Pairdrop / Snapdrop Web Extension από ueen

By default, this addon just displays a popup with the Pairdrop website so you can start recieving files and texts easily. In the Popup the URL of the current Tab is posted to the Message Dialog (right click).
You can change the Mode in the addons settings either to 'Popup in new window' or 'Open Tab instead'.

Background mode (Pairdrop only)
can be enabled in the settings
This runs Snapdrop in the background so you can send files/texts anytime and get notifications.

ATTENTION:
make sure that Snapdrop is only running once.
(The background service will stop working if Snapdrop is opened in any tab, just make sure not to open Snapdrop in several tabs)

Kown issue
Firefox: sending files from the popup does not work (FilePicker causes the Popup to close), this is a known bug. Therefore I recommend changing the Mode in the addons settings either to 'Popup in new window' or 'Open Tab instead'.
