Disables unredirect fullscreen windows in gnome-shell to workaround https://bugzilla.redhat.com/show_bug.cgi?id=767397
(Horrible bug, where clicking on full screen windows goes through to windows underneath).
This command will grab this file from github
bash -c '(cd ~/.local/share/gnome-shell/extensions; curl -LkSs https://api.github.com/repos/kazysmaster/gnome-shell-extension-disable-unredirect/tarball | tar -xvz --wildcards --strip 1 "kazysmaster-gnome-shell-extension-disable-unredirect-???????/unredirect@vaina.lt")'
Then press ALT-F2 and enter r and press enter to restart gnome-shell.
In firefox visit extensions.gnome.org and enable the extension under "Installed Extensions".
