It’s not often that a browser update makes you want to leave it.
But in this case, a security flaw has put a major dent in the privacy of millions of users around the world.
The issue is known as the WebRTC bug, and it affects Firefox versions 1.9 and later.
The bug lets malicious WebRTS (remote code execution) scripts run in the background and bypass Firefox’s security protections, potentially allowing attackers to read your browsing history, email, and other sensitive information.
There’s no easy fix, though.
Firefox’s default setting to “always keep your data private” means that anyone who tries to do so will be logged out immediately, preventing them from installing new software or changing settings.
If you’re running a custom browser or a modified version of Firefox, there are a few options you can tweak to fix the problem.
Here’s a quick rundown of what you can do to fix this bug.
What can you do to keep your browsing private?
Firefox 1.8.x, 1.7.x and 1.6.x (including the latest Beta version) have a bug that allows remote code execution.
If a malicious WebSider script is running in the foreground, it can then send messages to the browser to take control of your computer.
When you open the browser’s address bar, you’ll see a warning that a WebSiderscript has been successfully executed.
This message, along with a prompt asking you to restart the browser, will tell the browser that it needs to restart its process, or you may be prompted to reboot the machine.
In Firefox 1.5.x you can also turn off the “Always keep your content private” setting, by clicking the “Disable” link in the upper-right corner of the browser window.
You can disable this feature in the settings menu.
What does it do?
The issue affects a wide range of browsers, including those that are based on Microsoft’s Edge browser.
This means that if you’re using a modern version of Chrome, Firefox, or Safari, you might be able to get around the bug by enabling “always private” on the settings.
However, this bug has been known to affect older versions of these browsers as well.
If your browser was based on an earlier version of Microsoft’s Windows, you’re likely to be unaffected.
The only way to get rid of this bug in Firefox is to upgrade your browser to a newer version, which is possible.
You can also disable the “Keep your browsing secure” setting in the Privacy settings of your browser.
The feature is only active in Chrome, Opera, and Safari, so it won’t work on those browsers without an “Always private” feature.
The “Keep Your Content Private” setting was first reported by the security blog CERT on June 24.
