[Tracking Requested - why for this release]: This is a functionality regression in 63 Nightly. I bisected this regression to the following pushlog, which points to disallowInheritPrincipal bug 1466801: https://hg.mozilla.org/integration/mozilla-inbound/pushloghtml?fromchange=9112406a54a2d3806112111620f25267203a992e&tochange=b5e9fdddf12e598962d6282a4b053aa66b7aabda STR: 1. Install a javascript: bookmarklet, such as this Hacker News bookmarklet to submit links to Hacker News, by dragging it to your bookmarks toolbar: https://news.ycombinator.com/bookmarklet.html 2. Click the Hacker News bookmarklet. EXPECTED RESULT: Hacker News' link submission page should be opened. ACTUAL RESULT: Nothing happens.

This bug is a regression from disallowInheritPrincipal bug 1466801.

FWIW, they still work when you execute them using the custom keyword, if any. However, if you try to execute them using the keyword and pressing Alt+Enter to open them in a new tab, they don't work. Open the new tab first, and then execute it using the keyword as a temporary workaround.

Keywords work differently to bookmarks on the toolbar.

Why only the current tab? As far as I can tell, the use case for middle-clicking a javascript bookmarklet on the toolbar is still broken.

> Why only the current tab? As far as I can tell, the use case for middle-clicking a javascript bookmarklet on the toolbar is still broken. From my testing it only is needed when it is applying to the current document rather than creating it's own document. However I will double check tomorrow. Also perhaps we can just use the document principal in this case instead.
