I made some slight changes to make the page work under GeckoViewExample.

Under GeckoViewExample , the image could be viewed after pushState.

From the document of createObjectURL

>The URL lifetime is tied to the document in the window on which it was created.

So i guess in Firefox for Android, pushState might cause the document changing?

Ok , i might find the problem....

Here , when location changed, the upload cache would be cleaned
