User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:52.0) Gecko/20100101 Firefox/52.0
Build ID: 20170802111520

Steps to reproduce:

1. Open the form at http://sagamusix.untergrund.net/fileupload-2.htm
2. Select a small file for upload and submit it


Actual results:

Firefox 52 ESR and Firefox 55 upload the file to the server as expected, but they never show the resulting page. This HTML snippet is extracted from a server application and I was able to verify that the resulting page is being served to the browser, but it was never displayed there.


Expected results:

Like in Firefox 54, the resulting page (Saying "Done!") should be shown.

Note that this might be closely related to bug #1396395 which I submitted.

Hi Johannes, thanks for reporting this. Would it be possible that you get a regression window for us according to [1]?

After closer inspection, it seems like uBlock Origin needs to be installed to trigger this bug. Possibly an add-on issue, but the related crash in bug #1396395 indicates that Firefox might be doing something wrong here as well.

After further observation, the behaviour occurs only if uBlock Origin and either one of the following legacy add-ons is installed:
* BetterStop 1.0.1
* Image Zoom (ugly fixes) 0.0.1
* Web Developer 1.2.13

baku, do you have any thoughts here? I'm not sure what we can do given the add-ons trigger this ...

This bug cannot be reproduced with FF57 because the legacy addons cannot be installed.
I would like to wait what ublock developers say about this bug.

Giving the findings in bug #1396395 (which is now public), it sounds to me like fixing that bug properly could also resolve this bug here.
Given this reproduces only if certain legacy add-on installed, moving this into P3 backlog.
