Explain between X-notifier's & Gmail's multiple login

Forums:

X-notifier's multiple login (used in XN-Firefox/SeaMonkey/Thunderbird).

  • login all accounts at once (FF/SM/TB checking all accounts at the same time.)
  • no limit to the number of accounts.

Gmail's multiple login (used in XN-Chrome/Safari/Opera).

  • login accounts one by one (CH/SF/OP not checking all accounts at the same time,
    instead of having to check one at a time sequentially.)
  • up to 10 accounts

FYI: Regard to Thunderbird
You can get multiple notifications for Gmail on Thunderbird.
But you can open only one Gmail account at a time.

Reason behind (history)
X-Notifier's own multiple login method.
X-notifier was developed, before Gmail's multiple login is out.
X-notifier's method is faster and has no limit to the number of multiple login accounts.

X-notifier for Chrome/Safari/Opera uses Gmail's multiple login,
because Chrome/Safari/Opera do not have APIs for X-Notifier's own multiple login method.

Comments about Gmail
Gmail's multiple login could be implemented in XN-Firefox...
but it is inefficient and would require huge internal programming changes.
