This review could be 5 stars if I could locate the button on Mac Firefox/Mozilla. Locating the button is not straight forward however eventually I could do it on the personal PC. Then I spent >1 hr to search on Mac Firefox and on internet to find the button on the MAC , but eventually I gave up. Without a visible button to click the extension/add-on is unusable. Where I could use it (PC) it appeared to be fabulous. Very upsetting

Not open source. I don't trust it.

we need select from search bar, implement it other plugin.

add a shortcut may give better experience

The botton doesn't show up on firefox so I can't use it.
