This add-on is not being updated and it barely works. It will only check one Gmail account, and you can't even force it to check another one. You have to uncheck everything and only check that one, and then it probably won't check it. This used to be such a great little tool, but now it's almost useless.

It does not reset after opening Gmail, and deleting mails....no options other then check interval????

No more than one gmail account. Others does not work.

was working then one day it just stopped

It does not work with the version of firefox quantun, the icon does not appear in the taskbar, it does not work with any gmail account, yahoo, hotmail, does not do anything

no work!

Simply does not work ... too many problems guys ( cookies maybe?!? )

Unfortunately, it doesnt't working with Gmail

it simply doesn't work

It says "this addon could not be installed because it appears to be corrupt".

It's no use.

A pity - the original xnotifier was very handy

Useless, it does not recognize any of my accounts.

Nothing is working properly.

Not detecting any of my Hotmail accounts

Only allows 3 Gmail accounts boooooo

Not detecting any of my Hotmail accounts

в отличие даже от X-notifier lite не подхватил почту ни gmail ни hotmail, а в панели висит с двумя пунктами daashboard и reflesh плюс разделитель под ними.
