Running multiple tabs in Firefox has become a common habit for modern web surfers, but to the resource-conscious, it’s a CPU‘s nightmare. Let me demonstrate. Have a go at opening these websites simultaneously then watch them grind your precious clock cycles to oblivion -whether you minimize the application or not! (My record was 87%)
Have no fret though, because there’s an already-popular NoScript extension, that dramatically lowers the load on your processor and lets you browse safer and faster, even if Flash remains enabled. Until Mozilla improves their code, I highly recommend all power users to install it for a better online experience.
Extra: For even more optimization, use optimized builds.
