Summary
This PR corrects the compatibility data for
navigator.share()andnavigator.canShare()(specificallydata_text_parameter) in Firefox and Firefox for Android.Changes applied:
Firefox (Desktop):
version_added: "96"which appears to have been inadvertently removed in PR Update Edge data for api.Navigator.share #23687.dom.webshare.enabledflag configuration to accurately reflect that this feature requires a preference setting.Firefox for Android:
"mirror"to explicit version numbers ("79"forshareand"96"forcanShare) to bypass the flag requirement issue.Context and Verification:
firefoxentry requires thedom.webshare.enabledpreference. However,firefox_androidis defined with"accepts_flags": false. Consequently, the build script incorrectly resolves the mirrored support status tofalse.canSharestatus: There appear to have been historical bugs regardingdata_text_parametersupport incanShareon Android. Although I was unable to trace the specific details or issue tracks myself, I have confirmed on a physical device (latest Firefox for Android) that it currently works as expected.Related issues
