We have very different experiences in that case.

Once I go past ~100 open tabs on Firefox, on a 16GB RAM Linux laptop, my whole system freezes. I experienced these issues as late as in June, so it doesn't appear to have been recently fixed either. Note that I do use uBlock Origin so it doesn't just buckle under from ads, but I also make heavy use of Container Tabs, which may also be a factor.

Luckily, the extension "Auto Tab Discard" solved these issues for me.

You can go to about:performance and see which tab is problematic.

Thanks for the tip! I currently don't have many tabs open, but was surprised to see every one of my work Office365 tabs (mail, calendar, etc.) at 100+ MB each...

Perhaps the contents of the pages in each tab could account for such differences in resource usage? A tab count is a very very rough measure. A JavaScript heavy page can have a massive footprint compared to a simple content page.

This looks like a useful extension to me (I'd even love if this was a native FF feature). But I'm noticing it has full access to web pages. Does anyone know how Richard Neomy deals with this data?
