Interesting...Mozilla has removed most of the list they had previously published, now limiting it to 9 add-ons.

I take the same approach as app103. Sometimes I install but disable extensions for later use.

A shiny new feature in Firefox 4 offers exactly that.  It's just very few developers are yet to convert their addons to use it. Here's a few that do.
