Load denied by X-Frame-Options allow in Firefox

Question

how to allow in firefox viewing content site secure by X-Frame-Options like www.google.com

i add in (about:config) settings

browser.frames.enabled = true

and its worked for some time but now it's not working again

Answer 1

I've created an add-in for Firefox which ignores all x-frame options, see https://addons.mozilla.org/en-US/firefox/addon/ignore-x-frame-options/

Btw, this this question is similar to Disable X-Frame-Option on client side

Answer 2

I find good solution not for firefox but for chrome:

plugin: Ignore X-Frame headers
