I just played around with bookmarklets for a little while now, so I hope this question isn't too dumb.
My goal is to open about:profiles (Firefox V93.0) via a bookmark in a new tab. Opening a regular URL via a bookmarklet in a new tab/window is fairly straight forward using the window.open-function:
javascript:(function(){ window.open("https://somewebsite");})();
Unfortunately this does not work for the about:-URI scheme, I tried to research how to get around this problem, but so far I had no luck. Any help, hints or ideas would be greatly appreciated.
Note: What I also found out is that the otherwise working website-bookmarklet javascript:(function(){ window.open("https://somewebsite");})(); won't work when I use it's bookmark while the tab I'm on displays any config:-page. Currently I'm thinking since URLs are a subset of URIs the config:-pages might not work with the window.open-function, but so far this is just a guess.
