Firefox 73 starts but only displays blank pages - "Firefox Monitor: malformed breach enty"
Firefox just updated to version 73. However, as it started, it only displays a blank page on any page, - No webpage loads, or attempts to load. I just get blank page. - This includes built in pages such as addons and settings. Reinstalling does not help. Removing the profile does not help. Downgrading to version 71 does work, and now I can use internet again.
I can open the developer console and see the following error: Firefox Monitor: malformed breach enty (... some json)

Hi senchang94, sorry to hear you are experiencing this problem. The most common reason appears to be having Firefox set to run in backwards compatibility mode. The fact that your Firefox's "user agent" string contains "Windows NT 6.2" (referring to Windows 8 rather than Windows 10) does suggest that it could be the culprit.
However, the developers are working on patches for a number of possibly related issues so I can't be sure this is the reason that your Firefox 73.0 wouldn't load content.
For future reference:
Compatibility Mode Problem in Firefox 73
Could you double-check that your regular installation of Firefox is not set to run in backwards compatibility mode? Here's how:
Find the icon you use to start Firefox, and either:
- Right-click a desktop shortcut, then click Properties
- Right-click a Firefox icon pinned to the Taskbar then right-click Mozilla Firefox, then click Properties
You should clear all the boxes on the Compatibility tab for best results (giant screenshot below).
Any difference the next time you start Firefox?
