update

My application installs my Firefox add-on (by copying an my.xpi to [FF_inst_dir]\extensions). This application interact with my FF add-on. This application periodically has updates (.xpi with new version). When my application is updating it does next:

Remove folder and content [FF_inst_dir]\extensions\MyExtension
Copy new my.xpi to [FF_inst_dir]\extensions

However, when I restart FF I see:

FF ask me about install add-on. I agree.
FF remove my.xpi (it's ok)
FF remove folder and content [FF_inst_dir]\extensions\MyExtension I think that FF try to remove old plugin.

Thus, I havn't installed plugin.

How it can be installed correct?
