[BUG] [Claude in Chrome] All tools blocked on reddit.com (and redd.it) with "not allowed due to safety restrictions" since 2026-09-18 — worked through 2026-09-17

### Preflight Checklist

- [x] I have searched [existing issues](https://github.com/anthropics/claude-code/issues?q=is%3Aissue%20state%3Aopen%20label%3Abug) and this hasn't been reported yet
- [x] This is a single bug report (please file separate reports for different bugs)
- [x] I am using the latest version of Claude Code

### What's Wrong?

Since the morning of 2026-09-18 (CEST), every Claude in Chrome tool call targeting Reddit fails with `This site is not allowed due to safety restrictions.`

Affects `navigate`, and for a reddit.com tab opened manually also `computer` (screenshot) and tab context. The same read workflow (navigate + read_page/get_page_text on subreddit threads) worked daily through 2026-09-17 in the same Chrome profile, same extension, same account. Nothing changed on my side between the last successful run and the first failure.

Blocked identically:
- https://www.reddit.com/...
- https://old.reddit.com/...
- https://reddit.com/ (no www)
- https://redd.it/ (Reddit's shortener, a separate domain)

Working normally in the same session: github.com, notion.so, reuters.com.

Already tried, no change:
- removed all reddit.com entries from Settings → Permissions → "Your approved sites" (there were three duplicates with no "Last used"), re-visited reddit.com, re-approved
- restarted Chrome

Why this looks like a policy change rather than a config issue: redd.it is a separate domain and is blocked too — a per-site approval problem would not cover it. The Help Center article "Use Claude in Chrome safely" lists only financial, adult and piracy sites; Reddit / "social media" is not mentioned.

Related: #58464, #47244, #92229 (domains blocked despite approval).

### What Should Happen?

Either navigation works (the domain is user-approved and not in any documented blocked category), or the error message names the policy/category that blocks the domain so the user can stop debugging their own settings. If Reddit is now intentionally blocked, the Help Center should say so.

### Error Messages/Logs

```shell
mcp__claude-in-chrome__navigate → This site is not allowed due to safety restrictions.
(same for old.reddit.com, reddit.com, redd.it; screenshot/tab context on a manually opened reddit.com tab fail with the same restriction)
```

### Steps to Reproduce

1. Chrome (Windows 11) with the Claude in Chrome extension, site access "On all sites", reddit.com present in Settings → Permissions → "Your approved sites".
2. From a claude.ai chat with the Chrome connector enabled, ask Claude to navigate to https://www.reddit.com/r/homelab/
3. Observe: `This site is not allowed due to safety restrictions.`
4. Repeat with https://old.reddit.com/r/homelab/ and https://redd.it/ — same error.
5. Ask Claude to navigate to https://www.reuters.com/ or https://github.com/ — works.
6. Open https://www.reddit.com manually in the same profile, open the Claude side panel, ask for a screenshot — Claude reports it sees the tab but cannot read it.

### Claude Model

Not sure / Multiple models

### Is this a regression?

Yes, this worked in a previous version

### Last Working Version

Unknown exact version — extension auto-updates. Last successful run: 2026-09-17 ~17:00 CEST, same profile. First failure: 2026-09-18 morning CEST.

### Claude Code Version

N/A — issue is in the Claude in Chrome extension used from claude.ai (web), not from the CLI. Extension version: [chrome://extensions → Claude]. Claude 1.0.93

### Additional Information

Help Center reference: "Use Claude in Chrome safely" (support.claude.com) — lists financial, adult and piracy categories only, and asks users to report gaps.
Screenshots of the error and of the approved-sites list available on request.

Start by reproducing the failure in the Claude in Chrome extension using the listed Reddit, redd.it, Reuters, and GitHub URLs, then compare the approved-sites settings and the behavior of navigate, computer, and tab context. Review related issues #58464, #47244, and #92229. Done means the policy behavior is corrected or the restriction and its category are clearly surfaced in the error and Help Center.
