If I install Firefox ESR, will I still have access to my "regular" Firefox?

My Outlook accounts are refusing to attach documents to email, and I was advised to install Firefox ESR. But I'd like to only use ESR for those instances when I need to send attachments with Outlook. Is this possible?

Download the full installer. Then during the install, switch to manual and Use a different folder name.

Thanks very much!

You need to use a separate profile for the ESR version to avoid problems.

You can also consider to install a portable (ESR) Firefox version to access websites that do not work with the current Firefox release. The portable version comes with its own profile folder and doesn't interfere with currently installed Firefox versions.

Thanks. I installed ESR, which solved half my problems. One (but not both) of my Outlook accounts will now deign to attach files to email. I'll try the portable version.
