for privacy:

• ublock origin (default settings)
• noscript
• privacy badger (by eff)
• canvasblocker
• localcdn
• clearurls

additionally, i also use bitwarden for password managing, libredirect for automatically redirecting to alternative privacy front-ends, xbrowsersync for syncing bookmarks, and snowflake for tor censorship circumvention.

none. chromium is a google (-endorsed) product, who put their own little tracking tidbits into the chromium project. if you still want to use a chromium-based browser, i have two ‘suggestions’:

• brave. renowned in the privacy community but has had a few suspicious moments, and honestly i just don’t trust their whole big-tech thing they got going on.
• ungoogled-chromium. basically just the chromium browser but without the google shit in it. no extra privacy-advancing features as far as i’m aware though, and extensions don’t seem to work.

now if you really want a good browser, go for either of the following firefox-like browsers:

• firefox with arkenfox user.js. firefox as you know and love it, with the arkenfox privacy tinkering. i haven’t tested it and its apparently a bit difficult to install and configure, but i’ve heard its really helpful with privacy.
• librewolf. a privacy-first firefox fork developed by an independent developer and contributors, no big-tech bullshit. my personal daily driver.

anyway, sorry for the rant, but there u go.

i’d probably say naomi brockwell’s nbtv. idk why but she explains things so easily and makes some okay recommendations. i wouldn’t say she gives the best recommendations but her channel is the one i always come back to.
