Can't run scripts on gmail in chrome

I have created a chrome plugin but it is running on all google sites except gmail, how do I make it run on gmail?
My manifest file:
{
"manifest_version": 2,
"name": "drc",
"version": "0.1",
"background": {
"scripts": ["bg.js"]
},
"content_scripts": [
{
"matches": [
"<all_urls>"
],
"js": ["content.js", "onclic.js", "Jquery.js"],
"css": ["drpdwn.css"]
}
],
"browser_action": {
"default_title": "Append Test Text"
},
"permissions": [
"tabs",
"activeTab",
"https://mail.google.com/*",
"http://mail.google.com/* "
]
}
Error I get is, cannot read property 'parentNode' of null

Trying to make an extension

I have an extension that i'm trying to add content scrips alongside background scripts but it just says invalid when trying to temp load.
{
"description": "Creates tasks and calculates application incomplete date",
"manifest_version": 2,
"name": "Task Creator",
"version": "1.31",
"permissions": [
"http://*/*", "tabs", "https://*/*",
],
"icons": {
"48": "icons/page-48.png"
},
"web_accessible_resources": [
"style/popUpStyle.css",
"script/popUpTask.js",
"script/logicTaskFiller.js",
"js/autosize.js",
"style/jquery-ui.css",
"js/jquery-1.12.4.js",
"js/jquery-ui.js"
],
"content_scripts":{
"matches": ["*urlhere.com*"],
"js": ["comSendForm.js"]
},
"background": {
"scripts": ["background.js"]
},
"browser_action": {
"default_icon": "icons/page-32.png"
}
}
I'm not quite sure where i'm messing up. It works instantly after I take out the content scripts, but I'm doing multiple things with this extension and I really do need the content scripts to run on a certain page. Any help is appreciated.
error message
1477430058898 addons.webextension. ERROR Loading extension 'null': Reading manifest: Error processing content_scripts: Expected array instead of {"matches":["*://url.com/"],"js":["comSendForm.js"]}

The error that you are getting is that your manifest.json has the value of the content_scripts key as an Object. The value of the content_scripts key needs to be an Array of Objects, not just an Object.
In addition, you have the following problems:
The line:
"http://*/*", "tabs", "https://*/*",
should not have the trailing ,. This is actually reported as the first error, so you may have copied the contents of your manifest.json file inaccurately.
Your matches pattern is invalid. You probably wanted something like:
"matches": ["*://*.urlhere.com/"],
With all of those changes your manifest.json would look like:
{
"description": "Creates tasks and calculates application incomplete date",
"manifest_version": 2,
"name": "Task Creator",
"version": "1.31",
"permissions": [
"http://*/*", "tabs", "https://*/*"
],
"icons": {
"48": "icons/page-48.png"
},
"web_accessible_resources": [
"style/popUpStyle.css",
"script/popUpTask.js",
"script/logicTaskFiller.js",
"js/autosize.js",
"style/jquery-ui.css",

}

Chrome extension content script

I want to use a plugin on the content page, this is my code :
manifest
{
"manifest_version": 2,
"name": "Test",
"description": "foo",
"version": "1.0",
"browser_action": {
"default_icon": "icon.png",
"default_popup": "popup.html"
},
"options_ui": {
"page": "options.html",
"chrome_style": true
},
"permissions": [
"activeTab",
"storage",
"https://google.com/*"
],
"content_scripts": [{
"matches": ["http://google.com/*"],
"js": ["jquery-3.1.0.min.js", "simply-toast.min.js"],
"css": ["simply-toast.min.css"],
"run_at": "document_end"
}]
}
content.js
...
$.simplyToast('success', 'This is a success message!'); // Line 72
jQuery works fine but I get this error when trying simpleToast content.js:72 Uncaught TypeError: $.simplyToast is not a function .Not sure what I'm missing here.

Wrong Syntax I guess!
$.simplyToast('This is a success message', 'success'); // Line 72

How do you deal with Duplicate File names in Manifest.JSON for a chrome extension?

I am trying to implement a Github library within an extension. The file system has multiple files with the same names like "index.js" but when I look to reference these within the Manifest.json I feel like They will just throw errors
{
"manifest_version": 2,
"name": "log",
"description": "log",
"version": "1.0",
"browser_action": {
"default_icon": "favicon.png",
"default_popup": "popup.html"
},
"options_page": "options.html",
"background": {
"scripts": [ "eventPage.js", "background.js", "Gruntfile.js", "unittests.js", "crypto.js","index.js", "aes.js", "blowfish.js", "cast5.js","des.js","index.js","towfish.js", "index.js","md5.js","ripemd.js","sha.js", "armor.js", "basic.js", "index.js", "key.js", "keyring.js", "packet.js", "Signature.js", ]
},
"content_scripts": [
{
"matches": [ "<all_urls>" ],
"js": [ "Log.js" ]
}
],
"permissions" : [
"storage",
"notifications",
"contextMenus",
"http://*/*",
"https://*/*",
"tabs"
]
}
Can someone help me find documentation on how to handle file systems duplication within the Manifest.json?
