2. click the top-right button "下载" on the web page。
3. close the download dialog and the blank tab, then click the “下载” button again

Current Behavior

1. After the first click，the download dialog can show，but after the second click，the dialog cannot show expectedly
2. After the first click, onNewSession, onPageStart, onExternalResponse, and onPageStop are called. But after the second click, only onNewSession and onPageStart are called, no onExternalResponse and onPageStop. As a result the new blank tab is always loading.

I can reproduce it indeed, I thought it might be an issue of kiosk mode but it fails in "normal" mode.

We'll check that, thanks for reporting!

The issue is still reproducible in 1.4.2

Really interesting bug. I was doubting this to be a gecko-related issue because of the missing events, but I can't reproduce it on Firefox Android, so it's not. So I highly suspect it might be something related to cache.

Confirmed that it's something related to cache!
