I do that (100+ tabs open at any given time) due to my work (research tends to take up a ton of windows) and because I'm too scatterbrained to focus on a single thing at once, but even then I find that Firefox is really good and arguably better than Chrome. Maybe Chrome has improved since I switched over, but Firefox uses significantly less resources than the Chrome that I remember

I have ~800 tabs open in Firefox, no real issues unless I flip through all of them or Tab Groups shuffles them all around. My desktop until recently was over a decade old and the new one is barely any faster.

I have actually always found Firefox to perform better. Especially compared to the RAM whore, Chrome.

People really got to learn how to use Bookmark All Tabs... properly.

If you're in the middle of something and you got to switch to something else, organize all the tabs to separate windows, and use Bookmark All Tabs... to Saved Sessions folder or whatever you want to name it. This will allow each window to be saved individually. Save it with a date and at topic name, like "20230625 Bread maker" then close the window.

I have a fear of crashing Firefox, restore failing, and losing all my tabs. This fixes most of that.

Using the Bookmark All Tabs... method has help me organize my tabs, makes syncing with devices easier, and has allowed me to keep browsing sessions completely off my mind until I need them again.

You sound like someone that doesn't open 200+ tabs of furry adult imagery on e621 while playing processor intensive games.

I mean... I'm obviously not that person either, but it would be cool to have the RAM to support it or the correct web browser if I was that type of person. But I'm not. But having that capability would be nice (not because I need it).

...I don't look at furry porn.

For years Firefox on Windows had this weird random bug for me where audio just would not work at random times. I tried every fix imaginable. I spent hours crawling the internet trying to find a solution. Couldn't fix it. I've used it on Linux but not on Windows for a few years now; I'm going to be doing a fresh install of Windows on my computer soon, so we'll see if the bug finally disappears then.

Ever since firefox switched to quantum it's been great. I would say it outperforms chromium under typical circumstances.

I've had 5k+ tabs open at some points, because I just don't close any of them, and I often middle click as I want to navigate back to the page I was at. Additionally, a lot of sites break the back button, like collapsing comments re-expanding, or it loads slowly and I wanted to look at it quick. Organization is pretty nice with Tree-Style Tab for Firefox.

Every few months I purge all of my tabs, but for the most part, I just don't care when I have 32 GB of RAM.
