FF 19 compatibility Rated 4 out of 5 stars
Need new update for FF19.This review is for a previous version of the add-on (0.2.8.18).
It's still pending review. The way i see it you have a few choices:
1. Install from https://addons.mozilla.org/en-US/firefox/addon/image-assistant/versions/
2. If urgent, feel free to email firstname.lastname@example.org about this.
P.S. Using an ESR update would be another work-around option.
