ContextVault
A cross-browser extension that brings Firefox-style identity containers to Chrome, Edge and Safari and uses AI to suggest which 'bucket' a new tab belongs in — so social media managers, freelancers and privacy-minded users get the same separation on every browser.
Social media managers and freelancers who juggle multiple client and personal logins across browsers and devices
- AI tab-classifier that proposes the right container as you open new tabs
- Cloud-synced containers that travel with you across Chrome, Edge and Safari
- One-click 'switch identity' button that re-opens the same URL in a different bucket
- Per-container cookie/storage export for clean handovers between teammates
Firefox 153 just promoted containers to a first-party feature, validating that identity isolation is a mainstream expectation — but creators and freelancers working in Chrome can't use it, and that's where most agency work happens.

Crowded market — SessionBox (paid, established), multi-containers.com (free Chrome port), GoLogin, MultiLogin, Sendwin, Island, and Facebook Container all compete for the same identity-isolation use case; only the AI-suggestion layer is novel.Chrome Multi-Account Containers | Free SessionBox Alternative ↗Firefox Multi-account Containers Alternatives ↗
Proven willingness to pay — SessionBox runs tiered plans from $4.99–$8.99+/month (Hobby/Professional/Teams/Corporate), and multi-containers.com validates a freemium funnel in this niche.Sessionbox: Details, Pricing, Features, & Integration in 2026 ↗SessionBox Antidetect Browser Review 2026: Pros and Cons ↗
Privacy and multi-account work are durable trends (creator economy, agencies) and Firefox elevated containers to first-party status, but native browser profiles and built-in Chrome profile switching threaten extension-based approaches over time.Firefox Multi-account Containers 2026: Review & Pricing ↗
Cross-browser extension APIs (MV3, WebExtensions) and AI classification are well-trodden ground — SessionBox demonstrates the model is buildable — though MV3 service-worker limits and Safari quirks add real engineering cost.SessionBox review 2026: Honest look at its features & limits ↗
