noVNC should work on any browser with reasonable HTML5 support.
|
||||
In general this means:
|
||||
noVNC should work on any modern browser with reasonable HTML5 support. Due to the fact that browser platforms are constantly updated and changed it is difficult to maintain a list of supported browsers the core noVNC team mainly test the newest versions of browsers. But the we *know* that versions older than the following **will not work**:
|
||||
|
||||
- Chrome 8
|
||||
- Firefox 4
|
||||
- Safari 6
|
||||
- iOS Safari 5.1
|
||||
- Opera 12
|
||||
- iOS Safari 10
|
||||
- Opera 12.1
|
||||
- IE 11
|
||||
- Edge 12
|
||||
|
||||
The major limiting factors are the HTML5 features Canvas, WebSockets
|
||||
and Typed Arrays.
|
||||
|
||||
The older v0.1 release of noVNC has some support for older browsers
|
||||
The old v0.1 release of noVNC has some support for older browsers
|
||||
(e.g. Firefox 3.0, Chrome 4-7, Opera 10). Testing results for v0.1
|
||||
can be found at [[Browser Support v0.1|Browser-support-0.1]].
|
||||
|
||||
The following tables show results of testing the current version of
|
||||
noVNC on various browser and OS combinations.

* Note 1: Firefox 4/5 native WebSockets support can be enabled by
|
||||
navigating to URL `about:config` and enabling option
|
||||
`network.websocket.override-security-block`. Opera 11 native
|
||||
WebSockets support can be enabled by browsing to URL
|
||||
`opera:config#UserPrefs|EnableWebSockets` and enabling the option.
|
||||
|
||||
* Note 2: Firefox does not provide a direct way to accept
|
||||
SSL certificates via WebSockets. You can work around this by
|
||||
navigating directly to the WebSockets port using 'https://' and
|
||||
accepting the certificate. Then return to noVNC and connect
|
||||
normally.
|
||||
|
||||
* Note 3: Firefox 6 is abnormally slow running on Windows 7. I believe
|
||||
this is a bug.
