Be careful with old versions!
These versions are displayed for reference and testing purposes. You should always use the latest version of an add-on.
1. Migrate all Google HTTP references to HTTPS instead.
2. Update JQuery from 1.8.3 to 3.1.1 because jQuery versions older than 2.0 are not supported in Firefox addons anymore (https://github.com/mozilla/addons-linter/blob/master/docs/third-party-libraries.md).
3. Update Firefox compatible max version from 19.* to * (all future versions).
2. Fixed a minor UI issue where the camera icon sometimes still appears on the corner of an image even after the mouse cursor has already moved off of the image.
