If you're already using Chrome you likely don't care much about free software, but to address your specific complaints I would recommend GNU Icecat! It strips out some things like pocket, has some about:config tweaks out of the box with privacy in mind, etc. I will give the unfortunate tip that you should probably disable librejs which comes with it out of the box. I am not against its goal, but it breaks so much stuff. I also use umatrix and ublock origin so I already am often clicking around to unbreak a page. I didn't deal well with adding librejs on top of that. That said, if I made my own website, I'd strive for librejs compatibility for sure.
