Edge: I contacted Microsoft months ago telling them I'm interested in getting Universal Bypass on their platform and they didn't even reply. But fear not, they will soon come out with their "Edge 2.0" which will be able to install Chrome extensions from the Chrome Web Store.
Safari: Doesn't support the WebExtensions standard and one Universal Bypass is more than enough for me to maintain.
Pale Moon: Same as Safari, but more in the "we hate everything that's new" kind of way.
