It's also worse on power. FF tends to drain my battery much faster than Chrome. That's with <20 tabs open, mostly light weight sites.

I'm still using FF as my main browser but will probably switch to Chrome again.

Swings and roundabouts. I find chrome uses much more memory, and the plugins I care about (tab group view, NoScript) don't have effective parallels in chrome last I looked. I also have a pet hate for any application which decides that it needs its own look-and-feel and you should discard your own window decorations.

Also, the mozilla entity is much more about preserving freedom, and I think that's worth the minor inconveniences you get from webdevs who think that chrome is the only browser in existence.

I thought Chrome was famous for being a resource hog. It consumes more RAM on my Windows PCs, though I confess I use more tabs than are viable in Chrome....

That's only in comparison to Safari and Edge. If you open enough tabs to cause memory issues on Chrome, Firefox would have frozen and slowed down to a crawl before filling the memory, anyhow, and electrolysis still isn't in a state where it could change that: there's still one process for the renderer so if enough intensive webpages are run your web browsing experience will still slow down.
