Start Fennec 2. Visit two successive sites. 3. Tap "Back" 4. Tap "Forward" For this scenario everything works as expected. Scenario 2: 1. Start Fennec 2. Visit 3 successive sites. 3. Tap "Back" twice Expected results: Content for first accessed page is displayed. Actual results: When tapping "Back" for the second time, browser hangs; it looks as if is trying to load something, but that something is never displayed.

Scenario 2 described above works (or this time I've tried it did), but the process is real slow (pages load heavily) For the blow I get the actual results described above: 1. Access google.com; cnn.com and digg.com. 2. Tap "Back" twice in the browser. 3. Tap "Forward" twice in the browser. Actual results: When tapping "Forward" for the second time, browser hangs; it looks as if is trying to load something, but that something is never displayed.
