Yeah, I would. In English what's going on is that
Your browser loaded CA fine. CA asked the server to download the application feed and also asked it what Categories (Backup, Cloud, etc) are present in the feed.
The server would have responded with "Backup", "Cloud", etc
Your addon decided to change that message being received from the server and told CA that the categories were actually the source code of part of unRaid's GUI ( and not even the source code of CA )
I'm not into the whole mining / crypto currency thing, but on face value any add on that's intercepting messages between javascript running on your browser (CA) and your server (unRaid) and changing them would be something to avoid at all costs as it would be a HUGE security risk. (Hope you haven't logged into your Bank's website recently). Incidentally, the message that your server would have sent back to CA with the categories isn't even present in there at all...
EDIT: In your particular case, the server did return the category list correctly. It was when the autocomplete entries were being populated by the server and then returned back to CA is when your addon decided to intercept and change the message. Net result is the same.
