Firefox 128 (windows 10 pro) just did something strange, it suddenly needed me to close it in task manager, changed languages when restarted
At first, youtube had a glitch while I was watching a video, all the suggestions were from the same account on the right, and the rest of the screen was greyed out. Then it came back but the video played with a lot of skipping (I have 1gbps FTTH fibre, so that should not happen) and then it started to eat up a whole lot of memory with one firefox process being at 3gb of ram. I closed Firefox in Task Manager and then after waiting a bit for the system to stabilize, when it finally did, I restarted Firefox and it now was in French (Canadian), I am Canadian so I guess me adding the language to firefox for when I am typing in french is why it was there, but my default language was US English. The Restore session window was in French (CA) and I had to change it in the options.
Don't know what happened here exactly, but I thought I should report it, since I have telemetry turned off. It's working fine again, so maybe I could just blame windows, when I boot in Ubuntu 22.04 there's never a hiccup.
