Instead of trying to quickly click the link, it's easier to just turn JS off and refresh GMail. You'll be prompted to either turn JS on or switch to Basic HTML. (You can make it the default after that, as described.)

I did this a while back, and the only real issue I've had with it is that there doesn't seem to be an equivalent to the "Check mail now" action for imported email accounts. (The 'refresh' link annoyingly does not trigger this action.)
