I've installed ad blocker but for some reason they wouldn't always block some of those little ads on various forum websites. I have in the past edited the host file to reject certain servers. However since I've re-installed the OS a few times I forgot to save a copy of the host file and just forgot about it. Websites such as ebay and others often take information and connect to other websites in the backgound. I'm not certain if there is a program that could monitor a website and provide a url list. To keep a particular website running well and to prevent running scripts and making connections to other websites and urls may be difficult and time consuming. One other problem I come across when web surfing under Vista x64 is everything starts to bog down because the latest version of Firefox 52 starts to hog memory requiring more than a gig memory. So I need to shut down firefox, clean and reduce the PC's memory using a memory cleaner the restart FireFox. You then can pull up a past history and select which urls you want to load. I'm uncertain if Windows 7, 8 and 10 have this same type of problem running on more recent pc architecture. I first started using a PC back in 1981 and eventually purchased my own 8 bit computer running CP/M 2.2 with 64k memory and a 4mhz Z80 cpu. Early pc's in many ways were faster than many modern GUI PCs as there was no graphics overhead. Back in those days computers was sorta in the dark ages as much of the general population often thought about computers the same as they thought about astrology. Computers were at one time often considered to be esoteric and different from other things in mainstream society. However I new people who owned and/or used computers, some were business owners while other worked as scientists, a few worked for Microsoft, etc. I belonged to a computer club where we would meet a few times each month to talk over using, repairing and upgrading PC's. Anyway since purchasing my first PC back in the early 80s I've been upgrading PC's ever since. Back in those days Microsoft a new startup was worth around ~$50,000.00 and trying to get a contract with IBM. Started connecting to the Internet or Intranet approx. the same time and had dialup account using a 150 baud modem that connected to a VAX mainframe, that was connected to the Intranet. In comparison to todays Internet consisted of few people and organizations worldwide.
