Recently at steamgift, 1 of my pc missing certain icon. Anyone can help?

You use scripts?

Tried other browsers, what browser does it not work?

It happens sometimes when PC's are getting old or need a cleanup (from viruses, cookies, etc...).

Not talking exclusively about SG: icons dissapearing even in windows ui.

That's my experience of it anyway.

But surely, If you are using scripts (looks like it from the pics) wont help having a "normal version of the website".

My guess is the ESGST addon for your browser got removed or disabled

You can try to sync your account and log out and log in to SG.

Both of my pc using it for long time already. Recently no install nor adding anything.
So many year no problem just last week until now 1 of my pc losing this icon while another pc still ok.
At start I though is steamgift website problem then after wait a few day and the problem still at there, then I start clean all the firefox cache, site data, cookies, still fail. Then I though is some extension-add on in firefox so I disable all then try again still same problem.

Try doing a search for firefox font awesome icons missing and look through some of the results. I have no idea what the issue is, but other people have had the same problem in the past, so maybe those threads will help you find a solution.

I think I found out the problem. I think it related to dns.
I change the dns to 8.8.8.8 and 8.8.4.4 and now all icon show up.
Those old dns which is 1.9.1.9 and 202.188.18.188 I had use for many year without problem. Don't know why now it become problem.
This dns also solve my problem in chrome that cannot display steam website image properly. Don't know why it only happen to chrome while firefox can display steam website properly with old dns.

conclusion
Old dns, my firefox can display steam website properly without problem but steamgift website got display problem(recently only).
Chrome cannot display properly on steam website.

New dns all can display properly.
