Counter data point: I've had it running with 100+ tabs open for at least 2 months now. Yes, it gets restarted when my phone does - or when I need the resources for something else, or doing updates, but it's working great. Motorola Moto G second gen, running LineageOS...

This has not been my experience. I've been using Firefox for a while now with way too many tabs open and I've not encountered a crash. Or at least not one I remember. It could perhaps be some hardware it doesn't work well with? Or maybe it struggles with certain sites that I happen not to visit?

I hadn't heard of Fenix but it seems I'll have to try that soon.

I haven't used Firefox on Android in 6 months or so but it was pretty stable for me.

I switched to Brave for mobile and it is amazing. Super easy to block scripts and other tracking without hijacking your DNS or requiring ad blockers/pi-holes etc.

Firefox Mobile is being phased out and replaced by Fenix; have you tried that?

Wait what? Can you give me a source or further reading on this?

Here’s one, sorry I did not link before: https://www.zdnet.com/article/mozilla-end-of-firefox-for-and...
