Can't install dictionaries in Zen browser

[sofiasmnk]

Description

• Installed the stable version of Yomitan from https://addons.mozilla.org/en-US/firefox/addon/yomitan/.
• Tried to install dictionaries both from the "Get recommended dictionaries..." option and by downloading the zip files and trying to import them.

After attempting to import a dictionary, if I go to "Configure installed and enabled dictionaries", instead of seeing any dictionaries installed, I get this error message:

NotFoundError: IDBDatabase.transaction: 'dictionaries' is not a known object store name

Browser version
Zen 1.7.6b (Firefox 135.0)

Yomitan version
Yomitan Popup Dictionary 25.1.29.0

I suspect this is some permissions issue. Unless zen browser has ripped out core functionality of indexeddb.

Looked into this and this does not appear to be something that is possible for us to fix.

Indexeddb is specifically set up to where the object stores must be static except for version updates. Yomitan creates the object store schema when the database is first accessed and it cannot be touched afterwards (besides version bumps which we have not done in years). I do not see any issues with this process on Yomitan's end.

If indexeddb gets damaged in some way either by corruption, the browser deciding to wipe out object stores, or some external program deciding to reclaim space (there are reports of system cleaners such as CCleaner doing this), there is nothing Yomitan can do to repair it besides throw out the entire database. Which perhaps Yomitan should do... but for now I'm going to say that we should not.

I'll look into making this error message better and point users to deleting the database themselves. Simply pressing Delete All in the dictionaries dialog will do this.
