Comments on: Firefox Quantum Eats RAM Like Chrome

I think Firefox Quantum 68 simply has a severe memory leak. Looking at the process in 'top' (not glances, I didn't think to use it at the time), I can sit there and just watch the RAM get sucked into a useless vortex of unused JavaScript objects. That, and the browser itself recruited no less than 107 sub-threaded processes to run: (drumroll please)..... ONE. SINGLE. TAB!!!!!!!!!! Wow. Oh, and 'glances' shows that it uses 5.84GB of my RAM to do so. Guess what tab it was? It was THIS one, for THIS site, to post THIS. VERY. MESSAGE. I'm off to find a browser with a smaller memory footprint now. This is just plain loony. I hope Mozilla gets its act together again soon---and GNOME, too.

I forget to mention that disabling prefetching is done by
Type in the URL entry field
about:config
Then
network.prefetch-next false

You could try the following.

1. Go to preferences.
2. Under the tab “General”, disable the options “Use recommended performance settings” and “Use hardware acceleration when available”. Set “Content process limit” to 2.
3. Disable prefetching (this is also a nightmare with Chrome)

Am facing the same problems on a daily basis, my laptop now freezes a lot. It even gets worse when i open other applications such as VS Code which also consumes a lot of RAM. This surely needs to be checked by Firefox developers.
