Open enough tabs and you'd be lucky to keep firefox running for more than a coup...

I have had hundreds of tabs open for many months in the past. The bottleneck is usually the OS crashing rather than firefox.

I have 488 tabs in the session with more than 50 loaded. The running session has 72 processes.

I'm around 1700 tabs with somewhere in the 20s or 30s loaded. It's been a month or more since I restarted firefox.
