"Error" when using Firefox but not Chrome

When using Firefox I will see my mail icon go gray and when I open it all accounts say error. It takes multiple refreshes to get it to work. I do not notice this behavior in Chrome.


  • That's to get logs from Chrome...how about Firefox? That's the browser with issue

  • Go to this url:


    and click inspect beside my gmail extension:

  • it wants to save as a .har file but I cant upload. How best to get the file here?

  • Just a screenshot of any errors and paste them here will be fine.

  • I can email u the har file if u want load it to get more details too

  • Can you disable all other extensions, it seems something is blocking calls to gmail.googleapis.com

  • I disabled all extensions but urs and still have the issue.

  • ok i just pushed a possible fix in v23.3.0.1

    can you force the update with this https://jasonsavard.com/wiki/Extension_Updates

  • i installed the updated....fyi I see this now.....

  • I still get the error. Looking in more detail I see this:


    On the same get that works it:

  • Do you have any other antivirus/malware software running on your machine.

  • Of course.....its a work laptop. I dont have these issues in Chrome is the thing. I run the same extensions.

  • edited October 2022

    When you browse directly to this url with the browser what do you see?


  • 404 error....same in Chrome and FF

  • Can you try reinstalling the firefox extension.

  • Just did...got my first error already

  • Can you verify the extension version is the latest v23.3.0.1

    Other than that have you changed any Firefox settings related to privacy?

  • Verified. No....don't mess with it. I had a proxy setup but removed that. Let me see if I can reset my settings

  • Well a reset didn't help any.....still have the issue even after just adding ur 1 extension. No need to look at this further. I'll just stick with Chrome.
