Extensions became disabled because they "couldnot be verified."

I am truly disappointed in Firefox now. First, I kept constantly getting messages that plug-ins stopped working, which kept freezing my browser and/or computer and forcing reboots. Now the Yahoo Toolbar that I relied so heavily on for links to popular places like eBay and Facebook is gone, and there’s some BS about needing to have the plug-in “signed” or update to the latest version before Firefox will accept it. So I tried re-downloading the most recent version, only to have Firefox reject it completely, just because it does not meet Firefox’s new rules. Is Firefox trying to monopolize plug-ins now, forcing us to use only the ones created or accepted by Firefox? I am definitely NOT happy. This is forcing me to look for a new browser that won’t block plug-ins that -I- want to use. While I can certainly understand the need for strong internet security, this goes way beyond all reason and has created too many frustrating issues. You are going to lose a LOT of users over this. I suggest you figure out something better FAST. Even when Firefox gave me the option to “Allow” the Yahoo Toolbar, as soon as I tried to download it, Firefox blocked it and said that it was “not allowed.” Do we no longer have control over what we do and do not want on our own computers?

I am having the same issue, been using Firefox for years, always satisfied…sorry but if the only solution is to contact every developer and ask them for a digitally signed version…I have better things to do, especially when it has blocked Avast Antivirus amongst others, that I know for a fact are from a trusted source. Why should it be the users responsibility to fix what was a perfectly running browser, after spending a few hours already trying to figure out what the problem was in the first place.
If the Extensions were working without a problem in the previous version, then it should be able to continue using them in the next version without a problem, or at least be given the option to choose whether to continue using them…I had Firefox on automatic updates and am now looking how to go back to a previous version…which is just taking up even more time.

I have been using Firefox for over 15 years, have tons of bookmarks here, but always use MyYahoo as my main page and had installed the Yahoo Toolbar. I upgraded Firefox and you JERKS have taken away my Yahoo Toolbar, where I have kept thousands of bookmarks over the last 15 years…now I am supposed to go to my MyYahoo page every time I want a bookmark? I had my toolbar set up with all my favorite things that I use…AND YOU DISABLED IT…WITHOUT MY PERMISSION! I am supposed to reinstall it at my own risk and only if I am am a qualified engineer??? Sleazy move, Firefox. write my email and give me back my toolbar on Monday, or I go looking for a new browser. You have lost me as a fan…

Seems like this is a fad anymore like with MicroSucks and win10 and how it’s going to take your system over. Now

mozilla is trying to be like big brother. To take care of that I’ve been well ahead of that with Mint a Linux distro for years.

But… Being that FF is the default browser with Mint presents a small problem. Small problem indeed. With that I went

with Pale Moon. Pale Moon being like what ff used to be. Light, fast and you have control. Until these Subaru drivers stop
trying to tell you they like Dad and Mom knows what’s better for you and what add-ons you should and not use. It’s not

going to end. MOZILLA. LEAVE US ALONE!

I have the same problem since I updated to Firefox 43. I’ve used Firefox since several years ago, but now I’m seriously thinking in change to Internet Explorer or Chrome - which I wouldn’t be very happy with - . I like the Yahoo Toolbar, because there I access quickly to my favorite sites, like Twitter, Facebook, my mail, etc, but every time I try to install it, Firefox disables it. Yahoo Toolbar is verified, then is incomprehensible why Firefox is doing this. Very disappointing!

Andreas Wagner, i am sorry to be honest but this is complete distaster. OK, i am not saying signing is completely bad, if you provide some reasonable way for addons to get signed IN NORMAL TIMEFRAME. I have requested preliminary review in November, and extension is until now in queve, moved from 100 to about 50. In chrome, getting signed is just much more simple and straightforward. Lot of my customers depend on the disabled extension and all i can say them now is ‘sorry’…

I am forced now to look for possible cracks of firefox to remove this BS, so i can recommend my customers crack firefox, downgrade it or just go to chrome.

I recommend you contact Yahoo directly. They have not submitted a version to us so we could sign it.

We know about the backlog. We are working actively to reduce it, we even hired more people to work on it. It just takes a bit more time. What is your add-on?

This is the extension in question: http://ow.ly/Wdx3b. What i am also worried is, that after that long wait, there will be eventually some little problem to fix, which will result in need of waiting to wait same queue once again…

Cool Previews worked great yesterday and is not supported as of today. It is one of the best add-ons, I used it all of the time, It’s disappointing that great add-ons get taken away and yet worthless ones are always available

Sorry, but that is not an acceptable answer to me. Why have I to do your work? Until Firefox 42, Yahoo Toolbar was verified ( not for me ), but now, suddenly, is not? It think this a total disrespect with Firefox users.

CoolPreviews was discontinued quite some time ago by their developers, see their website.

We have already contacted them several times. It is up to them to take action and submit a new version.

One way to enable the extension is to disable the signature check in FF43 by toggling the xpinstall.signatures.required setting in about:config.

Another is to get the users to download and install FF ESR via https://www.mozilla.org/en-US/firefox/organizations/all/
FF ESR (Extended Support Release) is FF38 but it receives all the latest security updates at the same time as the main release branch of Firefox, and it doesnt check for signatures on extensions. Its version number wont be bumped up for about 6 months or so.

I follow what user  jafo1966 says: "Ok, I get the new update requires the add-ons to be verified, but what is the deal when an add-on directly from Firefox's own add-on site is marked as signed and verified, but continues to be disabled and deleted every time I restart Firefox???? The current one in question is the Yahoo Toolbar." So, I insist in my complain, because is exactly my case. I want  Firefox as my  browser, I like it, but with all these obstacles, it seems Mozilla doesn't want us anymore.

You say it was discontinued some time ago and yet it was working on my computer on 12/21 and on 12/22 it is just gone. So for something discontinued why did I still have it up through yesterday.

Discontinued does not mean broken.

This screen shot shows that the Yahoo toolbar IS signed for Firefox Add-ons. If it wasn’t why is it in the add-on store??? And why does it say its signed??? Let’s get it together folks…don’t blame Yahoo for something you screwed up in your updates, or remove the Yahoo toolbar from your add-on store til it is updated to your ‘standards’.

Yahoo is modifying add-on files silently based on various factors like cookies and server responses. If and when add-on files are modified, the signature is broken as Firefox can no longer verify their integrity. It is up to Yahoo to change to code to not manipulate add-on files.

Correct me if I am wrong, but don’t you retain a singular download link for your verified add-ons? Yahoo can change all the things they want on a toolbar found on their own website, but your add-on store download does not link to them. This means the most recent one in your store, which is signed and verified by you isn’t tampered with by Yahoo…or it shouldn’t be.

Any download from the Firefox Add-on store should be a separate and distinct link from any other download for that same item…for example, I can expect that if I went to the website for Ad-Block Pro, and downloaded it from there, that it could be rejected by Firefox for not being digitally signed. By the same token though, if I download it directly thru your add-on store, I expect it to be stable and to work fine within Firefox.

Again, if you cannot maintain a secure add-on from your own site, then it needs to be removed from your site til you can keep a stable download in place.

I think you misunderstood.

There is code inside the add-on that modifies at least the install.rdf inside the add-on.
