A few creative ways are using a sandbox application such as Sandboxie, or alternatively run the Flash installer inside a virtual machine using a program such as Virtualbox.

Things get a little tricky if you have no access to the dll file locally and don’t want to download it because the Flash plugin needs installing for you to get hold of it. There are ways to get around this problem if you want to use Flash with a portable Firefox or Opera, but they all have one thing in common, which is you will at some point need the Flash Player plugin installed on a computer somewhere to get the needed files as they can’t simply be extracted from the setup installer. If you don’t want to manually enable support for Firefox or Opera, simply download and use Google Chrome portable. There is however, one popular browser that’s had built in Flash support for a couple of years. One of the plugins you can add is one to enable Adobe Flash Player support, but the problem being there isn’t a portable version of Flash to use in the portable browser.

Portable applications such as the Firefox and Opera web browsers are very popular these days and they make use of plugins to add components to the browser. There are many computer users around who don’t like Flash and refuse to have the player installed because of various security concerns or performance related issues, and other users just don’t need or want it installed because they don’t view Flash content.

Even though video sharing websites such as YouTube are switching many of their videos to HTML5, there’s no doubt that the Adobe Flash format is still hugely popular and commands a large share of the market.
