Adapted from ​https://platform.passbrains.com/dashboard/view-ticket.php?ticket_no=ASA-61

Environment

Mac + OS X 10.7 + Safari + English
ABP version 1.8.12.1423

How to reproduce

1. Install ABP Safari extension
2. When "Adblock Plus has been installed" page opens, do not click any other buttons apart from the 'Contributor Credits' link.
3. When Contributor Credits page opens click back browser button
4. When "Adblock Plus has been installed" page opens click Facebook, Twitter or Google + button in Tell your friends section

Observed behaviour

All JS links on "Adblock Plus has been installed" page stop functioning if click Contributor Credits link and then click Back browser button.
Following functionality stop function with this scenario:

• disable link
• Facebook, Twitter, Google + buttons in Tell your friends section
• All toggles in Adblock Plus can do more than block ads section

Expected behaviour

All JS functionality should continue function after navigate to Contributor Credits page and then back to "Adblock Plus has been installed" page.

Background

It seems that the page is not being reloaded properly (e.g. "DOMContentLoaded" event does not get fired) when navigating back to it via the back button. There are a couple of reports of people encountering the same issue (e.g. ​jQuery) blaming it on the ​BFCache.

Since the suggested "pageshow" event is equivalent to the "load" event, it's getting fired later than the "DOMContentLoaded" event so we should use both to ensure that the page is being initialized as early as possible.

What to change

Add a listener for the "pageshow" event to initialize the page in case "DOMContentLoaded" was not fired.

I reproduced this, but I found that it only occurs if the user does not select one of the buttons as mentioned above before selecting the Contributor Credits page.

Reproduced on OS X 10.10.3 Safari 8.0.6 ABP 1.10.

Closing this ticket because we're going to remove this link with the next iteration of the first-run page and Apple is ending support for Safari extensions in favor of content blocking apps.
