Short-term solution: Ignoring those download requests.

Long-term: Saving the data behind the blob URL as Download.

• GeckoView: https://bugzilla.mozilla.org/show_bug.cgi?id=1501735
• WebView: Ouch! Maybe just ignore them in WebView: https://stackoverflow.com/questions/48892390/download-blob-file-from-website-inside-android-webviewclient/48954970#48954970

Steps to reproduce:

1. Open https://squoosh.app/
2. Select one of the predefined images, such as the large fox photo.
3. Tap the blue download button.

Still reproducing on Nightly 11/13. Thanks!

I was also able to reproduce this from the STR in this comment if ever need more links to try: https://github.com/mozilla-mobile/fenix/issues/2579#issuecomment-535981773

Could this issue be revived ? It is preventing the download of COVID19 attestation from the french government website.

@lovasoa do not worry @kglazko is taking a look at it!

For comparison, in Fennec F-Droid it doesn't work either, but the reason is different - clicking the button to generate the attestion doesn't even attempt a download.

Cheers 🙂

Note that as a comparison, it works on old Firefox for Android beta, but I fear when this beta will be upgraded to Fenix any time soon!! Thanks for taking care of it in these dire times. :)

Downgrading this to a P2 for now so that not everything we send to GV is P1 - we should bump this later if we reprioritize on the Fenix side.

[kbrosnan]

This is one of the more common download issues users encounter. There is a fairly good list of dupes here, on Fenix, and Webcompat.

Hi all,
I checked Fennec F-Droid again and it downloads the attestation form fine, I don't know what I was doing wrong before.
Cheers 🙂

Still doesn't work. Tested on: https://media.interieur.gouv.fr/deplacement-covid-19/

Version: 5.0.0 (Build #21212136) 39.0.1, f19856fa4 GV: 76.0-20200424000239 AS: 0.58.2

Also affecting mega downloads https://www.reddit.com/r/firefox/comments/gi3s23/cant_download_files_from_mega/

We can download blobs 🎊🎉 (tested with telegram web and squoosh.app)

Awesome :)
We still have some issues with Firefox Send and some extensions that use blobs, but most of the sites should work now. We need help to test multiple sites and discover possible edge cases, if you see something that is not working please, let us know :)

[madb1lly]

Hi all,
Confirmed working for https://media.interieur.gouv.fr/deplacement-covid-19/
Cheers 😃

[Amejia481]

I tested with the latest geckoview version 78.0.20200521093657 and the FireFox send issue is gone 🎉 . For this be on Fenix we need a new version of ac that includes the above GV version. We can close issue and follow the https://github.com/mozilla-mobile/fenix/issues/3336#issue-454639904 ticket to confirm with QA

[1M6host]

please if anyone is facing this issue.. the following worked for me :-

go to "\node_modules\react-native-webview\android\src\main\java\com\reactnativecommunity\webview" in your android studio and then method "webView.setDownloadListener()"

    DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url.replace("blob:","")));

replace this line

rebuild and run the app normally
