Cypress cannot connect to Firefox 105

Same for Windows users. |
|
I am on mac (macOS Monterey). Getting the same issue on firefox 105: Still waiting to connect to Firefox, retrying in 1 second (attempt 36/62) Using it from the UI (npx cypress open). |
|
@cgraham-rs We are worried there has been a regression in firefox. Previously this issue was fixed in this ticket https://bugzilla.mozilla.org/show_bug.cgi?id=1774476. That is firefox v103. Can you please try running against firefox 103 and confirming if youre still seeing the same issue? That would confirm it is most likely a regression in firefox that needs to be addressed. |
|
@nagash77 Our CI process always installs the latest browser versions during setup. Cypress 10.7.0 absolutely worked with Firefox 104.0.2, and then Cypress 10.7.0 broke with Firefox 105.0 I then re-tested with Cypress 10.8.0 to confirm it appeared to be the browser version change as the cause fo the breakage. |
|
@cgraham-rs thanks for confirming our suspicions. We are going to check with firefox to see if they are aware of this issue. I would encourage you to do the same. I will close this issue since this appears to be a problem on the firefox side. |

|
@nagash77 The Firefox team is asking a lot of technical questions about Cypress that I do not have the knowledge to answer. |
|
@cgraham-rs thanks for getting that rolling! I have asked a couple of our engineers to keep an eye on the thread and attempt to answer whatever they can. |
|
We are still facing this issue.. do we have any workaround ? |
|
@nagash77 The Mozilla team seems very active with a lot of technical questions and proposals. Can someone from Cypress please interface with the Mozilla team to help expedite? https://bugzilla.mozilla.org/show_bug.cgi?id=1792088

|
I'm not sure if they'll read closed issues |
|
@403-html we absolutely try to read them all 😸 @cgraham-rs I am still working internally to find the right expertise to help keep moving this issue along. |

Cypress cannot currently connect to Firefox 105. Mozilla has proposed changes to enable Cypress to successfully connect to the right host and port. Per Mozilla:

@nagash77 Some movement on the Mozilla side with nightly build for FF 107 that works with Cypress 10.7.0 See here: https://bugzilla.mozilla.org/show_bug.cgi?id=1792088 |

Note that https://bugzilla.mozilla.org/show_bug.cgi?id=1792088 is fixed now and will be part of the 107 release. That means that the upcoming Firefox 106 will still be affected, but 107 beta releases will work once released.
Probably it should be also enough to just move this line to after |
|
Maybe someone could update the summary of this issue to mention that this only happens when IPv6 is resolved first? Thanks. |
|
Thanks for the update @whimboo! We also plan on resolving this in Cypress for next week's release.
Unfortunately, having IPv4 listed first doesn't seem to work (my host file has always listed IPv4 first). |
That's great! So I assume you fix it in a way that when |

The code for this is done in cypress-io/cypress#24155, but has yet to be released. |

Yep! |
|
Can this fix not get released any sooner? it is a rather major issue and blocking us |
|
The fix should be released today. In the meantime you can try this workaround #23897 (comment) |
|
thanks @mschile sounds good. That fix doesn't seem to work for us not sure why. On latest Cypress and Firefox 105. |
|
@Phonesis, you can also install a pre-release version to resolve the issue. 0e62696#comments |

The issue is still happening. Using Firefox v105 and Cypress v10.10.0. Now what happens is that using cypress open the page gets loaded - but it is blank. It does not able to load specs at all. I need to add manually in the url "/specs/" and reload the page, then the specs are loaded properly. However, when running in headless mode, I get: Which most likely has the same issue. |
|
@mschile Still we are unable to connect to firefox 105 |
|
@audriusnavickasDB, @jpatil14, sorry that you are still not able to connect to Firefox. I tried again locally and I am able to connect and run a spec on my machine. What OS are you using? Could you also run Cypress with these debug logs turned on: |
|
Released in 10.10.0. |
|
@mschile Ok, did a bit of more playing around, so apparently it looks like it started working properly when using base url as localhost or any other https://... url. However the issue I have described happens when base url contains credentials like this: https://test:test@google.com |
|
@audriusnavickasDB, thanks for the update. Since this appears to be a separate issue, could you please log a new issue. |
