Latest update, javascript crashes chrome and firefox

Hello,

Thanks for the great product

Im trying to apply a restore. I succesfully restored from the previous update, updated the plugin, and then attempted to apply a different restore. In both chrome and firefox (latest versions ubuntu mint) clicking the restore button brings up the popup with the list of content to restore. I select all the checkboxes, click “restore”. The upswipe animation to begin the restore process never finishes and the page eventually freezes completely. Chrome asks to kill or wait after a couple of minutes.

What is happening?
