I just installed YSlow but only to found that only a basic pages gets created - if I try to click any link on the same YSlow report - no action happens
FireFox - 37.0.2
YSlow development is abandoned for a long time now by its original developer. Though in January this year there was a post regarding the most used Firebug 2 extensions including YSlow.
The intent behind that post was to identify the extensions, which should be reimplemented by the Firebug Working Group in the future.
