If PriceBlink isn't appearing as-expected, please follow the attached troubleshooting steps:
First, please visit this page and confirm that PriceBlink still is not appearing. If you see the yellow bar at the top of your page, then PriceBlink is working properly.
If the bar doesn't appear, do you see the PriceBlink flashlight (shown below) in the grey space to the left of your address bar?
If not, check to see if PriceBlink is still active by clicking on the Safari Menu, Choosing Preferences, and Clicking on the Extensions Tab.
The "Enable PriceBlink" tab should be checked AND your correct country should be selected.
Verify that you are not in Private mode (if your address bar is dark grey, you are in Private Browsing Mode). PriceBlink does not work in Private Browsing mode.
Assuming PriceBlink is still active, but not working, please try the following:
Please disable the add-on and then re-enable it. Then, try this page and seeing if the toolbar appears.
If that doesn't work, let's try uninstalling the add-on and then re-installing it from this page.
Finally, if that doesn't work, it's possible that one of your other extensions is causing the issue. Please disable your other extensions and re-enable them one-by-one to identify the conflicting add-on.
