I think that's your opinion. Although I don't think Mozilla handles it poorly simply because it uses tabs (which I hate to use).

I happen to click on one thread at a time, and when I'm finished I either use Alt+Left to go back or click on the back button, or I simply click on the forum link on the top. I click on the link most of the time, because people post here so often that by the time I get to the third thread with new posts, some of the ones I've already read have new posts in them.

The thing is, I fail to see how opening 30 threads at once makes it easier to read the board. I would think that working through them one forum and one thread at a time would be better for keeping track of where you are.

All I can suggest is that you simply use the combination of:
-Shift+Left Click on the link
-Alt+Tab to go back to the forum

Wouldn't that work too?

Can anyone explain in words of one syllable or less how multiple IE windows work?

I'd love to know which words have less than one syllable I also think "poorly" has two syllables
