While going through the web browsing, annoying adverts get on your nerves and you are unable to do anything to get rid of them except closing them again and again. Sometimes, these advertisements are very useful in some context, but often, they are annoying and of course, you would like to find out a way to get rid of them.
Well! What you can do is to select an extension or app to block website ads. It is also necessary for you to get because, the appearance of these adverts can make your system slower down and thus, the website, you want to open will be also loaded slowly. It is incredibly irritating when you find yourself helpless before them.Read more
Firefox has a big problem with the way its intermediate certificate cache works because it can be tricked into leaking information to misconfigured servers, basically fingerprinting users even if they're using Private Browsing.
Security researcher identified the data leak, the issue could allow attackers to identify browsers operating in a sandbox for malware analysis and tell them apart from those used by regular people. The way this works is that when starting a TLS session for HTTPS, a server that is configured correctly sends a visiting browser the intermediate CA and its server CA. A misconfigured server only sends the server CA and this sometimes happens with Firefox.Read more
There's a zero-day exploit in the wild that's being used to execute malicious code on the computers of people using Tor and possibly other users of the Firefox browser. According to security researchers who analyzed the code, it exploits a memory corruption vulnerability that allows malicious code to be executed on computers running Windows.
The malicious payload it deliversis almost identical to one that was used in 2013 to deanonymize people visiting a Tor-shielded child pornography site. The FBI ultimately acknowledged responsibility for the exploit, which was embedded in webpages served by a service known as Freedom Hosting.Read more
Mozilla officials say they'll release a Firefox update that fixes the same cross-platform, malicious code-execution vulnerability patched Friday in the Tor browser. The vulnerability allows an attacker who has a man-in-the-middle position and is able to obtain a forged certificate to impersonate Mozilla servers, Tor officials warned in an advisory.
From there, the attacker could deliver a malicious update for NoScript or many other Firefox extensions installed on a targeted computer. The fraudulent certificate would have to be issued by any one of several hundred Firefox-trusted certificate authorities.Read more
Adobe’s Flash technology is on its way out of the Firefox internet browser. In August, Mozilla Corp., maker of the browser, will begin defaulting to HTML 5 instead of Flash for video, online animations, games and other rich media.
If users run into a website where there is no non-Flash option available, Firefox will still render that site in Flash. But next year, Firefox will ask for permission before it renders any sites in Flash or Microsoft Corp.’s Silverlight, a rich-media technology similar to Flash. Web browser plugins, such as Flash and Silverlight, “often introduce stability, performance, and security issues for browsers,” said Benjamin Smedberg, a manager of Firefox quality engineering, in a blog post.Read more
Over the past decade, there's been a privacy arms race between unscrupulous website operators and browser makers.
The former wield an ever-changing lineup of so-called zombie cookies that can't be easily deleted and attacks that sniff thousands of previously visited sites, while browser makers aim to prevent such privacy invasions by closing the design weaknesses that make them possible. Almost as soon as one hole is closed, hackers find a new one. Over the weekend, a researcher demonstrated two unpatched weaknesses that Web masters can exploit to track millions of people who visit their sites.Read more
Earlier this month, it was reported that hackers managed to breach the bug database of Mozilla. From here, the attackers accessed 185 non-public bugs for the popular Internet browser Firefox, 53 of which were categorized as severe vulnerabilities.
At least one of these has been used in the wild, against visitors of a Russian news site. Now, it might not just be Mozilla’s non-public bugs that are under threat. A security company has discovered how to obtain high-level permissions on Bugzilla, the vulnerability database used by Mozilla as well as a host of open-source projects and private businesses. These databases contain all sorts of sensitive information.Read more
Mozilla engineers have revealed that their bug tracking application was compromised, and an unknown attacker had used a privileged account which had access to sensitive information about unpatched Firefox vulnerabilities.
According to the foundation's security disclosure, they confirmed the attacker had access to the bug tracker since September 2014, but they suspect access goes back even further, to September 2013. Mozilla security experts blame this incident on one of its users that had reused the bug tracker's password on another site, which was later hacked. The company's bug tracker, which is named Bugzilla and is also available as open source, is the instrument which the foundation uses to track problems with its software.Read more
The mob is turning against Flash. Mozilla has blocked every version of Adobe’s Flash plugin from running within its Firefox browser, while Facebook’s head of security has called for Adobe to kill it off.
The moves come following a series of vulnerabilities in Flash being actively exploited, including those exposed by the Hacking Team compromise. Firefox users seeking to view Flash-based content, such as videos, adverts or more complex web tools for uploading images and other actions, will need to click again and accept a warning that “Flash is known to be vulnerable. Use with caution”. That means users of Firefox cannot use Flash by default.Read more
Mozilla is starting a new initiative that the company says is designed to incorporate more privacy enhancing features into Firefox and the other Mozilla products. The project involves collaboration and will involve Mozilla running a group of high-speed Tor relays, as well.
Privacy has become a major issue for users across the spectrum, not just the security conscious or paranoid. Nowadays, consumers are seeking out privacy enhancing tools and shunning those that infringe on their expectations of online privacy. Especially the NSA revelations of the last 18 months also have helped make privacy a key concern for enterprises and their customers.Read more
