David Parks 1e71ef1cb8 Bug 1675349: Replace plugin behavior with a basic fallback r=jmathies,mixedpuppy ... The browser currently only enables plugin behavior for Flash and our internal test plugins. This patch replaces support for those plugins with a simple fallback that shows a transparent region where the plugin would have been. It removes the file system search(es) for the plugin dynamic libraries and short-circuits the logic to determine if plugins should do something special -- all implementations now behave the same in the presence of plugin elements. The new behavior is: 1. If the <object> or <embed> element lists a type of something other than "x-shockwave-flash" or "x-test" then the behavior is unchanged. This means that non-plugin types behave properly and unknown types (for example, typos) are also unaffected (they reduce to 0x0 elements). 2. If the <object> element has an HTML fallback in the DOM (see spec for <object> elements) then the fallback is always shown. 3. Otherwise, the element is shown as a transparent region with the size specified in attributes. Differential Revision: https://phabricator.services.mozilla.com/D95902		2020-11-18 15:55:34 +00:00
