Dear Vicky,
Adobe Analytics is not capturing the Extensions Details by default. If you can capture these details using JavaScript and store it in Custom Variable, you can definitely create the segments you need.
Check with your developer whether they can code to capture the Extensions Detail for an Browser, if can, everything can.
I saw the below links while surfing:
How to detect if a Chrome extension is installed - Twilio
Detecting Google Chrome Browser Extensions - Stack Overflow
Thank You
