Status: RESOLVED DUPLICATE of bug 421828

(Firefox :: General, defect)

If I attempt to view the cache-entry page of a large disk-cache entry(Youtube video file for example), Firefox will lock up. 



Reproducible: Always

Steps to Reproduce:
1. Load up a page with a large file on it(Youtube videos are good for this).
2. Go to about:cache, go to the disk cache, and find the file(it should be a few megs in size at least).
3. Attempt to get more info by clicking on it - Firefox will then lock up.
Actual Results:  
Firefox locked up.

Expected Results:  
Page should load as expected - I think the way to fix this bug is to either:
A. Remove the hex-view portion of the page(But this would limit functionality).
B. Show only the first X KB of the file(The limit, X, would have to be chosen so it would not slow down the browser, yet would show enough to be useful.)
or C. Do not show the hex-view portion of the page if the file is above a given size.

It crashes with the default theme. No special configuration needed.
