It's been a busy seven days in tech, with ICANN announcing that pretty much any word can be used as a web address suffix and Mozilla launching Firefox 5. Here's the five stories from PC Advisor this week that generated the most comments from our readers.

The five best free parental control programs

Recent research by security firm AVG revealed UK kids aged six to nine years old spend an average of 4.2 hours per week using social networks. The research also nearly half (47 percent) of this age group talk to their friends online but 20 percent have admitted to being bullied online. In a bid to protect your kids when they surf, we came up with a list of five free parental controls software .
Mike Cross revealed OpenDNS was his first choice when it came to secure surfing.
"Available free, and requiring little configuration, it is my first choice. It also imposes no overhead on your PC and applies to all PCs within the household," he said. Meanwhile Lou told said: "To control how many time my kinds spent on PC, I use PC TimeWatch."

Facebook's facial recognition flops

Lately, there's been a lot of buzz in the media about Facebook's facial-recognition technology. But now we've decided to look at the technology itself: Is it as dangerous as we think it is? In the end, Facebook's new face-recognising feature doesn't yet work well enough to pose a significant threat to your privacy.
According to Krinken Rohleder one small detail that FB has perhaps overlooked is that people do not use the tagging system how FB thinks it is used.
"People tag their own children as themselves (often so it comes up on the other parents page). People tag political, social, or just plain funny stuff with their friends names so it comes up for them to see. People use the tagging system entirely differently then FB intended."

Mozilla ships Firefox 5, holds to new rapid-release plan

This week also saw Mozilla deliver the final version of Mozilla Firefox 5 the first edition under the new faster-release regime it kicked off earlier this year.
Dr Blob said: "Months to release v4, weeks to release v5 - seems like a "me-too" approach to keep up with Google Chrome. I wouldn't care if extensions didn't rely quite so much on min/max version numbers..."
Meanwhile, Billmac revealed he doesn't mind the updates but wishes they would stop arbitarily disabling add-ons and try and ensure new versions are capable of using already installed extensions.
"To upgrade to 5 I have to allow it to disable Steganos Password manager - why? Get it right Firefox - we use these extensions because they are useful. At least give us the option to not upgrade (other than killing the download) at our own choice," he said.

New domains for all - so long as you can afford to lose money

ICANN's recent announcement to allow pretty much any word in any language to be used as a suffix to web addresses is another step along the road to an internet dominated by big brands with deep pockets. Like traditional media, in fact. However, Matt Egan believes the new domins will result in businesses losing money.
Sirjohng said: "In a time of worldwide belt tightening to come out with a system like this is mind boggling. However, what is one address above another, it is only a means to a website after all, so let the rich play their little games but for the rest of us, who cares, we get our first address FREE from the ISP and trade away for £150 a year - no contest!

Samsung Chromebook Series 5 to hit UK shelves on June 24

The Samsung Chromebook Series 5, the first laptop to run Google's Chrome OS, goes on sale in the UK today. However, not all of our readers are impressed with the device.
Arlrb said "Until GOOD access to the internet is available EVERYWHERE, pointless."
Meanwhile, Rob said: "The chrome book is such an incoming fail its not a joke. The most useless piece of plastic you will own. For this price you can buy a nice laptop than can do everything you want it to, or even an iPad or Android tablet."
