Thanks for reporting this @nikoloskid could you provide steps to reproduce? Are you downloading from a authenticated site (requiring login)?

[vesta0]

@sv-ohorvath please let us know if you can re-produce this.

[sv-ohorvath]

I've downloaded 2 types: .conf and .config files from an email, no problems downloading from there.
devices: Huawei P20 lite (Android 9), Galaxy S8 (Android 9).
@nikoloskid If you're still experiencing this problem, please give us more details and reopen the bug. Thank you!

This problem still happens on the latest Fenix from Playstore (build #12700628), here's how you can reproduce it:

• open Fenix, paste this link to a .cia file that's hosted on Mega: https://mega.nz/#!KVg0DSaa!Ub2Mcq45UJF_LOG0PtGum3sQpeWhlm4eTmZSMEs9fDM

• download the file, you'll get the following error (same as OP): https://imgur.com/a/YJP3p8x

EDIT: I'm running more tests, and it seems to be a problem that only happens with Fenix + Mega:

• downloading the same .cia file from google will work fine, you can test it from here: https://drive.google.com/file/d/1sC85X65g0B08JH05gzFgIsg-c6TqjbDK/view?usp=sharing

• downloading a .zip file from Mega will give you the same error as the .cia file, you can try it from here: https://mega.nz/#!7FhkwaCR!md-sIMoDCmXB33EU20_2tS5T6vRP7KW6gzkEoA1cOUw

Oh, all downloads that aren't working on Fenix will work fine on Chrome mobile and on Firefox for Linux.

I encountered this bug when trying to download a .conf file from Mullvad. It was my generated wireguard config.

This is also happening for files on Mega, as reported at https://webcompat.com/issues/41768

This link can be saved fine in Fennec, but Fenix rejects it: https://mega.nz/#!j7x0wQDR!j7YAxYNDxILDgpdpZaQrEIC_SphjObeyaG54BU4J-V8

QA can you verify this is still happening?

QA can you verify this is still happening?

Yes, still happens.

EDIT: my latest update from playstore is from 10/30/2019, I guess there's a new release I didn't got yet?

@evertonstz I believe this is fixed in our nightly & beta build :)

Still reproducing on Nightly 191113. Can't download the files evertonstz and wisniewskit shared here.

Verified as fixed on the latest Nightly build 5/21, checked most of the linked closed bugs (where the specific link was still available).

This also happens when trying to download a bin file from a ftp server.
Build# 2015762833
Try downloading either file from this directory: ftp://ftp.dd-wrt.com/betas/2020/09-10-2020-r44340/tplink_archer-c7-v4/

This issue was about a specific method of providing downloads using theblob: protocol and has been resolved.

If you are seeing download issues please test the nightly build if it is still broken in the nightly build open a new issue.
