Hello! Yesterday (03/16/2025) I received a message that the ChatZilla add-on to Firefox will be disabled on the next restart of FireFox. The message indicates that the extension could not be "verified".

I am using a VERY old computer for ChatZilla only: Windows XP Firefox 48.0.2 ChatZilla 0.9.92

I don't care about the age and inability to update any of the software, but I need to continue to use ChatZilla on this platform.

I have used ChatZilla on this machine for a very long time and do need to continue. Is there any way that I can make this work without having ChatZilla automatically disabled at the next restart of Firefox?

Firefox says versions earlier than 115.13 will be impacted by the certificate expiration. I've updated to 115.21 My add-ons are still disabled. https://support.mozilla.org/en-US/kb/root-certificate-expiration

It seems many don't know or haven't noticed but merely running an esr branch (rather than a developer edition) will also give you the option to enable add-ons with expired certifications via about:config.

Anyway, the "legit" way isn't working.

Please assist or advise why Firefox seems to be slowing down my system by memory usage. I have a handful (6) of tabs open on 1 browser session and my system started slowing down so I checked my task manager and it shows that I have more than a dozen of Firefox instances open chewing up almost 90% of my memory.

Please assist or advise me on how to tweak my browser to perform better, and not to show ghost instances

Hi,

suddenly, all of add-ons have been disabled.

It is say that is an security problems,..., but all of them?? suddenly??

can you please provide some support/help?

I attach screenshoot with release and evidences disabled.

Tks

Hello there, we are using blue prism version 7.1.1 & having couple of live processes running on Mozilla FireFox which are started failing from today morning, as we browsed on the internet and found that some root certificate upgrade happened at Firefox end which made Blue Prism extension disabled. kindly can you check and help with some interim solution to avoid impact on business.

My firefox browser being hack multiple times, so I dident use it for multiples years... Now I just want to give it an other chance by removing everything that could create trouble. When I get over the setting windows I can read this: Information Your browser is being managed by your organisation.

I don't understand, this is my private computer. How to remove this organisation management???

One specific cache entry always contains a trojan virus everytime I run an anti virus check. I can't say where this cache comes from as it appears even if I don't open a single new website. I delete it but it appears everytime I use the Browser again, even multiple times during one session. It is always the same entry code. Is there a way to block a specific cache entry or at least to discern where it originates?

Is it possible that every single add-on I had has been simultaneously disabled because it is "corrupt" or the sign-on could not be verified? Is it due to my old operating system (El Capitan)? If that's the case, I will have to stop using Firefox on my old iMac and use it on my MacBook Air, a device I really don't like because of the keyboard.

I subscribe to my city's newsletter. It gives quick links "click here" to register for a class, "click here" for information about an upcoming parade. I used to be able to click and get it. Now it tells me It can't find the site OR I might be connected but behind a firewall. There are too many options and too many terms, I don't know what to do, I just want to click links from my city newsletter, and get taken to them. Help???

Hmm. We’re having trouble finding that site.

We can’t connect to the server at vu4mbwlab.cc.rs6.net.

If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)
