You should try Opera as well, it's is the only browser that runs smoothly with many tabs, every other browsers fails with 25+ tabs when it comes to speed and stability. ATM I'm running 50+ tabs with 1.5 GB RAM usage. I want my browser to be open all the time and run smoothly no matter how many tabs I have open, so it can use all the memory it needs, RAM is cheap, 16GB have to be filled with something.
