@Md.lbrahim by looking at the comment replies of you above, it seems that Glimpse is indeed active and rendering its <script>
tags.
Can you check with the browser developer tools whether the Glimpse client is actually rendered at the bottom but maybe hidden by another element that has a higher z-index?
If you still can't get the HUD to show up, then maybe create an issue on our issue tracker and try to provide as much details as possible (browser used, versions, other installed packages that might interfere with Glimpse rendering etc...)
