Hmm, if I recall I tried that but it didn't work for me.  I just tried
it again, and it didn't, I'm still getting -O2, e.g.:

There's something I didn't try.  In Firefox 2.0, they've changed it to
"Allow pages to choose their own fonts, instead of my selections above".
It works the same way, except it's an opt-out choice now.

I disabled that option, and found that there seem (so far) to be fewer
display glitches than before.  I do still see some though, it seems to
really get tripped up by links more than anything else.

Yes, I used script(1) to generate a log of the build, and grepped it to
confirm what optimizations were used.

Here are my about:buildconfig results:

Thanks for the information, Firefox is less annoying after the settings
change you suggested.
