Setting up Firefox after new install

I just updated my operating system from Ubuntu 20.10 to 21.04. This was an upgrade, rather than a new install, but one of the things it did was replace my Firefox with the latest version.

I’d been having trouble a while ago with Firefox eating up all my memory and processing power and had made a number of changes that, while solving the problem, I forgot to write down. Installing the new Firefox deleted these leaving me with issues again.

Pages won’t load

First problem I have is that a lot of pages won’t load or won’t finish loading. I fixed this by

disabling IPv6: about:config > “Accept the risk and continue > network.dns.disableIPv6 > true

disabling proxy: about:preferences#general > Network Settings > Settings > No Proxy

disabling DNS prefetching: about:config > “Accept the risk and continue > network.dns.disablePrefetch > true

Pages won’t remember me

For commonly used pages, I manually allow them to store session cookies: about:preferences#privacy > Cookies and Site Data > Manage Exceptions > [Enter relevant domains] > “Allow” > Save changes
