Zoho SalesIQ affects GTMetrix results: fully loaded time increases by 15 seconds

We have been using Zoho for a few years and we are generally very happy with the product !

We have recently started to use Zoho SalesIQ on our website and we have this problem though:

- before added the SalesIQ widget to our website, GTMetrix shows a "fully loaded time" of 6.5 sec on Firefox



-after we add the Zoho SalesIQ widget, there is a large increase in the "fully loaded time". It goes up up to 22.7 sec


- lastly, there is absolutely no problem when testing on Chrome, with or without Zoso SalesIQ widget, the fully loaded time is just as short.
What do you think about this issue ? Is this a known problem ? Any thoughts on why this could be happening only on Firefox ? And do you maybe know of a workaround ?
