You get that message if the extension needs to be unpacked to run properly because it want to make changes or save data in its extension folder.
The normal way is to copy the extensions XPI file to its extensions folder without unpacking all files.

Which extension(s) give you that error message?

Hey,

I'm having the exact same issue, except I'm on OSX 10.8.2 and FF 16.0.1.

I can't install any extensions. If I try via Tools -> Add Ons, I get the error "There was an error installing <extension-name>". If I try via the addons.mozilla.org site I get the "can't modify file" error msg.

I have changed extensions.alwaysUnpack to TRUE, but there is no change.

Any help would be greatly appreciated.
