DashLane extension for FireFox not working properly on Apple Silicon machines

A month ago I purchased a Apple Studio Max 4, I was very happy with the performance. I use FCP and Photoshop and develop on this Mac. So that's a real joy. But there are some things I really don't like. The silicon machines quite obviously have serious sleep issues. Some searching online confirm this behaviour I see on my mac. It is in my opinion by design, references to "sleep" are being renamed, the pulsating sleep light is gone and more things like that. I guess I have to live with that. The same goes for the mediaanalysisd that is constantly "watching my interaction with media" , 8 to 10 hours a day while not sleeping. Already I have been busy for 2 weeks how I can disable the mediaanalysisd without turning of SIP. The answer is you can't, I am no longer in control of my own mac. So I am happy with the performance, but there a very serious issues.

One of them is the DashLane extension in FireFox, my default browser. The last week I have been battling this extension to properly work again. I have done a lot of searching and eventually send this mail to DashLane support. I am sure there are more people using Apple Silicon macs that use FireFox and have 2FA enabled. Maybe you have found the solution I have been now looking for a week. And maybe you want to share it here. Here is the text of the email I have sent to DashLane:

I want to report an unworkable situation with the DashLane extension for FireFox on Apple silicon machines.

For some two weeks, every time I quit FireFox or FireFox is updated I have to reinstall DashLane.

I have done lots of searching on the Internet and found out I am not the only one.

What happens if I restart FF because I have to, I need of course log in to DashLane again. I have 2FA enabled so I have to use an authentication token. But is impossible to enter the code in the window, input is disabled and the styling of the input box is different from the working input fields. The only available option I have is “Use Recovery Key” and even this option doesn’t work.

So every time I must deinstall the extension, quit FF, reinstall and then I can login again. I don’t think this is how I want my user experience to be. As I already mentioned I have done a lot and I mean really a lot investigation about this issue and I can see that for years FF has been plagued with similar issues. To be honest I have never had any issues and was (yes, was) quite happy with DashLane until I got my new silicon mac.

I did a clean install which of course took it’s time to be able to rule out any corruption of my old machine.

What did I do to troubleshoot?

I uninstalled all extensions and only left DashLane, that did not work.

I removed my device from synced devices via the Mozilla site , exported my bookmarks in json format.

Deleted my Profles folder in ~/Application Support, downloaded and installed a fresh FF.

From my iPad I logged into DashLane, went to Settings, Activity and deleted my Apple Studio desktop machine.

Installed the DashLane extension as first and only extension and I am back into the same ****.

My problem could maybe resolved by turning of 2FA, but I can’t and and don’t want to do that. I have lots of passwords from customers who trust me with their passwords. I want be as safe as I can and having my passwords online is already quite on issue for me. And if accessing my data is made almost impossible than I might have to seriously look for an alternative.

These problems don’t present itself on Safari and Brave (Chromium), so it really looks like DashLane is not willing to fix the extension, or not being able to make the extension work on FF on Apple Silicon. Both options don’t make me really happy.

All my other extensions work flawless, but the most important one, my password manager, does barely work. Because for me removing and reinstalling every time is totally unacceptable as a solution. How can I trust my password manager that can’t even develop a working extension for my browser? I am a webdeveloper, I have about 600 passwords stored, it is impossible to work like this. I want to keep using FF, I have my reasons to do so. Please tell me if you have abandoned FF, then I can move on with another password manager that is able to develop a working extension for FF.

And don’t tell me you haven’t heard of this bug, I will attach a screenshot from a search in Google: "bug dashlane firefox macos apple slicon”,

Please read the attached FIRST AI answer from Google.

The bug I encounter is not on the iOS platform.
