Pale Moon is not loading the (dynamic) favicon for the Syncthing GUI. Confirmed this with a fresh Pale Moon profile and fresh install of Syncthing.
The favicon is dynamic based on scripting, but it appears that Pale Moon does not update the favicon after initially loading the page (the tab and URL bar only ever show the generic moon icon, the favicon never resolves). This is the case both for localhost browsing (http & https) and public (https) IP/URL installations.
The html source for the Syncthing GUI shows this for the favicon entry:
Code: Select all
<link rel="shortcut icon" href="assets/img/favicon-{{syncthingStatus()}}.png"/>
Chrome displays the favicon appropriately on first load and as it updates. FireFox fails to load the favicon initially, but it does update the tab and URL bar icon once the page has loaded.
See the workaround posted at https://forum.syncthing.net/t/fixing-sy ... efox/15726 for details.
