I personally know somebody who is currently running a Firefox with 3,000+ (yes, you read that right) tabs as part of their day to day workflow. Firefox just unloads tabs that weren't used for long and cause high memory pressure which is very neat feature for tab addicts.

This describes me. I currently have 3467 tabs. Firefox is the only browser that can handle this.

6400+ currently. Firefox does not break a sweat.

Forget Firefox, my brain can't handle more than 10 tabs 0_0
