Status: RESOLVED INCOMPLETE

(Core :: General, defect)

Description

[[e-mail]]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:17.0) Gecko/20100101 Firefox/17.0 (Beta/Release)
Build ID: 20131022185104

Steps to reproduce:

1. Open XULRunner Application Browser, open test page "a.html" url in the browser, this test page contains bunch of gif images, after the page had been load completed, the memory will be increase about 200M;
2. Open another test page "b.html" url in the same browser, this test page also contains another bunch of gif images, after the page had been load completed, the memory will increase another 160M;
3. Open the test page "a.html" in the same browser again, after the page had been load completed, the memory will increase another 200M;
4. Open the test page "b.html" in the same browser again, after the page had been load completed, the memory will increase another 160M;
.....


Actual results:

The memory keep increasing and accumulated(200+160+200+160+200+160+...) which will eventually crash the XULRunner Application browser, Firefox also have the same issue, if you navigate between html pages which contains bunch of gif image, the memory never get release, they will be accumulated which will eventually crash Firefox..


Expected results:

As you can see, in the reproduce steps, I only navigate between two html pages, I don't understand why navigate back to test page a from test page b, the memory still increased, this is a regression behavior, since I have tested, in XULRunner 6.0, If I navigate back to test page a which had been load before, the memory won't increased..

I think this is a frustrated regression which have block our produce, since we use XULRunner as embedded browser which used to show gif image as emoticons, however, when user switch between different page with bunch of gif images, the memory will keep increasing which will quickly crash the app.. Could you please fix this regression or could you give me some advices which can workaround(such as preference setting?..)?

due to size limited, I can't upload gif image source, if you want to reproduce, you can find those gif image with animation which can take much memory which can easily reproduce the issue.

Hi reporter,

The testcase you provided in comment 1 only displays some wired symbols on the screen. Can you please provide another test case so I can try to reproduce this issue on my end?

Also, is this still reproducible on your end ? If yes, can you please retest this using latest FF release and latest Nightly build (https://nightly.mozilla.org/) and report back the results ? When doing this, please use a new clean Firefox profile, maybe even safe mode, to eliminate custom settings as a possible cause (https://goo.gl/PNe90E).

Thanks,
Paul.

Hi Paul,
1, We found this bug on Xulrunner 10.6esr, and we have workaround it from other side(not in Xulrunner).
2, This bug cannot be reproduced in recent version of Firefox.
3, If you still wanna reproduce it, you can create 2 html file with lots of large size gif by yourself.
It's pretty easy!

Thanks,
Vincent.
