Text Size Adjuster by Narve Sætre

Text too small on a website, and zooming in makes you scroll sideways to read each line?
Don't want to use your reading glasses right now?
Text Size Adjuster makes just the text bigger or smaller.
The page still fits your screen, and pictures and layout keep their size.

• Zoom in on a page (pinch, or Ctrl/Cmd and +) and a small control appears: tap + or − to resize the text.
• Or use the Text Size Adjuster button in the toolbar at any time.
• Headings stay bigger than body text — everything scales together.
• Your chosen size is remembered for each website and applied automatically next time.
• Choose which corner the control sits in, and whether to always show it.
• Works in Firefox on your computer and on Android.

No tracking and no data collection: your settings stay in your browser.

NOTE: It is not perfect. On some pages, some text may not resize, or may be cut off inside small fixed-size boxes.
