Mozilla Launches 'Firefox Private Network' VPN Service as a Browser Extension

Mozilla Launches 'Firefox Private Network' VPN Service as a Browser Extension

Sep 11, 2019
Mozilla has officially launched a new privacy-focused VPN service, called Firefox Private Network , as a browser extension that aims to encrypt your online activity and limit what websites and advertisers know about you. Firefox Private Network service is currently in beta and available only to desktop users in the United States as part of Mozilla's recently expunged "Firefox Test Pilot" program that lets users try out new experimental features before they were officially released. The Firefox Test Pilot program was first launched by the company three years ago but was shut down in January this year. The company now decided to bring the program back but with some changes. "The difference with the newly relaunched Test Pilot program is that these products and services may be outside the Firefox browser, and will be far more polished, and just one step shy of general public release," said Marissa Wood, vice president of product at Mozilla.

Multiple Vulnerabilities in Firefox for Android Leak Sensitive Information

Multiple Vulnerabilities in Firefox for Android Leak Sensitive Information

Mar 27, 2014
The Android operating system has hardened its security with application Sandboxing features to ensure that no application can access sensitive information held by another without proper privileges. Android applications communicate with each other through Intents and these intents can be abused by hackers to provide a channel for a malicious application to inject malicious data into a target, potentially vulnerable application. Security Researchers at IBM have discovered multiple vulnerabilities in Firefox for Android platform that allow a malicious application to leak the sensitive information related to the user's profile. Android's Firefox app stores the personal data at following location: / data /data/org . mozilla . firefox /files/mozilla/<RANDOM-STRING >. default . Where the random name for user's profile is used to prevent unwanted access to this directory in case of Firefox exploitation. Researchers developed an exploit to brute-force the...

How to Speed Up Firefox With Multi-Process, If It's Not Working By Default

How to Speed Up Firefox With Multi-Process, If It's Not Working By Default

Jun 19, 2017
After years of waiting, Mozilla last week launched Firefox 54 for Windows, Mac, Linux, and Android, with multi-process support — a "major improvement" to improve your browsing experience — but many users are still struggling to take advantage of this feature. Mozilla's multi-process support in Firefox has been in development for over eight years as part of a project, codenamed Electrolysis or E10S, which aimed at improving responsiveness and speed by streamlining memory use by different processes. Describing the latest release as the largest change to Firefox code ever, Mozilla says it has worked hard to avoid increased memory consumption, and slower performance, as Firefox now uses up to four processes to run web page content across all open tabs. In other words, Firefox is finally making use of "significantly less RAM" of your computer, as heavy web pages in one tab will now have a much lower impact on responsiveness and speed in other tabs. ...
Firefox OS for smartphones, incredible platform for Developers

Firefox OS for smartphones, incredible platform for Developers

Feb 11, 2013
Mozilla’s Firefox OS, the mobile operating system from the company that makes the Firefox browser build entirely on open web standards and having ability to beat Android or iOS.  Firefox OS is Mozilla's ambitious attempt to build an operating system that brings more openness to the walled gardens of Apple's iOS and Google's Android. New Operating Systems for Smartphones Its a new mobile operating system built entirely using open web standards and with codename  Boot to Gecko , means a Linux distro that automatically loads Gecko or in more simple words apps for Firefox OS are basically just websites written in HTML, JavaScript, and CSS. The Web is the Platform, which means not only taking down barriers, but also a lighter system that makes your apps run smoothly and an optimal battery life. Firefox OS written with basic HTML, CSS, and JavaScript Mozilla has also added some extra hooks to Firefox OS that allow developers to access a phone’s hardware v...
Firefox Web Browser Now Blocks Third-Party Tracking Cookies By Default

Firefox Web Browser Now Blocks Third-Party Tracking Cookies By Default

Jun 04, 2019
As promised, Mozilla has finally enabled "Enhanced Tracking Protection" feature on its Firefox browser by default, which from now onwards would automatically block all third-party tracking cookies that allow advertisers and websites to track you across the web. Tracking cookies, also known as third-party cookies, allows advertisers to monitor your online behavior and interests, using which they display relevant advertisements, content, and promotions on the websites you visit. Which makes sense as no one likes to waste time in watching advertisements and offers that are not of one's interest. However, since tracking cookies gather way more information without requiring users' explicit permissions and there is no control over how companies would use it, the technique also poses a massive threat to users' online privacy. To limit this extensive tracking, Mozilla included the "Enhanced Tracking Protection" option as an experimental feature in Octo...
Firefox Send — Free Encrypted File Transfer Service Now Available For All

Firefox Send — Free Encrypted File Transfer Service Now Available For All

Mar 13, 2019
Mozilla has made it easy for you to share large files securely and privately with whomever you want, eliminating the need to depend upon less secure free third-party services or file upload tools that burn a hole in your pocket. Mozilla has finally launched its free, end-to-end encrypted file-transfer service, called Firefox Send , to the public, allowing users to securely share large files like video, audio or photo files that can be too big to fit into an email attachment. Firefox Send was initially rolled out by Mozilla to test users way back in August 2017 as part of the company's now-defunct "Test Pilot" experimental program. Firefox Send allows you to send files up to 1GB in size, but if you sign up for a free Firefox account, you can upload files as large as 2.5GB in size. The service uses a browser-based encryption technology that encrypts your files before uploading them to the Mozilla server, which can only be decrypted by the recipients. Unlike popul...
Firefox Browser vulnerable to Man-in-the-Middle Attack

Firefox Browser vulnerable to Man-in-the-Middle Attack

Sep 19, 2016
A critical vulnerability resides in the fully-patched version of the Mozilla's Firefox browser that could allow well-resourced attackers to launch man-in-the-middle (MITM) impersonation attacks and also affects the Tor anonymity network. The Tor Project patched the issue in the browser's HTTPS certificate pinning system on Friday with the release of its Tor Browser version 6.0.5 , while Mozilla still has to patch the critical flaw in Firefox. Attackers can deliver Fake Tor and Firefox Add-on Updates The vulnerability could allow a man-in-the-middle attacker who is able to obtain a forged certificate for addons.mozilla.org to impersonate Mozilla servers and as a result, deliver a malicious update for NoScript, HTTPS Everywhere or other Firefox extensions installed on a targeted computer. "This could lead to arbitrary code execution [vulnerability]," Tor officials warned in an advisory. "Moreover, other built-in certificate pinnings are affected as wel...
Firefox to Automatically Trust OS-Installed CA Certificates to Prevent TLS Errors

Firefox to Automatically Trust OS-Installed CA Certificates to Prevent TLS Errors

Jul 02, 2019
Mozilla has finally introduced a mechanism to let Firefox browser automatically fix certain TLS errors, often triggered when antivirus software installed on a system tries to intercept secure HTTPS connections. Most Antivirus software offers web security feature that intercepts encrypted HTTPS connections to monitor the content for malicious web pages before it reaches the web browser. To achieve this, security software replaces websites' TLS certificates with their own digital certificates issued by any trusted Certificate Authorities (CAs). Since Mozilla only trusts those CAs that are listed in its own root store, the antivirus products relying on other trusted CAs provided by the operating system (OS) are not allowed to intercept HTTPS connections on Firefox. In recent months, this limitation continually crashed HTTPS pages for many Firefox users showing them SEC_ERROR_UNKNOWN_ISSUER, MOZILLA_PKIX_ERROR_MITM_DETECTED or ERROR_SELF_SIGNED_CERT error codes when their an...

UPDATE Firefox and Tor to Patch Critical Zero-day Vulnerability

Dec 01, 2016
The critical Firefox vulnerability being actively exploited in the wild to unmask Tor users has been patched with the release of new browser updates. Both Mozilla and Tor Project has patched the vulnerability that allows attackers to remotely execute malicious code on Windows operating system via memory corruption vulnerability in Firefox web browser. Tor Browser Bundle is a repackaged version of the open-source Mozilla Firefox browser that runs connections through the Tor anonymizing network configured to hide its user's public IP address. However, the exploit code released by an unnamed online user was currently being exploited against Tor Browser users to leak the potentially identifying information of Tor users. "The security flaw responsible for this urgent release is already actively exploited on Windows systems," an official of the anonymity network wrote in an advisory published on Wednesday.  "Even though there is currently...no similar explo...

Sep 04, 2019
Mozilla has finally enabled the "Enhanced Tracking Protection" feature for all of its web browser users worldwide by default with the official launch of Firefox 69 for Windows, Mac, Linux, and Android. The company enabled the " Enhanced Tracking Protection " setting by default for its browser in June this year, but only for new users who downloaded and installed a fresh copy of Firefox. Remaining users were left with options to either enable the feature manually or wait for the company to activate it for all users. Now, the wait is over. With Firefox 69, Enhanced Tracking Protection will automatically be turned on by default for all users as part of the "Standard" setting in the Firefox browser, blocking known "third-party tracking cookies" and web-based cryptocurrency mining scripts. Firefox 69 By Default Blocks Known Third-Party Tracking Cookies Cookies are created by a web browser when a user loads a specific website, which helps...

Mozilla Updates Firefox Terms Again After Backlash Over Broad Data License Language

Mar 01, 2025 Privacy / Data Protection
Firefox browser maker Mozilla on Friday updated its Terms of Use a second time within a week following criticism overbroad language that appeared to give the company the rights to all information uploaded by users. The revised Terms of Use now states - You give Mozilla the rights necessary to operate Firefox. This includes processing your data as we describe in the Firefox Privacy Notice . It also includes a nonexclusive, royalty-free, worldwide license for the purpose of doing as you request with the content you input in Firefox. This does not give Mozilla any ownership in that content. A previous version of this clause, which went into effect on February 26, said - When you upload or input information through Firefox, you hereby grant us a nonexclusive, royalty-free, worldwide license to use that information to help you navigate, experience, and interact with online content as you indicate with your use of Firefox.

Firefox Browser to Enable Controversial HTML5 DRM to Stop Piracy

Firefox Browser to Enable Controversial HTML5 DRM to Stop Piracy

May 16, 2014
The Music Industry, Movie Studios and other companies who create media contents are always concerned with people getting access to their content without paying for it. Last year, On Request of Big Tech companies such as Microsoft, Google and Netflix, The World Wide Web Consortium (W3C) defined a new API (Application Programming Interface) called ' Encrypted Media Extensions (EME) ' in HTML5 to aid web-based video services in restricting the rights of users who utilize their services. Now the companies won't need to rely on third-party plugins like Flash and Silverlight to deliver copy-protected movies and TV shows to your browser. Instead, now they have same capabilities of Digital rights management (DRM)  right into the fabrics of the web. All other major modern web browsers, including Internet Explorer, Chrome, and Safari are supporting  Encrypted Media Extensions (EME)  within the web browser since last year, except Mozilla Firefox . Even after criticizing the use...
