MashLogic, provider of a Firefox plug-in for Web content enrichment, just raised $2.5 million, according to peHUB.

Not much else has been revealed about the latest fundraiser, but a glance at what this company is trying to do, it looks like the funds will not be wasted.

With the tagline, “take back the web,” MashLogic is seeking to provide a more personal and content-rich online experience for users who install the plug-in for Firefox. As the next few screenshots demonstrate better than any words can, MashLogic enables users to choose what kinds of supplemental content they want to see on the Web pages they encounter while surfing—company info, music streaming and purchase availability, Wikipedia entries, to name a few categories. The browser extension even allows users to search trends on Twitter.

If you’re interested in testing out the service yourself, MashLogic provides a handy little preview tool on its site.

MashLogic’s business model functions on a fairly simple idea. While attracting users with its content aggregator, the company believes it can help Web operators increase their traffic, both in terms of page-views and time spent. Though there is nothing yet to confirm this, MashLogic might be looking into sharing ad-revenues with these operators.

The Menlo Park, CA-based company first announced in early June that it had raised $500,000. That round of angel funding was provided in part by About.com founder Scott Kurnit as well as Bessemer Venture Partners.

While no investors have been revealed for this latest round of funding, New Enterprise Associates partner Kittu Kolluri and David Cowen from previous investor Bessemer Venture Partners have both been listed as new board members for MashLogic.
