Great "NO BS" screenshot extension.
Very intuitive yet flexible interface. Not loaded with ads or bloat.
Default naming scheme is excellent for captures.
Been using FireShot for a little over a year now (2020) and it is one of my core extensions I add to my browser upon spinning up a new machine. Can't live without it.
For a free extension there is no comparison, IMO.
I don't write reviews normally but this one deserves one. Just hope it stays this way.
