Comment 15 for bug 20765

If you middle click the link on a page it opens the link in a new tab. The page
begins to load in the background. At one point firefox hangs for 3-5 seconds and
then resumes. I think this is probably happening when the page stops downloading
and it starts rendering, but I have no way to confirm this. There is a noticable
lag and If I am scrolling through a large portion of text all of a sudden the
scroll bar stops scrolling. It still receives input though, and when firefox
resumes it scrolls really fast to where it would have been if it was acting
normally. (does that last part make sense?)

this is with Hoary. and firefox v1.0.6
