Hi
I made a forum account because I searched about this very topic and found this thread.
I have the software and its really decent no problem with that.
BUT, with the browser guard extension, I am having issues.
I am using latest version of the Firefox browser and MB browser guard version 2.6.27.
It can be any sites really, Reddit, when I had to use the catpcha to sign up to this forum board, and every other websites with login pages !
The only solution I have so far is to manually disable the extension, refresh the page, and then I can login properly.
Ty for your time and let's hope we find the problem because I love the extension.
