Timestamp Decoder от noir04

Will decode unix timestamps into a human readable format

To decode a timestamp:
Highlight/select a timestamp
Right click on the selection
The decoded timestamp is shown directly in the context menu
Select "Decode timestamp: xxxxx" to get an alert with the timestamp
The add-on tries to detect if the selected timestamp is with or without milliseconds
If it guesses wrong, keep CTRL pressed while rightclicking to reverse the guess

On some pages I'm unable to use an alert, so I've resorted to using a notification, until I figure out how to do it on those pages with an alert, if possible
