Rated 5 out of 5 stars

When internal addresses are used more often than external ones, this addon really simplifies addressing. Wrong recipients are avoided, which adds the advertised security.

My only remark is, that I use two-letter acronyms for recipients, which means I need autocompletion starting with just two letters typed in. Since the addon code defines 5 letters as requirement, I have to manually edit the autocomplete.js and fix that for me. An option defining that limit would be desirable.

This review is for a previous version of the add-on (1.7).

Since TB provides no Address Book priorities for auto completion, this addon helps a lot. I send external mails with and internal mails without confirmation now.

Only the autocompletion addon starting after 5 characters is too limited for me, since we use 2 chars as mail address, and I don't want to type the domain name or white spaces. Maybe that limit can be made configurable in the future.
