I've installed this extension: https://addons.mozilla.org/en-US/firefox/addon/public-ip-display/ I've pinned it and it shows up in the Toolbar, no issues till here. However, when I exit Firefox and open it again, the extension is no longer pinned. I cannot even locate the extension in the list of extension when i click on the little "puzzle" icon that shows you your lists of addons and allows you to pin them. Everytime after I start a fresh session of Firefox, I have to go about:addons find the add on, toggle it off and then toggle it on again (it stays on after restart btw) for it show up in the toolbar. Can you assist in figuring out why this addon is behaving this way? Thanks!
