Support the webRequest API

mario03

Brief Summary
As an extension developer, the webRequest API can absolutely help me to intercept & modify the needed requests made by the browser, which is something that's often needed for my use case.

I am mainly looking for webRequest.onBeforeSendHeaders specifically, However it'd be great if you can support what the browser engine allows you to (I understand how it can be challenging on iOS)

Thanks in advance 🙂

mario03 This is not currently possible because of Apple restrictions on iOS (WebKit can not be altered). webRequest API is mostly already supported on Orion macOS.

Hi! There seem to be some issues with it tho. I have been trying to use the iCloud “Hide My Email” extension with Orion and I have been experiencing all sorts of issues. I filed a bug report with the developer on GitHub here.

The developer’s response was:

I dogfooded the extension in Orion and encountered the same issue. After some debugging I figured out that Orion does not fully implement the extension API. The Chrome version of the extension (MV3) relies on declarativeNetRequests, whereas the Firefox one (MV2) relies on blocking webrequests. As far as I understand, Orion does not support any of those (possibly by design).
Edit: Came across this extension API support matrix of Orion. It seems that declarativeNetRequests is indeed not supported, but they suggest that webrequests.onBeforeSendHeaders is. Based on that, the Firefox port of the extension should have been working on Orion. When debugging, I confirmed that Orion invokes the onBeforeSendHeaders listeners of the extension but for some reason it did not actually apply the header modifications. Probably worth flagging this with the folks at Orion.

Could you please look into this?

Did you try it?

@Vlad Yes he did (https://github.com/dedoussis/icloud-hide-my-email-browser-extension/issues/45)

I also just tried both Chrome and FF extensions and neither of them work for me (they do not detect that i'm logged in on icloud.com)

Does update with WebKit on ios 18.4 address this issue?
