Password for your passwords:

Mozilla Firefox allows you to save passwords of websites when you log-in. You can automatically log-in to websites , next time you visit it. All these username-password details are stored in one place. Anyone with an access to your computer can see it. If you get compromised, it would be easy for trackers to get all your information.

You can see your saved passwords in Tools > Options > Security > saved passwords. Anyone can see all your saved passwords from there. By enabling ” use a Master password” , you can create password for the saved passwords list. Confusing? Basically Firefox will ask for a password when you or anyone wants to see saved passwords,every session. It also prevents most of all Third-party software from recovering them.

  1. MY guess is that no one has a plugin for firefox that will fix this security concern

    I have well gone off Firefox after finding that the android version without any plugins is listening in to DLNA broacast messages from devices like XBoxes and Samsung Smart TVs and then making a UPNP request to the devices to recive XML data back from these devices.

    In my case this not only includes the make and model of the TV but also the serial number and its not like my simple android device can stream to the TV or play XBox games.

    I know Google pays Firefox $50m a year and they don’t do that without getting something in return as you can see if you type About:config into the URL and search for Google but I will not put up with Firefox hacking my local area network to then upload all the device data back to central server.

    Shown below is both the request and reply I captured with some of the data replaced using XXX and I also had to tweak the HTML tags in the XML so it would post.

    • I believe it’s a part of new “Send Video To Device” feature. There are no settings to disable it for now but there might be a in-built option to disable it in next Firefox updated version as many users raised same issue as you. Temporary solution would be revert back to older Firefox version as I couldn’t found any plugin for it.Appreciate the comment!
