is there a danger to keeping unused browsers (not updated) on my PC

There are some users who keep other browsers on their PC in addition to Firefox - i.e., chrome, etc - that are unused and not updated. for most, when they do launch the browser, it will update, but is there a security vulnerability/risk it keeping an unused, unupdated browser on a machine (i.e. plugins, add-ons,etc)? I say remove it if not needed, but our admin says there is no issue with having these on the system since they will update if they are ever used.

thanks!

Hi, no danger at all - as long as one of them isn't your default browser, and if you do want to use them, you make sure they are up to date first.

I currently have 7 other browsers installed for comparison and testing purposes!

If your question is resolved by this or another answer, please take a minute to let us know. Thank you!

I think you can imagine a scenario where a command line is executed on the PC that launches content X in program Y, or a reusable component of program Y is called or instantiated by program Z, to exploit a known vulnerability in program Y. That may occur too quickly for an updater to protect the system.
