When I click Tools and go to Extensions Manager, it has a long list of extensions with a lock symbol on them. As most are totally useless to me, I wanted to removed them - but cannot find out how to unlock them.
What do I do?
As far as I can see from my extensions, the ones with the lock are selected during installation. The ones without a lock I added later.
All of these extensions are automatically included in the installation of a new version of LibO.
Therefore you need to make a customized installation and remove what you don’t want to have.
