Address bar and tool bar text is very small - hard to read. How can I make it bigger ?
I am sorry to hear that you are having this issue.
in order to remedy this, you will need to see the small text once more. Right click a portion of empty space and click customize toolbar (or go into the top right menu => more tools => customize toolbar). There you will be able to click density, then touch to make it larger.
While you are there, maybe play around with your toolbar so that it is how you'd like it!
You can 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 to enlarge or 0.9 to reduce) until icons or text looks right. You might need large value above 1.5 or 2.0 Make sure not to use values too large or too small.
- modifying layout.css.devPixelsPerPx affects user interface and webpages (global zoom)
Firefox has a Zoom section in Settings to set the default zoom level for webpages.
- Settings -> General -> Language and Appearance -> Zoom
You can open the about:config page via the location/address bar. If you get the warning page, you can click the "Accept the Risk and Continue" button.
