1PasswordX Chrome Extension is always 'corrupted' now...

Multiple times daily, the 1PasswordX Chrome Extension becomes 'Corrupted' and needs to be repaired in the Chrome extensions tab.

Chrome: Version 74.0.3729.157 (Official Build) (64-bit)
MacOS : 10.14.5 (18F132)
1PasswordX: 1.16.2
1PasswordX: 1.15.x (what ever the latest was, I switched to the beta to try to solve this. did not work Stable and beta exhibit this Corruption issue)
1Password 7 Version 7.3.BETA-14 (70300014) 1Password Beta

It will run fine for several hours, but eventually quits and shows 'corrupted' message in the extensions tab and needs to be repaired.

    Hi @Houdini7! Welcome to the forum!

    Do you have any other Chrome extensions that could be interfering with 1Password X? Or perhaps some security software installed on this device?

  • Thanks for the reply @ag_ana, that's the process I'm slowly working through now. (as it takes a while for the extension to trigger a corrupted state, this takes a long time :) )

    @Houdini7 – Sounds good! Keep us posted. :)

  • After many different configurations the extension is still becoming corrupt.

    The latest configuration is very basic:
    Fresh install of Chrome: Version 74.0.3729.169 (Official Build) (64-bit)
    Fresh install of 1PasswordX: 1.15.2
    No other extensions
    No Mac client (uninstalled completely)

    After working for 1-2 days, the extension will become corrupt.

    @Houdini7: I've never even heard of this before. Could you please clarify what you're seeing? If it's simpler, take a screenshot of this. To include it in your reply, simply click the document button in the top of the comment field, and select the file you wish to share:

    Just be sure not to post anything sensitive, as this is a public forum.

    Also, you didn't answer Ana: Do you have "security" or "cleaner" software that may be interfering or actually messing with the files? Let me know what you find.

  • I will grab a. Screen shot when I get back home.

    The visual symptoms are pretty straight forward however.
    I can tell it’s broken when:
    1) The icon in the browser will disappear when you click on it
    2) The Extension tab of the browser shows the 1Password extension, disabled. With the warning that ‘This extension has likely become corrupted’...
    At that point, I hit ‘Repair’ and it re-installs 1Password, requires me to do the normal 2FA to re-authenticate it to that browser, and all is good for another day or so.

    Note: The icon/1Password work fine, until it doesn’t. And it just disappears and I have to repair the extension.

    I’ll get a screen shot when this happens next!

    As for any security or cleaning software:
    I have Malwarebytes and CleanMyMacX
    However, both of those are on Manual scanning, and I did not run either while this was happening.

    I’ll look into removing both of them to further eliminate possible culprits!

    @Houdini7: Sounds good! :) :+1:


    1) The icon in the browser will disappear when you click on it

    I have never seen or heard of this before: the icon disappearing when clicked.

    The only thing I can think of is that you have both 1Password X and the 1Password desktop extension installed somewhere and you've got Chrome syncing them. When you install 1Password X, it will uninstall the desktop extension if present. So then the question becomes which icon are you clicking? Is that maybe what you've got going on?

    2) The Extension tab of the browser shows the 1Password extension, disabled. With the warning that ‘This extension has likely become corrupted’... At that point, I hit ‘Repair’ and it re-installs 1Password, requires me to do the normal 2FA to re-authenticate it to that browser, and all is good for another day or so.

    Yeah that's really baffling, as it would have to be something outside of 1Password and the browser: neither can or will corrupt themselves.

    However, both of those are on Manual scanning, and I did not run either while this was happening. I’ll look into removing both of them to further eliminate possible culprits!

    Definitely give that a try. Even if scanning is done manually, having them running at all means they're doing something. Though knowing what and why is not easy.

    @Houdini7: Well... Thank you. I guess I am disappointed because your description was spot-on. I thought maybe the actual error would reveal some additional details. Does clicking it get you anything more?

    I was researching this a bit, and there's nothing definitively helpful. But a few highlights are:

    • Can be caused by missing update_url value in the extensions manifest.json. We have that...but it's possible that something is modifying or removing it on your system. It's just odd that we haven't seen other reports of this, if it's caused by specific software.
    • Can be caused due to a false positive with Windows Defender, which quarantines it. Again, that's built into all Windows 10 installs, so I'd expect this to happen a lot more...and you're not even on Windows!

    The only thing that makes any sense to me is that there were apparently many cases like this with another password manager a couple years ago. So my theory is as follows:

    1. 1Password uses encryption, as does malware, especially ransomware, so it tends to get flagged more often than some other software
    2. While the 1Password desktop extension doesn't actually have any cryptographic functions built into it (all of that is handled by the desktop app), 1Password X is designed to be entirely self-sufficient, so it does
    3. 1Password X is also relatively new, and we even just released a big update this month
    4. Antivirus software is relatively rare on macOS, so (inline Windows) there's less opportunity for users to encounter issues like these and, therefore, to report false positives to the vendors
    5. Something modifying the extension would cause this error, but...
    6. The browser has an index of extensions, so it will know it's looking for this one even if it's been removed completely; if it's missing, it can just download a fresh copy when you "repair" it if necessary

    And then the whole cycle starts over again.

    Based on what we know and what we have ruled out so far, I would bet that if you remove 1Password X and use the 1Password desktop extension, this doesn't happen. However, in the interest of science, I'd like you to try the following:

    Keep using 1Password X. The next time this happens, find out if it's just bee blown away completely by going to Chrome's extensions in Finder:

    ~/Library/Application Support/Google/Chrome/Default/Extensions

    ⌘ ⇧ G is a handy shortcut to get there by pasting that. You're looking for this folder:


    That's the stable channel of 1Password X. Maybe you see something like this, but missing a few things:

    Everything there is 9,862,843 bytes (10.9 MB on disk) for 438 items for me...but yours may vary no matter what because you have different stuff cached, etc.

    Or you may find that all of that is missing. Either way, something missing would confirm a) something is removing files, and b) that's why you're running into this error. Then it's a matter of narrowing down what is doing that by trial and error. Is there a log of activity for that software? I would imagine if they're quarantining something, there would be a way to find out what and why. Let me know what you find!

  • So we're getting somewhere.

    This AM, I found the Extension was corrupt AND The Directory EMPTY!

    So now I'm on a hunt to understand why that happened.

    That's super interesting, @Houdini7. You mentioned you have Malwarebytes and CleanMyMacX installed, but they're set to manual scanning. Do you know of any other utilities that could be altering the files in the 1Password X Chrome extension folder that you may have installed?

  • I think I figured out what's causing this...

    I turned Off Google Chrome Synching. And all has been OK for the last 2 days.
    I found this symptom when googling for 'chrome extensions disappearing' and apparently some corruption in Google's ability to keep multiple Chrome extensions synched across devices 'could' cause this...

    There is no obvious explanation for this behavior, as synching should have Enabled 1 Password to be ON across all my devices, not to remove it randomly...

    I'm going to monitor this longer, but we seem to be making progress

    Excellent detective work @Houdini7. Please do keep us in the loop on this. We'd love to better understand what is going on here so if other customers run into this in the future (fingers crossed for not) we can be of better assistance.


  • So far so good. (Chrome sync still OFF)

    I re-loaded all my normal extensions yesterday. Good so far.

    And for those playing along at home ...
    I had not only un-installed Maywarebytes and CleanMyMacX but still had the issue happen. I also re-installed them, Ran multiple scans / cleanings (including Chrome) and those actions did Not produce the error. (also supporting the theory that the Chrome Sync is 'bonkers' somewhere :) )

  • Well, that did not last long.

    Chrome sync still off and the Directory is gone! (obviously the extension was not working either)

    Back to the drawing board...

    The only other thing that I suspect may be at play are the 2 options that I set in 1PasswordX.
    1) Never lock
    2) Update to the new Look

    I'm going to leave those as defaulted and see what happens

    @Houdini7: Very interesting. Thanks for following up! I've seen plenty of interesting issues with Chrome adding extensions to other machines due to syncing, but never had anything like that happen. :)

    The only thing remotely close to that I can think of is that 1Password X will disable the 1Password desktop extension if the latter is present when installing the former...but not vice versa, and that doesn't cause errors.

    So at this point I'd be willing to bet it's something entirely outside the browser, since the folder is being removed right out from under its nose (so that it still expects to find it). Other than automated overzealous "security" or cleaner" software running in the background, I'm not sure what would do that. Are you sure you don't have a remnant of something else even hanging around? Some of that stuff can be hard to even remove completely. I'd check Running Processes to see if anything there stands out.

  • ** SOLVED **
    Root Cause: a Program called "Coherence Pro"
    This app will create a Mac App from a browser/website. (it's actually a really nice tool)

    Coherence was Not playing nice with the Chrome Browser Extensions after a recent update.
    This caused the browser (in the Coherence made app) to try to 'sync' its extensions locally (on my machine)
    As I had NOT wanted to give 1PasswordX access to the app that I made from the Coherence tool, I told it to Not include any extensions. Consequently, it was now in conflict.

    I have manually synched all my Coherence made Apps and All is well now!

    I know this is a Really small Edge Case, but good to know for anyone that uses any 'Browser to App' program (Coherence is just one, Fluid used to be another, not sure if that's still around or not).

    Ohhh wow. I never would have even thought to look at something like that. I've never used that particular app, but had others like that over the years. Thanks so much for the update! That may help others who run into a similar issue. :)
