Add-ons • Re: Working on a Greasemonkey fork for Pale Moon

With XUL, every bit of your extension UI is loaded along with the browser (and may increase startup time somewhat depending on how many such extensions are installed) and I don't see having to restart the browser after an extension install or update as the end of the world*

Well, no, not the end of the world (I wouldn't give up that easily)... but definitely one of those things that make promoting our chosen technology more of an uphill battle and which counts as a mark against us if we're comparing a WebExtension to an XUL extension head-to-head.
