Over the past week I've had this error popup a few times when Firefox is launched:
"You've launched an older version of Firefox. Using an older version of Firefox can corrupt bookmarks and browsing history already saved to an existing Firefox profile. To protect your information, create a new profile for this installation of Firefox."
I haven't yet spotted a pattern, but the most recent time it happened, I had the browser already open and either opened a new window or clicked Firefox in my start menu. The new window showed my homepage (blank tab) but was unresponsive: I couldn't type into the address bar, click a bookmark, or even close the window. The existing window was fine, so I closed that but had to kill Firefox in Task Manager.
When I relaunched Firefox, I got the above error message. Luckily I use Sync, so my many bookmarks are backed up. But of course all cookies have been deleted, so I have to login to websites again.
Firefox is up-to-date (84.0.1, 64-bit) and running on Windows 10 Enterprise. I even uninstalled, cleared out the data in AppData\Roaming\Mozilla (plus Local and LocalLow), and reinstalled.
As I said, this has happened a few times over the last week (3 or 4?) and is starting to get annoying now!
Any ideas? Thanks!
