My browser at work (Chrome) manages it performance wise with no issues. It's only a UI issue. I've tried plugins for vertical tab management and never found one I've liked for any of Chrome/Safari/Firefox. I've also tried built-in tab grouping in several browsers and also never managed to make one stick. They're often too inflexible I think.

Reducing the number of tabs is a good solution, but browsers don't tend to have features for this. Arc does, and I rely on its tab archiving which I think is pretty good.
