Rated 5 out of 5 stars

Excellent very handy add-on.

Missed an abilities to
1) change a protocol
2) delete some parts *in the middle* of url (like a subdomain part do at the beginning) and selectively discard http request *parts* instead of entire request

Also in the protocol-dropdown some about: urls are absent in the list while some in the FF itself.

Anyway -- it's excellent
