Step: First install the Firefox browser (I started from firefox2.0). You can install a Firefox version for the Selenium IDE plugin. Selenium IDE is not available in any Firefox version.
Second installation, is to install the Selenium IDE plug-in, this you can install Firefox plug-ins by n ways. I often use add-ons directly inside the tool.
Third you may find many plugins about the Selenium IDE. For example: Selenium IDE Buttons. Wait a minute. What I'm summarizing here is the selenium IDE. Then you can directly find the Selenium IDE. Other plug-ins you can also install, but as for the use of their own to explore. If there are good also post summary under.

Basically install the Selenium IDE plugin by installing the above three steps. Be sure to restart Firefox when you're ready to install it. If you are unable to install it may be that your Firefox does not support the installation of the Selenium IDE plug-in, then you will need to find a version that is suitable for selenium IDE installation. I met a lot of problems before. because the Selenium IDE and the version of Firefox are incompatible with the weird issues that arise.

Selenium IDE Usage considerations:
Reference
Since I started using the Selenium IDE plug-in from the firefox2.0 version, I encountered an unexpected problem with the Selenium IDE plug-in that could not be used or in the process of testing when Firefox was upgraded automatically. It is recommended that if you install the Selenium IDE and use it properly, when Firefox is upgrading, you should be aware that the upgraded version is appropriate for the current version of the Selenium IDE plugin. Do not upgrade if not appropriate, or a weird problem will be a painful problem-solving process. However, if you upgrade Firefox and found that the Selenium IDE can not use or appear before the upgrade will not be able to test, then you need to locate the problem is probably due to the upgrade of the Firefox version of the reason.

Many of the problems that often occur with the Selenium IDE are due to the Firefox version issue. So the installation of the Selenium IDE plugin is here.
