Stack Overflow lets Facebook track users across their sites
I have a Facebook account, this creates limitations when it comes to blocking (e.g. I cannot use a DNS block/piHole).<p>What I found works for me is to use Multi-Account Containers with Facebook being forced-open in a specific container (that's only for Facebook) and then using Firefox's built in Content Blocking to block trackers in other containers (Content Blocking -> Custom -> In All Windows).<p>This allows you to use Facebook but makes it significantly harder for them to track you across other sites (via shadow accounts or your actual profile).<p>For example this works for Stackoverflow where I see:<p>> The resource at “<a href="https://graph.facebook.com/[xxxx]/picture?type=large”" rel="nofollow">https://graph.facebook.com/[xxxx]/picture?type=large”</a> was blocked because content blocking is enabled.<p>On mobile I simply don't install Facebook's apps and use the mobile web browser and still receive notifications via that.
