Limit Active Tabs by igorlogius

Limits the number of active tabs, by unloading older tabs (determined by last
tab activation)

Why should i use this and not "Auto Tab Discard"?
This addon is more lightweight and far easier to use (configure), since it only
has 1 option (the amount of tabs to keep loaded) So all in all for people who
like their addons simple, small and to the point.

Usage/Features:

1. change the max number of active tabs (default is 3) in the preferences
   
2. use the toolbar button to exclude the current or all highlighted tabs from
   unloading
