I'm concerned that there is no universal way to prevent this add-on from locally saving sensitive information like social security numbers, phone numbers, etc.. Yes, these sensitive fields can be manually blacklisted for any particular site, but that requires knowing the precise field name; not impossible, but cumbersome to the point of not being helpful.
My thought is that this add-on would be more valuable for some people if it could be limited to fields where the entered test is longer than a specified number of characters. So, a user could say, "Save any field in which I type over 300 characters".
That would side-step local saving of most sensitive data, and focus on saving long text fields that take time to compose.
Any progress on adding this type of option? Thanks!
