Subject: [PATCH] extensionDownloader: Refuse to override system extensions
|
||
|
|
|
||
|
|
The website allows to "update" system extensions by installing the
|
||
|
|
upstream version into the user's home directory.
|
||
|
|
|
||
|
|
Prevent that by refusing to download and install extensions that are
|
||
|
|
already installed system-wide.
