How can I make the text and buttons bigger?

I was wondering if there was some way to make the text (including text of toolbar options and tabs), buttons, toolbar menu, everything about the browser bigger. Everything is extremely small & I'd like it as bigger as it was on the laptop I was using before (which isn't a Mac). I hope you understand what I'm asking. Thanks.

I found out how to fix the size in the "system preferences" for the computer.

Hi cje24576, I suppose it depends on how much bigger. The Mac itself may have options to change screen resolution for instance, but I do not use Macs myself.

The no squint addon may help.

Need very big button etc. look at the accessibility solutions on

Note that you can do this in Firefox via the layout.css.devPixelsPerPx pref or with the global setting in Theme Font & Size Changer that modifies this pref as well.

Set layout.css.devPixelsPerPx to 1.0 (default is -1) on the about:config page. Adjust its value in 0.1 or 0.05 steps (1.1 or 0.9) until icons or text looks right. Modifying layout.css.devPixelsPerPx affects user interface and web pages (global zoom). You can use an extension to correct the appearance of web pages.

You can look at the Default FullZoom Level or NoSquint extension to set a default font size and page zoom on web pages.

Thanks, but as you can see in my earlier post, I've already found a solution that isn't another add-on.

If you modify the layout.css.devPixelsPerPx pref on the about:config page directly then you do not need an extension, but if you can do this via the Mac OS then that is fine.
