[BUG] Firefox new page opens as new window instead of tab.

[shirshak55]

import { firefox, chromium } from "playwright"

async function main() {
  let browser = await firefox.launch({ headless: false })

  let context = await browser.newContext()

  let page = await context.newPage()
  let page1 = await context.newPage()

  await page.goto("https://microsoft.com")
  await page1.goto("https://microsoft.com")
}

async function main2() {
  let browser = await chromium.launch({ headless: false })

  let context = await browser.newContext()

  let page = await context.newPage()
  let page1 = await context.newPage()

  await page.goto("https://microsoft.com")
  await page1.goto("https://microsoft.com")
}

main().catch((e) => {
  console.error(e)
})

main2().catch((e) => {
  console.error(e)
})

Here is screenshot . Clearly code is nearly same with firefox and chromium replaced. But the behavior is weird firefox spawns window which is supposed to be tab. And Chrome behaves properly.

Plus this following code shows 2 window now in past it used to show 1 window with 2 tabs.

  let browser = await chromium.launch({ headless: false })
  let page = await context.newPage()
  let page1 = await context.newPage()

Discovered while upgrading the plugin.

Thanks.

Hey, seems to be a duplicate of #3696

[shirshak55]

nope its not a duplicate. In chrome there is no issue and in firefox there is issue. That 3696 doesn't mention this.

I think it is a dupe, let's keep discussion in a single place. #3696
