LastPass Chrome Extension 4.152.3 Breaking Cloudflare‑Protected Sites (CSS/JS Not Loading)

jonsp01

Since updating to LastPass Chrome extension version 4.152.3, certain Cloudflare‑protected websites (example: 1337x.to) load only as unstyled HTML. CSS and JavaScript fail to load until the LastPass extension is disabled.

I'm on Chrome version 148.0.7778.97 (Official Build) (64-bit).

The website 1337x loads to its normal UI via Incognito mode.

Please escalate to engineering. It appears the content script is interfering with Cloudflare’s JS challenge or blocking external CSS/JS resources
