Trigger trusted event via debugger - firefox-addon

Question

I'm looking at publishing an app to the firefox addon store which requires "debugger" in order to fire trusted touch events.
However I'm getting an error when adding debugger and can't find much information on it
Reading manifest: Warning processing permissions: Error processing permissions.4: Value "debugger" must either: must either [must either [must either [be one of ["idle"], be one of ["menus.overrideContext"], be one of ["search"], be one of ["activeTab"], be one of ["cookies"], be one of ["scripting"], or be one of ["webRequest", "webRequestBlocking", "webRequestFilterResponse.serviceWorkerScript"]], must either [be one of ["mozillaAddons"], be one of ["normandyAddonStudy"], be one of ["urlbar"], be one of ["activityLog"], be one of ["networkStatus"], or be one of ["telemetry"]], be one of ["alarms", "storage", "unlimitedStorage"], be one of ["captivePortal"], be one of ["identity"], be one of ["menus", "contextMenus"], be one of ["geckoProfiler"], be one of ["contextualIdentities"], be one of ["dns"], or be one of ["theme"]], must either [must either [be one of ["idle"], be one of ["menus.overrideContext"], be one of ["search"], be one of ["activeTab"], be one of ["cookies"], be one of ["scripting"], or be one of ["webRequest", "webRequestBlocking", "webRequestFilterResponse.serviceWorkerScript"]], be one of ["clipboardRead", "clipboardWrite", "geolocation", "notifications"], be one of ["bookmarks"], be one of ["browsingData"], be one of ["devtools"], be one of ["find"], be one of ["history"], be one of ["pkcs11"], be one of ["sessions"], be one of ["tabs", "tabHide"], be one of ["topSites"], be one of ["browserSettings"], be one of ["downloads", "downloads.open"], be one of ["management"], be one of ["privacy"], be one of ["proxy"], be one of ["nativeMessaging"], or be one of ["webNavigation"]], or match the pattern /^experiments(\.\w+)+$/], or must either [be one of ["<all_urls>"], must either [match the pattern /^(https?|wss?|file|ftp|\*):\/\/(\*|\*\.[^*/]+|[^*/]+)\/.*$/, or match the pattern /^file:\/\/\/.*$/], or match the pattern /^resource:\/\/(\*|\*\.[^*/]+|[^*/]+)\/.*$|^about:/]
My Manifest file looks like this
{
"name": "App Name",
"description": "App Desc",
"version": "1.0.0",
"manifest_version": 2,
"default_locale": "en",
"background": {
"scripts": ["background.js"]
},
"content_scripts": [
{
"css": [
"css/style.css"
],
"js": [
"main.js"
],
"matches": [
"https://example.com/*"
],
"run_at": "document_end"
}
],
"permissions": [
"activeTab",
"debugger",
"tabs",
"storage",
"webRequest",
"<all_urls>"
],
"icons" : {
"16" : "img/icon-16.png",
"128" : "img/icon-128.png"
}
}
Does debugger work in firefox? Or is there another way to fire trusted events in firefox?
