broke almost all the basic pages. not worth it

Worked almost fine for me... But somehow I prevented some Pages to load the Login windows (iframes?)
even whitelist the website did not help. That's why I had to remove this extenstion. Everything else worked fine, but the block me from using my mails made it unusable.

Does what it says and does it well.

would keep if it didnt open a window every time you install it

Occasionally have to turn it off to use or find some features on some sites but overall a real game changer and I rarely turn it off
