Just an FYI:

Bug 971598 - (self-xss) [meta] Mitigate "Self-XSS" social engineering attacks


Note that NoScript long ago, by default, "Disabled execution of javascript: and data: URLs typed or pasted in the address bar (noscript.allowURLBarJS preference)".

I can't see any details at all on that bug?

True religion, which dares to acknowledge death and challenge the way we live, is an attempt to wake up.

Read a similar thread a while back about Mozilla trying to completely stop javascript: URLs from doing anything when typed in or pasted...
Does any of this mean that people who actually *can* vet javascript: URLs for ourselves won't be able to execute even harmless javascript from the URL bar? If so, any workarounds?
*Always* check the changelogs BEFORE updating that important software!

It has already been disabled long ago.
The work around is using NoScript and turning the preference on, which causes NoScript to emulate URL bar JS just like it does for bookmarklets on non-whitelisted websites.
