Today, in addition to new versions of Page Saver, we also released an update to Do Not Disturb (an extension for Mozilla Firefox that suppresses prompts and other behaviors that interfere with unattended use of the browser).

The new version suppresses prompts that may prevent a browser window from closing when a web page uses an onBeforeUnload event handler. This problem was reported by one of our long-time customers, and this enhancement will benefit everyone.

You can update to Do Not Disturb 1.2 from the Firefox add-ons window.
