I've recently switched back to Firefox from Chrome. I'm currently running version 62.0.2 on MacOS (High Sierra 10.13.4). I mostly imported bookmarks from my old Chrome session, and I didn't have an Firefox Sync account so I created one.
I've been experiencing issues with certain websites such as Facebook, or Paypal. When I try to go on these websites, they won't load very quickly compared to others, and they end up breaking Firefox completely. By that I mean that other tabs seems to act as if there was no internet anymore. An example would be Spotify, who simply stops playing music as soon as I go on these websites, or Gmail that claims there's no connection to the internet. Opening new websites (that usually load without any issue) doesn't work anymore, I get a permanent "Waiting for <website.something.tld> in the lower left corner".
This was after a fresh installation of Firefox. I've also experimented these issues, with exactly the same websites, on my other computer which runs Firefox 64 (I think?), on a Windows 7 box. I've tried pretty much everything in the help section listing fixes for websites that load slowly, etc. including resetting Firefox completely, but the issue doesn't go away.
These websites still load fine in Chrome.
I would like to know if there are other steps I could follow in order to solve that problem.
