Reproducible: Always Steps to Reproduce: 1. Open 2 tabs 2. Go to tab 1 and use ctrl-'+' twice to zoom in (let's say we have zoom factor of 2) 3. Go to tab 2 4. Go back to tab 1 (zoom factor kept) 5. Use ctrl + mouse-wheel to zoom (in or out makes no difference) 6. Go to tab 2 7. Go back to tab 1 Actual Results: You'll see tab 1 content reverting back to same zoom factor before using mouse-wheel Expected Results: tab 1 should keep the same zoom factor as before leaving tab

Well, I ment cmd-'+' and cmd-'-'.

I confirmed this problem in windows. And it happens in both of the case of full-zoom and the text-zoom. Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1b1pre) Gecko/20080909105611 Minefield/3.1b1pre

Sorry Comment #2 was wrong. Please ignore Comment #2.

I can't confirm this. I didn't "see tab 1 content reverting back to same zoom factor before using mouse-wheel". I tested with today's Minefield nightly on OS X 10.5.4, using both an Apple MightyMouse and a Microsoft mouse-wheel mouse. Note that cmd-+ and cmd-- do a different kind of zooming than ctrl-mousewheel-up or ctrl-mousewheel-down: Cmd-+ and cmd-- tell the browser to zoom the current tab in or out. Ctrl-mousewheel-up and ctrl-mousewheel-down tell the OS to zoom the entire screen in or out.

Hi Steven, with today build I can't reproduce this, maybe it was a "one build" problem. I disagree about mouse zooming as it is stated even on the firefox help page that ctrl-scroll up and down zoom page.

Thanks for letting us know. > I disagree about mouse zooming as it is stated even on the firefox > help page that ctrl-scroll up and down zoom page. Do ctrl-scroll-up and ctrl-scroll-down work differently on your machine than they do on mine (as I described it in comment #4)? If not (if they zoom the entire screen in or out), that's clearly an OS function, not a browser one.

> Do ctrl-scroll-up and ctrl-scroll-down work differently on your > machine than they do on mine (as I described it in comment #4)? Yes. You can set up the keyboard shortcut to enable mouse zoom on OS X System Preferences -> Mouse and Keyboard. I think the default is just ctrl but I changed that to "option-command" so, when I use ctrl-scroll is Firefox to zoom the page content (the window doesn't resize) and not the os.
