How would I sign a firefox addon that a developer no longer has up on the addon page but I saved it ?


Recommended Posts

You'd have to submit it to Mozilla, but they'll only allow that if the original license allowed for you to do so.

So how do I find the original license holder ? So I can ask if it is ok ?

Someone already did it with the addon but it doesn't work right. The old one works great after manually installing it.

The alternative is compile firefox yourself and disable that sodding extension signing rubbish.

 

That's a horrible idea, up there with not using any AV or firewall on a computer 

The proper solution is to find a maintained extension that does the same thing, there is always an alternative

It's not even remotely related to not using a firewall or AV.

If I want to load an extension or make my own and use it, I damn well will, I couldn't give a ###### what mozilla try to do to stop me, you can't even compare someone writing an extension for a web browser and the browser having ###### unwanted 'you cant use this' protection against someone not using anti-virus software or a firewall to stop viruses/trojans/dodgy network traffic. Not even similar.

You know you don't have to pay to have your addons signed right? Simply uploading them to addons.mozilla.org results in them getting signed.

I have no idea why anybody would be upset about addon signing.

It's not about cost, why the heck should I have to upload what I've written to mozilla for something that is not going to be released just for them to 'inspect it'? That's like saying games companies should give away their games to motherboard manufacturers so they can 'inspect how it runs' on their motherboards and certify it.

unpack the extension, update the manifest file, zip as xpi, submit for signing, get a link to the extension and use it for yourself. Worst case scenario: extension is rejected due to coding issues and you have to update the code.

Then sign it yourself, Mozilla have said multiple time they aren't going to be the only people who can sign addons.

And game devs do give free copies of their games to hardware companies to see how it runs, it's great marketing for both of them.

But doesn't that defeat the purpose of signed addons if you can just sign it yourself.

No? The whole point of code signing is so that you know the file is unchanged from the author.

Anybody can take an addon and sign it, but they can't make it appear to be from the original author.

Go and read the mozilla post on the issue, you cannot sign them yourself, they MUST be uploaded to mozilla and have them approve and sign them
Edit: Here you go; https://blog.mozilla.org/addons/2015/02/10/extension-signing-safer-experience/

"Extension files that aren’t hosted on AMO will have to be submitted to AMO for signing. Developers will need to create accounts and a listing for their extension, which will not be public."

Why not use the Firefox Developer Edition in this case?

because developer with e10 is crap (slow and constant crashes with flash). It's better to sign for your personal use the extension and be done with it.

Well, as far as I know only Nightly and the Developer Edition (Aurora too?) has an override for the signing enforcement.

yes. I still think it's easier to submit the extension by yourself and get a signed version for your personal use (as long as you don't have to modify code to go through the automatic signing process) if you want to keep using a "stable" firefox version

    • U.S. partially reverses Anthropic AI ban for Mythos but keeps Fable 5 off the market by Karthik Mudaliar Anthropic says that the U.S. government has finally allowed it to restore Claude Mythos 5. But of course, there's a catch. The rollout is again for a limited set of U.S. organizations that operate and defend critical infrastructure. The company announced this in a post on X (formerly Twitter). This does not mean that Anthropic's latest frontier models are back to normal availability. Fable 5, which was a tuned version of Mythos 5 for public release, remains unavailable. Anthropic said that it is still working with the government to expand Mythos 5 access and make Fable 5 available again, but there's no timeline. Reports from Bloomberg and Reuters say that this decision actually came through a letter from the U.S. Commerce Department. According to Reuters, this would allow more than 100 companies and institutions access to Mythos 5. Reuters also reported that Commerce Secretary Howard Lutnick’s letter removes the need for export licenses for approved companies’ non-US citizen employees, as well as Anthropic’s own non-US citizen employees, while restrictions remain for organizations outside the approved list. Anthropic isn't alone with this kind of controlled rollout. OpenAI's newest model family, GPT 5.6, was announced just yesterday, but isn't available for everyone yet. In its announcement, OpenAI also said that access to these models is initially limited to a select group of trusted partners and organizations, with broader access planned later this year. Both of these cases show that frontier AI launches are no longer just ordinary product releases and more like slow and vetted deployments shaped heavily by the U.S. government.

    • Microsoft Weekly: 5 years of Windows 11, more support for Windows 10, and expensive Xbox by Taras Buria This week's news recap is here, with Microsoft giving Windows 10 one more year of support, Windows 11 getting new taskbar settings in preview updates, Steam Machine prices, higher XBOX prices, and many more. Quick links: Windows 10 and 11 Windows Insider Program Updates are available Reviews are in Gaming news Great deals to check Windows 11 and Windows 10 Here, we talk about everything happening around Microsoft's latest operating system in the Stable channel and preview builds: new features, removed features, controversies, bugs, interesting findings, and more. And, of course, you may find a word or two about older versions. On June 24, 2026, Windows 11 turned five. The controversial operating system was released half a decade ago, and during these years, it received a fair share of criticism (such as poor Windows Search and its web results), which Microsoft is now actively addressing with regular preview updates that deliver missing, long-requested features. With Windows 12 nowhere to be seen on the horizon, it will be interesting to see if Windows 11 can stay on the market for as long as Windows 10 did. Speaking of Windows 10 and staying on the market, this week, Microsoft quietly prolonged the Extended Security Updates program for Windows 10, allowing users to get one more year of security updates if they do not want or cannot upgrade to Windows 11. Finally, Microsoft released this month's non-security update for Windows 11. KB5095093 arrived with a traditionally long list of new features, including point-in-time restore, new Windows Update settings, quieter Windows Widgets, new accessibility features, File Explorer updates and performance improvements, and more. Windows Insider Program Here is what Microsoft released for Windows Insiders this week: Builds Canary Channel Build 29617.1000 and build 28120.2374 These builds bring new accessibility features, new Windows Update controls, audio improvements, and more. Dev Channel Build 26300.8758 This build includes redesigned taskbar settings, File Explorer improvements, and more. Beta Channel Build 26220.8754 and build 28020.2366 This small update fixes the OneDrive bug in File Explorer, tweaks system sounds in dark mode, and more. Updates are available This section covers software, firmware, and other notable updates (released and coming soon) delivering new features, security fixes, improvements, patches, and more from Microsoft and third parties. If you use AI-powered browsing history search in Microsoft Edge, the company has bad news. A new update on the Microsoft 365 Roadmap revealed that Microsoft is discontinuing the feature. Despite using on-device models for natural search, some users found it creepy, claiming that Microsoft lacks trust in features like this. While the ability to find pages without using 100% precise words may sound cool, customers argued that it was nothing but another feature to bloat the browser with more AI. Good riddance? PowerToys received several updates this week. For one, Microsoft released version 0.100.1 with several improvements and bug fixes for the recently arrived version 0.100. A couple of days later, Microsoft dropped another update, this time fixing memory leaks in Command Palette Dock. In addition, the company is working on a new module that will make it easier to switch between windows within one application using the Alt + ` shortcut. The new module should make it to the stable release somewhere soon. Here are other updates and releases you may find interesting: New Ventoy update adds Windows 11's mandatory update support and more Microsoft updates Visual Studio Code with chat cost tracking and multi-agent chats Microsoft is building an AI datacenter that "uses less water than a fast food restaurant" Microsoft adds new AI study and teaching tools for free to Microsoft 365 Education Researchers claim Microsoft's quantum breakthrough is flawed by basic Python errors Microsoft is bringing a much-needed Recap app to Teams Microsoft's fast coding model, MAI-Code-1-Flash, comes to Copilot Business and Enterprise Here are the latest drivers and firmware updates released this week: AMD Radeon Software 26.6.2 with FSR 4.1 support for RDNA 3 graphics card. However, the driver contained a bug, which prevented installations on Windows 10 PCs. AMD fixed that with a quick hotfix update. Reviews are in Here is the hardware and software we reviewed this week This week, Steven Parker published several reviews. He shared his experience with the Creative Sound Blaster AE-X PCIe, a high-quality sound card with a headphone amp, low-latency communications, great build quality, and DSD256. However, it is on the pricier side of the spectrum, and it lacks EMI shielding. Check out the full review here. The second review is about the TerraMaster F4-425 Pro, an octa-core Intel NAS with a stand-out feature: built-in AI (OpenClaw). We also published a few Hands On reviews, which you can view below: We check out the SKG PS700 Neck Massager SKG Hand Massager with Heat OS500 hands on Hands-on with BOOX Tappy: cute little reading accessory Hands on with the ProtoArc EM25 affordable ergonomic mouse On the gaming side Learn about upcoming game releases, Xbox rumors, new hardware, software updates, freebies, deals, discounts, and more. If you plan to purchase a new Xbox, it's time to act now. This week, Microsoft announced yet another Xbox price increase. Starting August 1, 2026, all Xbox Series X|S models with 512 GB of storage will cost $100 more. As for the 1TB models, they are going up in price by a whopping $150. Finally, Microsoft is discontinuing the 2TB Xbox Series X. To make up for that, Microsoft announced a few programs to make its consoles more accessible. Those include BNPL, interest-free financing, pre-owned consoles, certified refurbished consoles, and more. Valve also shared some not-so-welcome news. The company has finally announced prices of the upcoming Steam Machine console, and if you plan to buy one, get ready to spend a whopping $1,049 on the 512GB configuration. The Steam Machine is now available for preorder, with shipments scheduled for June 29, 2026. Grand Theft Auto VI also received its official price tag. Rockstar Games announced that the long-anticipated game will launch at $79.99 for the base edition and $99.99 for the ultimate edition. The latter includes an exclusive collection of premium vehicles, weapons, apparel, and action threaded across all aspects of Jason and Lucia’s story." Those who preorder the game will get extra bonuses, including a Vintage Vice City Pack of cosmetic items as well as a free month of GTA+. NVIDIA announced new games for its GeForce NOW streaming service. Those include Dark Scrolls, SAND: Raiders of Sophie, Deer & Boy, EMPULSE, and more. Steam is running its annual Summer Sale, during which you can purchase plenty of various games with big discounts. It runs until July 9, so in case you missed it, you can still get some games at a lower price. Also, you can get two games for free in the Epic Games Store, plus more deals are available in this week's Weekend PC Game Deals issue.

    • Text extractor hasn't been working great on 0.99.1 but I am now updating to this version, hopefully it's better!
    • Yet you did exactly what they wanted you to do - is it better now without "Europrats"? BTW, UK had joined EU (EEC back then) and was one of the leading member states, it never joined Schengen Zone though 😉
