MIT ruleset is broken (and caused UI crashes in FF 16!)
I am using FFx Nightly (16.0a1) and HTTPS Everywhere, in which I have disabled the rule for MIT. I have the following bookmark: http://mitpress.mit.edu/sicp/
When I try to load it, the address becomes !https://mitpress$3.mit.edu/sicp/ and FFx says there was a problem loading the page. This happens with both HTTPS Everywhere 2.1 and 3.0b5, and on both Windows and Linux.
The Troubleshooting Information from my Firefox install is available here: http://pastebin.com/q8ssEbGq
I will be monitoring this ticket; please ask questions if any.
