Error `Runtime.addBinding` with Chromium 66

[MikeMcC399]

Current behavior

Cypress fails to run with Chromium 66. The error is

'Runtime.addBinding' wasn't found

Desired behavior

Cypress should run with Chromium 66 since the documentation states:

Cypress supports the browser versions below:

Chrome 64 and above. Chrome 80 and above is required for cypress open usage.

Test code to reproduce

Set up default Cypress project with single example spec.

Install Chromium 66 into project with

npx @puppeteer/browsers install chromium@540276

Run Cypress

npx cypress run --browser ./chromium/linux-540276/chrome-linux/chrome

Cypress Version

13.14.2

Node version

v18.20.4

Operating System

Ubuntu 22.04.4 LTS

This is very unlikely to be addressed. We intend to drop support for these versions as soon as next quarter: #29977

This is very unlikely to be addressed. We intend to drop support for these versions as soon as next quarter: #29977

I appreciate that it is unlikely for Cypress to be able to support Chromium 66 again.

I did some further tests and found that Chromium 79 doesn't work either with Cypress 13.14.2 in run mode. It times out:

Timed out waiting for the browser to connect. Retrying...
The browser never connected. Something is wrong. The tests cannot run. Aborting...

I went back to previous Cypress versions and found that Cypress 11.2.0 was a working version for Chromium 79 and it failed on Cypress 12.17.4.

Should there be any documentation changes made due to this situation? The documentation says that Chrome 64 - 69 should work in run mode, however that appears only to be true for Cypress 11.x, not for Cypress 12.x or 13.x.

• Documentation resolved through cypress-io/cypress-documentation@b4ed11f and queued for release with 14.0 Docs cypress-documentation#5964

[MikeMcC399]

This is a stage: wontfix Cypress does not regard this as an issue or will not implement this feature item.

Cypress 14 will say:

Cypress officially supports the latest 3 major versions of Chrome, Firefox, and Edge.
(For example, if the stable release of Chrome was 130, Cypress would officially support Chrome 128, 129, and 130.)

The current stable release of Chromium according to https://chromiumdash.appspot.com/releases is 131, so this excludes Chromium 66 by implication.
