How to install FireFox15 on Ubuntu

The test version of FireFox15 has been released for a long time. As a browser we use every day, it is really too good to try it. Although the test version may be unstable or has some other problems, however, as a software on the system, we have been a trusted developer for a long time, so we can use it with confidence. We can delete it and install it back to the previous version at most. However, I have never encountered any problems since I used browsers of various test versions. Opera I have been using OperaNext, and FireFox has been releasing test versions.

It has been a long time since the test version of FireFox 15 was released. As a browser we use every day, it is really a great deal to try it.

We can delete it and install it back to the previous version at most. However, I have never encountered any problems since I used browsers of various test versions.

Currently, Canonical (Ubuntu parent company) does not support FireFox 15 In Ubuntu. Canonical is expected to be added at the end of this month. What should we do now to install FireFox 15 in Ubuntu? Next, let's talk about how to install the test version FireFox 15 on Ubuntu.

Firefox 15 can be installed on Ubuntu 12.04 LTS, Ubuntu 11.10, Ubuntu 11.04, and Ubuntu 10.04 LTS.

FireFox 15 and 14 have the following obvious changes:

• Native support for PDF files
• Support for SPDY V3 network protocol
• Optimized WebGL support (including compressing textures)
• Memory usage Optimization

Before installation, you must note that this installation will replace your original FireFox with the 15 test version, and your Chinese FireFox with the English FireFox.

Step 1: add the Firefox 15.0 Library

If you are one of the four Ubuntu versions listed above, open a terminal window and type the following command:

Sudo add-apt-repository ppa: mozillateam/firefox-next

Enter the command, press enter, enter your administrator password, and press enter again. Then, follow the prompts to continue the press enter, and wait for the command prompt to appear.

Okay. Do not close the terminal window. Let's proceed to the next step.

Step 2: Install Ubuntu 15

Enter the following command in the terminal window and press Enter:

Sudo apt-get update & sudo apt-get install-y firefox

Well, if you haven't installed and downloaded the software with Ubuntu One at the same time (if you just downloaded and installed the software with Ubuntu One background, it will prompt you that the resources are temporarily unavailable, whether other processes are in use or not. You only need to wait for your Ubuntu One to complete its work ), then you will see that your terminal window is rolling the information quickly (this scene should be a scene that everyone like). You just need to wait and stay online. After a while, your installation will be completed, and your original FireFox will be replaced with FireFox 15.

When FireFox 15 becomes the official version, it will be automatically upgraded in the background. You only need to ensure that it is frequently used.
