Can you find any way to reliably reproduce this? 

Is it possible you have some other program on your computer (adware or simliar)
that could be the problem? Try scanning it with ad-aware
( if you haven't recently.

No, I don't have ad ware (I used lavasoft Ad-ware 6). This has happened again
today (over 100 windows opened) and I had to press Ctrl+Alt+Del to stop firefox.
The site was -- no ads there at all!
What extensions do you have installed? Particularly, do you have any concerning
tabs? If so, try a profile without any extensions installed, if you don't have
them installed globally. How often does this happen?

While visiting some crack sites, I got vague xpi installation popups I didn't trust.
Did you accept something of a sort?

I've never seen this until today...running SuSE 9 Mozilla 1.7.0.  I was loading and the site was very slow to load, so while the page
was still trying to load, I clicked or right-clicked in the page, and all the
sudden new mozilla windows started opening like crazy.  I finally got it stopped
after about 50 windows were opened up.

No extensions installed.

I could not reproduce.  Must be a very rare sequence of events to produce this

Another thought, has heavy javascript and flash.  I'm
not sure if I clicked a js or flash link, but it appeared that neither the flash
or js stuff was fully downloaded and working when I clicked.  Perhaps that might
help looking into this?
