A user I am servicing uses Firefox every day. They are on Windows 11. Every afternoon (sometimes at other times), Firefox stops working and loses its internet connection (everything else on their computer continues to be connected). When they close and restart Firefox to reconnect, it then tells me the user that they are using an old profile and need to create a new one. They're able to re-log into their Firefox account, which eventually resyncs all their data, but they then have to re-sign into everything, which is a major inconvenience. The only workaround the I have found is to reinstall Firefox, ever time this happens which then allows the user to use all their settings until they have to repeat the process the next day (i.e., everything remains signed in and/or logging back in is easier than described above). Here's some additional information and trouble testing we've conducted: Uninstall and Reinstall of Fire fox Check for updates (Updated to new version and still suffered the same issue) Cleared cache and cookies No extensions Please if anyone has any advice or recommendations it would be greatly appreciated. I made my post originally on the 3/9/26 but no one has gotten back to me, so I am creating another post.
