I desire the browser to work as well as it did a decade ago. It worked perfectly all the time.

You have on rose colored glasses. As a web developer, no browser ever worked, works, it will ever work perfectly all the time and it’s not even close nor has it ever been. We have been inching toward that for 20 years but we’ll never get there unfortunately as it would require web standards to freeze and infinite effort to achieve.

Now I’m task closing it once every days because an entire window just goes blank white and never context updates.

Weird. I leave FF open for days and weeks on end. Rarely ever have an issue. I don’t see this one in particular. Which OS are you running?

It eats RAM uncontrollably and seemingly never releases what it should and holds on to what it doesn’t need forever.

I agree FF is not efficient enough with RAM, but on the other hand I normally see it under 5 GB despite leaving dozens of tabs open all the time. I think they opt to keep things in RAM so switching tabs won’t feel sluggish. It’s a trade off. I don’t think much of the RAM usage is unintentional.

This really shouldn’t be that hard.

You obviously are not a programmer.
