Add-on pop-ups without clicking download

[bdcomp]

The just released WE version of this great add-on opens several pop-ups without clicking download or any other interaction from me.
It looks like some ads related urls.

Open in Browser 2.0
Firefox 57
Kubuntu 17.10 64bit

This is because the server does not send a type. Normally Firefox will sniff the type and then either display the content inline, or download it. To not have those dialogs, select the top option ("Open with Firefox (Choose other application") and then it is up to Firefox how to view/open it. You can choose to remember the choice to always do this in the future (and if you want otherwise reset the preference at the Preferences page). This issue can be fixed automatically if #5 is implemented.

Thanks for the prompt reply.
This workaround works, so far.

Although, #5 will great improve the out-of-the-box behavior.

Just wondering, isn't it possible (without #5) to preset this workaround on add-on installation?

The issue is that without a MIME type, the extension does not know whether a dialog should be shown.
For your specific case I have found another work-around, which I will push with the next update.

I published 2.1 with the above fixes. Please try again without the preference and see if you still encounter unwanted dialogs while browsing.

The 2.1 version improved a lot the out-of-the-box experience - only 1 pop-up after hours of browsing.
It's similar to the description's screenshot, just (1 kb) in the "which is" line.

Great work!

Do you recall the circumstances under which that had happened? If you do then I can investigate it and try and fine-tune the checks even more.
