After the last update on my desktop browser, my password was requested in order to "install a new helper tool." But it isn't accepting my password, even after I double checked what it was. And there's no Change Password link.

Since I can still access the Firefox browser on my iPhone, I thought of I'd change my password there and sync, but the new password isn't accepted either. Once a password isn't accepted, pressing cancel closes the app and it can't be reopened without a Force Quit first.

And 'round and 'round I go. How do I regain access to my desktop browser?

Thanks.
