Can't change email - request malformed

[Mike]

Every time I am trying to change my email on Atlassian ID page I get a screen with message "Oops, you've made a malformed request". How can I change my email?

Me too, please fix it

It seems that this is a browser problem. Using firefox I cannot login at my atlassian account:

"Oops, you've made a malformed request."

Using another browser and everything works fine.

Update the "Oops, you've made a malformed request." error message to a more adequate and useful one.
