I made a clean Firefox profile and installed and enabled everything in the selection except the Firebug addons and the HTML validator, which does not support Linux. That is, 47 extensions in total. The machine is an old box from 2004 with an AMD64 3000+ processor and 2 gigabytes of RAM, running Debian Sid 64bit. In this old box, with all 47 extensions enabled, Firefox starts in less than 5 seconds and takes about 175 MB of memory.
But even if installing 47 extensions brought Firefox to a halt, why would you need to install all of them? This is simply a collection of recommended extensions, not a set that no developer can do without.
