We aim to help people improve their web browsing experience by reducing the amount of tabs they need to keep open.

The cluster tabs add-on for Firefox works with our free web service that generates a unique and anonymous public web page address for each cluster tab created.
Create public cluster tabs around subjects that make sense to you while effortlessly reducing the number of tabs you need to keep open.
There is no registration to use the free web service or add-on so have fun clustering!
We've produced Cluster tabs for what we consider to be the best web browser.
If you do not wish to use Firefox, we've produced a form that enables you to create a very basic clusterURL (no thumbnails or tab functionality)
Create basic cluster
Public cluster tab pages have a visual (thumbnail) index of the tabs within them.
There's no longer any need to keep tabs open for 'later'. Instead, effortlessly drag and drop tabs into each other to create cluster tabs.
Add as many tabs into one 'cluster tab' as you like based on reasons that make sense to you. For example, cluster about a new purchase, property hunt, holiday or work/study project.

Any closed cluster tab can be reopened from the drop down menu from the clusters button

In addition to dragging and dropping tabs into each other, you can also add a new tab to any cluster tab by clicking the "+" icon.
This will enable you to add it to any cluster tab ready to retrieve later or share with friends.
Close tabs with confidence and get rid of your web browser tab clutter.
Re-open any tab from a cluster tab index and you will notice that it has retained your browsing history from where you left off, this means you can use the back button to visit pages you viewed before you closed the tab last time.
Tabs opened from a cluster tab have an arrow 'back' icon (as above) in place of [x] close.
Instead of closing the tab you'll be returning it back to the cluster it came from complete with any browsing history you've generated.
Technical note: Browsing history is not stored online and is not viewable by anyone else.
Share unique ClusterURL links automatically made for every Cluster tab.
Web authors can cut/paste HTML widgets found on all clusterURL index pages to display the cluster title and web address (& number of views in the JS widget) on their sites.
Post any Cluster Tab plus comments directly to Twitter, Facebook, Myspace, friendfeed or Mozillaca.
"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."
