Support and Help

Very old computer
Mint ???
Firefox 113… 64bit

Hiho all

I have the same problem, I was going to post a new question, but can’t find where to make this !

I turn on my computer once a week, Saturday, to do my accounts and check bank payments, but I think this is now un-wise to do stuff being, I quote:
“One or more installed add-ons cannot be verified and have been disabled”

japfin above may have the same worries ?

Moved to a separate topic. Your version is different and your error message is different, so “the same problem” may-or-may-not be accurate.

Sorry you got lost. The instructions for this site are within the “Start here” link on the front page…

No supported release of Ubuntu uses Firefox version 113; it was used by bionic (18.04) last (at EOSS) though 18.04 with ESM is using Firefox 136.0.1-1 (or 128.8.0esr-1) now.

You also mention Mint?? Why? It’s not a supported Ubuntu system, and is supported elsewhere.

What are you running? (If you read here you’ll see only Ubuntu and official flavors are on-topic)

ubuntu jammy here - firefox literally disabled all addons installed from official mozilla addons website - “couldn’t verify signatures” even though about:config flag “require signatures” is set to false. Either mozilla using backdoor into my browser…

From mozilla blog " On 14 March a root certificate (the resource used to prove an add-on was approved by Mozilla) will expire, meaning Firefox users on versions older than 128 (or ESR 115) will not be able to use their add-ons. We want developers to be aware of this in case some of your users are on older versions of Firefox that may be impacted."

Could you apt-cache policy firefox please?

Thanks @vovaout , though I doubt that is the issue (even if technically is the reason for the problem), as a quick CLI scan of firefox packages on my system (including ESM releases) and the oldest deb package I see available is 136.0+build3-0ubuntu0.20.04.1 for focal…

The closest I saw to the version provided in the original post was a 18.04/bionic system that is both unsupported on this site now (supported via Canonical & ESM) and hadn’t been updated to use the newer updates available for 18.04/bionic as per Security Notice for that release (if it had the packages would have matched those in my prior comment)

@vovaout to put these questions about what you’re running to rest, please provide the output of these two commands:

  1. lsb_release -a
  2. apt-cache policy firefox
