Replaced old computer because it kept freezing, not loading, and saying "Firefox is not responding". Person who works on computers told me it was probably my hard drive since it was older. Found good buy, replaced computer. Loaded only new files, not many. Don't have pictures or play games or etc. Did not transfer from old computer anything. Same thing is happening . Usually keep 3 programs open during the day that I have used for years. Can't transfer between programs because they take so long to load. This is a Lenovo and I have run all the stuff that Lenovo website runs. Hardware, mother board and all the other features and it shows that the computer is good. No issues. Really like Firefox and have used it for years, but this is so puzzling. Have tried alot of the things suggested for Firefox issues and nothing has solved this problem, Find it curious that same problem on both computers. Running latest Version of Windows 10. HELP
