Firefox Community Forum

In my new PC on Windows 11, I decided to install the Mozilla Firefox from the "Microsoft Store". However, unfortunately, I realized that some Add-ons (extensions) where missing from the Firefox's "Gallery of Extensions". Among them, the well known and valuable extension '"Enhancer for YouTube", which I have installed on every browser that I use. So, if I don't find a solutions for this issue, I am about uninstall the Firefox and reinstall it from Mozilla's Website..

Hi everyone,

I recently built a small Firefox extension for my website https://calcolo-stpendionetto.it https://calcolo-stpendionetto.it , which helps users calculate their net salary in Italy using updated IRPEF and INPS rates.

However, when I try to upload the extension to addons.mozilla.org addons.mozilla.org (AMO), I keep getting this error message: Signing is not possible due to an error with the manifest file

{

 "manifest_version": 2,
 "name": "Calcolo Stipendio Netto",
 "version": "1.0",
 "description": "Calculate your Italian net salary (IRPEF, INPS, regional tax) quickly.",
 "icons": {
   "48": "icons/icon48.png",
   "128": "icons/icon128.png"
 },
 "browser_action": {
   "default_popup": "popup.html"
 },
 "permissions": ["activeTab"]

} I also tried switching to manifest_version 3, but then Firefox gave a warning that some properties like browser_action are deprecated or not recognized.

Has anyone experienced the same issue when uploading finance or calculator-related extensions? Is there a new manifest format or signing rule I might be missing for Firefox extensions?

Any help or examples from working extensions would be greatly appreciated. Marien Klin

I want to use the AI sidebar (https://support.mozilla.org/en-US/kb/ai-chatbot) and context menu to query my own chatbot. How to add my own chatbot(s) there?

I am trying to open a site, but keep getting this message: "Before you continue to the website...

By clicking the "Accept and Continue" button, you will be redirected to the Firefox Add-ons Store to install this extension. By clicking the "Accept and Continue" button and installing this extension in your browser, you accept the Terms and Conditions, Privacy Policy, and agree to select "Recipio" as your new search engine. Firefox Add-ons Accept and Continue" I do not want to add it - why am I being forced to add it?

Is there a way to completely uninstall only the adobe plugin???

I recently wiped & reloaded my computer. Multi-Account containers re-installed successfully & I see all my containers. The issue is with sign-in to Reddit.com website. If I try to login using a container, I get invalid username or password error. If I login without using a container, it's fine. I am copy/pasting my account info. I tried different containers; same issue. Tried creating a new container; same issue. Try again without using a container; login to Reddit is successful.

Hey folks, just wondering when the Windscribe add‑on will be moved to the MV3 framework. Other browsers already have it at v4.x and I’d love to see Firefox catch up so we can use the new privacy features. Is there an ETA on the review/approval process? TIA

I'm chasing a problem with 1Password not auto-filling fields. please can you tell me how to delete Firefox and extension then re-install both. Firefox 146.0.1 MacOS 15.7.3

Thanks and happy new year
