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?
