Why do you want to install an older browser (I assume you mean an older version of Firefox, but I'm not sure)? Please be more specific about the problem that needs to be solved.

Oh, I just realized this was supplementing your main question here: https://support.mozilla.org/en-US/que.../973658.

As already posted, best is always to identify and solve problems instead of downgrading to older Firefox versions.


Only the Firefox 17 ESR and Firefox 24 ESR versions in the future can be considered as older Firefox versions as long as they are supported with security updates.

All older Firefox versions have security issues that make you vulnerable to malicious websites.


If websites only work with older Firefox versions and not with the current release then best is to use a portable Firefox version only for those websites and use the current release for all other websites to be protected as good as possible.
The portable version comes with its own profile folder and doesn't interfere with the currently installed release version.
