All of my addons are disabled and won't re-enable!

They all say "addon name" could not be verified for use in Nightly and has been disabled. See attachment clipboard00.jpg

If I try to install an addon from the recommended extensions settings (for example "return youtube dislike ") I get a message bubble stating "The Addon downloaded from this site could not be installed because it appears to be corrupt. {OK!}" See attachment clipboard01.jpg

The message above about addons appearing to be corrupt happens if I go to any of my current addon pages and try to redownload them.

Hi there, I'm trying to make a little old machine useful it is an HP mini (Laptop) with an Intel(R) Atom(TM) CPU N455 @ 1.66GHz and 2GB of RAM; it appears the firefox version is too old to install some extensions/add-on like uBlock... I don't want to throw it in the trash; any recommendation please?

Some quite strange questions, which I'm not sure to which category it belongs to, While I use last FF on my main machine, I have another machine that still use firefox 56.0.2 since I like some of the addons there that never been remade/updated to newer FF versions,

It worked fine for years but suddenly all of the addons are disabled no matter what I've tried to do, Using backup, reinstall, about:config and setting xpinstall.signatures.required to false, you name it,

I was wondering if Mozilla pulled the plug on something or if some fixed date for things to expired has arrvied, As well as if there's a way to fix it in the settings/other means?

Some people said that Dev or Nighty edition can actually turn the xpinstall signatures to false while normal FF might have the option but won't actually do it, The problem is that I have no cluse which of their versions is equal to good old 56.0.2, Can anyone tell me?

Thx

itu adalah contoh dari web yang saya mau buka ternyata error. Ngga hanya sekali, beberapa website pemerintah lokal yang mau saya buka terkadang memperingati bahwa websitenya tidak aman (Not Secured).

Apa karna Laptopnya bukan produk lokal? laptop saya ini dari Singapure dan pengaturan awalnya tidak bisa diganti, jadi tidak bisa dibuka website2 lokalnya? karna mendeteksi dan kebacanya IP laptop saya asing?

I can't figure this out. I've been having this issue ever since I deleted my KMspico files after I did a scan using Malware Bytes (it was labelled as dangerous files or whatever so I let the app delete it).

After the restart, I can't use nor reinstall the Discord app along with being unable to download any Extensions, Themes, or Plugins for both Firefox and LibreWolf. It's frustrating as I had to go back to previous browsers, which I didn't want to do. Any help in fixing this is highly appreciated as I really want this fixed.

--- File location is C:\Program Files (x86)\LibreWolf [Same for Firefox]

--- Must I reinstall Windows in order to fix this issue or are there other ways that don't involve reinstalling Windows?

Hi, I recently purchased a new laptop and want to bring over the bookmarks I had from my old laptop. I had copied what I thought was the profile from the old one and copied it into the new laptop - but I'm not sure of the next steps :(.

I'm used to using the extension "Пульт". I guess that means "Remote control". After a recent update, this extension has been removed. I received this message: " The Remote control in Firefox has not been tested, so it has been disabled." I want to restore this application and ask for help.

Hi there, im using a grandfathered firefox due to my old OS (10.10.5) Tonight ( 3/15/25 ) all my extensions (duckduckgo, adblocker plus, badger, etc ) were disabled. how can i enable them again? thank you for your time

Hi, I've been receiving the following rejection message as follows: jino.ru rejected your message to the following email addresses:

postmaster@pop3-server-spam.org The address you sent your message to wasn't found at the destination domain. It might be misspelled or it might not exist. Try to fix the problem by doing one or more of the following:

   Send the message again, but before you do, delete and retype the address. If your email program automatically suggests an address to use, don't select it.
   Clear the recipient AutoComplete cache in your email program by following the steps in this article: Status code 5.1.1. Then resend the message, but before you do, be sure to delete and retype the address.
   Contact the recipient by some other means (by phone, for example) to confirm you're using the right address. Ask them if they've set up an email forwarding rule that could be forwarding your message to an incorrect address.

The sender of the email gets those message. I get them also but I'm also getting the message that they send me. It's only doing it with my outlook account. Why is that? I checked it directly on the Outlook website and everything is OK. I can't understand why this is happening.

I'm finding that firefoxcp isolated web content uses a LOT of memory on my Mac Mini. What can I do about this besides not using Firefox. I like the browser and have been using it since its introduction

1, provide phone support....which i am willing to pay for.

2. fix it -- remove the problem via an update

3. A new computer....and I still get this "Application error: a client-side exception has occurred (see the browser console for more information)." WHY ? Of course, GREAT that Mozilla never has real people to staff tech support.

Hello!

I am not sure if this is a Firefox specific question or one that relates to Windows, but I can't seem to figure out how to turn off the feature of a two-finger swipe either making the webpage jump back, or forward. I haven't been able to find any answers by looking it up on my own, and can't find where to change this feature in either Windows or Firefox settings. Is this a feature that can be turned off?

Any help would be very appreciated!
