Hello,
You are welcome.
1) Go to Static Blocks and edit the footer static block according to your needs. We enabled support of SVG icons on your site, so you should not have problem with the footer svg anymore.
2) Increase width of the element of your header connection block that includes the Account icon because there is no space to show all in 1 line. Check now.
3) Read this post https://xstore.helpscoutdocs.com/article/100-how-to-speed-up-my-website
