I would like to hire a developer to make some tweaks here and there and was wondering if it is possible and how I would go about doing so.
Thank you for replying.
You said its possible to download.
Where on the addon page is the download for the code or to edit code?
Easiest way is to install the addon then open you Firefox profile and get the source from there.
You can not edit the code on Mozilla site.
Right click on the download button, Save link as … then it will download
