Cloud-Synced Firefox Profiles - Automatically Sync Profile Structure Across Devices

[brandonkw123]

Problem Statement

Firefox Profiles are stored locally on each device. While Firefox Sync syncs data within a profile (bookmarks, passwords, extensions), it does not sync the profile structure itself. This means users must manually recreate their profiles on every device where they use Firefox.

This creates significant friction for anyone using Firefox across multiple devices or setting up Firefox on a new computer.

Use Case

This affects any Firefox user who:
- Uses multiple devices (laptop, desktop, work computer) and expects their profiles to follow them
- Gets a new computer and expects their browser setup to transfer seamlessly without manually dragging local files
- Uses profiles for organization (personal, work, family, projects, gaming, etc.)
- Shares a computer and maintains separate profiles for different family members or uses

Current experience:
1. I create "Personal" and "Work" profiles on my desktop
2. I sign into my Firefox Account on my laptop
3. My profiles don't appear - I must manually recreate them
4. I must sign into Firefox Sync separately within each recreated profile
5. I must repeat this process on every device

Expected experience (like Chrome):
1. I sign into my Firefox Account on any device
2. All my profiles appear automatically
3. I select which profile to use
4. Everything is already synced and ready to go

Comparatively How Chrome Handles This (What I would consider industry standard)

Google Chrome allows users to:
1. Sign into their Google account once
2. All Chrome profiles associated with that account automatically appear on every device
3. Select which profile to use
4. Everything syncs seamlessly - no manual recreation needed

This is the standard behavior users expect from modern browsers in 2025.

Proposed Solution

When a user signs into their Firefox Account on any device, Firefox should:

1. Display all profiles associated with that Firefox Account
2. Automatically sync the complete profile configuration:
• Profile name and icon
• All data (bookmarks, passwords, extensions, settings, history, etc.)
3. Allow profile selection at launch or through the profile switcher
4. Optionally allow users to choose which profiles sync to which devices (for advanced users who want device-specific profiles)

Benefits

- Eliminates setup friction: No manual profile recreation on new devices
- Matches user expectations: Delivers the experience users expect from modern browsers
- Supports multi-device workflows: Essential for users with laptops, desktops, work computers
- Simplifies new computer setup: Firefox just works immediately without file transfers
- Encourages profile usage: Users will actually use profiles if they work seamlessly
- Competitive parity: Brings Firefox in line with Chrome's profile management

Why This Matters

In 2025, multi-device usage is standard. Users expect:
- Their browser to work the same way on every device
- New computers to be ready immediately after signing in
- No manual file transfers or configuration recreation

Firefox Profiles are a powerful organizational tool, but their lack of cloud synchronization means most users either:
- Avoid using profiles entirely (losing organizational benefits)
- Manually recreate profiles on each device (wasting significant time)
- Switch to browsers that handle this better

Currently to workaround this, users must:
1. Access about:profiles on each device
2. Manually create profiles with matching names
3. Sign into Firefox Sync within each profile separately
4. Wait for data to sync
5. Repeat for every new device or computer

This is time-consuming, confusing for average users, and feels outdated compared to competing browsers.

Conclusion

Firefox Profiles should sync across devices just like every other aspect of Firefox does. As a user in 2025, I expect that when I sign into Firefox on a new device, my complete browser environment - including my profile structure - follows me automatically.

Please implement cloud-synced Firefox Profiles to bring profile management in line with modern user expectations and eliminate the friction of multi-device Firefox usage.

@brandonkw123 if this aligns with your request, we can merge the threads (and combine the votes) so the conversation stays focused in one space. Just let me know 😃

No way? For real? Hell Yeah

This would be really useful between devices, thanks for suggesting @brandonkw123!
