Open Bug 1396396 Opened 3 years ago Updated 2 years ago
Page is not refreshed after form submission
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 ?  https://blog.nightly.mozilla.org/2017/06/07/using-mozregression-on-windows/
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 See https://github.com/gorhill/uBlock/issues/2982#issuecomment-327463631

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.
