I routinely have hundreds of tabs open in Firefox at any given time without crashes on macOS and Linux. The tabs include everything from documentation, Jupyter notebooks, papers, Jira, Reddit, HN, Github, Gitlab, GMail, Google Keep, Todoist, etc. I can't even recall the last time Firefox crashed for me.

Many hundreds of tabs here in FF on Windows and pretty rock solid.

Agreed.

I've got 99 problems with Firefox, but a crash ain't one.

6GB is ample memory if you're not loading tons of tabs. I run Firefox on Raspberry Pi model 1s and while you have to limit yourself to a tab or two and have plenty of patience it does still work.

What doesn't work is trying to compile the browser on the Pi. The build process has some really gigantic source files that cause the compiler to choke.

Just throwing it out there - most software and OS's adapt to fit hardware constraints. I was running 32GB of RAM, and regularly hit 20-24GB of use in my web browser. When I switched to 128GB of RAM and reloaded my session, my web browser expanded its use to 40-44GB and performed a lot better. While Firefox may be working with 6GB, it may work a lot better with 16GB, for example.

The crashes could be some addon or other profile feature interfering with Firefox's stability. I had a profile that I migrated from FF 1.x, and I finally had to put that one to rest...

I don't know if I've experienced a crash in Firefox in years. I would really suggest taking a look at the crash logs and maybe do a checkup on your machine's health.

You should really check if you have bad memory. I've found firefox to be very sensitive to such an issue

Paste a few links from about:crashes here. If you click on them, you might find the associated bug (if it exists).

Firefox should literally never crash. If it does, that's a serious bug (but especially on Windows, not necessarily in Firefox itself).

Fwiw i left Keep a few years ago because they totally fucked the web client. Wouldn’t work for me on either ff or chrome. Had a few thousand notes. Not sure if it’s any better now but that may be a Keep specific thing

I've only got 4 gigs of RAM, and don't think I've seen Firefox crash in years. And I run Jupyter notebooks, browser games, image processing, all sorts of intensive things on it.

Hum... Firefox breaking on some Google site is surprising, but not extremely so.

Maybe corrupted firefox profile? Try running it with a new empty one.
