1517531 - Handle IndexDB pref failures gracefully

Status: NEW

(DevTools :: Debugger, enhancement, P3)

Description

[Logan Smyth [:loganfsmyth]]

We converted our preferences to be stored in IndexDB in some cases, and have since heard a few issues in https://bugzilla.mozilla.org/show_bug.cgi?id=1512796 and https://bugzilla.mozilla.org/show_bug.cgi?id=1503883 where IndexDB appears to be having issues.

We should handle IndexDB errors in a more graceful way by letting the user know an error happened. Ideally we should also add more output in the log so that we can get a better sense of what specifically is failing, so that we can try to add more logic to recover from errors in the long run.

FYI, there is a link [1] to check if the storage of users' profiles can be initialized or not. (if not, then it means their IndexedDB cannot be accessed).

Meta bug for tracking the initialization issues: bug 1482662
The bug for providing more useful information on IndexedDB: bug 1502077

STR:

1. Go to about:config and set dom.indexedDB.enabled to false
2. Restart browser
3. visit any site and open devtools, debugger is blank ( nothing is shown )

Can I work on this issue ?

@dhyey35 If you'd like to you can certainly give it a show. I don't know off the top of my head what we'd want to do, so I'd recommend raising the issue in Slack if you do start working on it.
