I made an account just to post on this thread. It is absolutely crazy that this is still an issue seven months later. It's "in testing" and "a beta," I get it, but Firefox should have been being tested from day one so as to make it a complete non-issue. And if it wasn't, 30-60 days is usually how long it takes for new browser features to migrate from whoever did it first to all the other browsers. I'm now running an extension to pretend to be Chrome so that I can use a version of Evernote on the web that doesn't suck. I really like the new client, but I'm now running extra software in my browser just to make it accessible. And it seems totally fine, by the way! Maybe a little slower than in Chrome, but still way nicer than the old Web client. If you're that worried about it, just default to old version for Firefox and let us turn it on with a warning.
