AdGuard VPN Browser Extension version

2.0.16

Environment

- OS: MacOS
- Browser: Chrome

Issue Details

In the extension, we have implemented a mechanism that triggers the onAuthRequired event whenever the proxy settings are changed.

https://github.com/AdguardTeam/AdGuardVPNExtension/blob/f2a4fad5291a5e7269531418aa0049acc2444988/src/background/proxy/chrome/proxyApi.ts#L139-L146

We created this mechanism to prevent situations where the onAuthRequired event doesn't fire for certain requests, such as those involving websockets. This works as expected in Manifest V2 (mv2), with the onAuthRequired event firing every time. However, in the extension built on Manifest V3 (mv3), it doesn't fire.

Expected Behavior

The onAuthRequired event is designed to fire every time a request is sent via a proxy.

Since the old workaround works no more in MV3, we should try a different one now, even uglier than the old one:

try {
    const ret = await chrome.windows.create({
        url: `http://${nanoid()}.${PAC_SCRIPT_CHECK_URL}`,
        focused: false,
        state: 'minimized',
    });
    await new Promise(resolve => setTimeout(resolve, 2000));
    await chrome.windows.remove(ret.id);
} catch (ex) {
    console.log(`Error while using the workaround to force onAuthRequired: ${ex}`);
}

The idea is to open a new hidden window which will "trigger" onAuthRequired and make the browser forget about cached credentials.

We should also carefully assess how annoying this hidden window is on both macOS and Windows.
