Firefox used to give me lots of room in the window, with icons the size of a pencil eraser and room to see 5 or 6 tabs across the top and all of my bookmark folders across the window. The zoom setting for content in the windows was 100%. I now have icons the size of my finger, room to see 3 tabs, the zoom set to 67%, and even with the window full screen I cannot see all of my bookmark folders. How to I get the old window settings back? I have no idea why the size definitions changed, and no idea how to reset it.

It's not you, it's Firefox... Firefox 103 now applies the Windows "Make text bigger" setting as a zoom multiplier (Release Notes).

Your options:

(A) If you do not need "Make text bigger" for other applications, the simplest thing you can do is reset that to 100% to resolve the issue:


(B) Firefox 103 has 3 interrelated hidden settings that control the overall zoom level and whether it considers information from the system. This one seems to be working for many people to revert the change:

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

More info on about:config: Configuration Editor for Firefox. The moderators would like us to remind you that changes made through this back door aren't fully supported and aren't guaranteed to continue working in the future.

(2) In the search box in the page, type or paste ui.textScaleFactor and pause while the list is filtered.

Normally, Firefox will display a bar with Boolean Number String and a plus button. If Firefox displays a row that already has a number value, skip to step 5.

(3) Click the circular button in front of Number and then click the + button to create a new preference. (See composite screenshot below.)

(4) Firefox should display an editing field, and show a value of 0 -- edit the value to 100 then press Enter or click the blue check mark button to save the change.

(5) If the current value of ui.textScaleFactor is NOT 100, then double-click the preference to display an editing field, and change the value to 100 then press Enter or click the blue check mark button to save the change.

Hi

While there is not an easy way to revert this our product team did suggest this about:config preference change as the optimal solution at this time.

  1. In the address bar, type about:config and press the Enter key.
  2. The about:config warning page may appear. Click Accept the Risk and Continue to continue to the about:config page.
  3. In the search field, enter browser.display.os-zoom-behavior, select the pencil "edit" icon and change the number to 0.
  4. Select the check mark and restart Firefox.

They did note they would look into alternative options which may be present in a future update.

WARNING from the moderator team: Changing Firefox pref from the about:config page can sometimes break Firefox or cause strange behavior. You should only do this if you know what you're doing.
