Status: RESOLVED WORKSFORME

(Firefox :: General, defect)

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8) Gecko/20051111 Firefox/1.5

Updated to 1.5 final last night and had immediate problems. Typically, after a couple of minutes of browsing, I will find that clicking a drop down menu results in only a partial outline of the menu appearing (no text). This is accompanied by a failure of mouse scrolling following clicking the scroll wheel (although clicking the scroll wheel gives the correct icon).  Firefox then soon becomes partially or fully unresponsive. 

Reproducible: Sometimes

Steps to Reproduce:
Not sure how to reproduce, but happens regularly after a few minutes browsing. May possibly be related to using mouse scrolling following clicking the mouse wheel. May also be related to highlighting large amounts of text while reading.

Can now reproduce everytime.

1. Go to nytimes.com
2. use mouse button to open an article (any will do) link in a new tab
3. click over to new tab
4. attempt to use mouse scrolling (i.e. scroll by clicking mouse wheel when not on a link, then displacing mouse).
5. Scroll icon will appear, but it will not scroll.
6. Click on "tools" or other drop down menu. 
7. Only the outline will appear
8. Browser becomes increasingly unstable

Not sure why this happens at NYtimes, and not at some other sites, but is likely not NYtimes specific.

WFM. This is probably due to some incompatible extension. Try running Firefox in Firefox safemode (not system safemode):
