1668182 - open file dialog doesn't save preferences

Status: RESOLVED DUPLICATE of bug 453455

(Firefox :: Untriaged, defect)

Description

[u671177]

Attachment: 2020-09-29 08_20_25-Icinga_ monitoring.rantzau.de and 3 more pages - Work - Micros - __Remote.png

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:81.0) Gecko/20100101 Firefox/81.0

Steps to reproduce:

I have a question regarding the behaviour when opening a .pdf file from web email. We are using FF 68.11.0esr on a terminal server environment and we customize it via config file.

When opening a .pdf or even office docs, Firefox asks what to do with this file. When selected open with Adobe Reader and check mark that it should do this from now on with all pdf files it doesn't do that.

Actual results:

The next time when I try to open a .pdf the same dialog window appears again but it remembered the check mark.

Expected results:

But it should open the file directly in Adobe Reader without showing the dialog window. I tried to do it in "safe mode" and even "refreshed" Firefox but no improvement.

I asked the Firefox Support Community and they suggested to open a bug here because it seems like it might be one but not sure. Thanks in advance

Do you think this is the mime type problem again?

I don't understand what this is referring to. I suspect this is bug 453455.

Reporter: what is the value of the Content-Disposition header for these files (you can find out by selecting the network request for the pdf files in devtools' network panel, and inspecting the response headers in the right-hand pane).

Hey Daniel,
Does this issue still occur? Could you check what Gijs suggested ?

Good morning Andrei,

Yes, the issue still exists. I just didn't have the time yet to check the value of the Content-Disposition like it was asked. I hope I will find some time this upcoming weekend. I will keep you posted.

Dear Gijs,

Is this the information you were asking for. See new attachment

Almost - if you click the entry (that you're hovering over in the screenshot) in the network panel, a pane should show up on the right-hand side that shows the request and response headers. We need the response headers from that.

Thanks very much for the screenshots!

Yes, unfortunately this is a result of bug 453455, for which we do not at this time have a straightforward solution. :-(
