One of our clients has reported unusual behavior while using this extension to track / develop a website and the associated webapp.
Seems like the extension has been modified to inject tracking [that’s the least we found out from our quick investigation]. A part of the code used can be found here:

We recommend anyone using this extension to uninstall it and carefully investigate.
One way of debugging what’s running on the ESP is using the UART console. But there is a trick — it might be locked at 74880 baudrate.
There’s a quick fix. Modify the user_main.c and add:
#include "driver/uart_register.h"
on top of it.
Also, in the main loop(user_init) change
void user_init(void){
os_printf("SDK version:%d.%d.%d\n" SDK_VERSION_MAJOR, SDK_VERSION_MINOR, SDK_VERSION_REVISION);
with:
void user_init(void){
uart_div_modify(0, 115200);
SET_PERI_REG_MASK(UART_CONF0(0), UART_RXFIFO_RST | UART_TXFIFO_RST);
CLEAR_PERI_REG_MASK(UART_CONF0(0), UART_RXFIFO_RST | UART_TXFIFO_RST);
os_printf("set baudrate to 115200\n\r");
Modify the 115200 with the value you want to use, but we suggest using some standard ones, like 38400, 57600 and 115200.
