[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 #95326

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

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.
