My Firefox has got inconsistently large font size in some UI, namely on the homepage (text elements with style "font: caption") and texts in the Update Firefox notice box (which I don't know how to reproduce within a resonable time and effort). It just happened after a ordinary restart of Firefox: no updates etc. I tried updating Firefox after that but to no avail. How can I fix it?

Can you attach a screenshot?

You may have accidentally zoomed webpage(s). Reset the page zoom on pages that cause problems.

  • View -> Zoom -> Reset (Ctrl+0/Command+0 (zero))

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

Note that you appear to be using Firefox Beta or Developer Edition (119.0). Does this also happen with the current release?
