Web Pages disappear
I am on a Macbook air running Firefox 109.0.1 with DuckDuckGo as the engine. This past week I've had webpages that I am using disappear leaving me with a blank tab. In the middle of the game or puzzle it just disappears and there I am with the Firefox logo on the page. The tab doesn't close, just the content is gone. The back button doesn't work - it's as if I have set a new tab. The two sites that seem to be disappear most frequently are: thejigsawpuzzle.com https://freeonlinemahjonggames.net/dogmahjong2.html both of which we have used for years without problems. It doesn't happen every time we use the webpages but at least once a day. We have restarted the computer and Firefox. This laptop is just a couple of weeks old, could that somehow be the issue?

If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block content (Adblock Plus, NoScript, DuckDuckGo PE, Disconnect, Ghostery, Privacy Badger, uBlock Origin) always make sure such extensions do not block content.
- make sure your extensions and filters are updated to the latest version

Firefox shows a purple shield instead of a gray shield at the left end of the location/address bar in case Enhanced Tracking Protection is blocking content.
- click the shield icon for more detail and possibly disable the protection
You can check the Web Console for relevant-looking messages about blocked content.

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or if userChrome.css/userContent.css is causing the problem.
- switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
- do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window
