Comment 25 for bug 610915

In response to comment #12
"(...) and the case where the user wishes to save two different usernames for the same site, that differ only by case."

In bug submitted by me, https://bugzilla.mozilla.org/show_bug.cgi?id=499715 Firefox have to deal with different use case. There is one domain with two different service installations (phpbb forum and MediaWiki site), those are completely separated applications from user point of view (registration is independent). As a result having different passwords for forum and MediaWiki is not an odd user case IMO.

Having multiple accounts that differ only in case, in #499715 example, also is explainable. Why? Because MediaWiki installation by default is creating user logins starting with upper case... So MediaWiki is creating "Alogin" logins.

It wasn't my choose to have similar login with upper case and lower case difference, MediaWiki created upper case login AFAIR.

After upgrading Firefox to 3.5 in this situation (with different passwords set for Forum and Wiki) I had to do this steps to bypass login problems:
1) Login into MediaWiki with other web browser, change password for the same password as on Forum
2) In Firefox3.5 Go to the Preferences/Options Security tab and delete upper case login (Media wiki's one)
3) From now on login to forum and Media Wiki with lower case login
Third step works only because, as i realised today, when I login with "alogin" into MediaWiki it will also work (MediaWiki is redirecting proper "Alogin" to "alogin" which i wasn't aware of...)

Having multiple accounts (with different passwords) that differ only in case is
already full of fail for a multitude of reasons, so I'm not really inclined to
want to support that use-case."

So AFAIR this bug doesn't apply only to the same site, but to the same domain.
