Man, I have been so patient with Evernote. I have used it to organize research, and esp. to clip web articles, and each iteration gets worse and worse (and it was never very good in Firefox, but at least it worked). Seriously, Firefox users, don't bother with this plugin. I have a lot of privacy add-ons, like NoScript and Ublock, so perhaps one of these is interfering, in spite of the fact that I've tried to whitelist Evernote in every one of them. But still. I shouldn't have to do that -- most Firefox users have a strong dislike of cookies and automatic scripting etc. and prefer to opt-in rather than opt-out. If Evernote cared at all about Firefox users, it would be apparent by now. They don't. Trying to login results in a blank screen in the popup window everytime, in spite of numerous complaints. I'm very sad to say -- Evernote, which was once such a brilliant app, is dead in the water. Trying to find out what to use instead, and how to migrate nearly a decade of notes. Way to run a great idea into the ground.
