Can I prevent websites from disabling zoom?
I created a bookmark in Mobile Safari with this url

javascript:document.querySelector('meta%5Bname=viewport%5D').setAttribute('content','width=device-width,initial-scale=1.0,maximum-scale=10.0,user-scalable=1');


The easiest way to setup this bookmark is by:


Add a bookmark to any page
Edit the bookmark and set the url to the url I have above


Now anytime you are on page that you can't zoom then click the bookmark icon and select the bookmark you setup.  Then you can pinch and zoom.
