*please ignore formatting issue

trigger:
 - none
parameters:
- name: stg
displayName: "Environment Names"
type: string
 
pool:
  vmImage: ubuntu-latest
stages:
  - stage: stage1
    displayName: 'Stage C1'
    jobs:
    - job: jobabc
      strategy:
        maxParallel: 2
        matrix: 
            env_1:
                EnvironmentX: E1
                Browser: IE
            env_2:
                EnvironmentX: E2
                Browser: Firefox
            env_3:
                EnvironmentX: E3
                Browser: Chrome
    displayName: 'Job 1'
    condition: contains('${{parameters.stg}}', $(EnvironmentX))}}  
    steps: 
    - task: CmdLine@2
      displayName: 'My Task '
      inputs:
        script: 'echo Stage C1 $(Browser)'

I pass stg parameter as E1E3E4.

In Matrix I have defined EnvironmentX whose value can be E1, E2, or E3.

Below code runs Job 3 times with matrix values defined.

I do NOT want to run all 3 jobs but stg parameter value should decide JOb would run for which matrix values.

Job Condition is NOT working? How to fix this please

You could build the matrix conditionally. Not ideal but that will work:

trigger:
 - none
parameters:
- name: stg
  displayName: Environment Names
  type: string

pool:
  vmImage: ubuntu-latest
stages:
- stage: stage1
  displayName: 'Stage C1'
  jobs:
  - job: jobabc
    strategy:
      maxParallel: 2
      matrix:
        ${{ if contains(parameters.stg, 'E1') }}:
          env_1:
            EnvironmentX: E1
            Browser: IE
        ${{ if contains(parameters.stg, 'E2') }}:
          env_2:
            EnvironmentX: E2
            Browser: Firefox
        ${{ if contains(parameters.stg, 'E3') }}:
          env_3:
            EnvironmentX: E3
            Browser: Chrome
    displayName: 'Job 1'
    steps: 
    - task: CmdLine@2
      displayName: 'My Task '
      inputs:
        script: 'echo Stage C1 $(Browser)'
