I'm looking to import my uBlock Origin settings from my desktop PC, which is in a text file, to uBlock Origin in Firefox for Android.

The issue is: When I click on the 'Restore from file...' button on uBlock Origin in Firefox Android, I only get prompted to choose between camera / image apps:

In a Windows PC, clicking on that button will open up an Explorer window allowing you to select a text file to import. I can't import a text file with any of the above apps shown. Is there an app I should install to allow this? How should I configure it?

Details: I have Google Drive and ES File Explorer installed. This is on Android 4.4.2, Firefox for Android 44.0, uBlock Origin 1.5.5.

  • Not sure if this help, but do you have Google Drive installed? Otherwise, I suspect this is a bug on uBlock Origin: it seems the file type (or MIME type) is set to image/* for unknown reason.

  • @AndrewT. Yes, I also have Google Drive installed. Commented Feb 10, 2016 at 9:22
  • @AndrewT. The file type is set to text/plain, see source code. I need to investigate why this happens.

  • @beeshyams Could you add that as an answer so I could accept it? That made it work for me. After I installed App Picker Classic, I could then select it as the file upload app and then choose another app that could upload the file. Commented Feb 10, 2016 at 14:48

As confirmed by OP this app resolved the problem App Picker Classic. From app description

If you have app choices that are currently hidden - maybe you chose "Always" by accident once, but you'd like to be able to reinstate the app and choose each time - then reset these by clearing the defaults in the application manager of your phone/tablet.

In addition, this app permits working with some app intents and resolves common URLs. One needs to install the app, reset defaults and enable required app.


Despite the app being not updated for last two years, it even works with Marshmallow, as can be seen from @Arlinds answer here - which was a surprise to me, and the reason for remembering it !

    I'd like to add here that in my case, I didn't even have to clear the defaults through App Picker Classic. I just had to install it and then it was shown as a choice in the file upload app. Commented Feb 11, 2016 at 5:36
