a bit sloppy so far Rated 1 out of 5 stars

The English is not good in the description when the "www.tran" pane/frame is open. The red 'close' cross didn't work. They suggest we let them know our impressions, but don't provide a link; nor was I able to copy/paste the name from the pane. Fvcking flash. I hate it.
So far, I have not tried translating anything; my experience was simply that of opening the pane by accident and not being able to close it again. No reason to doubt the quality of the translation.
While the pane was open, I did change the settings for languages to be translated from. I didn't like the fact that the only languages provided on clicking the arrow were English, German and Other, All other languages were an extra click away, and so greyed-out as to be invisible.
So I've tried it again, and this time hitting the close button left the Tran pane in place and closed my tabs sidebar. Compatibility problem. Regrettably I will have to remove this addon.

This review is for a previous version of the add-on (4.2.1-signed.1-signed). 

Thanks for review

Thank you for your valuable comments. I'll take them into account in the next version.
