Firefox starting page defaults repeatedly

[Tipips]

OK so my problem is simple:
Firefox defaults with seemingly every system restart to the Manjaro page. If I then open Firefox it always shows me try Manjaro.
I want to have the default Firefox page,
I am using this Browser on a Windows Laptop and don’t have Dual Boot (any more)
Is there any way how to fix this without it resetting all the time?

Edit: using KDE Plasma
AMD Ryzen 2700x
AMD Radeon 5700xt

Running Kernel 510
additionally installed 59,54,419

Laptop has a Ryzen 4750u (don’t think its important but just in case)

This can be altered with FF ==> settings ==> Startpage
