My limited G4 data allocation is being depleted much too rapidly for my budget. I suspect that the culprit is the web page of a personal weather station (PWS) in which page measurements are updated every ten minutes. I keep a Firefox window open to monitor the web page.
I do not understand the mechanism, but every time I click on the window or tab in which the PWS web page is displayed, I see the latest data, without clicking the Firefox RELOAD button. Thus, it appears to me that the PWS web page somehow is notifying Firefox every time the web page is updated, and that Firefox is automatically loading the update. Is there a way to keep Firefox from automatically reloading this particular web page? Or am I misunderstanding what is happening here? RLH
