Firefox was using GOBS of CPU, so I killed the master process and relaunched, but after launch I couldn't get any pages to finish loading. I then hoped to copy URLs from tabs and paste them into Floorp (which is working fine, as is Chrome), but I couldn't even snag the URLs (dominated by YouTube pages). I ran a full-system virus scan, finding nothing. The most recent Windows-11 update on 2026-Jan-15 isn't recent enough to be a likely causal factor. Firefox has about twice as many extensions as Floorp, but it was running fine until late yesterday (it's now after 3AM). I couldn't get the extensions page to load, so I've attached a screenshot of C:\Users\Mike2\AppData\Roaming\Mozilla\Firefox\Profiles\oa7ou5xk.default-release-1715337056307\extensions There are several other profiles, but there's very little in them (one profile with a times.json & several profiles containing a parent.lock file) Processor Intel Core i9-9980HK CPU @ 2.40GHz (2.40 GHz) Installed RAM 128 GB System type 64-bit operating system, x64-based processor MSI GT75 Titan 9SG If I reinstall, will I lose all of my tabs?
