I use Firefox and have it open 24/7 with 20 tab pages. I use an extension called Tab Mix Plus, which allows me to set all of the tabs to automatically refresh every 5 minutes (I want to set it to 1 minute). My internet can handle the bandwidth. My question is: are there any detrimental effects to my computer because of this? What goes on every time I visit a page or refresh a page (for example, does my hard drive get filled up with bits and pieces of a web page such that I will need to use CCleaner to remove them frequently in order to keep my computer optimized)? Will it put a strain on my hard drive as a result?
Are there better ways to accomplish "real-time updates"?
