Firefox modules in about:third-party disappeared
Hello,
i recently want to check something in Firefox and noticed that in about:third-party where some modules were installed. I have no knowledge about these kind of stuff. There were like up to 10 modules with the sign that there were not signed.
So I wanted to check it on the next day. But these modules disappeared now.
The questions are: Is it normal that these modules disappear? Is it normal that some module are unsigned?
Thanks for help!

But is it common that there were unsigned modules in it. And if not, how did they get there and how do they vanished?
It's not common for Windows to run unsigned code, period. And some security software also makes it difficult.
What I see on about:third-party are 3 Intel display driver DLLs and 2 security software DLLs. These were all preinstalled on the system by other software, and aren't part of Firefox itself.
Those DLLs seem logical. If you see anything that makes you wonder "What the..." then you definitely would want to run some malware scans. This article lists tools other Firefox users have found helpful: Troubleshoot Firefox issues caused by malware.
I notices that the modules come and go, depands on the Websites. Is it a common behaviour?
Is there a way to trace die non-listed modules? Maybe in the Firefox Data or something?
I confess I've never looked at that list before, so I don't know what is normal there. The support page at Identify problems caused by third-party modules in Firefox for Windows describes how to use the page but doesn't mention what to expect. That said, why would anything else be listed there -- what reason would that program have to inject code into Firefox's memory space?
