reCAPTCHA dialog does not appear

I encountered a website today for which the reCAPTCHA dialog wouldn't appear. This is not a case of the endless blue circling of the reCAPTCHA screen. In this case, the reCAPTCHA screen does not appear at all.

I thought it was a problem with my account at the website since nothing happened when I clicked LOGIN. It wasn't until I tried Edge and the reCAPTCHA dialog appeared that I realized the problem was not with the website, but with Firefox not presenting the reCAPTCHA dialog.

I do not know whether the problem is with the site specifically since I have not encountered any other sites recently that required reCAPTCHA authentication.

Thanks... bms

Currently running Firefox v125.0.3 (Standard Browser Security) on Windows 11 Pro (v10.0.22621 Build 22621)

Chosen solution

It appears that Google has fixed this recaptcha issue for Windows Firefox users. You can change Firefox useragent back to the default if you did the temporary workaround by changing it with a useragant extension or by preference in about:config

If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block content (Adblock Plus, NoScript, DuckDuckGo PE, Disconnect, Ghostery, Privacy Badger, uBlock Origin), always make sure such extensions do not block content.


You can try these steps in case of issues with webpages:

You can reload webpage(s) and bypass the cache to refresh possibly outdated or corrupted files.

  • hold down the Shift key and left-click the Reload button
  • press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
  • press "Command + Shift + R" (Mac)

Clear the Cache and remove the Cookies for websites that cause problems via the "3-bar" Firefox menu button (Settings), click the padlock icon (Clear cookies and site data) for the domain in the selected tab.

"Remove the Cookies" for websites that cause problems:

  • Settings -> Privacy & Security
    Cookies and Site Data: "Manage Data"

"Clear the Cache":

  • Settings -> Privacy & Security
    Cookies and Site Data -> Clear Data -> [X] Cached Web Content -> Clear

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or if userChrome.css/userContent.css is causing the problem.

  • switch to the Default System theme: "3-bar" menu button or Tools -> Add-ons -> Themes
  • do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window

You can check for issues with Enhanced Tracking Protection. Firefox shows a purple shield instead of a gray shield at the left end of the location/address bar in case Enhanced Tracking Protection is blocking content.

  • click the shield icon for more detail and possibly disable the protection

You can check the Web Console for relevant-looking messages like blocked content.
