How to Access Bookmarks from Multiple Browsers in One Place? VertiTab Bookmark Space Subscription Guide
Many people use more than one browser at a time. Chrome might hold all your work bookmarks—project docs, internal tools, frequently used dashboards—while Edge or Firefox is home to your personal collection: news sites, videos, shopping, learning resources. These two worlds stay completely separate, and finding a link from the "wrong" browser means switching apps entirely. It's a constant source of friction.
VertiTab 3.6.0 introduces Bookmark Space Subscription: a way to view bookmarks synced from other browsers under the same account, in read-only mode, directly from the sidebar of your current browser—no switching, no importing.
Install VertiTab from the Chrome Web Store
Two Key Concepts: Sync Space and Follow
Before diving in, two terms are worth understanding:
Sync Space: The fundamental unit of bookmark sync. When a browser joins a sync space, its bookmarks are continuously synced to that space's cloud copy. A single account can hold up to 20 independent spaces.
Follow: When you follow a sync space, VertiTab downloads a copy of that space's bookmarks and displays them in read-only mode in your current browser's sidebar. Following a space doesn't change your local bookmarks and doesn't affect the data in the followed space.
A Typical Scenario
Alex uses two browsers side by side:
- Chrome: joined the "work" sync space, containing work-related bookmarks (project docs, internal tools, frequently used systems)
- Edge: joined the "home" sync space, containing personal bookmarks (news, videos, shopping, learning materials)
Previously, finding a personal bookmark while in Chrome meant switching to Edge. Now, Alex has followed the "home" space from Chrome, and can flip to those bookmarks directly in the Chrome sidebar—clicking any link opens it right there in Chrome. No browser switching. No importing home bookmarks into Chrome (local bookmarks stay separate and uncluttered).
And of course, the same works in reverse: Alex can follow the "work" space from Edge.
Join vs. Follow: Understanding the Difference
| Action | What It Means | Data Direction | Best Used When |
|---|---|---|---|
| Join a space | This browser's bookmarks sync two-way with the space | Bidirectional | This device is a full member of the space; bookmarks stay in sync |
| Follow a space | Download and view a read-only copy of the space's bookmarks | One-way (read only) | You want to browse another browser's bookmarks without merging them |
A simple analogy: Joining is like becoming a co-editor of a document. Following is like getting a read-only copy to reference whenever you need it.
How to Use Bookmark Space Subscription
Step 1: Make Sure Each Browser Has Its Own Sync Space
On each browser you want to access bookmarks from, make sure VertiTab is installed and bookmark sync is enabled (i.e., the browser has joined its own sync space). If not, follow the Bookmark Cloud Sync Guide first.
Step 2: Follow the Target Space from Your Current Browser
- Open the browser where you want to view the other bookmarks (e.g., Chrome)
- Go to VertiTab Settings → Sync → Bookmark Sync
- In the "Available Spaces" list, find the space you want (e.g., Edge's "home" space)
- Click the Follow button
VertiTab will immediately download a local copy of that space's bookmarks from the cloud.
Step 3: Switch Between Spaces in the Sidebar
After following, open VertiTab's bookmark panel in the sidebar. A Space Switcher will appear at the top:
- Select "Local Bookmarks": shows your current browser's own bookmarks, fully editable
- Select "home": shows a read-only copy of Edge's home space bookmarks—you can click links to open them, but not edit anything
Switching is instant—no loading delay.
What the Bookmark Experience Looks Like When Following
Bookmarks from a followed space are displayed completely separately from your local bookmarks in the sidebar—they won't mix into your bookmarks bar or any of your folders. Here's what you can and can't do:
- ✅ Browse the full folder structure and bookmark list
- ✅ Click links to open them in the current browser
- ❌ Edit, delete, or move bookmarks in the followed space
- ❌ Add new bookmarks to the followed space
Keeping the Copy Up to Date
Once you're following a space, whenever that space receives new sync data (meaning the followed browser has updated its bookmarks and synced to the cloud), VertiTab automatically fetches the latest copy in the background. When you switch to that space, you're already looking at the most current version—no manual refresh needed. You can also click the Refresh button at the top of the space view to force an update at any time.
Privacy and Security Design
- Same-account only: Following only works within your own account—there's no way to view another user's bookmark spaces
- End-to-end encryption: All space data is encrypted on-device before uploading; the server can't read any bookmark content
- Space isolation: Each sync space has its own encryption key; data between spaces is completely isolated
- Strictly read-only: Following a space will never write to it in any way—your data is safe

Frequently Asked Questions
Q: Does this feature only work within my own account, or can I view other people's bookmarks?
A: Currently, only bookmark spaces from different browsers under the same account can be followed. Cross-account or cross-user bookmark sharing is not supported.
Q: If I follow someone's—wait, my own—space from another browser, will that browser get a notification?
A: No. Following simply downloads a copy of the space's bookmarks. It doesn't perform any write operations on the followed space, since it's your own data from another browser you own.
Q: How much local storage does a followed space's bookmark copy use?
A: Bookmark data is compressed, so even large bookmark libraries take up very little local storage and have essentially no impact on browser performance.
Q: When I unfollow a space, is the local copy removed automatically?
A: Yes. When you unfollow, the local copy is removed from the sidebar and no longer takes up any local storage.
Q: Will following multiple spaces slow down the sidebar?
A: No. All space copies are locally cached. Switching between spaces is just a display switch on already-loaded data—no extra network requests, and it's very fast.
Q: Can I still see a followed space's bookmarks when I'm offline?
A: Yes. Following stores a local copy, so even without an internet connection, you can still browse the cached bookmark content. You just won't receive any new updates until you're back online.
Q: How many spaces can I follow at once?
A: The combined total of joined and followed spaces is capped at 20, which is more than enough for virtually any multi-browser workflow.
Q: In the sidebar, how can I tell which bookmarks are from a joined space and which are from a followed space?
A: There's a clear visual distinction. Bookmarks from a joined space can be edited normally. Bookmarks from a followed space are marked as "read-only" and can't be modified, preventing accidental edits.
How This Compares to Chrome's Built-in Sync
Chrome's account-based bookmark sync merges all your bookmarks from every device using the same Chrome account into one unified library—essentially one set of bookmarks shared across all devices. It can't:
- Keep a "work browser" and a "personal browser" with their own separate bookmark ecosystems
- Let you browse another set of bookmarks in read-only mode without merging them
VertiTab's space design fills exactly that gap. Different browsers keep their own independent bookmark systems, while still being able to cross-reference each other's content when needed—these two goals are no longer mutually exclusive.
Summary
Bookmark Space Subscription solves a real pain point for multi-browser users: each browser has accumulated a valuable set of bookmarks that you don't want to merge, but do want to access from the other. VertiTab's "join" and "follow" model keeps every space cleanly independent while making it effortless to switch between them in the sidebar.
If you're regularly using both Chrome and Edge (or Firefox), upgrade to VertiTab 3.6.0 and give it a try.
