Extension 'unlock screen' incorrectly scaled on Firefox

Hi guys,

A recent update to your Firefox browser extension seems to have created a problem for me.

When the browser extension is locked, and I click the 1P button in the browser window, the content of the master password entry screen is too big for the popup:

If I blindly type my master password and press enter, the extension unlocks successfully and from then on appears to be scaled correctly.

I'm not sure what could be causing this issue I'm afraid. (Neither of my monitors is high-DPI)

1Password Version: 8.2.2 (beta channel)
Extension Version: 2.1.2 for Firefox
OS Version: Linux (Fedora 34 on Wayland)

    Hey @ra_ ,

    This usually happens when the 1Password extension icon is hidden in the overflow menu of Firefox, but in your screenshot it seems that the 1Password extension icon is pinned and is always visible in Firefox's toolbar. Is that correct?

    Also, what happens if you disconnect any external monitors or move the browser window from one monitor to the other? Does the issue persists?

    And lastly, if you install the stable version of the extension, does the issue persists? https://addons.mozilla.org/en-GB/firefox/addon/1password-x-password-manager/

  • Hi @ag_yaron,

    Yes, the extension icon is pinned in the toolbar and always visible.

    With two monitors connected, the problem occurs on both monitors. With one monitor connected, the problem still occurs.

    I am already using the stable version of the browser extension (2.1.2). But I am running the beta version of the desktop app (80202072, on BETA channel).

    I have just noticed a new pattern. The first time I click the 1P extension button in a particular browser window, it works correctly. However every subsequent time I click the 1P button in that same browser window, it is mis-sized. If I alt+tab to a different browser window and click the 1P button, it works correctly first time! But then is mis-sized every subsequent time. Switching back to the first browser window it again works correctly the first time, then is mis-sized each subsequent time I open it.

    It seems that, when the 1P extension is first clicked after having been used in a different browser window, and the "Loading..." message is displayed briefly, the problem does not occur.

    It appears the problem is not limited to the master password unlock screen. Once unlocked, if I click the 'settings' cog icon in the top right of the extension popup, the settings panel does not appear. (I assume it is actually opening correctly but 300px or so off-canvas.) The same "works correctly first time per-window" behaviour above also applies in this case.

    Thanks for the additional info, @ra_

    Before I forward this info to the development team, let's perform one last test to make sure this issue is not caused by 3rd party extensions or settings.
    Please try this:

    1. Create a new test user profile in Firefox: https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles
    2. Switch into the new user profile and install only 1Password in it: https://support.1password.com/getting-started-browser/
    3. Test and see if the exact same issue occurs and is reproducible on the new user profile.

    If it does, then I'll investigate this further with the team.
    If it doesn't, then there's something in your main profile that is causing this issue and we can start eliminating things until we find the culprit.
