net.portswigger.devtools.client.ah: Unable to start browser:

Chris | Last updated: Apr 05, 2022 10:35AM UTC

I am sorry, I am new to BurpSuite and am trying to use the Community edition on Windows/10 64bit. I am on the "Proxy" tab and have "Intercept is on". When I click the "Open browser" I get this error message: Burp Browser Error: net.portswigger.devtools.client.ah: Unable to start browser: I have Microsoft Edge, Firefox, Vivaldi and Brave browsers installed. I do not have nor want Google Chrome installed. What is the reason for this error? How can I fix it? Regards, Chris

Hi Chris. Just to clarify, is that the only text displayed when you see the error message? In addition to the above, are you able to provide us with your diagnostics information? You can find this by going to "Help > Diagnostics" within Burp.

Liam, Sorry, I did not copy the rest of the error message. However, when I closed Burp Suite down and restarted it, the browser appeared OK when requested. I guess it must have been an initial setup issue. Thanks anyway, Chris

Thanks for letting us know, Chris. Please let us know if you need any further assistance.
