As I had discussed with :tn yesterday on IRC, I've done a couple of tests for Pre-beta Sign-Off of this feature, and I can confirm that this fix is verified.
I've tested this feature on Windows 7x64, Ubuntu 13.04 x64 and Mac OSX 8.4, by measuring the memory usage in about:memory while loading the URL mentioned in
Comment 13 on a fixed build (Latest Aurora 26) and on a non fixed build (FF 25RC).
Results
1. Windows 7x64:
a)Latest Aurora 26: Memory usage increased from 150MB to 280-300MB. No hang or freeze encountered.
b)FF 25RC: Memory usage increased from 150MB to 1500MB. I've encountered hangs and then freeze while loading the URL.
2. Ubuntu 13.04 x64:
a)Latest Aurora 26: Memory usage increased from 150MB to 350-400MB. No hang or freeze encountered.
b)FF 25RC: Memory usage increased from 150MB to 1000MB. I've encountered hangs and then freeze while loading the URL.
2. MAC OSX 8.4:
a)Latest Aurora 26: Memory usage increased from 200MB to 350-400MB. No hang or freeze encountered.
b)FF 25RC: Memory usage increased from 150MB to 1350MB. I've encountered a couple of hangs while loading the URL.
I can provide similar results for Latest Nightly 27 as those mentioned above for Latest Aurora 26.
My PC configurations:
1. For Windows & Ubuntu testing: i5 Intel 3.6Ghz, 4GB DDR3.
2. For Mac OSX 8.4 testing: i5 Intel 2.5Ghz, 4GB DDR3.
Builds used for testing:
FF 25RC: BuildID: 20131022215409
Latest Aurora 26: BuildID: 20131024004004
Latest Nightly 26: BuildID: 20131024030204
If there is anything else that is required to be tested for Pre-beta Sign-Off of this feature please let me know, otherwise I will mark this Bug as being Verified.
