I got a new laptop about 6 months ago and have refused to install Chrome on it.
For the few cases where I need anything Google related, I use Edge. Basically, Edge gets all my Google related tabs, and Firefox with uBlock Origin gets the rest of my browsing.
I did have to train myself not to control-click links in Gmail though, and instead copy-link, paste-into-Firefox.
I almost never have issues, so maybe it is your plugins that are causing issues (or maybe android ff is different than ff for Mac?)
