Update Now version 0.3.2, supports more link styles: module:// and dist:// for CPAN, doc:// for perldoc.perl.org, href:// for odd links on this site, and plain http:// for anything else. It'll try to uyse the actual link text for the less normalized URLs (the latter two). And I've upped the maxVersion to 2.0, though I haven't tried it, I have the impression not much has changed in the Firefox Extension API. Here's for hoping.
Tested for some time now on 2.0 and seems to work like a charm. Thank you!
