Leap Browser Issue

First of all, sorry if this has been addressed before.

I have a Leap running OS version 10.3.2.2876 (10.3.2.2836 Software Release).
The browser is very buggy. It is very slow both on mobile network and WiFi, opening new tabs and closing it takes time.
Is this a common issue or is there any bar file for the browser which i can side load and fix this?

Thank you in advance.

This is not a common issue.

The browser bar file is just a UI. Most of the browser "guts" are baked into the OS itself.

Maybe try rebooting your device, and clear your browser cache first.
