i have a idea :
if you using OS windows and browser: Firefox, and you didn't clear cache, when load a site, browser created files with extension *.sqlite on this path C:\Users\
(remember, just files this path C:\Users\
this files have very important data , you just install this application => "DB Browser for SQLite.exe" for open this files.
(open "DB Browser for SQLite.exe" => click "open database" => tab "browser data" ======> show your all data, just check all tables)
****** check all *.sqlite , you can search on files this keywords : doge, dogechain, wallet-guid, guid, address,wallet,wallet-id
**** if you did not install new windows or firefox and you used windows and firefox
**** See these images for example :
