Firefox was my goto browser once upon a time but in the past few years it's quality has really fallen behind chrome and even edge. The problem starts when I load it up. Unlike chrome or edge that will start instantly(on an SSD), firefox will take at least 5 seconds to boot and become responsive. It is still slow in everything else too such as opening a new tab. Then there are all the little things like having to restart after installing most add ons, or the CTRL+F feature just not being as user friendly as chrome. I just mourn for it now.
