Build ID: 20170125094131

Steps to reproduce:

As soon as I open the dialog box to select a file for uploading, the browser crashes. Though, when I drag and drop the selected files, it works.

Actual results:

The browser crashes.

Expected results:

The files should be uploaded and the browser shouldn't crash.
do you see Crash Reporter [1] when it happens?
if so, can you send the Crash Report and provide the Crash Report ID shown in about:crashes page?

Yes here is the report: https://crash-stats.mozilla.com/report/index/1b652dd9-44dc-41ce-8c98-419412170301

and the crash ID: bp-1b652dd9-44dc-41ce-8c98-419412170301
it's a crash inside flash.
maybe a dupe of bug 774281

If you have precise steps to reproduce this crash, it's not a duplicate: that bug only tracks F139... crashes that we don't know how to reproduce.

petitelouise, could you try to write down precise steps to reproduce this bug? In particular:

The exact URL you are visiting.
The precise key strokes or mouse clicks you use to reproduce the problem.
The contents of your about:support data and anything else "unusual" about your computer or setup that might make it easier for somebody else to repeat the same crash you're seeing.

Hey, so I deleted the flashplayer.exe I had in my downloads folder and it's not crashing anymore! Thanks for the inputs :)

Hey, so it was working fine and it's doing the same again...
@Benjamin Smedberg I don't use a URL in particular because the bug happens when I try to upload files through my email, through Facebook or like this transcription website for example: https://transcribe.wreally.com/app#
So I click "browse", the window opens to browse in my computer's files and then the whole browser closes within 3 secs.

here the data of my about:support. The only thing I can think of is that I downloaded a new plug-in yesterday (AdBockPlus)...
