How do I install Filelink on Thunderbird?

I am trying to install filelink_provider_for_box-4-tb. I downloaded without difficulty but Firefox cannot run the program. The error message reads: "This add-on could not be installed because it has not been verified."

Microsoft's Ultra File Opener does not work either.

Box online storage provider is recommended by the Thunderbird help-sheet Filelink for Large Attachments. Could you please help me to install Box and set up Thunderbird Filelink. Alternatively, should I choose another online storage provider?

My operating system is Windows 10 Pro, Firefox is 78.0.2 (32 bit) and Thunderbird is 68.10.0 (32-bit). All three programs are fully up-to-date.

Many thanks

Open Options/Attachments/Outgoing, click Find more providers..., and in the tab that opens, note the FileLink Provider for Box entry at the bottom, click Add to Thunderbird.

sfhowes. Thank you for your prompt and helpful reply. So simple when you look in the right place. For some reason, I could not activate the Box account. However, I realised that WeTransfer is already installed and this meets my requirements.
