Lately, I was having this problem with Gmail site. I’m not sure if it was my system only or browser itself in general. But I have encountered this problem twice so far. It happened once when I was using Firefox 2 and one more time couple of days ago in Firefox 3.

There seems to be a problem with Gmail Logging process in Firefox. Again, I’m not sure if it was only my system but I remember reading it some where else as well. I’ll put it that other source if I find it.

What is the problem?

When you enter your username and password at gmail’s main page, it will not let you access your mail index page where you can browse your mails. If you type your information correct, it will recognize your username but not your password. It won’t tell you it’s wrong. When you enter it wrong, it will tell you that it doesn’t match.

You know that information is correct but Gmail simply won’t accept your password and it will keep asking you to re-enter. To make it more clear; lets say that you are logged in and browsing your emails, when you want to use another service of google, it will ask you to re-enter your password just to make sure but not your user name. So this happens after your first correct try. It will ask for your password but it won’t accept it even though you know it’s the correct information.

What can you do to fix it?

This never happened in other browsers or at least the ones that I used. Before I list couple of ways that I think it might be able fix your problem. In firefox 2, nothing in this list worked for me, it just started working again. I don’t know how. I was able to fix it by clearing cache and cookies then restarting firefox from the menu in firefox 3.

• Before you do anything with Firefox, Restart your browser then restart your computer.This might just work if it’s anything with your system.
• Re-installation of Firefox after uninstalling the one you have.
• Disabling recent plugins
• Clearing Private Data (Ctrl+Shift+Del)- Cookies and cache should be enough.

One more time, this is a problem I encountered two times already, Maybe It was my system only,  I posted this to make it easy for others who might be having this same problem.
