Note: This is not duplicate of How do I downgrade Firefox v. 57 to v. 56?.
I have installed firefox using sudo apt-get install firefox
Right now it is installing version 63.0 which has some issue with selenium webDriver.
So I want to downgrade because this selenium webDriver is working fine with version 57.0.4.
I tried sudo apt-get install firefox=57.0.4+build1-0ubuntu0.16.04.1 which is not working and saying that:
E: Version '57.0.4+build1-0ubuntu0.16.04.1' for 'firefox' was not found
The strange thing is that I am able to install version 45 using sudo apt install firefox=45.0.2+build1-0ubuntu1
I have taken the syntax from Here.
Any help will be highly appreciated!
