In this post, we will explain how to install / upgrade firefox on Ubuntu 14.04 LTS Desktop. After installation of Ubuntu 14.04 LTS in my laptop, we upgraded the firefox to version 29. Now at the time of writing this post, firefox stable verion 43 is available.
There is no change in command line, as we have written previously in our post on “Install firefox 29 in Ubuntu 14.04 LTS (Trusty Tahr)“. A one more step we will do that’s it.

Simply run the below given command line. It will either install or upgrade the existing firefox on your system. Please note that close the firefox while running these commands.

After successful command completion, what next?
Open the firefox and visit this firefox URL – https://www.mozilla.org/en-US/firefox/new/ .You will see one ‘Refresh button’. Click on it. It will check and fix the issue in firefox if it exists. [We forgot to take screnshoot]
