Recently Bhikkhu Pesala published his Cankama font in the Gallery.
I decided to try to access the ligatures using Mozilla Firefox.
So, I prepared a file opentestCankama.htm and tried the test.
Here is the text of a later version of that file. A later version because the original was copied from a test designed for my 10000 Q font as used in the following post and just the font name changed, so I later altered opentestCankama.htm so as to try the ligature set of the Cankama font.
Here is a transcript of the opentestCankama.htm file.

I noticed that Firefox 3.0.8 displayed some of the ligatures but not others.
For example, fi yes, ct no.
Upon reflection I realized that maybe Bhikkhu Pesala had encoded fi and some others as mandatory ligatures and had encoded ct and some others as discretionary ligatures. This is certainly a reasonable thing to do, Bhikkhu Pesala mentioned InDesign, not Firefox!
This post is to ask if there is any way to ask Firefox 3.0.8 to display discretionary ligatures, such as by changing the text-rendering: command to say something as well as, or instead of, optimizeLegibility.
An interesting factor is that Bhikkhu Pesala also allows Private Use Area code point access to the ligatures. I have managed to have Firefox 3.0.8 display the word actually using the ct ligature by noting that the ct ligature is mapped to U+EEC5, calculating that the decimal equivalent of the hexadecimal value EEC5 is 61125 and then adding the following to a copy of the html file.

However, it would be nice if one can ask Firefox 3.0.8 to switch on discretionary ligatures.
