Yesterday I've installed Linux Mint Mate 19 to old laptop with 1Gb RAM. Desktop environment is pretty fast, but after launching firefox it completely hanged. Just one tab with youtube in a few seconds drop the system to deep swaping.
Then I've installed chromium-browser and have played youtube video more than two hours. And swap stayed almost clear.
I think that Linux Mint installer have to install a chromium-browser instead of firefox when the system has a lack of memory.
I'm a firefox fan, but here is no another solution except this one.
