Good workaround Rated 4 out of 5 stars
I didn't agree with the decision to remove the "Properties" code from Firefox so your extension is welcome.
@Artem Tashkinov - The official Extended Link Properties extension hadn't been updated since Firefox 2.0. There is a modded version maintained by Mozilla Russia community that works fine with "Element Properties" (and with Firefox 3.7 and with Seamonkey 2.0).
