Does it kill Firefox if it tries to go over the limit? I think I tried this once and if there is a memory leak it just closes itself (which is batter than hogging the whole system, bit still)
No, it just limits the amount of RAM that Firefox (or whatever other application you launch with these parameters) will see.
A few Firefox tabs may crash occasionally as a side effect. And obviously if Firefox eats up all of the 8GB it’s allocated it may crash itself though usually it doesn’t and tabs will crash before the browser crashes.
