Firefox-3.0 zoomed images and webpages

what dpi does your X server indicate?

please, post output of:

 xdpyinfo | grep resolution

snaker@cornelius:~$ xdpyinfo | grep resolution
  resolution: 148x148 dots per inch

I'm having a similar problem in Hardy--the whole interface (menubars, toolbars, websites, etc) is zoomed. Ctrl+- takes care of webpages, but I cannot figure out what wrong with the interface. I've tried installing a theme (I usually use the default), deleting ~/.mozilla, and tried running as a new user--no luck. Firefox 2 was fine, but the latest update to Hardy completely replaced this with 3.

This problem has been around for quite some time (see https://bugs.launchpad.net/ubuntu/+source/firefox-3.0/+bug/188652/), and is now really annoying since FF3 is the default browser for Hardy. I guess annoying is good: it means that more and more people will complain until it is fixed.

For what it is worth, the FireFox 3 Full Page Zoom feature is the subject of considerable debate on the Mozilla forums.

Hopefully, Mozilla will give us a way of letting us change the default zoom. I'm in the camp that considers the default zoom way too much.

Noel, its the same but very much seroiusly for me

This bug also affects me. Laptop system, running at 15 inch widescreen running at 1920x1200, dpi 148x145.

FF3 will be too annoying to use until this bug is fixed for me. I have no interest in lowering the DPI, because it makes most things unreadable unless absurd font sizes are used.

Ditto here. The bug effects me using 1920x1200 147x147 pixel resolution. I'm running a font resolution of 92dpi. Anything smaller than that and it becomes nearly unreadable on this 15.4" laptop display. You'll see that every portion of the GUI is nearly doubled in size with the exception of the text in the interface... but the fonts on the loaded web pages are blown out of proportion. I have the same issue on my desktop with FF3 using two 1680x1050 monitors at 104x86 pixel resolution, but it's nowhere near the same level of magnification.

I have the same bug and it's really annoying. It seems to come from proprietary nvidia drivers. Switching to nv driver fix the issue.

A little more info about my laptop:
HP Compaq nw8240
15.4" widescreen
1920x1200 native resolution
Graphics reported as ATI Mobility Radeon X700 (can't remember what it really is)
Currently using Fglrx 8.542.1 (Catalyst 8.1), will install 8.2 and see if that helps.

Thanks, Andrew. From your report, we can see that it isn't an nVidia driver specific issue, and Jean's report says to look for a difference in behavior between the nVidia driver and the nv driver, which can be checked against the behavior of the ATI driver.

My system is a T61p (1920x1200 w/ nVidia FX750M using the nVidia driver).

I can guarantee it's not graphics card specific. The screenshot I posted above is using an Intel 915 graphics chipset. The problem is in the resolution/dpi mathematics somewhere. The fonts are correct in the GUI, but not on the rendered web page. Also, the graphics are blown out of proportion through the entire application.

I dont know exactly why but its now fixed for me :)

I did:

sudo dpkg-reconfigure -phigh xserver-xorg
sudo nvidia-xconfig (comment: to activate nvidia propietary driver)
mv ~/.mozilla ~/.mozilla.old (comment: firefox artwork was correct but webpages was smaller than normal, after of this all works fine)

And now all works fine for me

now :
snaker@cornelius:~$ xdpyinfo | grep res
  resolution: 111x111 dots per inch

> its now fixed for me.

Not for me. I followed your steps:

  # sudo dpkg-reconfigure -phigh xserver-xorg
  # sudo nvidia-xconfig
  # mv ~/.mozilla ~/.mozilla.old

restarted gdm, and saw exactly the same, oversized, firefox rendering.

Try changing your layout.css.dpi setting from -1 to 0 in about:config.

I also tryed eSe fix, but it did not work, I have still the broken layout.

xdpyinfo | grep res
  resolution: 147x145 dots per inch

Given what I have read until here, this problem seem to come from people using a 1920x1200 resolution (I am also using this resolution).

I confirm that when I change my screen resolution to 1600x1200 (resolution: 122x145 dots per inch) or to 1600x1024 (resolution: 122x124 dots per inch), firefox is displayed correctly (text and icons).

No, that doesn't work. 0, -1 and 146 all result in bad rendering. However, I discovered (and later found confirmation in Bug 178558) that DPI around 96 resulted in reasonable rendering.

Changing the layout.css.dpi setting to 96 in about:config also fix rendering for me! Thanks for the fix Noel.

just the same problem shown by https://bugs.launchpad.net/ubuntu/+source/firefox-3.0/+bug/191791/comments/7

 xdpyinfo | grep resolution
returns

(as a test, i installed firefox-2 and it worked fine)

Confirming the rendering Bug on Hardy Final. Changing the layout.css.dpi Setting to 96 works for me - thanks!

Alexander, on March 10, 2008 you marked this bug as a duplicate of bug
#175904. Why? I can't see how this bug is related to bug 175904.

this should be fixed by now. We don't scale unless we reach ~192 dpi anymore.

what dpi does your monitor have?
