Hi I noticed some strange entries in the Windows Registry yesterday and am a bit wary what they are and where they came from. There all connected to firefox and it seems like an extension of some sort. I only have 3 extensions installed - NoScript, uBlock Origin and Firefox Multi-Account Containers. I attached an image of what I've found. The entries all repeat but with different values for "installtabopened". I don't recall installing anything new recently and apart from the Multi-Account Containers extension. I'm quite paranoid and so scan and check often using different virus / malware tools. Always the worry I missed something though. Any thoughts on this? Thanks for the help beforehand.
