why "TypeError: d.createdElement is not a function"
since I have created App Tabs every time I open Firefox this window appears "TypeError: d.createdElement is not a function" and after clicking OK a new window says "Prevent this page from creating additional dialogues" with a tick box that doesn't make much sense to me. what can I do not to see those windows.

This issue can be caused by an extension that isn't working properly.
Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
- Don't make any changes on the Safe mode start window.

I decided to cancel a couple of last App Tabs and the windows disappeared. So, I presume it has to do with those websites. I have five App Tabs active insteas of seven. Waiting until I load a few more (different ones) and see how it goes. Thanks a lot anyway. Cheers. Claudio
