Hello, I think it's something to do with AVAHI resolution within the Firefox snap package.
I disabled the AVAHI services on my servers/PCs as it conflicts with .local running on a local DNS server. For some reason .local requests within the Firefox snap package stopped working and just generate the odd SOA .local DNS request. I've now migrated my internal network to .lan and DNS resolution is working correctly. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1956365 Title: Firefox snap package can not resolve .local dns names Status in firefox package in Ubuntu: Invalid Bug description: Firefox snap package does not resolve .local dns names after recent update. After a recent snap package update of Firefox I can no longer resolve .local DNS names for my local network. This ONLY impacts the Firefox snap package. Brave, Chrome and DNS resolution on the local terminal (ping) are working correctly.
