What will change when I install Firefox ESR?

Posted

Hello. I want to install Firefox ESR on top of my current installation, but what will change when I do so? What is different in ESR?

See, I have downgraded to FF 40 due to extension/add-on problems with FF 42, but I don't want an unsafe/unstable browser. ESR was recommended, but I'm confused about it. Will all my bookmarks, themes, add-ons, etc. remain the same? Is there a different updating schedule, and how does it work? I really need some help here.

Thank you!

It's a good idea to backup your profile first, but IMO you probably won't have any issues when reverting to Firefox 38 ESR. I did that back in June - switching to Firefox ESR 38.2 from Firefox 40.0. There shouldn't be any issues with add-ons, unless a security fix would cause a problem with an add-on.

Overall the ESR version is the same as the Firefox 38 Release version, but with the security fixes that came in subsequent releases. No new or changed features that may have been in the Firefox 39 thru the latest Releases, just security updates. The schedule is the same for Release and ESR versions. https://wiki.mozilla.org/RapidRelease/Calendar

Hi

Firefox Extended Support Release is designed for organisations that require a slower update model to for testing and stability purposes. More information about Firefox ESR can be found here.

If you are going to move to this version of Firefox, I recommend you take a backup of your Firefox profile, that you can then install in Firefox ESR. You can read how to do this here.

Personally I would not recommend using this for the reasons you mention. I would suggest you contact the provider of the add-on you wish to use and see if you can find out when an updated version may become available.

I hope this helps, but if not please come back here and we can look into a different solution for you.
