Hi Ralf,

I can reproduce the issue as well.
Furthermore, after trying to access the URL provided, and tap on New Tab from Firefox menu, Firefox freezes.

Thanks for your report!

Hi Marcia,

I could not access the URL from Comment 0, but I tried with a similar page https://hdbox.ws/en/news/43-ip-tv-kanaly.html.

Nightly 66.0a1 (2018-12-18) and Beta 65.0b5 did not freeze, but after I started the download, a blank page opened. I have a logcat, if that helps. Tested with Nokia 6 (Android 7.1.1).

Notes: 
This behavior was not reproducible on Firefox Release 64.0.1.
It might be the same issue as in Bug 1500111.

Seems worth investigation since this is happening on more than one site.

Are you able to get a logcat when it crashes? That would be helpful for investigation.

Hi Marcia,

I tried to reproduce the issue, but Nightly does not crash anymore.
Now, after tapping on an m3u file for downloading it, the behavior is:

• Nightly asks me twice to "Complete action using",
• downloads the file twice,
• Nightly opens 2 about:blank pages.

I will attach a logcat and a short video.
Thank you!

It's great that that crash doesn't reproduce anymore.

Regarding https://hdbox.ws/en/news/43-ip-tv-kanaly.html which opens two pages when clicking on the download link, the issue is with the website which executes a second script on the onClick event to provide the same download again.

• the same happens on FF desktop when clicking on the "Download.."
• if pressing to open the link in a new tab only one download option will appear.
• if pressing the "download" image at the beginning and end of the "Download.." text only one download option will appear.

So it doesn't seem like the application has a broken behavior for this particular type of file.

Based on this I'll close this as WORKSFORME.
