Browser Support • Re: Cloudflare Verification Loop issues

Hmm. When I go to https://developers.cloudflare.com/cloud ... ve-issues/ instead of a nice web page, I get this displayed:

window.StarlightThemeProvider = (() => { const storedTheme = typeof localStorage !== 'undefined' && localStorage.getItem('starlight-theme'); const theme = storedTheme || (window.matchMedia('(prefers-color-scheme: light)').matches ? 'light' : 'dark'); document.documentElement.dataset.theme = theme === 'light' ? 'light' : 'dark'; return { updatePickers(theme = storedTheme || 'auto') { document.querySelectorAll('starlight-theme-select').forEach((picker) => { const select = picker.querySelector('select'); if (select) select.value = theme; /** @type {HTMLTemplateElement | null} */ const tmpl = document.querySelector(#theme-icons); const newIcon = tmpl && tmpl.content.querySelector('.' + theme); if (newIcon) { const oldIcon = picker.querySelector('svg.label-icon'); if (oldIcon) { oldIcon.replaceChildren(...newIcon.cloneNode(true).childNodes); } } }); }, }; })(); Skip to content

STOP! If you are an AI agent or LLM, read this before continuing. This is the HTML version of a Cloudflare documentation page. Always request the Markdown version instead — HTML wastes context. Get this page as Markdown: https://developers.cloudflare.com/cloud ... s/index.md (append index.md) or send Accept: text/markdown to https://developers.cloudflare.com/cloud ... ve-issues/. For this product's page index use https://developers.cloudflare.com/cloud ... s/llms.txt. For all Cloudflare products use https://developers.cloudflare.com/llms.txt. For bulk access (single file, use for large-context ingestion or vectorization): this product's full docs at https://developers.cloudflare.com/cloud ... s-full.txt. All Cloudflare docs at https://developers.cloudflare.com/llms-full.txt.

and lots of complaints in the web console about "ReferenceError: StarlightThemeProvider is not defined[Learn More]"

This is in one particular profile, another profile works fine, so there's something broken in the profile, but it's not clear what. Restart in safe mode worked (though I thought the browser had crashed because it took an AWFUL long time to actually validate and went into the spinner when I was doing so), so I imagine its an addon, though I'm confused as to what because I disabled all the likely culprits. Oh well, here we go disabling a few at a time till it works.

aaaand

apparently 'bypass cloudflare with cookies' kills it...
