Hi there, I have installed the dropbox file link add-on in my Thunderbird mail client (24.6.0.) When attaching a file to an email (Write/Attach/Filelink), Thunderbird prompts me to sign in to my dropbox account to authorize the attached link. A window from within Thunderbird appears, I enter my login details as I would on the dropbox web access then... nothing happens when I hit the sign in button. No response, no error message. I checked multiple times that the dropbox sign in details I use are valid by connecting from their web portal. Has anybody encountered a similar issue when linking dropbox and Thunderbird? If so, I would be grateful to get some help on this one. Thanks, Marc I am running Ubuntu 14.10 Trusty Thar 64 bits
