Another reason to distrust Microsoft
Microsoft has been slipping in an extension for Firefox which is installed without the user’s approval. It cannot be uninstalled via the usual way of uninstalling extensions and it modifies the user agent of the browser (how the browser identifies itself).
Why the hell are they tampering with third party software?! They have no business interfering with other software on your system. This pretty much proves that if you do not run a F/OSS operating system, your computer does not belong to you. They have the ability to tamper with any software that they choose when you run their operating system.
Move to an operating system that respects your right to not have a tampered system.
Fuck Microsoft.
