Not a big issue, but in v7.0.1, the icon for this extension is missing within the Firefox Add-ons Manager. Within Firefox, press Ctrl+Shift+A, or go to about:addons. The extension's icon should appear next to each extension. The icon is present for all extensions, except Nimbus Screen Capture - editable screenshots.
BTW, the name "Nimbus Screen Capture - editable screenshots" is very long, perhaps you can shorten it to simply "Nimbus Screen Capture"? Thanks.
