Absolutely all modern browsers cache your site!
What Is A Browser Cache?
The browser cache is a temporary storage location on your computer for files downloaded by your browser to display websites. Files that are cached locally include any documents that make up a website, such as HTML files,
CSS style sheets,
JavaScript scripts, as well as graphic images and other multimedia content.
HOW TO FIX?
Clear your Browser cache!
Ctrl-
Shift-
Delete (Windows) or
Command-
Shift-
Delete (Mac)
NOTE!
1. Be sure that all
Joomla! cahing and
optimization (JCH / JOT) plugins -are
disabled
2. Be sure that cache is not enabled on your
hosting or if you are using services such us
CloudFlare, them should be also disabled
All caching plugins for speed optimization can be enabled after the website is ready and you don't edit the page. Otherwise, you will have to constantly clean your browser's cache and cache of your site
