@tomkrin Try disabling all the extensions and see if the problem clears when you restart Opera. If so, re-enable them one at a time, restart Opera each time, and see which extension causes the problem to repeat. Then disable just that one extension and re-enable all the others to confirm that the extension is, in fact, the only cause. At that point, you can try to track down why the extension is causing the problem in the first place (assuming that it is the cause).
