I created an WebExtension to force Facebook into the old layout - OldLayout.com

It's very simple, but it doesn't seem to work in Opera. So I tested other extensions that change the user-agent header in requests, and none of them seem to work either! I'm using https://manytools.org/http-html-text/http-request-headers/ to look at the actual request headers being sent, and the user-agent header is never being modified, by any extension.

My code is extremely simple, and uses chrome.webRequest.onBeforeSendHeaders.addListener() to intercept headers and change user-agent. Full source is here: https://github.com/matt-kruse/old-layout/tree/master/extension

I can't find any documentation that says webRequest is broken in Opera. But, I am also not a regular Opera user so I don't know if I'm missing a setting or something that is required for these to run? Any tips at all?

@Elyss Did you read the popup messages? It contains a full explanation, as well as a link to the FAQ. Everything is very well explained.

@pioneerisloud Can you give me any details? What is the url that gets stuck? The latest attempt at a fix is to use upload.facebook.com which is the old layout, but perhaps you are hitting a case where it doesn't work?

I have published version 5.0 for Opera which should fix the problems, at least for now. See the FB Page for more info!

@Ambaradanner If you open a new tab and type in facebook.com does it work? Are you trying to access from Speed Dial? It works well for me in all my tests, as well as for thousands of other Opera users. I'm trying to figure out why a few people seem to have issues.

@Tomi93 Yes, I've learned that launching Facebook from Speed Dial causes the extension not to run. I don't know if this is an Opera bug, but I am actually working on it right now to see if I can fix it!

@Bowaca Which version of Opera on which OS? I am trying to figure out why it works for most people but not for a few. Do you have any other extensions installed?
