Zoom one window without zooming all Windows?

Unlike Internet Explorer 6, apparently Firefox 3 can zoom pictures at
the same time it zooms text. Here, I usually open the picture in a new
window. It's no big deal, but can the picture window be zoomed without
automatically zooming all of the other Windows at the same time? Can
one window be zoomed without zooming all of the other Windows? I'd
rather just close the window, instead of having to zoom out after
zooming in. Thanks.

 

Zooming is site specific by default.
See <http://kb.mozillazine.org/Browser.zoom.siteSpecific>,
and try it by changing the pref to false in about:config

That works here.

 

I was talking about stopping pop-up windows from changing the main
window zoom setting.

I think this is how it goes...

Enter this in your browser address bar.

about:config

Then make sure this setting is True.

browser.zoom.siteSpecific

Also, if you don't want pop-up windows to change the zoom of the
main window, like when you are looking at a picture that you want
magnified more than usual, make sure this setting is False.

browser.zoom.updateBackgroundTabs
