Plugins section on main website.
This is a proposal for the future (or the present, if anyone's ready to say this can work now).
Whether the TBB is based on Firefox or Chromium, it will have the ability for extensions/addons to be installed.
There are some of these which are known to interface well with the bundle; it would be excellent if there were a section of the site that at least listed compatible or vetted addons, or possibly even hosted them. Flock always had it's own extension page, K-Meleon has always had its own extension page as well - not all addons have to come from Mozilla. At the very least, it would be nice if there were a page devoted to a list of addons that can be considered harmless?
I'm aware that there are already more projects than there are people to spearhead and run them; this is just to bookmark the idea and create a starting point when the potential materializes.
