I am using Webclipper Version: 7.12.5.42-bb2fa76 with Firefox 76. Both updated. Webclipper does load (for a moment the "webclipper loading" pop up shows) then: nothing.
Did get into the copy log which give the message:
2020\5\5 22:24:45 WRN DB set value error: InvalidStateError A mutation operation was attempted on a database that did not allow mutations.
Please advise
