Firefox Support Forum

Every time Firefox updates itself, all of the text and images and page layouts become huge. I have tried every single fix that is usually suggested for this issue:

Zoom out with scroll wheel: Makes text smaller (and images, if I disable zoom text only) but does not fix page layouts (ex. Google search still has a horizontal scroll bar, even in full screen.)

layout.css.devPixelsPerPx: No effect at all. Can be made bigger at values over 1.0, but not smaller.

Compact mode: Sizes down the toolbar, but nothing in the webpages themselves.

Refresh Firefox: Still huge.

Safe Mode: Still huge.

Disabled all extensions: Still huge.

Complete uninstall with all leftover system files removed with RevoUninstaller, then reinstall: Still huge.

Other browsers: Display correctly. Absolutely no issues with size, including Firefox forks like Librewolf. (See attached image for direct comparison between the two browsers.)

I can temporarily alleviate the issue by using a restore point on my computer from about a week ago but when I opened Firefox this morning, it bumped me to an update page, and everything was huge again.

I was previously using a non-native screen resolution while I was recovering from surgery in bed and the screen was too far to see at 1920x1080. But I did not have this problem for two months of recovery. It started just a couple days ago. Returning the screen to its native resolution has not resolved the issue. Firefox, and only Firefox, is still enormous.

Firefox has worked fine on my WinX systems for years. Yesterday it downloaded a new version (103.0 64-bit) that totally destroyed the experience!

Everything I see now is GIANT SIZED compared to the rest of my desktop and to the old Firefox. I've looked for any relevant setting and I've tried the "Refresh" button with no help.

I want to go back to the previous version!

I don;t know if I chose the right "best describes the question" because the first half of the option is off the screen to the left, and there's no way to scroll over. I would like to go back to the version that preceded this latest update please. It worked well. Please reply by email, [email-removed], because I can't read most of what's on the screen here. I hope someone pays attention to this, because otherwise I'll have to abandon Firefox, and it's been by far my preferred browser. Can't think what you've done to it. Your updates in the past all worked fine. I'm on a Lenovo ThinkPad S145 with Windows10.

As the title says, I cannot get MP4 files to play in Firefox, which renders several websites unusable. These sites work in Edge just fine, but I cannot get them to work in my preferred browser. Everything is up to date, and I have all the codecs I could ever need installed, as well as the Windows N Media Feature Pack. The browser has been tested several times in troubleshooting mode, and I've even gone as far as running Windows in safe mode with networking to try to isolate the issue. I cannot get it to work at all. This is the 2nd device I've had this issue on, and it's driving me up a wall.

Any help or advice would be greatly appreciated.

Firefox 103.0 (64-bit) Windows 10 Pro N 21H2 19044.1865

I have followed the fixes. It will work after I "Refresh Firefox" but goes back to not working again. Should I reinstall Firefox? How do I add this site to the exceptions? Thank you

Hmm. We’re having trouble finding that site.

We can’t connect to the server at www.cdc.gov.

If that address is correct, here are three other things you can try:

   Try again later.
   Check your network connection.
   If you are connected but behind a firewall, check that Firefox has permission to access the Web.

Hello

I have just updated firefox 103.0 64bits on my pc windows 10. And bigs bugs : all web pages became huge zoomed at around 150 - 160% !

I managed to fix the huge zoom problem by installing this firefox extension : https://addons.mozilla.org/fr/firefox/addon/zoom-page-we/?utm_content=addons-manager-reviews-link&utm_medium=firefox-browser&utm_source=firefox-browser

and setting all web pages to 90% zoom with it. But this is not a solution because firefox has to fix this bug since this update! :(

And the toolbar has become much higher, which decreases my screen height, it was better before! :( See my screenshot where i circled in red the height of the toolbar which has become higher! :(

even the tab bar has become higher! :( i managed to reduce it a little in height thanks to a code that i inserted in the file userChrome.css ,but the result is not beautiful : the texts are too flush with the line ( see my screenshot where i circled in blue the tab bar that i reduced with code in userChrome.css )

So I have never had a problem with YouTube up until yesterday, anytime I try to watch a video and click play or anywhere on the video it just has a circle that spins in the middle around a youtube button, or sometimes just a black screen.

I have tried clearing Cookies & Cache, tried in safe mode, tried with a new profile, disabled hardware acceleration, I even uninstalled and re-installed Firefox.

Still for some reason I am unable to watch videos and only on Firefox, it works fine in Chrome and Edge browsers.

I am at a loss on how to fix this, and I really don't want to have to use two browsers for watching videos and navigating the internet.

Any Ideas?

Also my Internet is not the problem, I have Gigabit Fiber.

FF upgraded itself and turned off the lighted keyboard on my tower computer. I can still use the keyboard, but it is not backlit and I want that feature back. Windows help files are non-existant. I have unpluged the keyboard and reconnected it and I did a cold reboot of the computer-no joy. Disabling the keyboard and trying to reinstall it by plugging it in again might work, but doing that is marked "advanced" by windows, so I am afraid to do it without advice. I am running windows 10 and use a Logitech keyboard. I am not a computer techi, so I need advice in baby-talk. VO1TV>

Discord hyperlinks will no longer open when Firefox Developer Edition is selected as my default browser. They open fine in both Firefox, Microsoft Edge, and Google Chrome when selected as Windows 11's default browser. When selecting my default browser it would show 2 instances of Firefox Dev but after uninstalling then reinstalling it there is only one instance in the default app list. I'm not really sure where to go from here. Maybe this is an issue with the latest version of Dev Edition or is this an issue with my Windows?

Thanks
