Why zooming in Windows 7 changed also the font size in Firefox?

I have win7 and I tried to change the text/icon size from the windows to 125%. It also affected everything in firefox (text in tabs, address bar etc., not the text on the pages which you can change with ctrl +/-).I changed it back to 100% and everything became really tiny. How can I make it standard size no matter what zoom I use in windows itself.

Have you had experience from this kind of problem before?

Chosen solution

You can try this:

  1. Open the Properties of the Firefox desktop shortcut (right-click: Properties)
  2. Go to the Compatibilities tab
  3. Put a mark before "Disable display scaling on high DPI settings" to see if that has effect.

You can use an extension to set a default font size and page zoom on web pages.

How did you zoom the entire interface along with the contents?

I got it as I wished with Theme Font & Size Changer. Other ides that cor-el introduced didn't help for this problem.

finitarry: I used windows own zoom ability for the text and icons in windows desktop. Firefox was only unwanted victim of the effect. Problem was that I could not reverse it to the original size.

You can see in those pictures the top bar/text size as it was before the solution.

I just had the VERY same experience, also caused by the Win 7 font size change, which was subsequently restored to its original settings, and here, too, only FF 11 was affected by the change...

I'm reluctant to add yet another add-on. Are there no settings in the about:config page that can be changed to control this?

Following an advice on this forum, I tried changing the following on the about:config --

layout.css.devPixelsPerPx

from 1.0 to larger. This changes the spacing of the *areas* of the tool-bars and the Bookmarks column, but not the font size. Is there no settings that controls font size???
