I have been doing puzzles on Jigzone for years and after the last Firefox update (last week) my sound messed up. We bought a new sound card thinking that was the problem but it didn't change anything. The sound starts sounding garbled & then quits entirely. This affects ALL my sounds, including system sounds. If I unplug the new external sound card it fixes it but if I go back to Jigzone it does it again. This does not happen when I use Pale Moon so it can't be the puzzle site. I much prefer using Firefox. Please help!
