Font size and zoom - increase the size of web pages

Font size and zoom - increase the size of web pages

 

 

The zoom controls allow you to increase or decrease either the size of a whole web page or just the size of all the text in order to improve readability. We'll explain how it works.

Zoom in and out of a website

Here's how you can zoom in and out of individual websites.

  1. Click the menu button New Fx Menu on the right. The customization menu will open and you will see the zoom controls at the top.
    Zoom 29 - Win8 Zoom 29 - Mac Zoom 29 - Linux
  2. Use the + button to zoom in, and the - button to zoom out. The number in the middle is the current zoom level - click it to reset the zoom to 100%. You can also see the current zoom level in the address bar:
zoom fx51
Keyboard shortcuts: You can also use the zoom controls without a mouse. Press and hold commandCtrl while pressing + to zoom in, - to zoom out, or 0 to reset.
Tip: To set the default zoom level for all websites, try the NoSquint Plus add-on.

How to only change the size of the text

Instead of changing the size of everything, you can just change the size of the text.

  1. Press the Alt key to temporarily bring up the traditional Firefox menus. On the menu at the top, click View, then go to Zoom.
  2. Select Zoom Text Only. This makes the controls only change the size of text; not images.

Set a minimum text size

You can set Firefox to automatically display all text at a minimum font size. If a web page contains text that is smaller, Firefox increases the font size of the text to this minimum.

  1. Click the menu button New Fx Menu and choose Options.Preferences.
  2. Select the Content panel.
  3. In the Fonts & Colors panel, click Advanced....In the Fonts & Colors section, click Advanced....
  4. In the Minimum Font Size drop-down, select the minimum size in pixels in which all text must be displayed.

  5. Click OK to save your changes.
Alternate method: If you're unable to access your font settings through the menu button, type about:config into your address bar. Search for the font.minimum-size preference and change the value to 0.

In Firefox 4, there are now toolbar buttons for page zoom. That needs to be added to this article.

Re: Font size and zoom - increase the size of web pages

I came up with a section about using the toolbar to zoom in and out, and had to include how to get the zoom items in the toolbar before explaining how to zoom in and out using them. It needs review. As I was writing it, however, I thought about some of the following:

  • Are the toolbar items platform specific?
  • That section could definitely benefit from some pictures, as there isn't too much text involved in the process.
  • Is {button +} and {button -} the correct markup for the magnifying glass icons that appear in the toolbar?

Re: Font size and zoom - increase the size of web pages

Your button markup looks OK to me but where do you see "magnifying glass icons"?

Also, you only need {for fx4} for the new section (not {for fx5, fx4}) since {for fx4} now means "show for Firefox 4 and above".

Just a thought, you might want to add a link to Customize Firefox controls, buttons and toolbars for people who want more information about toolbar customization.

P.S. You also asked, "Are the toolbar items platform specific?". What do you mean? What OS are you using?

After adding the "Zoom Controls" item to the toolbar, two magnifying glass icons show up, one + and one -. This should probably be explained.

Also, you only need {for fx4} for the new section (not {for fx5, fx4}) since {for fx4} now means "show for Firefox 4 and above".

Thank you, will remember that for future edits.

Just a thought, you might want to add a link to How do I customize the toolbars? for people who want more information about toolbar customization.

Sounds like a good idea to me.

P.S. You also asked, "Are the toolbar items platform specific?". What do you mean? What OS are you using?

I'm running linux, I wouldn't think that it would be different, but it was just a thought that occurred to me in writing the "for" tag.

Re: Font size and zoom - increase the size of web pages

I've now done everything mentioned in my previous post, as well as adding an image. Do the zoom controls look any different in Windows/Mac?

Sorry for not replying sooner.

Here is a screenshot of the toolbar zoom controls in Firefox 5 on Windows 7:

The toolbar zoom controls look the same on the Firefox 5 toolbar on Mac OS 10.6 (no "magnifying glass" icons, just simple - and + buttons). You should make the phrase "magnifying glass icons" for linux (or just remove that phrase) and make the image for linux.

Re: Font size and zoom - increase the size of web pages

Based on bens545's edit, Alice's feedback and the planned updates for this article, I added the Text Zoom section, clarified that it is on a website basis, added a link to the Default FullZoom Level add-on, made the magnifying glass icon specific to Linux, added a Windows toolbar screenshot. It needs review.

I propose also a new article name, "How do I zoom in and out?", different from the mobile article name: "How do I zoom in and out of a website?".
