Sooo time saving.
Hence life saving.
Not among the best, but no.1 add on needed by any effective individual.

Excellent & easy to use

I really don't appreciate the "surprise upgrades". I'd like a chance (more than 30 seconds) to consider and ask how it would actually change user experience.
As a matter of fact, not long after ultimate pushed until i yielded, I suddenly find I have to sign in and out of things I used to be able to reach with a single click.
I also don't know if it might have been your service, coincidental with me making some other mistake that now is requiring a password to be added to just about any request to see, eg: on google, on facebook, etc.
I just want to find out how - or if it's possible - to toggle the "security" feature and escape the need for 17 new passwords.

this works on youtube for me

Great add on for Firefox
