Cannot install Lansweeper Firefox Extension

[FriendlyGuy]

Hello,

I'm trying to install the Lansweeper Firefox Extension .

The Setup Guide states at Point 4

• Click the cogwheel icon and select Install Add-on From File...

On my Firefox 123.0.1 there is no "Install Add-on From File" it is missing.

How can I install the Add-on?

Hi,

Got the same issue with 123.0.1 (64 bits). Don't find any AD policy block add on installation.

Installation works fine and ask to reload firefox, but can't find the add on. And when i try to install, there is no xpi in the folder browser extension.

Any ideas ?

Regards

Bapt

Hello Erik,

in know the KB.

I found out, that it was a Group Policy which blocked the Addon Installation from File.
