Hi,

Would you disable your extension 'Save Button for Pinterest' and see if that will make a difference  ?

If it does, you could contact Baris Derin, the developer of the extension by sending him an email (see under 'More information') :

I tried this and it didn't work.

It's always worked but I used your link to fix problems with Firefox not running faster, etc, without locking up. Ever since then, no Pinterest pins will work even when logged into the Pinterest site. Whatever happened it had killed my access to Pinterest on my laptop and on my Android device.

Could you let us know what link it was that you used, please  ?

Would you give this a try please :
