Rated 3 out of 5 stars
For some unknown reasons, option and stationery button don't show anything when entered. DO you have any ideas?
TB 56.0b6 (32 bits)
It is fallout of this change in Firefox code: https://bugzilla.mozilla.org/show_bug.cgi?id=1383215
Many extension will have to be fixed, but more importantly the TB itself have to be updated.
For now I recommend to go back to last released TB version.
