Hello shahin_touhid,

For doing Zoom in, that is for making text bigger in size simply press and hold 'CTRL' + '+'. That is press and hold CTRL key and then press + sign key to zoom in text according to your need.

For Zoom out that is to make text size smaller Press and hold CTRL Key and then press - sign key. That is 'CTRL' + '-'.

You can also do the same using View menu from toolbar.

Simply press CTRL+0 for normal view.

Please reply back if you find this helpful. Thank you..

That is a Desktop answer for a support request for Firefox for Android.

In the Android OS settings there is a display option for text size.

• Open the Android settings
• Select Display
• Select 'Font size'

The exact name and location of this setting will depend on your specific phone or tablet.
