I've got some gecko checkouts set in debug mode that I often have to rebuild, meaning their test profile may be removed/regenerated at times. Bringing up a new firefox profile with the default about:home and privacy warnings can take a while. Thanks to some help from nalexander in #build, I've figured out how to make it so new profiles only come up with a single about:blank tab. This method requires using './mach run' for starting the instance.
If you create a machrc file in ~/.mozbuild like so mach settings > ~/.mozbuild/machrc There will be a [runprefs] block in there that is used whenever 'mach run' is used to start the browser. Adding the following prefs turns off all new profile about:home loads and just starts the browser with about:blank: [runprefs] browser.startup.blankWindow=true browser.newtabpage.enabled=false browser.startup.firstrunSkipsHomepage=true browser.startup.homepage=about:blank datareporting.policy.dataSubmissionPolicyBypassNotification=true _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
