Question

I’m trying to create an extension for chrome that auto refreshes the page when the page load is failed for any reason.

my manifest.json:

{ "browser_action" : { "default_icon" : "icon.png"
    },
  "description" : "Making your first Google Chrome extension.",
  "icons" : { "128" : "icon.png" },
  "name" : "Tutorialzine Extension",
  "version" : "1.0", 
  "permissions": [
     "webRequest",
     "tabs",
     "<all_urls>"
   ],
  "content_scripts": [
    {
      "matches": ["<all_urls>","http://*/*","https://*/*","*://*/*"],
      "js": ["myscript.js"],
      "run_at": "document_end"
    }
  ]
}

myscript.js :

chrome.webRequest.onErrorOccurred.addListener(function details){
    chrome.tabs.reload(details.tabId);
}

What am I doing wrong? Thanks in advance!

Content scripts don’t have access to most of chrome.* APIs. It’s clearly stated in the docs:

However, content scripts have some limitations. They cannot:
- Use chrome.* APIs (except for parts of chrome.extension)

You should use a background page or event page instead.

Also chrome.webRequest.onErrorOccurred.addListener(function details) is not a valid JavaScript code. function keyword shouldn’t be there. I believe you copied this code from docs, but in docs this type of pseudo-JavaScript is used only to describe function definition (what types of arguments it expects, what type of values does it return etc.).
