When I start Firefox (Or Librewolf) they start lagging a lot in start but with time they start responding smoothly (in like 3to5 minutes).What could be problem? How to fix that?
Edit : Do not know how but it is working now. Edit2 : Experiencing Same issue again 😞 !!
As others have said, it sounds like a slow disk. Can you share more information?
I have 128GB SSD and my system is installed on it. 2 gb ram and core2duo (It was working fine on it). Issue is on all gecko browsers and not on any other.
