Since Firefox 18.0 or 18.0.1 (current) on the Mac, the Evernote clipper no longer works, either the 5.4.1 regular version or the 5.5 beta. The dropdown begins to appear but with only the circular progress indicator, which spins forever. The clipper works in Chrome.
I've emptied the cache, removed all Evernote cookies, and reinstalled the clipper a couple of times. No luck. I'm about to migrate to Chrome as my primary browser, but would prefer to stick with Firefox if I can get this fixed. Mac OS: 1.8.2. Clipping to the web version of Evernote.
