Recently made the switch to Mint from Windows. I am having a problem with FF though. Randomly but very frequently I see your most basic page load very slow if not at all. I have disabled hardware acceleration as some research has suggested but it still has the same issue. This happens on both my laptop and desktop.
Weird, I’ve never had an issue like this (using mint as well). You sure it’s just Firefox? It could be an internet issue causing stuff to load slowly.
