I have posted regarding this issue before, but nothing solved the issue. I have new information and I'm curious if it helps. Every few months I lose every saved password in Firefox. I open it up one day and the saved password section is blank, 50 passwords just evaporated. I have done a little more research and per other support tickets I found a folder containing the logins.json files. I assume this has to do with saved logins? What's peculiar is that there are multiple corrupt files, (see attached image). Is this what is causing my saved logins to evaporate from Firefox? What can be done about this?

Is the file really corrupt (i.e. contains non ASCII binary data)?

We have recently seen cases reported about AVG software that prevents Firefox from accessing logins.json with the result that Firefox renames the file and add .corrupt (logins.json.corrupt) and starts with a new file.

See:

Mozilla has created an extension to recover logins.json from a possibly numbered logins.json-##.corrupt file.

Your solution was 10/10 successful. I do use AVG. I updated, installed the add on, I restored the file, all my passwords have returned. Very impressive, thank you for your time in helping me resolve my issue!
