Rated 4 out of 5 stars

"Expression Search" works well, but I wish it integrated with Thunderbird Conversations to really emulate GMail.

But what about "GMailUI"? I used to use this extension to switch to GMail's keyboard shortcuts, yet this functionality seems to have been removed since then? Please restore this functionality, I keep inadvertently marking all my messages as junk!

Đánh giá này là cho một phiên bản trước của tiện ích (0.8.3). 

Compared with original GMailUI 0.6, these features are still missing:

Use 'Y' to archive selected mail to archive folder (use 'a')
Use J/K to move messages up and down, and Ctrl+J to mark a message as junk (conflict with builtin key mapping, use 'f/b' instead)
Key '/' focuses on the quick search bar (use Ctrl+F)

Please try http://kb.mozillazine.org/Keyconfig_extension for change key config.

Sorry for the inconvenience.
