 Replying to [ticket:26548 cypherpunks]:
 > I compared the behavior between 8.0a8 and 8.0a9:
 >
 > * Open 8.0a8, and check the "Block all unencrypted requests" in the
 HTTPS-E popup.
 >
 > * Go to a mixedcontent website (go to the github repository efforg
 /https-everywhere then search for mixedcontent and find recent edited one,
 here's an example of such a site
 >
 > * So open that site up while your browser console is opened, you can see
 that HTTPS-E injects an upgrade-insecure-requests header and everything is
 going through HTTPS now including scripts and css etc.
 >
 > ----------------
 >
 > * Open 8.0a9, and check the "Block all unencrypted requests" in the
 HTTPS-E popup.
 >
 > * Go to the previously mentioned site.
 >
 > * There doesn't appear to be any injection of upgrade-insecure-requests
 header, css broken etc as a result.

 This doesn't affect Firefox Nightly 63a1.
