Frequently Asked Questions

What people are saying about Clusters

"I have used almost every tabbing available on the firefox add-on's network. Cluster tabs is the best I've ever experienced. It's easy to manage your tabs into clusters and retrieve them whenever you want."

"Wonderful tool for research purposes, where you have multiple sources of information. Now you can wrap them all together and share them with your colleagues.

Also great to group my 'frequently visited' web sites so I can access them easier and faster."

"NEVER add reviews to ANYTHING. But in this case, I have to. This is absolutely the most useful add-on I have used in ages. If you sometimes have masses of tabs open at a time like I do (sometimes 100+ in a window) this add-on will be a godsend to you. I love it!"

"It's very easy to learn and use and it has really helped me to cleanup my tabs and it allows me to access the sites that I cluster quickly, and easily."

Does the add-on keep track of my browsing?

No it doesn't. Browsing history is only stored in your software in the same way as Firefox normally does. There is the additional capacity to remove clusters-specific history from your browsers memory by clicking the down arrow icon (next to orange button) and selecting 'Clear Menu'.


When I add a tab to Clusters does it also add the tab history?

Yes but only on your browser, other people see just one link of the page you added, they do not see the history you have in the tab you added.

On your browser only, when you add a tab to a Cluster Tab, your browser remembers the history, in other words you're really just putting the tab away for later rather than closing it.


When I add a tab am I creating a copy or editing the page?

You automatically create a copy, you will see a yellow box telling you the new cluster you've created, you'll be able to edit the title and description too.


Can I collaboratively edit a cluster with someone else?

No, at least not at the moment, but this feature is on our roadmap. This feature will arrive when we launch personal cluster tabs. Instead for now, each time you add something to a cluster tab that was created by someone else, a copy is automatically created.


Do links in a cluster contain other peoples history?

No, when you load a cluster for the first time the tab links on its index page will not have any history associated with them. Your history will be added to them within your browser only when you start to use them but no one else will see it.

This means that many people can view the same cluster, but when you browse from links in the cluster they open in new tabs and browsing history is then added to the new open tab. If you then close the new tab and re-open it later from the cluster's page again, the tab will load and retain your history.


How do you record history in Cluster page links I use?

The add-on handles the history, it's not held by the webpage/server. To explain, the add-on keeps track of all tabs using unique IDs, opening and closing tabs from a cluster tab effectively hides and shows them. The actually tabs uses the normal history mechanism of Firefox.


Do tabs in a cluster tab take up memory?

No, as soon as you add/return a tab to a cluster tab it stops using your web browser software (Firefox) memory, for example: Flash site music will stop playing.


Can I merge clusters?

Yes, you can add a cluster tab to another cluster tab - if you do all the tabs from the cluster you are adding go into the cluster you are adding to.


How do you make money?

We show contextual advertising in the right hand side of every cluster page, we hope these ads will be relevant enough to add value and interest to people who are viewing the cluster. When these ads are clicked on we get a percentage revenue share.


Do you have a product roadmap?

Yes we do, there are four stages for the product:

1. Public & anonymous (Completed)

2. Private & personal with password protection (Completed)

3. Public & personal - addition of user registration, cluster streams, search by person, and group editable clusters (pending)

4. Published - addition of keyword based URLs e.g. clusterurl.com/mashable (pending)


Do you have a support forum?

Yes, we use the Get Satisfaction service, you can visit the cluster support forum here.
