Text selection in slickgrid

I have set 'enableTextSelectionOnCells' option to true to select text in slickgrid but I can only select text in IE and chrome but not in firefox. I know this is bug in slickgrid and it had been fixed in slickgrid 2.2 but I am using slickgrid V2.1 and don't want to upgrade to V2.2. Is there any way...
