Sorry if off-topic, but seeking an addon

As the subject says, sorry if this isn’t an approriate post for this forum, but I’ve been seeking a new version of an old Firefox Addon that I loved.

The addon, Image Toolbar brought back the functionality of much earlier versions of Windows to show a mini-toolbar at the top left corner of any image when you mouse-overed it, with buttons for multiple functions, including “save as”.

I’ve sorely missed this addon, and wondered if there was an existing working addon for Firefox 86+, or if anyone is working on developing such an addon.

I would greatly appreciate and responses to this

Thanks in advance
