Favorite/Best lightweight browser for low ram?

In this beautiful holiday season I chose the worst possible time to build a new pc, but I was already neck deep in it by the time I saw ram prices so I had to commit. My finished build is using ram I got for free bundled with my mobo becuase I can't and won't buy ram for 400 dollars. So my 4080 and r7 9800 may be slightly bottlenecked

that being established what is everyone's favorite browser to use while gaming during these trying times to save every megabyte?
