Thetechnology for extensions in Firefox is, to a large extent, compatible with the extension API supported by Chromium-based browsers (such as Google Chrome, Microsoft Edge, Opera, Vivaldi). In most cases, extensions written for Chromium-based browsers run in Firefox with just a few changes.
Discover what extensions can do before building your first extension. Learn about the anatomy of an extension and get an overview of the extension development and publication workflow, Firefox style. Explore a little deeper with a comprehensive selection of example extensions that you can run right in Firefox.
Get detailed information on the concept that underpin extensions from an overview of the JavaScript API, through content scripts, match patterns, working with files, internationalization, and content security policy, to more advanced subjects such as native messaging, using the devtools APIs, and native manifests.
From patterns you'll regularly use such as work with the Tabs API and adding a button to the toolbar to more advanced topics such as intercepting HTTP requests and working with contextual identities, you'll find a range of tutorials to get you started.
Get comprehensive details about the methods, properties, types, and events for all the JavaScript APIs. There is also detailed information about the compatibility of each API with the major browsers. Most reference pages also include coding examples and links to the extension examples that use the API.
MDN web docs will onboard you to the basics. With tutorials from simple user interface changes to complex event handling, MDN covers the structure and API behind extensions. Once you know the fundamentals, come back here to learn how Firefox takes extension development to the next level.
Hi - I have been using Kaspersky Password Manager for many months, and it has great autofill capability for many browsers. It has been working great with Firefox, but as of a month or 2 ago... it suddenly stopped working.I checked my extensions and it's no longer there. When I search for Kaspersky extensions... I don't see it anymore. Only "Kaspersky Protection", etc.Does anybody know if the extension isn't available for the current Windows version of Firefox?Of COURSE it works great in the (C-Word... CHROME!) Yuk.Thanks.
The UUID after moz-extension is unique per Firefox profile. I tried searching for scripts/uninterrupt.js which found -extension-manifests-dataset/blob/89e366efc48a4eb644bf7d37ba1f916e65297f2a/manifests/mjopeoajpfbfbflifdnhpjnijpiefael.json. Looks like a Chrome extension, but maybe there is a Firefox version somewhere.
At this time, HubSpot does not plan to build a Firefox plugin for HubSpot Sales because we are not able to bring a comparable experience to Firefox that we have for Gmail and Outlook. As we evaluate other enabling technologies like Google add-ons, we will revisit this idea in the future but for now we are not planning to build a Firefox plugin.
Thank you for your question. The Hubspot Sales extension only works with Google Chrome or Outlook, so there isn't currently a way to resolve the issue using Firefox. If you do want to use the extension, my best suggestion is to download Google Chrome and install the Hubspot Sales extension. You can keep using Firefox for browsing the web, and reserve Google Chrome for the sole purpose of Hubspot Sales.
How could you not have a FireFox extension? I just switched over to FireFox because Chrome is a memory hog on my Mac and discovered that HubSpot doesn't work with it. I use the hubSpot extension with my business email, which I'm in all the time. It doesn't make sense to switch to another browser to go to other sites when I'm already in one for the email. It would still be using up memory and defeating the purpose. Please develop a FireFox extension. thank you.
That is quite a bit to ask users to use a different browser to have access to hubspot's resources. I have heard there are other companies that allow for the same email tracking without having to use a specific browser. Being a program for sales, one would think that Hubspot would be good at catering to their clients by meeting them where they are comfortable. I'm disappointed to say the least. I am going to download Chrome, but I'm not happy about it, and I'm sure there are many people who turn away from Hubspot services for having a preference for firefox. I can only think that Hubspot is falling short in regards to the ability and leadership of the company, to leave out such a large segment of firefox users. It would be hard to imagine that there is any good reason to do so, and even if there was, innovation is a part of a successful company. I will use Hubspot on Chrome for now until I find something better.
FWIW, the world of browsers is changing and FF is posed to gain a lot of users from v 57 onwards. I'm very concious about privacy, and FF is the only choice there really. The API for webExtensions is very close to chrome now, so it should not take a good dev more than a day or two to port it.
Now that the new Firefox versio is out I really hope HS will start acknowleding that Chrome isn't the only (nor the best) browser out there and give us a sales extension plugin that works with FF too.
Yep, this is sad. C'mon HubSpot, get with the game. Look right now, any of you have more than 10 tabs open. If so, Chrome has sucked all your memory. Not so with Firefox. Most of us deal with this daily and so Firefox is a good solution. I thought Hubspot was about making our lives easier; so let's see that extension. Please.
Like above, I've moved away from Chrome for both privacy and performance. I don't want to download Chrome ... so I guess I'll just give up on Hubspot since it looks like they're not really interested in making a FF extension.
Would love this. Was a long time Chrome user, but have switched over to FF because Chrome just eats up too much of my memory, especially after the latest updates. Is there still no solution for this? I know FF marketshare is declining, but still one of the top browsers worldwide.
