I tried to change the font-size of address bar, tabs, sidebar and toolbar using the method given in The method given in: [https://support.mozilla.org/en-US/que.../1239467] gives no change at all of the font-size no matter the value I use. Any ideas? I'm using Windows 10 Firefox 127

You can look at this thread:

  • /questions/1384204 Since the last update, the Firefox screen does not fit my system setting(125%)

If setting browser.display.os-zoom-behavior = 0 doesn't work for you then you can create a new Number pref in about:config and set its value to 100. Paste ui.textScaleFactor in the search bar and select the Number radio button and click the '+' button to add the new Number pref, enter the value (100) and click the blue OK button to confirm.

  • about:config => ui.textScaleFactor = 100

You can open about:config via the location/address bar. On the warning page, click "Accept the Risk and Continue" to open about:config.
