The enlargement of the search bar, yes, surprise!

Starting in Firefox 75, this is the new style when the cursor enters the bar. There's a temporary preference to turn that off in Firefox 75 and 76. In Firefox 77 and later, you'll need to apply custom style rules to tame it.

Hi foxlife1284, Firefox has something like a global scaling factor for the user interface and content. Here's how you can adjust that. Please avoid extreme values that make it hard to recover, like 5% zoom or 500% zoom.

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful.

(2) In the filter box, type or paste devpix and pause while the list is filtered

(3) Double-click layout.css.devPixelsPerPx and Firefox should open an editing field. Here's what the values mean:

  • -1 => uses your system default scaling (e.g., 125% on Windows, 200% on Retina)
  • 1.0 => non-Retina: fonts rendered at 96 pixels per inch
  • 1.25 => non-Retina: 125% zoom (25% enlargement)
  • 1.5 => non-Retina: 150% zoom (50% enlargement)
  • etc.

I suggest starting with 1.5 and see how that size suits you. If it's still too small, try 1.75 and if it's too large, try 1.25, etc. Can you find a value that makes the toolbars/tabs look right to you?

Thank you, I understand what I want to fix. How can I remove the magnification of the search bar when my cursor is there?
