Problems with the Firefox extension

Thanks for the link to the link to the 1password classic extension - that will solve my problem short term.

Longer term, looking at your link it looks like I need to find some new software - I've been using 1password since 2008 and bought every version for Mac, iPhone and iPad (remember when those apps were separate purchases?) and even bought a subscription. Moving away from owning and having full control over my own passwords to putting them on someone elses service is a no-go.
