Sometimes I use Firefox to open a webpage with flash animations or videos, often prompting "Adobe flash player plugin has crashed", animations or videos cannot be played, closing Firefox and opening it is still the same. Why does this happen? Firefox is generally not compatible with flash player. They belong to different companies and are constantly upgrading, which is prone to compatibility problems.

Adobe flash player keeps crashing in Firefox in four ways: disable flash player plugin to prevent crash, disable Firefox protection, disable flash player hardware acceleration, and update the latest version of flash player. Let's start by modifying the Firefox configuration.

3. Finally save it. If it cannot be saved, it is because the currently logged in user does not have permission, you can copy the file to another disk and modify it before overwriting the original file; or use the administrator user to log in to modify. After making the change, open Firefox and use flash play to see the video to test that if it will crash.
