Gitextensions: Mono doesn't have installed WebBrowser

[HappyNTH]

I'm trying to use GitExtensions through Mono, as I have been instructed through the manual. However, when I try to like to my Github, it says Mono doesn't have installed WebBrowser in the GitExtensions client, and opens a blank window. I get the error libgluezilla not found. To have webbrowser support, you need libgluezilla installed in the Terminal. Please help!

I'm using Mac, so this is not a possibility. I manually entered an OAuth key, and now it shows my personal repositories. However, when I try to clone anything at all, I get the error:
Permission denied (public key)
fatal: Could not read from remote repository

Please make sure you have the correct access rights and the repository exists

I am certain of both of these, and the OAuth has full rights.

I get this same error on Linux Mint 18.2 and I do have libgluezilla installed:

matt@dell-xps ~/ $ cat `which gitext`
#!/bin/bash
mono ~/.local/opt/GitExtensions/GitExtensions.exe "$@" &
matt@dell-xps ~/ $ gitext 

    # in app use Menu: Plugins >> Github

matt@dell-xps ~/ $ libgluezilla not found. To have webbrowser support, you need libgluezilla installed

matt@dell-xps ~/ $ apt-cache search libgluezilla
