[Affected platforms]: Windows 10 x64 Windows 10 x32 Windows 8.1 x64 Ubuntu 14.04 LTS Mac OS X 10.10.5 [Steps to reproduce]: 1. Launch Firefox 2. Download a large file (ex: https://www.ubuntu.com/download/desktop/thank-you?country=RO&version=16.04.1&architecture=amd64). 3. Click Download Panel. 4. Right click on downloaded item and toggle between Pause and Resume multiple times. [Expected result]: The download resumes without any issues. [Actual result]: The download fails. [Additional notes]: a. This issue is reproducible 20%. b. Screen cast with the issue: https://dl.dropboxusercontent.com/u/109148197/Download%20panel/Download%20failed.mov . c. This is reproducible also by canceling and retrying a download.
Hi Drew, Paolo, I think we uplifted a few fixes in this area during Aurora50 cycle. Could you please investigate? I am not planning to block 50.0b9 build on this issue as I don't believe this is a recent regression since 50.0b8.
Hi Ritu, this doesn't look related to the downloads blocking bugs I worked on, and I'm not working on the downloads panel right now but I think Paolo is, so I'll let him answer.
Thanks Drew! Hi Panos, this is a regression that was found by Softvision during 50.0b9 sign off. Could you please help find an owner who can quickly investigate and root cause? We are a week away from entering RC mode for 50. I would like help to better understand how severe this issue is and what would the risk of a fix be.
Cristian, do you think you could find a regression range?
Hi Ritu, Paolo is the best person to figure this one out, as he recently reviewed significant code changes in the downloads panel from the Taipei team. So if this is a recent regression, it is likely caused by one of those patches. I agree that this shouldn't block 50.0b9 and possibly even shipping 50, as it sounds like a rare event with an uncommon set of user actions to trigger it.
It's unlikely this is a recent regression, unless there were changes in the network layer.
I am unable to continue in investigating the regression range due to bug 1312706, the pause button now becomes inactive after the user pauses and resumes the download once.
I've looked at bug 1312706 too, and I don't think they are regressions in Firefox. I have not been able to reproduce the issues described in these bugs, and I'm not aware of any code changes in the area. This is more likely a server issue, or maybe, since the actual downloads from the Ubuntu mirrors occur over HTTP, you may be behind a company firewall or proxy that interferes with the connection.
