This add-on was very helpful for me since I have floaters in my eyes and could see them very clearly with a white new tab, but a recent Firefox update made it so that this add-on delays keyboard input by 0.5 seconds, so that when I'm halfway done writing my search query, the new tab refreshes and I lose everything that I typed. It also seems that this functionality is in Firefox by default, so I went ahead and removed the addon. Thank you for developing this when I needed it!
