Firefox very slow after changing networks

Hi, since some weeks, my Firefox browser is super slow after changing networks. For example, when I'm on Wifi and then switching to normal wired network, Firefox is loading any content only very slowly, despite the connection is super fast. Other browsers like Chrome or Edge don't have this problem. The issue can be very easily resolved though: I just have to close and restart Firefox, and it's super fast immediately again. Still it is annoying, as I switch networks pretty often. Please support. Thank you!
