Hm. So you're getting the raw URL but you don't have NoScript / block JS specifically? Can you check in an incognito window and if it still happens, ablate all your extensions in a fresh profile (https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles https://support.mozilla.org/en-US/kb/profile-manager-create-...), which is something you might want to keep handy if you really have 100 extensions running and no idea what they all do...
