Ok, things I have noticed.
On the random freeze that a reboot is the only way out...
This happens when I navigate to a new website... And that website opens another, supplementary window. Sometimes just a tab, sometimes a whole new window. Sometimes obvious, but most time invisible.
This is not a supplementary window that I have given permission for, or asked for. The site does it itself.
Also, last night, I had a bunch of random smaller freezes. Finally, all of a sudden, I couldn't get onto any of the sites I regularly visit. It just sat there forever, saying it was connecting.
Then, after closing the browser, and then opening it again, I discovered I could go to the sites, but all the cookies were gone, and I had to log in again on those sites.
Last night was the clincher. I believe I know the reason behind all of this.
Lookit, I may sound stupid because I am an old man, and I can't rattle off all the technical details, like an 18 year old tech student. Or clearly explain what I think may be happening, well enough to make others actually understand what I am trying to describe. That doesn't mean that I AM stupid, or that what my gut is telling me is happening... is just paranoia.
I don't know if this will work or not. But it's what I am going to try. Better than doing nothing, because I am marginalized and told I am imagining things.
