Script Summary: Makes addons.mozilla.org only show firefox addons that are compatible with your version of firefox.
The add-on site now has this kind of functionality built in!
You're a Firefox user.
That means you have to love your add-ons.
But maybe not the Firefox add-on site!
half of the add-ons on there aren't compatible with your version of Firefox.
Here is the solution.
onlySeeCompatible - will hide all add-ons on the Firefox add-on website that are not compatible with your version of Firefox.
this can really save time while you're browsing add-ons!
