Hmm, Folders is not just about reading but also about composing, sorting, archiving, 
there is a whole bunch of stuff that is folder centric. If you look at the sheer 
volume of Folder-related extensions, the need for a separate category is more apparent 
- there are several pages of extensions dealing with the folder tree, sorting emails 
to folders, etc. For the power users, they will probably look at the folder tree and 
ask what can I do to tame (or feed) this monster? They wouldn't necessarily think of 
Message Processing or Display & Editing. I believe Filters is in a similar bracket (as 
it primary task is usually about re-distributing mails into folders).

Also Composing and Reading Mail are 2 very different actions, for the user, so I think 
there is big merit for the user if he can choose between these. Composing is the 
"unloved child" from Firefox, and needs innovation badly.

Plus, like the OP said, Fx has 15 categories, and we are down to 11 already.

Yes, see my latest list at


where there are 11 "must have" items, with lots of example addons and 5 items that 
didn't "make the list", including Tags / Chat / Search and Browsing. They simply 
weren't terribly important for mails or didn't have that many extensions to choose from.
