Firefox ESR?

As a non-enterprise user, should I install the regular version of Firefox or the ESR version? As far as I know, the ESR will still remain on the current build but the security updates will still be maintained in the ESR version.

I am afraid if Firefox gets a major update, then things might break. With the ESR, I can be sure that an update has been tested throughly before pushing them out.

Will the ESR version still be updated with security updates in a timely manner?

I’m more concerned with these major releases.

With the ESR version of Firefox, whenever there is a new update, will I need to download and install it manually or will Firefox automatically update?

For example, let’s say Firefox v78.12.0 (ESR) comes out, will Firefox automatically be updated with that version or does it need to be downloaded and installed manually?

Let me just ask my questions in a more organized way below for Firefox ESR:

1. Will new major releases be automatically updated by Firefox ESR or will it need to be manually downloaded and installed?

2. As for security related updates, will I receive those automatically? If yes, what would be the time cycle for only the security related updates?

3. And what is the Maintenance Service used for? What does that do?

1. Tor gets automatic updates by default, security and new versions. It will be the same for the ESR browser. See screenshot.

2. No trace of maintenance service (custom install not available) during the install: Windows and Linux.

3. In regular version it is never installed here. You have to check if custom install shows up.

Like I said above, updates are not frequent. The alpha release (10.5a6) was updated on June 5th (see log). Both regular (10.0.17) and alpha follows the ESR update pattern. Previous update was in April for 10.5a15.

This is a quite and stable environment.

Security Vulnerabilities fixed in Firefox ESR 78.11 — Mozilla

Thank you for pointing that out, but I still prefer to use the ESR version.

In the ESR version, will I still get security updates automatically as soon as Mozilla releases them?
