- How to install Flash player on Ubuntu? 5 answers
The firefox on my ubuntu requires me to update Flash plugin and follow the link I get to the page which ask me to download the latest Firefox package. I download the tar.gz and unzip it. It is the new version, but it is in an independent folder and if I want to use it, I need to open the folder and click on the Firefox executable.
How can I replace the old version of firefox on my ubuntu with the newly-downloaded?
I checked the old version:
I'm not very familiar with linux system. But what is /usr/bin/firefox? is it a symbolic link which link to the Firefox executable in /usr/lib/firefox? how can I replace it with the new version?
thanks!

First of all, you may run into a false message from a webpage asking you to update flash when running linux because, although linux flash still receives security updates from adobe, our flashplayer is stuck on version 11 or 12 point something whereas all apple and windows users are using version 18 or 19.
You can safely ignore these messages and some of these messages have actually been linked to malware in the past so be very careful my friend on what you click on and trust nobody.
To keep your flashplugin updated, install the flashplugin downloader from apt-get and it will update itself. Open a terminal and run the following commands:
To update firefox, run the following commands:
Don't forget to restart firefox.
If you would like to install firefox nightly, please let me know and I will provide instructions on how to do so.
