Error in local storage - NS_ERROR_FILE_CORRUPTED - firefox

Question

I\'ve been working in a web application and I\'m using local storage. But for some Firefox users I notice that they\'re having the following error:

NS

Answer 1

Clearing everything via the Firefox preferences may not fully clear the local storage where the corrupted SQLite file resides.

At this point, you have two options:

• Pop open your console and clear the storage via a Javascript command (hat tip: https://davidjb.com/blog/2017/11/resolving-an-ns_error_file_corrupted-error-in-mozilla-firefox/):

localStorage.clear()
sessionStorage.clear()

• Use the terminal to delete the corrupted SQLite file and force Firefox to rebuild it.

Steps for macOS users:

1. cd /Users/myusername/Library/Application Support/Firefox/Profiles/.....default/
2. rm webappsstore.sqlite

3. Verify no other files corrupted using this script from TheConstructor:

   for i in $(find . -name '*.sqlite'); do echo "$i"; echo "PRAGMA integrity_check;" | sqlite3 -bail "$i"; done

4. Restart Firefox and reload the page.
