CloseReview for British English Dictionary by Nicely
Rated 3 out of 5 stars
I'm also having the same problem with this add-on disabling every day with compatibility. Update it and it works again...until the next day. Occurs on both Thunderbird 3.0.3 and Firefox 3.6. The 'words.xpi' tip makes no difference.
This review is for a previous version of the add-on (1.19).To create your own collections, you must have a Mozilla Add-ons account.
