more convenient than Https Everywhere

Good

خیلی عالی

Does not work, period. I use Thunderbird, another Mozilla property (still, at least in name if an unwanted bastard child) to manage RSS feeds, and there is one site with a feed that insists on delivering HTTP links in the feed rather than HTTPS. When I click on those HTTP links in the header of the feeds in Thunderbird, Firefox now refuses to open them, so I needed something to correct the site's carelessness. Smart HTTPS claims to do that but it doesn't: the links when injected into Firefox still aren't converted and still fail.

Not working, is not saving configurations.

edit: I am once craving for this add-ons everytime setting up a browser, now its main functionality which is finding a https version of the website and change into it, while ready to fallback when it found no https version, already implemented in all major internet browser.
