This add-on is super helpful when google books preview page cannot be displayed! Work like a charm!

Firefox suddenly started throwing errors on an anime website i stream from. This addon fixed it and allows the videos to play.

Fixes a problem that makes browsing a pain like Reddit Chat. Only thing better would be a way to enter specific sites you want it to work on for better security. Thanks for this extension.

Essential to use recaptcha in pyLoad

I discovered this plugin as a helper for the Infy Scroll extension. Infy Scroll is useful but a little tricky to configure if you want to force Infinite Scrolling on certain sites; a simpler alternative though slightly less powerful is the UserScript Pagetual.

Works for me and nothing bad in the source code, basically removes "content-security-policy" and "x-frame-options" from headers. Thanks!

Works for me.

This extension allow to bypass xframe filter. Works for me

This extension's functionality definitely IS A MUST for browser core!!!
how that could happen they still haven't implemented it..?

Well, it's a solid extension that does what it says on the tin - unfortunately it's no longer enough, apparently. For example I tried to use it to enable previews of Twitter pages in pinboard.in's organize mode - and sure, the view itself loads, but it's broken, because other requests and scripts fail in ways I'm not motivated enough to investigate.

The web has changed. The header itself is incredibly useful - click jacking was a scourge, and sometimes really is. But the approach has its downsides.

Fonctionne parfaitement et extension OpenSource ! Merci

Simply doesn't work. I tried to use it in a HTML file with Google.com, and it still output the same frame is "denied by X-Frame-Options directive set to SAMEORIGIN“.
