Firefox collections are groups of related add-ons assembled for easier sharing. This idea was launched from the Firefox Add-ons site several months ago. Since some time has passed, I thought it might be interesting to check back in with this online Mozilla feature to see which collections are the most popular out there.
Here are the most popular add-on collections for the Firefox browser:
Windows 7 Theme for Firefox 3.5
32430 subscribers – This collection of add-ons were gathered to help you make Firefox 3 more seamless in the Windows 7 operating system. Not only do you get the nice theme and tweaking add-ons, but you also get some great time conserving tools too!

It would not make any sense to have an add-on collection without having a collector to collect them with. Alongside the new collections feature on the Firefox Add-ons site – there is an extension to go with it. The Mozilla Firefox Add-on Collector will help you discover and organize your favorites into easy to manage collections.
Along with the new Firefox Add-ons web site, the people at Mozilla also treated us to a new feature called collections. What are they? Well, they are a group of related add-ons that are assembled for easy sharing.
