The new computer works perfectly well now. Except for two areas which I have managed to fix, I think.
One I certainly have. As you know, I am occasionally involved in blogging, just very occasionally mind. But Firefox would not remember me. If I closed Firefox, that is the browser window or restarted the computer, I was forgotten. This meant constant logging in to sites, including my blog, blog reader, blog comments, porn sites etc etc.
I sought info on the net and it came good. I am not sure why I had to do this to make Firefox work like it used to on the old computer, but I went to my Firefox profile via the run option, pasted in a long address I found at another site, renamed something like squilcookies to tempcookies and it worked. Firefox now remembers me at my own site and yours too. It was getting very laborious to log in to so many sites to make a comment.
The other problem was computer forgetting power saving options. We never turn the computer off, only restart but it is set to shut down the hard drive and monitor after five minutes of no usage. About once a day it just forgets the setting and stays on and we took to turning the monitor off. To get it power saving again, I change the settings to three minutes and restart. When it happens the next time, back to five minutes and restart.
I started writing the above several days ago and all seems well now, including the power saving options. I have no idea why that has started to function properly. Maybe the same cookie problem.
