfox). It had the same issues.

I would appreciate any help and would be willing to share more detailed date if it helps somebody help me.

The attached screenshots mostly show the UI that is not working as expected.

As long as my computer doesn't go to sleep Im fine. If it does, when i open firefox, i must refresh to be able to find my bookmarks and passwords. What am I doing wrong? Thanks in advance! Micha

On my Firefox I have click something and choose Copilot. What I did have remove Chatgpt and enable Copilot. I want to have Chatgpt back but I cannot enabled. Please help?

My university website (brightspace) is blocked by "Warning: Potential Security Risk Ahead" and clicking advance does not allow me to continue. I was using brightspace when it suddenly became blocked and I have received errors stating it was an HSTS error to now an expired certificate. I have tried to restart Firefox and clearing the website from my history and clearing cache, but nothing worked so far. Accessing this website has only been an issue on my Firefox on my laptop. The website's servers is not having issues, my other devices can access it flawlessly, and using other web browsers on my laptop does not cause any issues. I would like not to switch my browser, so any help to accessing this website would be greatly appreciated
