i will use firefox all day tomorrow as I usually watch a lot of videos and see if my storage space changes while I am using it

i only found 1 person with anything similar. It was the reddit link from before. So its hard to find clues to use to search for an answer

did you clean install win 10 on new ssd? maybe it was the update that caused it then and its not doing it now?

with so much free space now, it shouldn't really matter if it expands during use and gives it back on shutdown.

After having my ssd lose almost 40gb randomly, I tried a program called spacesniffer and ran it as admin after closing firefox, I was around 308 before closing firefox, after firefox closed was at 328gb, after rebooting was at 340. But I noticed after checking the space sniffer before and after resetting that something called pagefile.sys was 29.1gb before resetting and 19gb after resetting, that probably the cause of the eaten space?

Absolutely the pagefile will do this.
It is not a function of Firefox, but rather Windows.

How much RAM do you have in this system? You can probably change the pagefile settings to something more reasonable, that doesn't go up and down all the time.
