Not able to sign in Rated 2 out of 5 stars

I do not seem able to sign into the web clipper for Evernote. After I enter my details it tells me it's loading and then I get a blank box, no matter what length of time I leave it, it stays blank. I tried click on the page and then when I click again on the extension I have to go through all that again to see a blank box. The major reason I got Evernote was to use this extension.

Support for Stable only

Hi Mike,
We officially support Firefox stable only. However the sign in issue that you mention may be related to a server side bug that was fixed yesterday.

Please try:
1) Sign in with your full email address instead of only username.
2) Not use any capitalized letters in the username field.

Let me know how it works out.
