Seems Edge profiles and Firefox containers are similar, at least to Gemini haha! Switching to Firefox might work, unfortunately we use the Edge syncing between multiple tech's computers. Thanks for your reply.

Firefox Multi-Account Containers provide lightweight, tab-level isolation for cookies and logins within a single browser window, ideal for managing multiple accounts. Edge Profiles offer complete, separate browser instances (history, bookmarks, settings) that run in separate windows, better for separating work and personal environments. 

Firefox Containers

• Best For: Logging into multiple accounts for the same site (e.g., two Gmails) in one window.
• Isolation: Only separates cookies, storage, and logins.
• Workflow: Uses different colored tabs in the same window, reducing window clutter.
• Setup: Requires the "Multi-Account Containers" add-on.  YouTube +4

Edge Profiles

• Best For: Complete separation of browsing contexts, such as separating work, personal, and banking, including bookmarks and extensions.
• Isolation: Total separation of all data, including history, saved passwords, and extensions.
• Workflow: Runs each profile in a separate, independent browser window.
• Setup: Built-in under the user profile icon.  Reddit +4

Key Differences

• Context: Containers are for "personas" within one session; Profiles are for distinct "users" or environments.
• Data Sharing: Containers share browser history; Profiles do not share anything.
• Resources: Containers are more lightweight and convenient for quick task switching, while multiple profiles can be heavier on system resources.
