Description of problem: After updating after the bulk recompile this morning, I found that Firefox was practically unusable with extremely strange layout behavior. In particular, many elements have large quantities of whitespace around them. In addition, text on some pages is several orders of magnitude too large. Version-Release number of selected component (if applicable): firefox-3.1-0.7.beta2.fc11.x86_64
Created attachment 333666 [details] A screenshot of the described behavior
Created attachment 333667 [details] Another screenshot
Moving my ~/.mozilla folder out of the way makes no difference.
Also, xulrunner-1.9.1-0.9.beta2.fc11.x86_64
see bug 487844 Perhaps downgrading nspr would fix it for you.
Reverting to the following doesn't fix the issue, firefox-3.1-0.6.beta2.fc11.x86_64.rpm xulrunner-1.9.1-0.7.beta2.fc11.x86_64.rpm
Indeed, revert nspr to the following fixes the issue, nspr-4.7.3-2.fc10.x86_64.rpm
