#114 Can't install Mozilla Addons on Ext3 drives

[StehpanKa]

For Ext2fsd 0.50 and 0.51:
On Windows 7 64 bit I can't install Addons into Thunderbird (3.1.12, 6.0.1) and FireFox (3.0.1, 3.6.23, 7.0.1) profiles when the profile files reside on an Ext3 formatted drive.

The older versions of the mozilla products completely fail to install any addon.
The newer ones (Thunderbird 6.0.1 and FireFox 7.0.1) manage to install a very first addon, but the installation of a second one fails. They keep telling me "Addon will be installed after restart of FF/TB".

Other bug reports of that kind are:

Basically Thunderbird and FireFox are not able to copy some files around on the drive. At least it seems so.
How to figure out what exactly goes wrong?

an following posts by Heinz Repp, an idea what is going wrong in ext2fsd 0.51 and why it effects Thunderbird and FireFox:
"Mozilla adds option OpenReparsePoint which makes sense only on NTFS; other file systems should silently ignore it. But ext2ifs throws an error "File not found" when CreateFile is called with this option. I think this is the error reported in the error console as NS_ERROR_FILE_NOT_FOUND. It is thrown when the staged directory should be created but is not."

The "ext2ifs" is a typo in the quoted text from https://bugzilla.mozilla.org/show_bug.cgi?id=683328#c25
