How to make default zoom e.g.125% without add-ons?

Very simple issue. Every time I open new page I need to press two times Ctrl++ , to make zoom proper for me.

There are add-ons for this, however noSquint distorts some pages (which ctrl++ doesn't), and "Default fullzoom level says it's depracated and works poorly with firefox >=29

I use fresh installation of firefox 30 on Ubuntu, only default ubuntu add-ons.

browser.zoom.siteSpecific set to false doesn't solve the issue, neither manipulating with: zoom.minPercent;30 toolkit.zoomManager.zoomValues;.3,.5,.67,.8,.9,1,1.1,1.2,1.33,1.5,1.7,2,2.4,3

Is there possiblity to press Ctrl++ 2 times and make firefox obeying this for all pages?

Best regard Krzysiek Pluciński

  1. Go to about:config page.
  2. Search for browser.zoom.siteSpecific change its value to false
  3. Set the zoom.

Unfortunately It won't work. Here is excerpt from True Remember the zoom level on a per-site basis. (Default)

False The zoom level should be applied on the current tab only.

Setting it to false will make things even worse, as zoom setting will have to be reapplied to any site, even previously visited (and previously zoomed) :/

Did you check the NoSquint settings to make sure that full page zoom is used and not zoom text only?

Disabling text zoom only to use full page zoom should work with most pages, although there still might be issues with pages that have JavaScript that modifies pages according to zoom changes that they detect.

Note that you can modify the toolkit.zoomManager.zoomValues pref, so it has your preferred zoom value as the first zoom factor after the default 1 zoom factor (<...>,1,1.xx,<....>). You can also drag the page zoom buttons out of the "3-bar" Firefox menu button drop-down list on the Navigation Toolbar via Customize and click those.

The main problem is that Cyber Security compliance forbids me to install most firefox plugins.

Changing toolkit.zoomManager.zoomValues is partially helpful, by reducing for example 2 Ctrl++ clicks to one (as we always start with factor=1 and then next Ctrl++ hit moves to min value from this zoomValues list, which is our desired factor), but still each time for new page we must press shortcut again to switch to proper value...

What is missing is simple value like "DefaultZoomFactor=1.25", meaning that any new site starts with this factor.

I suppose that without plugins it's not possible to solve the issue with current implementation. I hope it will be changed some day ;) Thank you for your help!

Hi, I found this thread because I had been wondering if there's a simple way that FF could automatically display text bold ...even upon CONTROL + opposed to CONTROL ++++

Note that I require ++++ for it to be easily readable for me.

But if it were bold then ++ might suffice.

But firefoxjelly's knowledge is way beyond mine - if only there were a way people could set the default to their comfort level.

My suggestion: Setting Comfort-TextSize Default should be made as easy as setting the home page to the URL of one's choosing, IE:

Tools, Options, General

Hi firefoxjelly, without an add-on, the closest setting is one that zooms both the content AND the toolbar area. You can think of it as a global zoom factor.

You can adjust the value, but it might be hard to find just the right number:

(1) In a new tab, type or paste about:config in the address bar and press Enter. Click the button promising to be careful.

(2) In the filter box, type or paste pix and pause while the list is filtered

(3) Double-click the layout.css.devPixelsPerPx preference and change its value as desired:

  • -1 uses your operating system zoom level (this is the default value)
  • 1.0 uses the classic 96dpi font size, which may look too small on modern, higher pixel density displays
  • try 1.2 or higher to enlarge text

You may need to switch back and forth to other windows/tabs to see how it's affecting them.

Warning: do not use a very tiny number, as you will have difficulty seeing anything.

Hi Minni, there isn't a built-in setting to force all fonts in a page to use their bold variant. You might be able to find an add-on to do that.

jscher, I'd rather just have my above suggestion made available in Tools/Options, nearby the homepage-default.

That's most intuitive.

What's the easiest & safest way to Uninstall NO-SQUINT? And why is it so hard to locate it, such as when I wanted to lower the default-zoom which I'd set??

I'm desperate. I've now found NO-SQUINT to be incompatible with YahooMail-Classic, so I'm desperate to Uninstall it. For example, it caused my DELETE-MAIL button to disappear. Note that Classic only functions upon my Disabling JavaScript, so that could factor in to the forementioned incompatibility.

P.S. FYI the New-Yahoomail is so horrible, that I feel crippled without Classic. Not that its the original-classic (the butchered version of Classic sucks as well, but not as bad as the new-tyrannical version.

Hi Minni, I use Zoom all the time...

You can use the Add-ons page to disable or remove an extension. I think you are on Windows, so you can use either:

  • Ctrl+Shift+a
  • "3-bar" menu button (or Tools menu) > Add-ons

In the left column, click Extensions. Then scroll down the list until you find NoSquint.

Edit: Or you can use the method in the reply to your new question, which I hadn't checked before posting this. Safest way to Uninstall No-Squint - so previous settings restored?

Note that you can use code in the userContent.css file to set bold font for web pages and possibly also specify a specific font family.

Add code to the userContent.css file or use the Stylish extension.

* { font-weight: bold !important; }

You can experiment how it looks without the !important flag

The customization files userChrome.css (user interface) and userContent.css (websites) are located in the chrome folder in the Firefox profile folder.

You can use this button to go to the currently used Firefox profile folder:

  • Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)
  • Create the chrome folder (lowercase) in the <xxxxxxxx>.default profile folder if this folder doesn't exist
  • Use a plain text editor like Notepad to create a (new) userContent.css file in the chrome folder (file name is case sensitive)
  • Paste the code in the userContent.css file in the editor window
  • Make sure that you select "All files" and not "Text files" when you save the file via "Save file as" in the text editor as userContent.css.
    Otherwise Windows may add a hidden .txt file extension and you end up with a not working userContent.css.txt file

Well for one thing, I wouldn't know where to type in this:


Aside from that - I never did master CSS.

So as tempting as it is to have the bold etc. I think I'll pass.

Hi Minni, are you running Windows?

%APPDATA% is a shortcut for C:\Users\username\AppData\Roaming

You can type or paste it wherever you would enter that longer path to get to that folder, such as the address bar of a Windows Explorer window, or the search box on the Start menu (Vista-7), or the Run dialog (XP, Windows 8+).

Uh, jscher, I wish I could remember my username, since I've always just simply logged onto computer via DSL modem.

I.E. Turn on my system, click on the FF icon, & set to go.

Aside from that, even if I'd remember my username (scratching my head trying to remember the murky past)... ...I'd still need complete instructions, itemized.

I.E. (1) key in: blah blah ENTER (2) KEY IN: blah blah ENTER

Please understand, my head is in a zillion directions these days (very busy & can't cope due to being on my own) so please understand if/when I don't always respond promptly, or overlook responses! And thanks for all your help.

Tangentially, btw, I've read major predictions of major world changes as of the end of this month, so this all is probly moot anyway!

Hi Minni, honestly I've lost track of where this is all going now.

But I'm pretty sure you can figure out your Windows user name. If you open a Windows Explorer window and look at your C drive and then the C:\Users folder, there won't be a whole lot of folders there, and one of them is the one you're currently using.

more options

Hi, I did not see "users" listed under C: (nor under c:\windows for that matter.

Tangentially speaking - today when I tried printing one of my HTML files via FF, the display wasn't nice until I opened it with Explorer. It was a series of 4 bumper stickers which i'd painted in each one below the next, filling up an 8x11 sheet in portrait (not landscape).

Somehow, even though the dimensions were 11"x3" for each sticker, yet on its own, Explorer aligned them nicely - squishing the 11" width into the 8.5" portrait-width. Furthemore, I was also instantly enabled to remove headers/footers.

Whereas in FF, I could not do the latter instantly. Nor did the sitckers align as nicely as Explorer. I had tried 100%, 90%, 80% etc.

So yes, there's room for FF to improve some of its capabilities.

I know this is a tangent, but not urgent to me, since IE bridged the gap. I just posted it in case anyone interested wants to pass it on.

Hi Minni, if you do not have


then you probably still have Windows XP. Look under:

C:\Documents and Settings


Is your HTML document online somewhere? It's hard to comment on why Shrink-to-fit didn't work as designed without being able to see it.

more options's what I found:

c:/docs and settings/all users

the latter folder contained these folders: desktop favorites shared docs start menu

But now I lost track of what you had in mind.

Look, don't worry about it, OK? The world is changing too fast for me to handle tech problems anymore.

Thanks for all your efforts helping everyone.

As for shrink-to-fit, it happens often, that I resort to I.E. instead of FF to print, since the layout is closer to what I seek, rather than "awkward". Maybe its different with your system, so that's why we're on different pages (forgive pun)
