Hey, thanks for the report. This looks like a bug in Cursor 2.0.38’s browser tab feature. We’ve seen a similar report here: Cursor 2.0 In app browser is not opening website

Could you please share:

• A screenshot of the certificate error you’re seeing
• Whether this affects HTTP localhost or only HTTPS

In the meantime, I’ll pass this to the team. As a temporary workaround, you may need to use an external browser for local development until this is fixed.

@deanrie

Whether this affects HTTP localhost or only HTTPS

I think it has something to do with the expiration of the certificate.

[deanrie]

Thanks for the screenshot. This confirms the certificate issue we’re tracking.

Good news, fixes for the browser tab issues are already available in version 2.0.43. Please update and let me know if the issue persists.

[yi_zhang]

Thank you for your quick support. I haven’t seen the latest（2.0.43） download address in official website. Please send it to me！！

[deanrie]

This version isn’t available for direct download yet, but you can install the update from Cursor.

Go to Cursor → Check for Updates
Or open the Command Palette (Cmd+Shift+P) and search for “Attempt Update”

[Renan_Curvo]

I’m with cursor 2.0.43 and I’m still with the same issue can’t trust manually the site.

[gusbsmith (Gustavo Smith)]

Same here, I’d love to manually aprove the site or put the .exe with flags to ignore the certificate issue

[andrewh (Andrew Milich)]

This will be resolved today! You will have an option to trust it.

[yi_zhang]

The website can be trusted manually at 2.0.54.

[gusbsmith (Gustavo Smith)]

Would you mind explaining how? In which section?

[gusbsmith (Gustavo Smith)]

Two weeks later, this is NOT solved. I’d like to bump the issue and for someone to mark it as unsolved in order to keep visibility clean.

[barnes (Barney Dalton)]

Any news on this?

[deanrie]

Hey, status update. The manual “trust this site” option in Browser Tab has been shipped starting in 2.0.54. Please:

• Update to the latest version: Cursor → Check for Updates or Cmd/Ctrl+Shift+P → Attempt Update
• Open the site in Browser Tab and check if a dialog appears to trust the domain

If the dialog doesn’t show or the block remains, please send:

• A screenshot of the current error
• Your Cursor and OS versions (Help → About)
• An example URL and repro steps

[Gustavo_Smith2 (Gustavo Smith)]

I’m answering on a second account since I don’t know why I can’t post it with my main.

I’m attaching an image when you can see the current error, my Cursor and OS version and an example url (ecomm-app. com, which is where I work. We don’t use that domain anymore, since we use www.ecomm-app. com, that one is safe)

Reprodution steps:

Open Browser
type ecomm-app.com and hit enter on the url bar
see this error (no Dialog, no option to manually trust the site)

I am not seeing how to accept self signed certs. Just says restart browser

On cursor Version: 2.2.17

[gusbsmith (Gustavo Smith)]

Bumping the issue, still not solved.

Also not getting a prompt to trust self signed certificate. On Cursor 2.3.24.
