Not reliable (doesn't work always) Rated 1 out of 5 stars

This extension doesn't work always!I manually enabled Force-SSL for some sites, but extension secured only part of HTTP requests (not all of them). This was verified with proxy server (Fiddler).
I think developers of Force-TLS should do more testing, especially with forms (with non-HTTPS targets), 302 redirects and other non-standard situations.

This review is for a previous version of the add-on (2.0). 

Force-TLS uses a "redirect to https" mechanism that's imperfect, and I'm working to try and fix that for Firefox 3.6 and earlier -- it's not simple.

Firefox 4 and later have much better support for changing non-https connections to https ones, and if you install version 3 of Force-TLS you can have the UI but the add-on will use the far superior built-in HTTPS-forcing features of Firefox 4.

Please email specific issues to and I'll try to fix them!
