Selected and installed the Skype Web FF Add-on to my installed Firefox version 91.0 for Linux Mint, 32-bit. However, after the installation was complete, there is not an icon showing or displayed in the menu bar to access, initiate and execute the Add-on. Thus, am unable to use this Add-on. Have also written an issue on the Add-on project page within GitLib which this Skype Web FF Add-on shows in their description and settings page within Firefox.

Anyone who knows how to get this Add-on icon to appear, display and give me access to execute is much appreciated.
