Starting with Firefox version 62 for Mac, Adobe Flash applets will be run in a more secure mode using process sandboxing.
Adobe Flash will be going away soon, but for now, you can easily install and enable Adobe Flash Player on a Mac computer using a Safari browser. May 08, 2020 Adobe Flash is turned off by default in the new Microsoft Edge. This is because Adobe announced that Flash will no longer be supported after 2020. Microsoft plans to remove Flash from Windows entirely by the end of 2020. Other browsers like Google Chrome, Mozilla, and Safari are also planning on removing Adobe Flash in the same timeframe.
The sandbox is known to prevent the following features from working:
- Print to PDF from the Flash print dialog
- Print to Open in Preview from the Flash print dialog
- Quicklook in the File -> Open menu
- Saving files from a Flash applet
- Flash applets downloading and running the Adobe Air installer
- Flash triggering Adobe Air applications to run
