I've been developing a mobile-biased web app which will have to load quickly on patchy 3G networks. As such I've been very economical with page weight. Now we're putting the finishing touches on the project I'm looking at adding a favicon, largely for the benefit of desktop users. Even though it will only be a few kilobytes I don't want this file to have any negative impact whatsoever on page loading, especially when it won't be much use to the majority of users.
If a user is using iOS safari, the Android Browser or Chrome on Android will the browser actually request the favicon, and if so is the favicon request deprioritized at all to make sure everything else loads first?
Just to clarify I'm talking about the favicon.ico file, not the apple-touch-icon mobile specific icons, which I assume to be loaded on demand (i.e. when you add a page to your home screen)
If you have a favicon.ico file with its declaration in the HTML code, iOS Safari and Android Chrome won't load it (tested on iPad Mini and Galaxy Nexus).
However, if you have Apple Touch icons, they will be loaded immediately by some browsers, not when the page is bookmarked or added to home screen:
iOS Safari waits for bookmark or add to home screen events. Good.
Android Chrome loads apple-touch-icon-152x152.png on page load. Arguable.
If network performance is a major issue to you, you should either study the behavior of various devices... or remove all the extra icons.

I'm using Font Awesome 5 Free via a kit. On desktop, the icons work perfectly. But on mobile (iOS chrome (normal and incognito), iOS firefox focus, iOS safari), they behave like Schrödinger's cats...
On first page load, the icons appear. Tap reload and they disappear and are replaced by small squares. Tap reload again and they reappear. Every other tap of reload shows or hides the icons.
I notice the same behavior if I toggle back and forth between "request desktop site" and "request mobile site". (I'm not sure what's really going on under the hood there since the page renders the same either way.)
Since they do appear correctly, at least part of the time, I don't think it's a cross-origin problem or a caching problem.
An example page is here: https://onlinesafetyzone.com/learn/learning-zone.php
I've read many posts, here and on GitHub and none of the solutions has worked. Anyone have a clue what's going on?
It seems you have somekind of a XSS issue. I would try to download the fontawsome resources and deploy them with the application. Can be that they have a CDN problem, every second time the fonts break :| so maybe one of the nodes is flipping.
Since I don't have an Iphone. I have to test my site using site that there's available IOS tester.
I have reports that the site is not loading properly on Iphone.
Link: https://adthrone.com
But in the android version it works properly.
But in IOS not working properly
This is some details about the reports
The whole index.php is not loading (Blank page)
Sometimes it loads but some parts of the css/html of the page is missing.Like site logo in the navigational bar.
Sometimes the index.php loads but have multiple html/css issues
Android version works properly but not IOS.
The client has the following
Good internet connection
Have android & iphone for testing
Currently the site contains the ff:
Low quality images with file size of KB
Used bootstrap for front end
I just want to know the facts why this site is unstable when it comes to IOS mobile version.
I have a simple website containing 3 HTML pages but sometimes internal links on IOS Safari doesn't work correctly. Rather than rendering the page, it displays the 'Open in "Drive" screen with options to save page as a document. When I refresh the page it renders correctly again. This usually when I navigate around the pages quickly and I am not sure why this odd behavior and how to fix.
See a screenshot here https://ibb.co/bXxzZTS
Not sure if it is related but the DNS is via CloudFlare (Free) and the pages are really fast (as it's just HTML, CSS and JS).
I have only seen happen on iPhone Safari. Other devices I have checked on include iPad, MacBook, PC running browsers Chrome or Safari are all OK.
Additionally, I tried using URL with and without full domain with the same result.
I just expect the page to render as an HTML page.
I'm not an expert in web and I composed and updated my website recently. I ran all the test that I could on DreamWeaver CC and tested on multiple mobile devices (tablet, android and iphone); all seems to work fine. Until I uploaded the site to my server, the site start to act weird.
1st problem:
It is a portfolio website with individual pages to corresponding projects. On each project page, the first image on the lightbox has always gone missing; but clicking into the lightbox I can find the missing image (the preview image and the lightbox image share the same source so if the lightbox can find the image it implies that the image is on the server and the path is correct).
2nd problem:
when the browser is shrink below certain size, a toggle menu will replace the content on the header, clicking the toggle menu will show a pop up menu to site links. For some reason, after uploading the site to server, the toggle menu pop up never work.
3rd problem:
The above problem is never apparent on desktop browser(all image shows up correctly; toggle menu works). To make the problem more complicated, I can't confirm if it is device or browser oriented problem. For example, the site works on chrome browser on my iphone and nexus 5(android), but problem occurs on my xperia tablet(android) chrome browser; on my xperia tablet, the site works perfectly on firefox.
Does anybody has any idea what the potential cause to the problem, and perhaps a direction to a solution?

Thank you for your time and look forward to any reply.
Looks fine to me (Google Chrome), you need to use media queries for some certain resolutions. You also need to use some cross browser css tags lide "-webkit, -moz, -o" etc.
I'm currently working on one of my first two projects and you can tell that I'm still at the beginning of my youtube-tutorials-&-SO-powered learning journey:
our neighbor's skin & beauty spa
Please don't be too harsh on my code :D I've hand-written everything from scratch in a little editor.
In short, everything seems to work A-OK on desktop computers (I tested FF and Chrome), but on the iPad and other tablets I'm experiencing nasty bugs - I'm having major trouble with two issues:
the Google Maps iframe is always visible (overlaps other
sections) on tablets even if the corresponding section isn't clicked
on in the menu, and I have no idea why! It seems that the
visibility:hidden on a position-fixed element isn't interpreted
correctly?
:focus works on the image gallery 'sneak peak', but
in the services section, the 4 sub-content areas are inaccessible.
(Unrelated?) When the page loads on my iPad (mini) the #logo_box
div appears at page load, but turns semi-transparent the very
instant as the map iframe appears.
EFFORT1: I removed the Google maps iframe-containing 'content' container altogether, and suddenly the :hover on the other content sections stopped working as well. This might be an indicator that something is 'linked' in a way that's not right...
EFFORT2: I assumed that the < label> is the culprit, but I can't pinpoint it. I tried this suggested solution, but it's for IOS4 (2011), and as Rob Fletcher commented last Feb., it doesn't work on IOS7.
EFFORT3: I feel that the .content div's {visibility:hidden/visible;} is causing trouble in the android mobile browser: input:checked hides instead of reveals the particular section while all others show.
Btw, how do I friggin' trouble-shoot tablets? I don't have any dev tool on ipad & android browsers.
Help is much appreciated!!
On iPad, you can go into the Settings App, then go Safari -> Advanced -> Web Inspector.
Then plug it into your Mac via USB and open Desktop Safari on the Mac. If you haven't already enabled the Develop menu, go Safari -> Preferences -> Advanced -> Show Develop Menu.
Then when you open a web page in Safari on the iPad, you can connect to it via the Develop menu on your Mac's Safari and use the web inspector.
If you're using Chrome on Android you can use remote debugging https://developer.chrome.com/devtools/docs/remote-debugging
Weinre provides similar functionality across more platforms (including Android native browser), but is a bit more involved to set up.
