As a result of gepus' posts here:
..and my following issue report @ GitHub:
gorhill suggested a new, separate filter, to address "Legacy"-specific issues:
https://github.com/uBlockOrigin/uAssets ... -472825784
This now seems to have become a reality:
https://raw.githubusercontent.com/uBloc ... legacy.txt
After a minor hickup (which you can read about in the GitHub report above), uAssets' new "Legacy" filter is now included in uBO v188.8.131.52.
If you upgrade from an older version:
--To get the new "uBlock filters -- Legacy" list, you will have to back up your uBO settings (bottom of Settings pane in uBO's dashboard), then restore them.
This will force uBO to discard its internal version of the content of assets.json, which tells uBO where external resources are located.
gorhill has also issued a silent update for v184.108.40.206 now (Old XPI file = 2,250,597 bytes / New XPI file = 2,250,740 bytes).
The updated build includes a fix for the minor issue (which I reported in the GitHub thread above), regarding an outdated filterlist in uBO Legacy, before updating it for the first time.
