r/1Password on Reddit: Where can I download the 1Password Classic Extension for Chrome.-
October 1, 2024 -
I purchased a "Perpetual" license for 1Password 7 just one week before they announced the switch to a subscription-based model. To me, it's frustrating and feels like an unfair business practice. Why sell a perpetual license and then make it nearly impossible for your customers to get the extension for supported browsers and operating systems?
If I choose to continue using "outdated" software and OS, that's my choice, but at the very least, I should be able to access the tools I paid for. I also strongly resist buying into subscription-based software and entering what I see as the "Subscription Exploitation Economy."
I've tried downloading the extension "1Password-4.7.5.90.crx" from multiple sources, only to be hit with the infamous "Error 400." I even found official posts from 1Password staff linking to the file, but the same error persists.
Does anyone know where I can download the classic extension that works for 1Password 7? Any help would be greatly appreciated!

How to download Chrome extension which would work with a standalone 1Password 7 with a lifetime license? Firefox extension works just fine (and it’s what I’m using 98% of the times), but Chrome extension has been giving me headaches…
Just to clarify: I use this standalone for work because we are not allowed to store any company credentials in a cloud. I can never use 1Password 8 for work because there is no standalone version.

I have converted the old standalone extension that works with non-cloud and non-subscription 1Password v7, so that now it uses Manivest v3 and works in Chrome. The link below allows you to see the diff in files between V2 and V3 and load the extension unpacked in the developer mode of Chrome Extensions Manager. Here's the link: https://github.com/MartinMiles/1password-Chrome-Extension-manifest-v3 Now it works again in the latest updated Chrome for me, and works like a charm! Ask: if that solves your problem, please give it a star so that I know it actually helps real people.

It's not possible to download and use the 1Password Classic browser extension within any Chromium browser, and Firefox really only still continues to work as they've yet to make the full transition from Manifest v2 to Manifest v3 -- which is a crucial part of the extension’s structure, as it tells browser how the extension should behave and defines things like what permissions the extension needs, what scripts it will run, and how it interacts with the browser and the web. While we really did our best to keep the 1Password classic extension up-to-date, and we held onto it for as long as we could until its last update in 2019, the deprecation of Manifest V2 in Chromium has forced us to retire it completely. Unfortunately, the technical limitations introduced with Manifest V3 require significant changes that aren’t compatible with the older structure of the classic extension.
