Firefox 16 removed from installer page after vulnerability found

Mozilla is working on a fix and plans to ship updates on Thursday.

Mozilla has temporarily removed Firefox 16 from the current installer page after it found a security vulnerability in the new version of its browser, it said on Wednesday.

The vulnerability could allow a malicious site to potentially determine which websites users have visited and have access to the URL (uniform resource locator) or URL parameters, Michael Coates, director of security assurance at Mozilla said in a blog post.

Mozilla does not however have any information that the vulnerability is currently being "exploited in the wild," he added. It is working on a fix and plans to ship updates on Thursday.

Firefox 16 has been temporarily removed from the current installer page and users will automatically be upgraded to the new version as soon as it becomes available, Coates wrote.

Firefox version 15 is unaffected, and as a precaution users can downgrade to version 15.0.1. Or they can wait until Mozilla's patches are issued and automatically applied to address the vulnerability, Coates said.

The new version of the browser was released on Tuesday and addressed a number of security vulnerabilities, including some considered critical.

Firefox had a 20.08 percent share of desktop browsers in September, compared to 53.63 percent share for Internet Explorer and 18.86 percent for Chrome, according to Web measurement company Net Applications.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
