How to disable content_script.js in firefox..?

Question

I haven't installed any plugin so far in my firefox and neither used any extra js script till yet but i don't from where this content_script.js has been enabled and printing unnecessary messages in console like this :

 content script runtime.onMessage: update_shortcuts
content_script.js (line 91)
<System>

2 content script runtime.onMessage: tabupdate
content_script.js (line 91)
<System>

When i tried to look at the path of this script, it shows its a part of firefox any plugin :

resource://gre/modules/ExtensionContent.jsm -> moz-extension://22d1d103-e4d1-431c-bc5e-e2fe1cd8d902/javascripts/content_script.js

Can anyone please tell me what the hell is this script doing and HOW CAN I DISABLE THIS..??

I am using these extensions in FireFox :

Any help will be appreciated..!!

Answer 1

Most likely it's an issue of any firefox addons that you are using. Try using firefox without loading any addons and see if this issue persists.

DO this to load without addons

Launch Mozilla Firefox, click the "Firefox" button, click the small arrowhead next to "Help" and click "Restart with Add-Ons Disabled" in the submenu. Click the "Restart" button to confirm the action and restart Mozilla Firefox. Click the "Start in Safe Mode" button to start Mozilla Firefox without the add-ons.

Here are the steps:

Step 1 Open Firefox In the address bar, type about:config then press Enter on your keyboard Please note, if your version of Firefox was pre-installed on your machine or device, altering settings in this was may void your warranty

Step 2 Click on the I’ll be careful, I promise! button to continue

Step 3 In the search bar, type javascript.enabled to find the preference option of the same name

Step 4 Right-click on the javascript.enabled option, then click on the Toggle menu item The Value column should now read as false, meaning JavaScript is disabled. A Value of true means JavaScript is enabled

Step 5 Restart Firefox then visit whatismyipaddress.ricmedia.com to confirm JavaScript status

The console messages are being caused by the Awesome Screenshot addon. Disable it and they'll stop.

If you're on Windows I recommend ShareX as a very good open-source alternative to Awesome Screenshot.
