I have this same problem. I have tried closing out all apps & resetting mutiple times, I have tried plugging it back into itunes & updating. I have not tried resetting it to factory settings because, I am afraid of losing a bunch of stuff like I do everytime I update the iOS software. I have a 1st gen ipad & used it all day long, everyday & absolutely loved it.

But after updating the software it is so unstable & slow, I am getting ready to throw in the towel on both my ipad & iphone. I personally am starting to wonder if these software updates were designed to cause problems with the older models to force people to buy new ones. Just as I start using an app, it crashes, & it is so slow it almost isnt worth using, except to store my old work.

It is good practice to periodically power your device off an back on again!

I had the same problem - safari crashing a lot on my iPad 1. I disabled iCloud, reset, turned iPad off and back on again, etc.

What finally worked - turn off java script in settings, safari.

I turn it on to hide Facebook postings on the web page. It won't work if you leave java off.

I even had to turn it back on for this reply.

So leave it off and only use it if you have to. On fb, a message come on, but here nothing happened when I hit the reply until I went to settings and turned java on.

It's going off again after I hit the reply button!
