I use Firefox because I really like the containers extension that makes sure each tab is its own environment to prevent cross contamination of cookies etc. Also, I can rest assured that ublock origin is working as intended by the author since it is primarily targeted toward Firefox these days I think.
Sadly I had to stop using Firefox on my gaming Windows box because for whatever reason my Firefox install seems to gobble up all of my GPU memory. It's working fine on Mac and Linux though.
I have the same issue but adding a heaping tablespoon of psyllium husks to the soylent really helps with the fullness problem.
