why does Edge launch in Guest/temporary mode with SeleniumBase?

[deepak577834]

Even with uc=False and profile arguments, it doesn’t seem to use a persistent profile (no cookies/session saved).

Is this expected behavior for Edge, or is there a way to force a normal user profile?

Thanks!

Edge needs to use Guest Mode due to #1897 and #1842.

I’m seeing an interesting difference between Chrome and Brave with SeleniumBase + UC.

Flow:
• Create seed profile using real browser (subprocess)
• Clone that profile at runtime
• Launch with SeleniumBase (uc=True)

Behavior:

Brave → works perfectly (profile reuse, no issues)

Chrome → unstable:
• Sometimes URL doesn’t load
• Clicking address bar can crash/close browser

Both are using the same cloning + runtime logic.

Question:

Why would Chrome behave unstable in this setup while Brave works fine?

Is Chrome more sensitive to profile cloning / UC injection compared to Brave?

Any insight would be really helpful 🙏

Could be something related to internal functionality of profiles for different browsers. Regular Chrome may have something in place to handle duplicate profiles a certain way. But hey, if it works for you when using Brave, then just use the chromium browsers where things work the way you want them too.
