Hi,

Thank you for your feedback ! I will look into the issue you described, but can you open a issue on GitHub ? It is more convenient to solve the issue because on Firefox on can only reply once and edit are not notified. If you do not have and want to create a GitHub account, you can send me an email with the link on the addon page.

Edit: The like all function is working on my computer, can you please fill an issue on GitHub. With it we can investigate this more easily.
