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.

Because the browser was just an example, this tool handles a lot of different softwares. Sometimes it can even be software you deleted that left cache behind.

I trust this tool as it has been around for a very long time, is well known and open source. But I haven't used it in years as drive space is now cheap so I'm not trying to reclaim every last bit of it. It can still be useful in some situations but no need to use it regularly.

Other software has similar behavior and this could do the same thing for, conceivably, all of them.

I could see a world where I would run something like this every 5 years and be surprised how much crap just accumulated over that time.
