Description (last modified by mario)

This is a follow-up ticket to #4010 where we fixed a memory leak which caused crashes due to memory pressure. Since closing #4010 the memory usage while browsing websites has greatly improved. However there's still a noticeable difference compared to other apps using UIWebView:

There is no hard and fast amount of content that needs to be loaded, or in a particular way before it crashes. But, it does happen sometimes.
Jetsam is attached.
This was also tested against Opera iOS with no reproduction.


ABB 1.3.2 (926)
iPhone 6 Plus
iOS 9.3.1

How to reproduce

  1. Visit content heavy sites such as or
  2. Browse through multiple images and or articles

Observed behaviour

After loading a series of images or articles, the browser crashes.

Expected behaviour

The browser should not crash.
