Sometimes browsing of this sites may work but more often the browser crashes always without producing a report.
Also in safari often an error is signaled and the page will be reloaded.
I use ipad 3 with ios 9.3.5
What current ABB iOS version are you using?
What filter lists you have active?
Do you have Acceptable Ads enabled? And does the website loads as a desktop version (www.test.com) or a mobile version (m.test.com)?
Also, where possible, it would be great to know and have a URL where this happens consistently?
Hope to be able to help.
