732435 - Firefox creates an empty Extensions directory in %USERPROFILE%\Mozilla

Status: RESOLVED DUPLICATE of bug 2001887

(Toolkit :: Add-ons Manager, defect, P3)

Description

[Mike Kaply [:mkaply]]

When Firefox is started, it creates an empty Extensions directory at

%USERPROFILE%\Mozilla

This is problematic for Firefox builds that are self contained on USB keys.

Firefox should not touch the user's system unnecessarily.

The problem is here:

http://mxr.mozilla.org/mozilla-central/source/toolkit/xre/nsXREDirProvider.cpp#1122

The call to EnsureDirectoryExists

Not sure why we need to create that there. As a workaround I think that if you set extensions.enabledScopes appropriately to ignore system/user directories this code won't actually get called.

Perfect workaround. I meant to have enabledScopes set to exclude the user directory, but I got my math wrong.

Thanks.
