Since having Firefox update I have a oversized picture, larger than my screen? How do I downsize it?

with any page I go to the site covers more than my monitor size and as a result I have to use the bar at the bottom of the page to see the extreme right. This seemed to happen when I got a Firefox update,,,,

Hi oranji, you can zoom out manually then. As you know, Firefox remembers your preferred zoom level on a site-by-site basis.

I don't think Microsoft is driving this; Apple's Retina display is the pioneer of High DPI. But both IE11 and Chrome 30 are expected to move in the same direction as Firefox 22. Maybe they will make it easier to tweak the settings than Firefox does?

As for long loading times, you could start a new thread on that.

Check whether your zoomed that particular website

  • To reset the size back to normal, press Ctrl and 0 at the same time.

You can also use the NoSquint. add-on to change the default zoom level for all websites at once. After setting your global zoom level, you can still fine-tune the zoom on individual sites.

Hello tarty1

Firefox on Windows is now following display scaling options which may render text larger on high resolution displays. You can adjust your screen resolution. To modify it do the following:

  • Type about:config into the Firefox address bar and tap on the Enter key.
  • If the warning This might void your warranty appears, click I'll be careful, I promise.
  • Search for layout.css.devPixelsPerPx


  • Double-click on layout.css.devPixelsPerPx to modify its value. The default is -1.0 in Firefox 22 and above. Change it to 1.0 to make it work like in previous Firefox versions.

If necessary, further adjust the value in 0.1 or 0.05 steps. Use values between 1.0 and about 0.5 to reduce elements in size. Use values greater than 1.0 to increase size. For example, a value of 1.25 will increase font size to 125% to accommodate the default DPI setting in Windows 8. Double check the value that you enter. Setting a too small value will make everything disappear and a too large value will blow things up.

If web pages still need to be adjusted then you can look at the Default FullZoom Level or NoSquint extension.

To adjust the font size for the user interface, you can use the Theme Font & Size Changer extension.

Did this fix your problems? Please report back to us!

Thank you.

This method does not correct the problem for me.

I have already used nosquint and found settings I liked that didnt ruin page interfaces by having text too large for the tabs, etc etc.

However if I use 1.0 in that setting, the entire firefox interface shrinks back to normal.

I want the UI to be the "inflated" size, but no text/video/image stretching. Really, the text doesnt bother me. Its quite nice. However, it stretches everything.. making youtube videos and images blurry messes. Please correct this.

Hi derpinheimer, you marked your last post as the solution, so you might not need any further replies. But as long as I'm posting, if you want to change the font size in the UI independently from the content, there is a different extension for that: Theme Font & Size Changer.

Thanks very much jscher2000!

This solves my problem :)

Ideato's solution worked to restore my website view to what I'm used to - thanks for the very clear instructions. However, the text in my menu bar, my bookmark toolbar, and on my tabs (page titles) is undersized. Is there something separate in config that controls the text size on the menu/bookmark bars?

I'm annoyed with Mozilla for abruptly making this change that screws up everything AND that the fix apparently involves multiple components. I'm running enough extensions as it is (I can go have lunch in the time it takes FF to load them all), so I really don't want to install another to manage a non-broke thing that got badly fixed. Setting FireFox to any kind of Windows "standard" seems extremely ironic in light of the history of IE. Seriously?!

Hi oranji, if you don't want to use Theme Font & Size Changer to enlarge the fonts on the menu, toolbars, and tabs, you can apply style rules using either:

  • a userChrome.css file or
  • the Stylish extension (if you already run it)

For example:

@namespace url(http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul);
#main-window, .menubar-text {
  font-size:16px !important;

That's not a complete solution because there are many different parts of the UI that need to be styled, but you get the idea.

Why would I manually restyle a whole browser when there are so many other browsers available? I've been loyal to FF for years , despite aforementioned sloooooow loading, because it's a hassle to change, but if it's going to be just as much of a hassle to keep it...

Not to mention that Mozilla has now added yet another set of variables to the endless list of browser-specific tweaks I have to make to the various websites I maintain, whether I use it myself, or not. FF hasn't made a mistake this big since they decided saving a bookmark to one folder should eliminate it from all other folders.

As it turned out Ideato's fix did not resolve all the display issues in webpages. On Craigslist, for example, the navigation links at the bottom of the page were cut off. Other sites were too big, and I found myself having to constantly zoom in or out to get sites to fit in the window. Combined with the text resizing in the user interface, this was just too much mess to clean up.

I rolled back FireFox to vs. 21.0. Mozilla recommends against this because they publish the security holes in each previous version after they release an upgrade (coercive much?), but MANY people are having this problem and doing the same, so I suggest it is the FF developers that need to fix this problem, instead of foisting it off on each and every individual end user to reconfigure a version that should never have been released in this condition. Keeping my fingers crossed that this is fixed in the next release.

There's a Mozilla page on downgrading (http://kb.mozillazine.org/Going_back_to_an_older_version) that is somewhat complex, but other users posted that they simply went to the previous versions page and installed the old version over the new one (http://windowssecrets.com/forums/showthread.php/155292-Firefox-22-Giving-Me-Nightmares-How-to-roll-it-back). This worked for me. Version 21.0 is the first file on this page: ftp://ftp.mozilla.org/pub/firefox/releases/21.0/win32/en-US/

I did install the 3rd party Mozilla Backup utility for Windows users (http://mozbackup.jasnapaka.com/download.php - it's free) and back up my profile first, just to be on the safe side, but all my settings carried over intact, and I didn't have to use the backup. Hope this is helpful to others with the same problem.

Oh, just got update to firefox (to ver. 22) and everything looks AWFUL! Fonts and pics are HUGE! Zoom - Reset doesn't help, because it seems to be some kind of neat new feature. (yeah right!)

Fix above (about:config - layout...) doesn't help, it change EVERYTHING smaller - not only the text/pics.

So did i really got it right: if Im going to use Firefox still, i need to install this and that addons to make this looks like earlier version? Seriously!? Well, im going back to 21 and waiting that someone fix this back like it was from this terrible new feature. Thanks anyway!

Edit.' Installed FF 21 over 22 and problem solved for now... "This worked for me. Version 21.0 is the first file on this page: ftp://ftp.mozilla.org/pub/firefox/releases/21.0/win32/en-US/" Thank you for this!

Hi mreni, for future reference, Zoom > Reset resets to the default level.

In Firefox 21 and earlier, that default is 96dpi. In Firefox 22, the default is based on your Windows zoom level, which for many people is 120dpi (125%). You can override that in about:config.

To zoom smaller than the default level, use Ctrl- to zoom "out".

Is this issue fixed already or is FF22 still the same - oversized everything?

Hi mreni, Firefox 22 has not had any intermediate updates. The next release will be Firefox 23. I haven't seen anyone mention changes to how High-DPI support works in Firefox 23; the release notes should become available on August 6th.

Oh... Well, I'll stick on FF21 then :)

I've had same problem since updating to FF22, I'm considering that it's a FireFox's problem. I'm using other browsers for time being..just less headache!

Seems to be unavoidable with Firefox, another update means another stupid change. Updating Firefox is one of those dreaded things for me because I know there will be something new to fight.

This time some genius decided images shouldn't appear in their actual size pixel for pixel (devs will love that idiot for that one), no despite the feature to zoom the default will now be having the image stretched, unrelated to the zoom level just to top it off. Nevermind the confusion and time wasted just to find out it's a good old Firefox "improvement" at it again, to add insult to injury it takes an about:config edit and 2 extensions to undo this nonsense and it still isn't completely undone.

Editing layout.css.devPixelsPerPx in about:config to "1" corrects the images being warped and blurred but now you have a GUI for ants, enjoy straining your eyes, thanks FF.

So from there extension 1 Theme Font & Size Changer to increase the font on tabs to at least make them readable, oh but guess what, it will only result in the font size being increased and not the Tab, so you could end up with only a few letters on the Tab, great.

So extension 2 TabMix Plus so you can define the minimum size of Tabs, great, the GUI is becoming usable again, or some of it anyway. Since this doesn't correct the size of icons on the Toolbar, you sitll have a Toolbar for ants even with the option of "use small icons"

Well done morons at Firefox for the past few years, the only consistency in Firefox has been stupid decisions, messing up things that were fine before with no innovation worth mentioning.

Hell and to think the only real alternatives are Chrome and IE, only thing more sad is that Chrome is starting to look more tempting than ever and gets used increasingly more often (I have to keep them all installed for testing). Firefox is becoming rather backwards and crappy, only thing keeping me hooked is extensions until their features are available on Chrome.

Hi Mozzyy, I certainly empathize with the objection to blurry toolbar icons.Hopefully someone will introduce some new preferences to Firefox to handle the chrome area differently than the content area.

Lots of users zoom websites, including users like me with a 14" screen at 1600x900. The days of safely assuming a 96ppi display are long past.

Both Chrome 30 and IE 11 are expected to be DPI-aware applications. I imagine they will benefit from having had Firefox go first, and will give users a smoother path.

Has anyone with this problem tried the new update (version 24.0) that was released a couple of weeks ago? Am wondering if this has been corrected in the latest update - it didn't appear to be on the list of things fixed.

more options

Hi oranji, Firefox 24 has the same basic approach to HiDPI support as Firefox 22 and Firefox 23. Some tweaks probably have been made for specific glitches, but I think you would need to try it in your specific environment to know whether those fixes make a difference for you.

Thanks for the info, jscher2000. I'm not really up for experimenting if it means I may have to roll back again. Doesn't Mozilla realize how extremely hostile this change has been for people with vision issues?? Somehow I assumed they thought about things like that, but I was obviously mistaken.
