There are some problems with my Firefox 22.0 since yesterday. It started to show websites' text too large, had to use Ctrl and "-" every time I accessed any website. However, things how text looked in FF menus did not change. My actions: 1) FF forums. Opened config, searched for that numbers - there they were, unchanged. 2) control panel-->screen resolution-->Make text larger or smaller-->set to 100% 3) Monitor set to 75 Hz (no higher values) and True Color (32 bit)

PC responded I needed to log off. Turned PC off, then turned on. Everything started to look small (text on a browser kind of hard to read), but hooray - websites are normal again. Tried to use 125% - no, websites are displayed wrongly big again.

edit: My WIn7 did not find any updates for monitor; same for Nvidia video card. WIndows updates are all installed.

Problem about disproportion between text in FF menus and website text still appears. Would be very gratefull for any solutions.

Code changes regarding HiDPI support for high resolution displays have landed in Firefox 22 and later (bug #844604).

You can modify the layout.css.devPixelsPerPx and increase or decrease the value in 0.1 or 0.05 steps to adjust the size of fonts and other elements in Firefox. 

   The layout.css.devPixelsPerPx pref is a String value parsed to a float and allows to fine tune the dimensions of all elements (user interface and web pages) more precisely (resolution 0.1 or 0.05). 

   Change the default value -1 to 1 to make it work like in previous Firefox versions (100%)

Start with a value of 1 and adjust this value with 0.1 steps or 0.05 for finer adjustments. 

   Use values between 1.0 and about 0.5 to reduce elements in size (do NOT go all the way to 0.05!)
   Use values greater than 1.0 to magnify and make elements larger (percentage divided by DPI, % / DPI).

If web pages needs to be adjusted after changing this pref then you can look at the Default FullZoom Level or NoSquint extension. 

   Default FullZoom Level: https://addons.mozilla.org/firefox/addon/default-fullzoom-level/
   NoSquint: https://addons.mozilla.org/firefox/addon/nosquint/

Use this extension to adjust the font size for the user interface:

Hello,

Firefox on Windows is now following display scaling options which may render text larger on high resolution displays. You can adjust your screen resolution. To modify it do the following:

  1. Type about:config into the Firefox address bar and tap on the Enter key.
  2. If the warning This might void your warranty appears, click I'll be careful, I promise.
  3. Search for layout.css.devPixelsPerPx
  4. Double-click on layout.css.devPixelsPerPx to modify its value. The default is -1.0 in Firefox 22 and above. Change it to 1.0 to make it work like in previous Firefox versions.

If necessary, further adjust the value in 0.1 or 0.05 steps. Use values between 1.0 and about 0.5 to reduce elements in size. Use values greater than 1.0 to increase size. For example, a value of 1.25 will increase font size to 125% to accommodate the default DPI setting in Windows 8. Double check the value that you enter. Setting a too small value will make everything disappear and a too large value will blow things up.

If web pages still need to be adjusted then you can look at the Default FullZoom Level or NoSquint extension.

To adjust the font size for the user interface, you can use the Theme Font & Size Changer extension.
