Does Not Show Pictures Rated 1 out of 5 stars

I used to love this add-on; gorgeous pictures! Now it hangs up, just showing a waiting icon without showing any pictures and I have to shut down firefox to stop it. Support link goes to website for pictures only, no support or contact information.

From google search I found a similar complaint but resolution for me failed: Not really knowing the cause now, but you can avoid this by Right click FoxSaver icon=>Options...=>Choose Photos=>"Browse cache directory", and remove all files there.
