1) Introduce multithread load and portable feature ( set Portable=1 in tmemutil.ini to enable the portable feature )
2) Implement config.trim_on_minimize on Vista+ OS again, but set it to false by default
3) Provide a tmemutil alternative open source module, whose source code is hosted in https://bitbucket.org/xunxun/tmemutil-3rd ( initial upstream source code comes from https://code.google.com/p/libportable/source/browse/ ). My tmemutil-3rd may not be synchronized updating with libportable, if you want to use latest libportable, you can download http://sourceforge.net/projects/libportable/files/Tools/portable_bin.7z/download , and rename portable32.dll or portable64.dll to tmemutil.dll

Build Method Improvement
BetterPGOAbout System Clock Tweak Experimental Feature
System Clock Rate ( abbreviated as SCR below ) Tweak
Provide some about:config options to modify SCR at startup
1) pcxfirefox.scr.enabled : The option control whether to modify SCR, whose default value is true ( Enabled SCR modifying at startup ).
2) pcxfirefox.scr.always : The option control whether to modify SCR if you use Battery Power, whose default value is false ( If you use Battery Power, set scr.always to false wont modify SCR, if you set it true, that will ignore Power type detect. )
pcxfirefox.scr.timer : The option provides Battery Power detecting period ( unit is second ), when reaching this time, detecing your Power Type again to do the behavior depending on pcxfirefox.scr.always
About SmatRAM Experimental Feature
Control your present RAM
Provide some about:config options related with SmartRAM at startup
1) pcxfirefox.memory.firefox.smart : The option controls whether to enable SmartRAM feature, whose default value is true ( Enabled SmartRAM at startup ).
2) pcxfirefox.memory.firefox.smart.dynamic : The option controls different memory trim methods, whose default value is true, when it is true, then pcxfirefox.memory.firefox.smart.dynamic.min and pcxfirefox.memory.firefox.smart.dynamic.ratio is valid.
pcxfirefox.memory.firefox.smart.dynamic.min : The option controls SmartRAM dynamic method's minimized memory you want, whose default value is 128 MB.
pcxfirefox.memory.firefox.smart.dynamic.ratio : The option controls SmartRAM dynamic method's the memory ratio you want, whose default value is 80, which means when hitting SmartRAM dynamic method event, the memory will be released to the 80% of the firefox.exe's present memory.
3) pcxfirefox.memory.firefox.smart.keep : The option controls SmartRAM keep method's memory size, whose default value is 512 MB, which meanswhen hitting SmartRAM event, the memory will be released to 512 MB. When pcxfirefox.memory.firefox.smart.dynamic is false, the option is valid.
4) pcxfirefox.memory.firefox.smart.timer : The option provides SmartRAM event period ( unit is second ), whose default value is 3600 seconds.
CAUTION: dont't set pcxfirefox.memory.firefox.smart.dynamic.ratio, pcxfirefox.memory.firefox.smart.keep, and pcxfirefox.memory.firefox.smart.timer to a very small value, if you really want a small value, please use them at your own risk ( which will greatly increased your OS's I/O pressure )!
