even basic fullhd can pull several gigs per hour, per stream.
my adopted dad used to hit their old 8gb per month jetpak quota in one weekend just refreshing a local auction site (they don't stream or so much other than email and banking at home otherwise)
none. 15 year old apu, slow laptop hdd, 2gb ram (some consumed by the graphics). cpu performance of the earliest s939 dual core athlons.
put a puppy or antix on it, i guess, and hope for the best. with the 8gb max and a small sata ssd it could run something more mainstream.
update to add: i just reinstalled the latest antix-full over the top of my old one that runs on an old athlon dual core (am2+ 4gb and hdd). creeps a bit over 1gb ram used once you load a page up in firefox. it'll be 'usable', i guess, running one thing at a time and not going crazy with open tabs and windows. still gonna go back on the recycle pile though. i have too many of this era desktop, no takers for them, and not enough room to store 'em.
the 'best' one that i personally use is proton. i don't really use email all that much myself, so even the free plan is more than adequate. the free webui is basic and it has upsells scattered about, but it's fast and responsive and 'enough' for me. third-party clients like thunderbird require a paid plan and their mail 'bridge' software (a local proxy your client connects to, that handles the encryption and actual transfer of the mail bits).
i did recently set someone up on namecheap for mail when we were registering a domain for them, too. fast and easy to set up. so far (it's been about six weeks now) rock solid reliable and has been a good choice for them.
i know that. i suggested the bug report because snaps themselves do report strict confinement even though snap debug doesn't list that confinement option's availability.
i am in the u.s. my high school (~ 40 years ago) offered spanish, french, german, and swedish. the district had asl classes but that was outside of school and open to the community. juniors and seniors could take classes at a nearby college, which opened up other language choices.
if the orange shithead wants to set a precedent where leaders and administrators of a nation are criminally liable for their actions... he needs to be first in line to submit to whatever charges any nation or state wants to bring-up against him.
there are a few addons for firefox that can automatically clear cookies and some other browser data. cookie auto delete is one that comes to mind but i dunno if it'll clean up everything you'd like to.
firefox now also has a toolbar button for private mode to do that for private windows. click and the current private session 'data' is destroyed so you don't have to close all your private windows and re-open a new one to 'start over'.
i separate my 'logged in' use from my 'regular' or 'anonymous' use with different browsers. currently using firefox standard release for one, dev-edition for the other. they can run side-by-side and don't interfere with one another.
you could do the same with different profiles, too, and create shortcuts that open up the browser directly into a specific profile. i've just always used different browsers--been doing it this way since before firefox even existed. container tabs, private browsing, and all that didn't exist back then.
each browser or profile can have its own settings and mix of addons, suitable for its intended use.
