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..

My browser is not working as it should. Several sites do not work anymore and the browser keeps crashing. I'd like to refresh the browser, but the button is missing. I tried going to troubleshooting mode, but the button is not there either.

Not sure if uninstalling would do the same thing? Just not sure what is the best way to refresh. Thanks for any help!

why am i being asked to sign in to age verification sites when i have mozilla paid VPN installed and have enabled japan as the start point rather than UK  ? - Thanks

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 had to actually sign up fort a Mozilla account,the multiple hoops I had to jump through were ridicules, in order to ask a question of Firefox. I do not want my address bar to be my search engine. How do I disable the search engine in my address bar? And now I have to wait for an answer!!!!!!!! I used to love and trust Firefox. Not anymore.

Recently, Firefox updated and ask me to setup a profile, which I have not yet done since importing my data from google chrome in 2025. After skipping the setup, Firefox then deleted all my data and it has since been irecoverable. I have already checked the box last update that specifically said to not ask me again for setting up my profile. After the recent update, the question popped up again and now I cannot recover my original profile, all my browsing history, all my browser-saved data, and all my cookies and logins
