I’m confused what problem you are having. Are you saying that,even though you never log out of iGoogle, if you close Firefox and start it again, you won’t be logged in?
If so, yeah, that’s likely a cookie problem. Cookies are little bits of data that a website saves to your hard drive. That way, when you visit the site again, it will remember what you have done. You can see how this could be beneficial.
When you login to iGoogle, it saves your username and password in a cookie. When you log out, it deletes that cookie. However if the cookie is messed up, this may not happen. Your solution is to delete those cookies.
Now for the good part: how to do it. Tools > Options > Privacy Cookies > Show cookies. Search for Google, and delete all the cookies that show up.
Or the more spelled out version:
[ul][li]Click Tools on the menu bar. Click Options (at the bottom of the menu)[/li][li]Click the Privacy tab, then click the Show Cookies button (in the middle).[/li][li]In the search box, type google.[/li][li]After a bit, you’ll see a bunch of cookies in the box below. Select them all.[/li](Click the top one, scroll to the bottom, and click the bottom one while holding down Shift)
[li]Click the Remove Cookies button. Close out all the other windows (use the little X button in the upper right hand corner).[/ul][/li]
Now, try going to iGoogle, log in, and then close Firefox. After a bit, start it again, and see if you are automatically logged in. If not, you can try this Greasemonkey script. If you haven’t already, you’ll need to install Greasemonkey first, and restart Firefox.
Heck, if you’re pressed for time, just do that last thing first.
