After further testing, the issue keeps occurring under the following scenarios:

• when having 15 tabs open or more, each with a different website (build 0.12.0 (DEV-352)
• when having only one empty tab open but subscribing to the different filter lists in Settings » Adblock Plus » Ad blocking (this one being so far the most reliable way to reproduce it)

First scenario:

1. Make sure to have around 15 tabs open or more with a website each. (In order to do this, tap on the icon at the bottom right corner of the screen and then on the cross also at the bottom right corner. Tap on “Search or enter website name” at the top of the screen in order to enter a URL. Repeat this process with a different website for each tab for 14 more times.)
2. Access the settings by tapping on the Adblock Browser icon in the middle at the bottom of the screen and then on "Settings"
3. Tap on Adblock Plus » More Blocking Options
4. Enable two different options
5. At the top left of the screen tap on Adblock Plus » Back and then “Done” at the top right of the screen
6. Access the settings again by following step 2 and tap on Adblock Plus » More Blocking Options

The different options should be reverted back to the disabled state. However, going only one step back (in this case “Adblock Plus”) and then accessing “More Blocking Options” again, shows the options displayed as they were left before, two enabled and two disabled.

Second scenario:

1. Install Adblock Browser and open it
2. Access the settings by tapping on the Adblock Browser icon in the middle at the bottom of the screen and then on “Settings”
3. Tap on Adblock Plus » More Blocking Options
4. Enable the four different options displayed on the screen by tapping on the toggle switch on the right side next to each option
5. Go back to “Adblock Plus” by tapping on “Adblock Plus” at the top left of the screen
6. Tap now on “Ad blocking”
7. Subscribe to each single filter list by tapping on the toggle switch on the right of each filter list
8. Tap on “Adblock Plus” at the top left of the screen
9. Tap on “More Blocking Options”

The different options in “More Blocking Options” enabled before subscribing to the filter lists should be displayed now as disabled.

Note: this was reproduced in builds 0.12.0 stage-349 (core 1.2.17) and 0.12.0 (DEV-353).

Priority set to P3 as this only seems to occur on iPhone 4S (and below?) and is rather difficult to reproduce.

We weren't able to reproduce this issue reliably. However it "should" be solved due to refactoring of corresponding components.
Please keep this in mind during the next QA iteration and re-open this issue if necessary.

The refactoring happened for 1.2.0 which is why I'll assign them to that milestone even though it has been closed already.
