[update]
on my second pc this mostly doesn't work at all. the popup opens, but does not load its content (not even a loading symbol is shown).

Very useful addon, that mostly works like a charm.

some minor annoyances though:
- when typing in a tag and a list of suggestions opens, the first entry should be selected so hitting enter will add the tag instead of starting to send all the data (it works this way with tags in the web-version of evernote). currently it's pretty annoying to accidentally submit instead of just adding the tag you wanted
- the evernote dialog is opened inside a new firefox window (as can be seen in the taskbar) instead of a xul-popup

This review is for a previous version of the add-on (5.0.0.177572).
