Well, I only from time to time have problems when using Firefox with the popups. Most of the times not.
And best feature of FirefoX: Open in new tab in background when clicked with the middle mouse button.
it really makes it easier to read such forums like FT.
Read the article and press ctrl-w and you are to the next tab.

btw there are tools for the IE which will always open up the new windows in a maximized window as well as it helps to press down the shift key to open up a new window with what you like to read. Of couse still not as comfortable as Firefox.
