I made an xml search addon.
How I can reproduce the problem:
- On the ‘2. Upload your add-on’ page I choose my addon file.
- ‘Your add-on was validated with no errors or warnings.’ appears.
- I press the Continue button.
The page then loads indefinitely and then stops, showing an empty page after a few minutes. One time it said ‘500 Internal Server Error’.
Browser: Firefox, latest at the time of writing (44.0).
