need a Chromium browser for technical reasons
With a similar use case, after messing around with Brave, then Ungoogled Chromium for a few years, I just reinstalled Google Chrome last month. I literally only need it for making sure webdesign stuff I do works okay in Chrome, and for the extremely rare websites I come across that refuses to work in Firefox 🤷 I didn’t change any settings or install even an adblocker, to make sure I’m testing as close to the “vanilla” experience as possible. I also don’t log into any accounts with it, so I don’t really care if Google sees what I do for that 2-3 page visits / month that I use it.
