Zen Slack Router von goosebumps

Zen Slack Router opens externally-opened links in the right Zen Browser Space (Firefox container), based on which Slack workspace you were viewing when you clicked the link.

If you belong to multiple organizations, links shared in each company's Slack open with that company's account — no more "you need access" screens from the wrong Google account.

How it works

• Map each Slack workspace to a Space once in the settings page (takes about a minute)
• Links opened from Slack are reopened in the mapped container automatically
• Links clicked inside the browser, unmapped workspaces, and anything opened while Slack isn't running are left untouched

Requirements

• Zen Browser on macOS
• Slack desktop app
• A small companion helper (native messaging) that reads the Slack app's local files — install it from the GitHub repository: https://github.com/yossyl3oy/zen-slack-router
• The Zen setting "Switch to workspace where container is set as default when opening container tabs" must be enabled

Everything stays local; nothing is collected or transmitted.
