Greetings '''hongchichang'''<br> Slow Internet problem arises not only from the browser and from another data transmission quality. Please measure the speed of data transmission from the browser Firefox and using a third-party browser. Please answer whether there is a difference in data transfer rates when using different browsers? <br> One solution to the problem can - blocking load images or upload images only if there is a connection (setup in setting your browser). Also, if you have installed addons in browser, disable them and make sure the data transfer rate.<br> I hope this answer helped you
