Bug #67311 Can't submit bugs with Firefox 16.0.1

Description:
If I try to log a bug on bugs.mysql.com with Firefox 16.0.1 on Ubuntu 12.10 then I get this error message: "An error occured when trying to verify your login credentials. Please log out and try again."

I've tried to logout and login again: this doesn't help
I've tried the Chromium browser on the same computer with the same account: this works.
I've tried to update my account and change my password: works, but still can't access bugs.mysql.com
I've tried to remove the cookies for mysql.com and oracle.com: still doesn't work
I've tried firefox in "Private Browsing" mode: still doesn't work

I am able to login on dev.mysql.com
Yesterday I tried to login on planet.mysql.com and that also seemed to fail, but I didn't get an error message.

My first name has a "ë", this could be an issue for some systems.

Thank you for the feedback.

Do you still experience the issue?

It still happens with Firefox 18.0 on Ubuntu.

Login and voting on planet.mysql.com works.

Any action on bugs.mysql.com still results in a "An error occured when trying to verify your login credentials. Please log out and try again." message.

I found the issue. The issue is the "HTTPS Everywhere" 3.1.3 add-on. Disabling the "MySQL" ruleset in the preferences fixes this issue.

Please set the status to "Not a Bug".

The ruleset of the "HTTPS Everywhere" has more issues with MySQL/Oracle sites:

This is the site of https-everywhere:

Maybe Oracle could:
- Give a better error message
- Communicate with EFF about the ruleset
