Fix UI Scaling and Large Fonts Issues in Firefox 103 and Later Versions

1. Due to the update I’ve rediscovered “make text bigger” and “make everything bigger” which I had set so long ago that I forgot they were in Windows settings. I had set to make reading easier (eye issues); it worked and I forgot about until this update scrambled up webpages.

   I’ve been trying to get back to “normal” w/o success.

   I’ve done Solution: Tabs, toolbar menu etc are tiny & difficult to read. I need these larger w/o making webpages a mess. The FF update appears to have affected Excel and possibly other things I use.

   If FF103 is now using Windows settings to alter (mess up) websites, what settings should we have in Windows?

   OR: Is there a way to disconnect FF & Windows so that I can make text/everything larger w/o making websites close to useless (everything huge & too much scrolling).

   I’m NOT a tech person & not sure I understand all the issues. thanks for your help.

2. ^^ Did you try other solutions given above?

3. Thank you for this. I moved over to Waterfox when this “update” happened as the sizing drove me crazy using a 150% increase on a large screen monitor. Now I’m back to normal after following your excellent instructions and can once again enjoy Firefox proper and all timely security updates.

4. Thanks, #1 solution was simple, and worked like a charm!

5. YES Ty you’re my savior
   This was always a pain after every update, each time you got to find a different solution. I mean why don’t put a tickbox follow windows scaling. Thats a basement instead of forcing it.

6. Solution 1 worked. Thank you so much! I thought I was going to have to go back to Chrome. I appreciate you creating this blog post.

7. Thank you so much for providing a solution. Larger fonts and icons were really a difficulty with my 13 in screen.

8. Personellement, j’ai trouvé une autre solution : j’ai modifié la taille des polices de base dans Firefox en 16 – 14 – 12.
   Et là, Je suis revenu à des pages avec des tailles à peu près normales.

   Translation:

   Personally, I found another solution: I changed the base font size in Firefox to 16 – 14 – 12. And there, I returned to pages with roughly normal sizes.

9. Thank you!!!

   I just updated FF and wondered what the hell just happened. Solution 1 was an instant fix.

10. Works great, Thanks a lot

11. Adding the ui.textScaleFactor setting and using a value of 100 worked for me; however, I’ve noticed that I still need to readjust the zoom on some web pages and a few pages still don’t look exactly the way they did previously. But it’s ok. Firefox needs to reverse the zoom changes they made with this update!

    For those who find the tab and menu bar too small after adding ui.textScaleFactor set at 100, I suggest you try changing the number to a smaller number. A user on the forum mentioned he was using a different value, so I experimented with other values and found that larger numbers made the menu smaller and lower numbers made the menu larger. The value of 100 still works best for me, but if your menu, tabs, etc., is too small, perhaps try a value of 90 and if that’s not exactly what you want you can experiment with other values.

12. Thank so much for sharing your expertise, and for figuring out alternative solutions so quickly after FF103 release. I tried options 2 and 3, and settled on the last with setting 0.8.

13. Thank you sir!! Solution #1 was fast and easy. Greatly appreciated! Now I can sleep tonight.

14. THANK YOU! This was driving me crazy! Solution 1 did it. Thank you!!

15. Hello,

    is there a problem to fix the Windows accent color in the title bar of FF 103?

    In FF 102 I was successfully using

    .titlebar-color{
color: -moz-accent-color-foreground;
background-color: -moz-accent-color;
}

    in my userChrome.css, but this does not work anymore.

17. When I changed the number in os-zoom:
    0 was minisucle
    1 is what its set to
    as suggested I tried 2 and bingo! it worked. Thank you

18. I can’t thank you enough for this clear and concise solution to a very annoying issue.

    You are the best! 🙂

19. Thank you so much for this! I was about to uninstall Firefox forever. What were the devs at Mozilla thinking??

20. Thank you. Thank you. Bless you! Been happily using FF for years but this latest Mozilla change was just too much to bear, until a friend led me to your site!

21. Thank you for not only providing the solution, but also describing the cause of the problem. Extremely well-written, thoughtful, and the instructions were easy to follow. Best of all, Solution Number 1 worked perfectly. Again, thank you for your efforts.

22. why didn’t Firefox fix the problem them selves as soon as they were made aware of it ?

    and what problem is going to be next ?

23. Excellent Knowledge VG ! Thanks, it solved the issue.

24. Finally someone with a real solution that at last fixed my problem.
    Thanks a lot
