Cuz there are more than just browser caches I would like to nuke.

Cuz bleachbit is more granular, seperating out site data and cookies, enabling me to delete the 1gb alpine docker image downloaded by https://github.com/MercuryWorkshop/anuraOS without logging me out of anything that is using cookies. Firefox doesn't appear to have that option.

Edit: cuz I use multiple browser profiles, and this can delete cache from all of them at once instead of me having to do it once per profile 2-3 times.
