![]() ![]() We have experimented with tab unloading on Windows in the past, but a problem we could not get past was that finding a balance between decreasing the browser’s memory usage and annoying the user because there’s a slight delay as the tab gets reloaded, is a rather difficult exercise, and we never got satisfactory results. ![]() Firefox is now better at surviving these situations. And of course, there are the tab hoarders, (no judgement here). Or perhaps those users simply trying to play a memory-intensive game or using a website that goes a little crazy. We believe this may especially benefit people who are doing heavy browsing work with many tabs on resource-constrained machines. Unloading tabs allows Firefox to save memory leading to fewer crashes and avoids the associated interruption in using the browser. On Windows, out-of-memory (OOM) situations are responsible for a significant number of the browser and content process crashes reported by our users. The tab’s scroll position and form data are restored just like when the browser is restarted with the restore previous windows browser option. When a tab is unloaded, the tab remains in the tab bar and will be automatically reloaded when it is next selected. This feature is currently enabled on Windows and will be deployed later for macOS and Linux as well. Mozilla developers were deeply unimpressed after a data sanitization process of the Mozilla Developer Network (MDN) site database failed, which resulted in the accidental disclosure of MDN email addresses of about 76,000 users and encrypted passwords of about 4,000 users on a publicly accessible server.Īnd in 2013, Mozilla had to send a British spyware pusher (Gamma International) a cease and desist letter, after a report showed how the surveillance software was being delivered under the guise of a Firefox executable.Starting with Firefox 93, Firefox will monitor available system memory and, should it ever become so critically low that a crash is imminent, Firefox will respond by unloading memory-heavy but not actively used tabs. ![]() This time last year for example Mozilla admitted to a serious data breach of its developer details. ![]() This is not the first time that Mozilla has suffered a security scare. Mozilla meanwhile has notified relevant law enforcement authorities of the breach. The latest version of Firefox apparently fixes all the vulnerabilities the attacker may have learned. We have no indication that any other information obtained by the attacker has been used against Firefox users.” “We believe that the attacker used information from Bugzilla to exploit the vulnerability we patched on August 6. “The account that the attacker broke into was shut down shortly after Mozilla discovered that it had been compromised,” it blogged. It is also limiting the number of ‘privileged access’ users. All users that have access to security information have had to change their passwords and use two-factor authentication. The open source foundation also said it was making improvements to Bugzilla to beef up the security of its products, developer community and its users. However the site has promised it had now “taken several actions to address the immediate threat.” Bugzilla Flaw Mozilla has conducted an investigation of this unauthorised access, and we have taken several actions to address the immediate threat. “We believe they used that information to attack Firefox users. “We are disclosing today that someone was able to steal security-sensitive information from Bugzilla,” said Mozilla in a blog posting. Mozilla has admitted that hackers stole security-sensitive information from Bugzilla, the company’s bug tracker system, and used it to “attack” Firefox users. ![]()
