[FEATURE] Detect Claude Chrome extension in other Chromium-based browsers

Adding my +1 to this issue. I'm an Arc browser user on macOS with the Claude Chrome extension installed in Google Chrome.

When clicking "Reconnect" in Claude Code to connect to the Chrome extension, it opens Arc (my system default) instead of Chrome where the extension is actually installed. This completely breaks the workflow.

The proposed solutions all sound great. My preference order would be:

1. Config option in settings.json - set once, works everywhere
2. Environment variable (CLAUDE_BROWSER or CLAUDE_CHROME_PATH) - useful for different setups
3. CLI flag - good for one-off usage

Current workaround of changing system default browser is disruptive since Arc is my primary browser for everything else.

+1 to this issue. I use chromium on Omarchy and Claude Code can't recognize the Claude in chrome plugin.

+1 distrupts all my workflows - I use ZEN

+1 I use brave.

I'm on the M4 Macbook, when I run VM, I make a dev VM with Ubuntu ARM64 edition.

Unfortunately on Linux ARM64, there are no Google Chrome deb builds, so I have to use Chromium there.
Please add support for Claude extension in chromium so that Ubuntu VMs with the ARM architecture can be used.

Brave user here. Extension installs and works fine in the browser, but CLI can't detect it. Having working software that's artificially locked to a specific binary is frustrating.

Settings.json config would be ideal—set once, works across machines.

+1 from an Arc user!

+1 from an Arc user too!!

Please fix 🙏🏼

Have a PR up for this and will try to land it this week sometime.

Barring any blockers this will go in 2.1.8.

lmao 2.1.8 is MIA

Hey @amorriscode , thanks for working on this! I noticed this issue was closed on Jan 14 with the note that it would ship in 2.1.8.

I'm currently on v2.1.12 but still experiencing the original issue - when I click "Reconnect" for the Chrome extension, it opens my default browser (Arc) instead of Chrome where the extension is installed. I don't see any new settings for browser path selection in the docs or config.

Could you clarify what was included in the fix? Was it auto-detection for certain Chromium browsers, or something else? Thanks!

@amorriscode this issue is marked as closed but where can we get the documentation to actually make this work?

I'm on Claude Code 2.1.12, in Arm64 Ubuntu 25.10 VM, running on Mac OSX host.
The only browser installed is Chromium, with Claude extension fully working within the browser.

When I run claude --browser , i just get

The browser extension is still not connected. Here are some things to check:                                                                                                                                         
                                                                                                                                                                                                                       
  1. Is Chrome running? Make sure you have Chrome open                                                                                                                                                                 
  2. Is the extension installed? Check if the Claude extension appears in your Chrome extensions (chrome://extensions/)                                                                                                
  3. Is the extension enabled? Make sure it's toggled on                                                                                                                                                               
  4. Did you restart Chrome? If you just installed it, Chrome needs a restart                                                                                                                                          
                                                                                                                                                                                                                       
  You can also check if the extension icon appears in your Chrome toolbar. 

What are we supposed to pass along / configure for Claude Code to connect to the Chromium Claude extension?

Hi folks,

Until @amorriscode can get to this we have the following workaround (scroll down for instructions on MacOS and Linux): https://github.com/anthropics/claude-code/issues/14391

I created a workaround for this issue that automatically configures Native Messaging Host for Chromium-based browsers:

🔗 https://github.com/stolot0mt0m/claude-chromium-native-messaging

Features:

• Automatic detection of Brave, Arc, Vivaldi, Edge, Genspark, Opera, and other Chromium browsers
• Interactive setup script for macOS/Linux
• Creates both Claude Desktop and Claude Code manifest files
• Uninstall option included

Quick start:

git clone https://github.com/stolot0mt0m/claude-chromium-native-messaging.git
cd claude-chromium-native-messaging
./setup.sh

Hope this helps others while waiting for official support! 🎉
