On Android at least, Firefox PWA's don't seem to support registering system-level things (like 'Share To' handlers) - you need to use a Chrome PWA for that....
I think this "improvement" is pretty poor - If I'm interpreting your post correctly, I think you can set:
browser.download.improvements_to_download_panel false
in about:config
For me:
browser.ctrlTab.recentlyUsedOrder: False
browser.tabs.insertAfterCurrent: True
dom.popup_maximum: 100
browser.download.improvements_to_download_panel: False
I'm seeing this issue as well - clearing cache may work for a moment but refresh the page and logged out as well - it's been broken ever since the issues a few days ago.
