Firefox 28 doesn’t work properly

[dNx]

Hey tete,

I updated my Firefox from 26 directly to 28, but it doesn't recognize my profile specified in the tmemutil.ini

content of the ini:

[General]
Portable=1
PortableDataPath=path/toProfile

Any ideas? I really need my profile. :/

Hi dNx, this problem is my mistake.
I have uploaded the fixed version. Sorry for your inconvenience.

Wow, that was fast.

Thanks a lot! 😉

Tete, what did you use to build 28? Did you move to VS2013?

Hi Ryan, I used VS2013 to make my build of Firefox 28.0.
I did not apply PGO to it because of the following reason:

Bad news. Beside that, according to SunSpider results the official Fx28 build works faster than yours on my PC.

VC2012 PGO seems to be having the same problem as VC2013 PGO.

What PGO Optimization changes between VC2010 and VC2012?

I think PGO has been improved between VS2013 Update 1 and Update 2 RC.

JavaScript benchmark results of my unofficial builds of Firefox 29.0 (built with VS2013 Update 2 RC):

SunSpider 1.0.2 (repeatCount=30)
-O2: 164.2ms +/- 1.1%
-O2 -GL: 155.1ms +/- 0.9%
-O2 PGO: 144.7ms +/- 0.6%

kraken-1.1 (repeatCount=30)
-O2: 1288.7ms +/- 1.7%
-O2 -GL: 1267.9ms +/- 1.3%
-O2 PGO: 1228.3ms +/- 1.1%
