How I can prevent Safari popups to increase database size on iPad? Recently I have been getting popups on my iPad2 when using Safari. They say:

Increase database size?
Do you want to allow &quot;https://mobile.twitter.com&quot; to use up to 10 MB storage on your iPad?
Cancel Increase

where Cancel and Increase are buttons.
This popup just occurred five times in succession. I have seen it for Twitter (as shown here) but also (I think) for other sites (Gmail?).
Is there any way to prevent this? Or should I use another browser?
There is no easy way to circumvent this behavior in Mobile Safari.

I know of no alternative browser that accomplishes what you ask, but perhaps if someone else does they will answer or edit my answer.

You can avoid those sites, or give more space when asked. It's one of those "we can't adjust the wind, but we can adjust the sails or steer the boat elsewhere" kind of things at present.
