Disable Firefox Domain Sticky Zoom to Reset Zoom Level on Re-Visit
Firefox can zoom in and zoom out on a web pages by pressing Ctrl-+ or Ctrl– keys combination, or by selecting appropriate command in View -> Zoom menu. In Firefox 3, zoom features now magnifies or reduces the size of both text and images.
Beside, zoom function in Firefox 3 also remember the last used zoom level on a domain, and automatically open any web pages from the domain at the zoom level. For example, if you increase the size of text and image on mydigitallife.info by 1 zoom step, Firefox will remember the zoom level. The next time the reader visits mydigitallife.info domain or any page from the domain, the page will be displayed at 1 zoom in step.
If you use zoom function just for temporary reading, and would prefer Firefox to display an new pages at normal zoom or default size, regardless of what the page from the domain is displayed on last visit, here’s the trick to hack the Firefox zoom feature.
Type about:config in the Location Bar. Search or filter for browser.zoom.siteSpecific preference name, then double click on the preference to change its value to false (by default is “true”).
Voila, all new pages on Firefox tab or window now get reset to base normal zoom level.

Thank goodness you posted this information. I noticed this morning that despite a window wash that Firefox remembered something about sites I had visited. I searched an hour trying find out how to turn off site specific zoom. It is a privacy concern and any site specific information should be able to be cleared by the clear private data function. I wonder what other sticky information is in Firefox. But thanks again for your timely information

What I don’t like about changing this preference is that when I zoom on a page and then hit the back button, my previous page is zoomed also. I find that annoying, I prefer to leave this preference as it is.
