Describe the bug
The bug is coming up sporadically and only firefox shows that error. ReRuns are mostly successful, so not sure if i am doing something wrong. But before in 1.1.1 version we didnt see this issue anytime from last 1 month

Add any other details about the problem here.

Thanks and let me know if am doing something wrong here, webkit and chrome works fine and firefox also gets this error 1 out of 5 times now

@pavanreddy61 Sorry for the late response! Does this still happen with the new Playwright version like 1.6?

[pavelfeldman]

We seem to be late to collect feedback from the customer. Could you check it against 1.6 and file a bug linking this one if it still persists?

Hi, sorry to necrobump this, but I am encountering this issue in playwright 1.8.0 when multiple firefox instances are spawned in parallel on a kubernetes pod:

      Failed to start browser "firefox": browserType.launch: Timeout 30000ms exceeded.

      Note: use DEBUG=pw:api environment variable and rerun to capture Playwright logs.

This should be fixed with #5514 that disables crashrerpoter altogether in our builds. The fix will be released in v1.9.0

We having the same issue with playwright@v1.10.0 running under Ubunto 20 using mcr.microsoft.com/playwright:focal

@skyuplam is it reproducible for you? If so a minimal reproducible would help a lot to fix this bug.

[skyuplam]

Hi @mxschmitt , thanks for your response. We have managed to fix the issue via setting higher timeout value. Launching Firefox headless mode in Linux is slower than the previous version we used. Anyways, thank for your attention.
