6, Ubuntu16.04 manual installation of any version of Firefox

After the installation of this system, the Firefox version is 51.0.1 (64-bit).

If you want to manually download the latest version of Firefox in Ubuntu, go to its download page. With it you will be able to get to the latest version and install it.

If you want to install other versions of Firefox from the initial version, visit this page. In this you will see each version starting from 0.8.

After downloading the version you want, switch to the download folder in the home directory, as most of the Ubuntu files are downloaded here.

Configure Firefox

Since most Firefox download files are saved in. tar and. bz2 formats, you must extract the files from these compressed packages. There are many ways to extract files in Ubuntu.

For example, I use the command below. It is easy to extract files from. tar and. bz2.

1. 1. Tar -xvf Firefox*. Tar. bz2

After unpacking, a new Firefox file will appear in the download folder. This includes all of the Firefox files and executable files.

Since we do not want to delete the currently installed Firefox, we must create a separate folder for each version of Firefox. Therefore, for Firefox version 30, use the following command to create a folder in the/opt directory that contains the new Firefox content.

1. 1. sudo mv Firefox//opt/firefox55

Now, all the files contained in the/opt/firefox55/ directory are version 30.

Create a new Firefox executable symbolic link

By default, Firefox's executable file is under this path:/user/bin/firefox. What we want to do is create a backup temporarily so that we can use our custom installed executable file.

To do this, run the following command.

1. 1. sudo mv /usr/bin/firefox /usr/bin/Firefox - old

Now that we have moved the Firefox executable from its default location, we must link the default location to our new custom installation file. To do this, run the following command to create a symbolic link for our version 55.

1. 1. sudo ln -s /opt/firefox55/firefox /usr/bin /Firefox

This setting is complete, and our custom-installed Firefox is the default for Ubuntu. Every time you start Firefox, it will load a new executable file with the new link.

9、Ubuntu16.04安装chrome驱动方法
If you want to run the Web automation use case only with IE or chrome, you need to install the appropriate browser driver first. Note that different versions of the browser also correspond to different versions of the driver, http://chromedriver.storage.googleapis.com/index.html select the corresponding version to install.
My browser version is: Version 62.0.3202.75 (official version) (64-bit), I downloaded the driver for V2.33.
