Same here, can confirm

I had similar issue for v0.20.7 and got it resolved by updating to v0.20.11. Also running on MacOS and Node 22.

Upgrading to WXT 0.20.11 solves this issue. Tested on macOS Sequoia + Chrome v142

bun install wxt@latest --ignore-scripts
bun wxt prepare

@zhayes If it's really fixed, let's close this issue :)

bun install wxt@latest --ignore-scripts
bun wxt prepare

Upgrading to WXT 0.20.11 fixes the auto-load, but Chrome becomes unusable when the extension triggers any Google login flow.

When trying to sign in (OAuth or Firebase auth via Google), Chrome shows this screen:

“Couldn’t sign you in — This browser or app may not be secure. Try using a different browser.”

So the browser session started by wxt dev isn’t considered a secure environment for Google OAuth, which breaks extension debuging that depend on it. Anyone know a fix for this maybe? Tried searching, but nothing worked.

@sklaboi That's known issue #1890

Tried bumping to 0.20.11, but it doesn't seem to solve the problem. The behaviors I'm observing

• [Occasionally] Manifest does not load unpack automatically -- I'm not sure how to reproduce this behavior
• [Consistently] Content script is not injected until I refresh browser for the first time
