The biggest pro for me is the vertical tabs. It’s got the same vertical tabs that Edge has which are great. I only use Edge at work but it’s great especially when you have a web based production environment like nCino that you work in all day and have dozens of tabs open. You can group them up nicely and keep yourself organized. Floorp is based off of Firefox ESR so it’s on an older build (but up to date security). The current build is based off FF 115 while FF is on 129 now.
