firefox doesn't show prompt to allow Local Network Access
Last Friday August 21 2026 my Firefox was updated from version 153.0.4 to version 154.0. Ever since then i can't use any of the Azure functions needed to see dead-letters in our service bus explorer. When i try the same in edge or chrome i get a prompt to allow access to local device network. Firefox doesn't show the prompt. In my settings no websites are listed in the Permissions and data list. When i look at the site specific permissions (shield button -> show site information -> permissions) it is set to default prompt. Clearing cookies or accessing through a private window makes no difference. I need to give Azure access to local network otherwise it throws a web socket error whenever i try to peek at any of our service bus messages. Anyone any ideas?

in about:config switching "network.lna.websocket.enabled" back from true to false does indeed fix the problem. When set to false i no longer get the websocket error when calling the peek/receive servicebus azure functions.

Setting permission to allow on the site directly doesn't work, because it's the domain that the underlying service bus peek function uses that needs the permission.
Would you be willing to file a bug with these details, potentially based on the change in bugzilla.mozilla.org/2042339 …?
Generally this is the preference changed: hg.mozilla.org/integration/autoland/rev/a6d2a53cca50
You can either flip network.lna.websocket.enabled back, or potentially add exclusions to network.lna.skip-domains …?
