[Feature]: Firefox-ESR Support

[dominikschopper]

🚀 Feature Request

we need Firefox ESR support in playwright, should work pretty like the channels for other browsers (edge ...)

Example

No response

Motivation

I do think its relevant. if you need to support the esr release, you will need to run your e2e tests against that release. there are companies that restrict their users to use the esr release and thus you need to test

There was the feature req 27542 for this that was not upvoted enough ... #27542

Our company too limits the client machines to the ESR Versions of FF. This feature would be helpful.

[ruihildt]

Both Tor Browser and Mullvad Browser are ESR based, so this would be helpful for testing in that context.

[t3chguy]

@ruihildt Playwright has to use modified builds of Firefox to be able to function so it supporting ESR wouldn't inherently gain you ESR-fork (e.g. Tor) support unless you were to make those same modifications and builds there yourself.

It is planned to include support for Firefox ESR? It will be helpful for a lot of people.
Not every company supports only the latest browser version. Please, try to think about implementing it for the playwright. It is a perfect tool but it's a pity that this is not supported. Please implement this :)
