In order to show Taboola adverts, arstechnica.com is breaking the browser "back" button / gesture / etc:

You will need the following steps to reproduce it:
1. Use a "mobile" device OR an emulator including Firefox "Responsive Design View" (ctrl+shift+M). To reproduce, you might need to select a mobile device i.e. NOT leave it as the default device "Responsive design".
2. Open the link (above) in a new tab
3. Delete all cookies for the site (Firefox: tap the lock in the address bar, select "Clear cookies and site data", tap "remove" or "DELETE").
4. Close the tab.
5. Open the link (NOT in a new tab, because that escapes the emulator)
6. Press the usual "accept cookies" button.
7. Use the browser "back" button, or the "back" touch gesture, or whatever.
Expected result: browser returns to the original page (here).
Actual result: see linked imgur.
The screenshot does not admit to using Taboola ads. It just says "sponsoed". But I think some of them are the same as ads shown at the end of the page (when adblock is disabled), and I think those were labelled as Taboola ads.
I've noticed this broken back button on other sites too (immediately after I re-installed Firefox and lost my previous adblock setup. Ugh!).
