As a power user looking to get the features of Vivaldi while remaining on the comforts of Firefox, this extension has been really helpful to me! Kudos to the developer for understanding the needs of keyboard-based users like me. Would highly recommend this to anyone who wants to control their browser from the keyboard. It's certainly useful for non-technical users but I feel that avid terminal users would find the most use out of this. The only small problem is that using "gen" to generate the password results in a window that gets cut off, but it is still copied to the clipboard. I understand that this works on Chromium, but please fix this on Firefox! Otherwise, this is extension is practically flawless.
