Browser not updating
In the same way that your web browser has a cache of recent web pages, your Internet Service Provider (ISP) may be doing some caching on your behalf.In some (rare) cases, even though you are using shift-refresh to get new data from a webpage, the pages still seem to be old.In order to speed up web browsing, web browsers are designed to download web pages and store them locally on your computer's hard drive in an area called "cache".Browser cache (also know as Internet cache) contains records of every item you have viewed or downloaded while Internet surfing.So when you visit the same page for a second time, the browser speeds up display time by loading the page locally from cache instead of downloading everything again.Although storing Internet cache makes web browser faster as it usually takes your computer less time to display a web page when it can open page's elements or even the entire page from your local Temporary Internet Files folder, You sometimes want to overrule the Internet cache, for Example to see changes you made to a webpage you just uploaded.
This will take you to the app store, where you can update all the software with available updates, include Safari.Both Firefox and Safari seem to not care about refreshing to reflect the changes. Even if I upload the new file to the server and refresh in FF it is not showing the new code styles, I have emptied cookies. If that doesn't work, does renaming the HTML document work? Regardless, this should not be a problem - I think Chrome and Firefox are both smart enough to read timestamps of local files to see if they've been modified since they were last loaded. You're using a browser which is not supported by at the moment.Probably because you're holding a tablet or phone right now or you just upgraded to Windows 10.
