I'm using firefox 11 on Ubuntu.

For some strange reason, Firefox won't save my google cookies between browser restarts. I have to log in to gmail every time I restart my browser, even if I click on the check box that tells Google to remember me.

The strange thing is that Firefox does actually store some gmail cookies when I log in. It's just that those cookies disappear after restarting Firefox.

The especially strange thing is that this only seems to happen with *.google.com url's. I haven't noticed this problem with any other site that I use.

Please note that I tried to see if this was a plugin-related problem. I therefore started Firefox in safe mode and turned off all plugins. I then logged into Gmail and told it to remember me. I then shut down Firefox and started it the same way in safe mode. I got the same bad results.

Has anyone else ever seen anything like this before? Is there a reason that Firefox seems to be blacklisting Google cookies?
