How so? Celeron, 2GB of RAM, ~4GB with compressed ZRAM. Libreoffice works, most stuff works with GL 2.1, even 720p video with MPV. LibreOffice, Ted, Abiword, GNUMeric...
For the rest, UBlock Origin it's your friend and git://bitreich.org/privacy-haters to cut in half the realistical Chromium requeriments.
Avoid brave. It' s spyware. If any, Chromium-Ungoogle with the settings from:
git clone git://bitreich.org/privacy-haters
Copy the file in the chromium subdir to /etc/profile.d/chromium.sh. Chmod +x it. Change CHROMIUM_FLAGS to UNGOOGLED_CHROMIUM_FLAGS or whatever flag shows up in /usr/bin/ungoogled-chromium script.
That and UBlock Origin with the country specific ad blocking rules will cut down a good bunch of crap.
The GitHub repo I posted has sane defaults for both Chromium based browsers (adapt the environment variable for the custom fork, you have it at /usr/bin/chrom file) and Mozilla under *Nix. If something "clean" as Mozilla has a good chunk to be tweaked, just imagine the amount of telemetry Brave has.
I lived the 90's and 00's in computing. I pretty surely know the spyware and adware terms. And Brave it's spyware, period.
