Update Quantum is a complete mess

This Firefox version is awful. I’ts probably pre-5G crap. Ad blockers are not working and I am unable to add my json bookmarks file. I decided to get rid of it and revert to an older version. The only available one wasn’t worth the effort. I then reinstalled the latest version again and still unable to add my bookmarks or even download ad blockers. Is this something to do with invading everyone’s privacy? Is it because I use an actual desktop and not a bloody phone? I am really fed up.
I’m using epiphany till this is sorted. Wanting privacy does not mean I have to do my washing in google.

See https://blog.mozilla.org/addons/2019/05/04/update-regarding-add-ons-in-firefox/ for details on why this is an issue. The fix is being rolled out right now, sorry for the inconvenience in the meantime.

It’s not your fault, I know, sorry for rant. I have everything just hunky dory then suddenly it’s like the 90’s

Is 66.0.4 beta from a particular repository?

66.0.4 is not a beta and will be rolled out like a normal update. If you’re not on the release or ESR version it may take a little longer, yet.

I’m on 66.0.3-build-0ubuntu0 16.04.1. using Synaptic on a Desktop, can you suggest a repository?

Ah, sadly you’ll have to wait for the Ubuntu package maintainers to release the fix. The only reliable way to get it right now is to use the binary distributed by Mozilla at https://www.mozilla.org/en-US/firefox/new/ - I am however not sure how well that will mesh with the version you have from the ubuntu ppa, plus it’s harder to properly integrate.

I am happy again. Also all my bookmarks and logins are intact (actually this is miraculous as I had removed firefox ).
Here is what i found, I added the repository to Synaptic and the update appeared in the list, easy no fuss, all good.
Remember to do the sudo update if doing it manually and/or refresh Synaptic sources after adding repository:
