Status: RESOLVED WORKSFORME

(Firefox :: General, defect)

Description

[anonymous]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050511 Firefox/1.0.4
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050511 Firefox/1.0.4

Program seems to have problems loading large (400x400x250) animated GIFs.  I
have tested several which were created from different sources with different GIF
creation programs.  All test OK in MSIE and Opera. 

Problem is consistently reproducable in Linux (Fedora) with Firefix 1.0.4 and
also on Windows NT 4.0 sp6 (not connected to the Internet) with Mozilla 1.7b
Gecko/20040316.


Reproducible: Always

Steps to Reproduce:
1. Load a large animated GIF
2. Wait
3. Program uses up system resources and crashes

Actual Results:  
The program loads the image very slowly, using lots of RAM in Windows and using
lots of swap in Linux.  It plays frames sporatically until it runs out of system
resources, at which time the application crashes.  

Expected Results:  
Load and play the image.  Image does work in Opera and MSIE.

Application did not have an error message, it just terminated.

Reporter, can you test with Deep Park Alpha 1 (Alpha 2 will be available
real-soon-now) ? A lot of code has been changed in this area.

since this bug appears to be filed by someone anonymous who we can not respond
to, close as INVALID?

Not only is the reporter anonymous, but he/she has apparently shared his/her
bugzilla account information on http://bugmenot.com.


Anyway. I have created an animated .gif -
http://mightymu.net/mozilla/test-anim-1.gif
It's 400px X 400px X 253 frames, file size is ~2.6Mb. I've had it running now
for about 20 minutes, on Alpha 2 (20050721), and Firefox is still completely
responsive. Resolving WORKSFORME.
