Otimo

Keeps taking you to a vodeo that has being watched. can not get out of that page.

Works great, especially the option to let YT use a higher resolution. Keep updating please.

Working great, and from options you can enable it function a way that you can change to lower quality also, without that checkbox enabled, it changes the quality back to better (if you are setup it like that).

Works great and it does not require to "access-your-data-for-all-websites", which is as follows:

https://support.mozilla.org/en-US/kb/permission-request-messages-firefox-extensions#w_access-your-data-for-all-websites

The extension can read the content of any web page you visit as well as data you enter into those web pages, such as usernames and passwords.
