Supported Browsers

Textbox.io is based on HTML5 JavaScript and CSS3 standards and will operate on most web browsers that support these standards.

If your application needs to support older browsers, use the textboxio.isSupported() API to verify whether the editor is available at runtime.

Internet Explorer must be in Edge mode

To use Textbox.io on Internet Explorer 11 on a site in the local and intranet Internet Explorer security zones, your page must place the browser into edge mode using the X-UA-Compatible header (see the code fragment below). Otherwise, in these zones Internet Explorer defaults to using compatibility mode (i.e. it reverts to using the Internet Explorer 9 rendering and JavaScript engines). If your application/site is in Internet Explorer's Internet zone then it is not necessary to adjust Internet Explorer's settings.

<meta http-equiv="X-UA-Compatible" content="IE=edge" />

Textbox.io DOES NOT support IE compatibility mode

Importing Images from Microsoft Office

Importing images from Microsoft Office content requires the use of the Adobe Flash plugin on the following supported browsers:

  • Chrome
  • Safari
  • Microsoft Edge

If the Adobe Flash plugin is not available or is blocked in the client browser then textual content will be imported but no image content will be imported.

Copy and paste on Internet Explorer 11 or Firefox (version 45 and above) does not require any additional plugins.

Copy and paste from Microsoft Office is not supported on mobile device platforms.
