Looks like those of you already using the NoScript Firefox add-on, you do not need another add-on to enable/force SSL when it’s available.
Fortunately NoScript, for more than two years now, has also allowed us to manually select the web sites which we want to browse via HTTPS only, by adding them in the NoScript Options|Advanced|HTTPS panel. Of course not all the web sites like to have HTTPS pushed down their throats, so you should pick only those already supporting HTTPS, and still may expect a tiny few of them to misbehave. However your online banking, your webmailaddons.mozilla.org are probably great candidates to be added in NoScript’s “force HTTPS” list right now and the aforementioned addons.mozilla.org are probably great candidates to be added in NoScript’s “force HTTPS” list right now.
