So I love this add-on HOWEVER. . . and it is a big however. . . If breaks functionality for Facebook for me. When I have it turned on I can no longer hit enter to respond to comments or even to hit enter to send in messenger. It also breaks the notifications menu on facebook to. Nothing loads and it stays blank.

Situation. (with the addon NOT in use but enabled.)
I type a post and then CLICK post on my profile. - That works.
I then go and click comment on that post (or any post) and type my comment in. After I type it in when I HIT ENTER to send it. . . . it never goes. It shifts down farther and the original Font image pops up with my message overlayed on it. Again, the "Aa" that is in the area where you type BEFORE you actually type anything pops back and my text is on top.
This would be 5 stars for me if I didn't have to disable it for Facebook functionality. Please fix the bug when you get a chance.
