Hi @tommy,  
**Gallery view in Firefox breaks whenever there are multiple users in a session.** We also tried in our app where we are integrating the instant sdk right now, but to no avail.  
**This issue seems to be exclusive to Firefox as Google chrome is working perfectly, apart from the (video restarting issue of chrome (CS-3160)).**  
Need assistance on this matter as firefox is a prominent browser with a significant user base.

**Which Fully Customizable Web SDK version?**  
Instant web sdk version- 1.0.2

**To Reproduce(If applicable)**  
Steps to reproduce the behavior:

1. Start the sample app in Chrome
2. Start video
3. Repeat 1 & 2 in incognito a couple of times simulating multiple users
4. Join session in Firefox

**Result:**  
Gallery view broken in Firefox but ok in Chrome.

**Device (please complete the following information):**

- Device: Desktop
- OS: Ubuntu, Windows 10
- Browser: Firefox
- Browser Version - version-86

Please see the attached the screenshots.

Hey @hasan.md ,

I have confirmed with our engineers that the Fully Customizable SDK gallery view is only supported in Chrome at the moment.

We will be updating the docs.

Thanks,  
Tommy
