Steps to reproduce:

(async () => {
  // Create tab
  const tab = await browser.tabs.create({ url: 'https://example.com', active: false })
  
  // Wait
  await new Promise(done => setTimeout(done, 2000))

  // Close tab
  await browser.tabs.remove(tab.id)

  // Create new tab (it will force Firefox to move the reopened tab to previous position)
  await browser.tabs.create({ active: false })

  // Listen
  browser.tabs.onCreated.addListener(tab => console.log('TAB CREATED, id:', tab.id))
  browser.tabs.onMoved.addListener(id => console.log('TAB MOVED, id:', id))

  // Then open Menu / History / Recently closed tabs
  // And middle-click on the first "Example Domain" item
})()

Actual results:

Console output:

TAB MOVED, id: 7
TAB CREATED, id: 7

Expected results:

Console output:

TAB CREATED, id: 7
TAB MOVED, id: 7

Hello,

I reproduced the issue on the latest Nightly (117.0a1/20230716213402), Beta (116.0b6/20230716180334) and Release (115.0.2/20230710165010) under Windows 10 x64 and macOS 11.3.1.

Proceeding with the STR, the console output first logs TAB MOVED and then TAB CREATED. Opposite of what the expected results should be, as per Comment 0.

Fore more details, see the attached screenshot.

FYI: This is not the only bug where onCreated behaves unexpectedly - see bug 1763927 for another example.
