All custom filters disappeared

[IgitBuh]

Describe the issue

Suddenly all my custom filters are gone. The tab "My Filters" is now empty. I've been using uBlock Origin for about one year now and I've been adding custom filters piece by piece whenever I noticed something annoying on a website. Now all this work is gone.

Steps for anyone to reproduce the issue

Well, I don't know the reason or the exact moment they disappeared. Maybe it was with an update (I'm now at uBlock Origin v1.14.4), maybe after a Firefox crash. I probably didn't notice it right away, because the changes are subtle and not on all websites I frequently use. I definitely didn't enter any new custom filter in the last weeks, so it can't be due to a new filter.

Your settings

• OS/version: Windows 7, x64
• Browser/version: Firefox ESR 52.3.0 x86
• uBlock Origin version: v1.14.4

Id didn't find any topic with the same problem, so I decided to describe the problem I encountered.
At the same time I'd like to ask for help, in case there's something I could try to get my filters back. In which file are the custom filters stored? I could try to analyze that file or to see if I can get it back from a system backup.

@IgitBuh: Poorly searched then:

1. A duplicate of [Firefox] Settings Completely Wiped. #2960
2. Also the same can be found at:

   then scroll to the bottom >> Version information>> see release notes

It's all explained in the release notes and the front page of uBO on AMO.
