Is there some kind of ‘beforeLinkClick’ event which can be canceled, on certain URLs? Or an option to rewrite the openDefaultBrowser(url) function, which I’m guessing gets called, when you click a link?
The end-goal is to develop a ‘Link-Blocker’ for emails opened in Thunderbird.
I already found out that there is a setting under network.protocol-handler.external-default to completely disable links, which is what I want for most links. Other links I want to whitelist via user-prompt.
