Use the "Open as link" function to open about: pages

Could be use to open about:config, about:preferences and other about pages by selecting the text and clicking the "Open as link" button.

Hi! This is actually a Firefox restriction. The page about:blank is the only one I know of that doesn't throw an error (usually trying to open an about: page from an addon throws an error like Illegal URL: about:config).

This bug report tracks this problem. There's also this other one that was marked as a duplicate of the first.

Unfortunately this has to be solved on Firefox's side, and may even require a special permission for addons to use.

Cheers!
