Multiple Browser Contexts using CDP

[Mor Amrani]

Hello,

Is there a way to create multiple persistent profiles/Browser Contexts using CDP?

Target.createBrowserContext method description indicates that the new browser context is similar to an Incognito one and this is well represented by the code:

Incognito profile when using headless -https://source.chromium.org/chromium/chromium/src/+/main:headless/lib/browser/headless_devtools_manager_delegate.cc;l=89;drc=03d319de4351bb6ad328e34fded98f6c4b62e65a;bpv=1;bpt=1

Off-the-record profile when using headful -
https://source.chromium.org/chromium/chromium/src/+/main:chrome/browser/devtools/devtools_browser_context_manager.cc;l=52;drc=03d319de4351bb6ad328e34fded98f6c4b62e65a;bpv=1;bpt=1

Is there a reason for not using regular profiles?
Is there a plan to support this?

Thanks,

Mor

You can use existing profile folders using --profile-directory (assuming --user-data-dir also points somewhere existing). More: https://github.com/GoogleChrome/chrome-launcher/issues/172#issuecomment-555277231

AFAIK you cannot create/select Chrome profiles over CDP.

Thank you Paul, this is very helpful!

I have managed to use multiple profiles with the same browser process when running headful. However, this doesn't work for me when running headless.

Is it fair to say that the browser must be launched in headful mode in order to use the --profile-directory option?
