I can't seem to update to the latest version of Firefox.

Steps on macOS 15.2: 1. In previous version of Firefox, get dialog to update to current version of Firefox 2. Click Restart to update Firefox. 3. Enter admin user name and password to allow Firefox to install a helper 4. Got a request to let Firefox access my devices. My devices are not Firefox's business, so I replied Don't allow. Note: 3 and 4 may have been swapped.

Expected result: Get a dialog that Mozilla corp has installed something; Firefox relaunches with the new version

Actual result: Get a dialog that Mozilla corp has installed something

Attempted workaround:

5. Click Firefox icon in the dock

Expected result: Firefox launches

Actual result: Get dialog asking me to enter admin user name and password to allow Firefox to install a helper.

6. I do so.

Expected result: Get a dialog that Mozilla corp has installed something; Firefox relaunches with the new version

Actual result: Get a dialog that Mozilla corp has installed something

Attempted workaround:

7. Click Firefox icon in the dock

And I get a strange feeling of deja vu as the process repeats and I am unable to launch Firefox.

If I look at the macOS console and filter on Mozilla, I notice these two messages from org.mozilla.updater:

1. Server doesn't exist or doesn't provide correct selectors.
2. Failed to connect to update server after several retries.

I have no idea how to proceeed.

Each time I download and install updates to Firefox, whatever they are correcting causes the application to not open. I need to delete the Firefox, download the file and reinstall it.

My laptop is a new HP with an Intel(R) Core(TM) Ultra 7 155H 1.40 GHz processor with 16.0 GB (15.4 GB usable) ram. It is a 64-bit operating system, x64-based processor. I am running Windows 11 currently.

Do not understand the problem. I have Firefox on my older laptop (over 10 years old) with a i3 processor and do not have these issues.

I have had to reinstall Firefox several time on the new machine and am frustrated with the problem.

Please have a good recommendation. I will refrain from updating Firefox.

If you select No to the UAC prompt when updating Firefox via Installer, it will install Firefox to "AppData\Local\Mozilla Firefox" without telling you, instead of overwriting the copy in Program Files or erroring out. Additionally it will create a new Profile and set this new Profile as the Default Profile without telling you. Lastly, it'll remove an existing Pinned shortcut on the Taskbar.

So you've now got 2 copies of Firefox installed, one of which you're not told anything about and an additional Firefox Profile with no indication that this happened nor any instructions on how to undo this nor how to change the default Profile.
