What many others have already said - it's slower and many popular sites don't work properly on it. I don't feel like randomly having websites break when I am trying to get things done.
Even on a newer computer Firefox feels jagged and hangs. Memory leaks still happening years later. It is so frustrating to see Firefox using 1.5GB of RAM when only 2 tabs remain.
Quantum helped a lot, but it's still not enough for me and many others.
Really? Do you have examples? I haven’t faced this issue. Some websites breaks somehow if you block 3rd party tracking (by breaking I mean that some pictures or video embedded into the page won’t load), but that’s an opt-in feature so I don’t think that’s what you mean.
