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

Followed unstall and trying to remove remaining folders, data from computer.

I cannot del these folders, etc despite being admin mode or from command line.

whats next.

I want to do a fresh install of Firefox but wont install firefox again if I have to an computer reimage.

After the last Firefox update the Home Screen Short Cut List is populated with every link I access on the Web. I don't need a short cut to everything I might view in a days time. That's what my History list is for.

The top two toggles in the "location" area of privacy settings are OFF. Greyed out. The rest are also in the off position and greyed out other than "Notify when apps request location" is toggled on. I accidentally said "yes" when it wanted me to share location. (I just started using Firefox last night). Then it opened my "settings" for my computer on it's own and I closed it out quickly as I was working on something important and I cannot have distractions. I did not mess with any toggles or click anywhere else except the big X in the right upper corner. Since I didn't mean to click yes now it is prompting me quite often, every few minutes, to turn the location service on and automatically opens the settings for my laptop to the page "Privacy & Security > Location. How do I get this Madness to stop?

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

Anyone use LastPass? Do YOU have any hair left? How do I put that extension up at the top. Where my red arrow points? ALSO......

Im entering the email and password i swear dozens of times every day...it never works right, ALWAYS need one or both lines filled in.  I DONT CARE IF IT DOESNT WANT ME TO SAVE THE PASSWORD. GOD KNOWS its NOT retaining it!  OK, im 75 years old. HAVE I LOST MY MARBLES?

I used to have about 40 quick links, or bookmarks on my home page. I had pinned several. Others appeared according to how often I used them. The latest update deleted all but 3. I am very unhappy. How can I get rid of this update and bring back my quick links? I guess I will have to go back to Brave.

I love my current Firefox settings, bookmarks, folders and color, background image, dark mode. All I want to do is to create a Firefox browser backup file. I don't want to restore or sync anything. I just want a backup file in case of computer failure to restore to my next computer if ever necessary. I'm using Windows 10. I think they used to be "json" files? The only "Backup" link in the menu only addresses Restoring from a file. I just want to create a backup file for this current browser just the way it is. Is there a simple solution? Thank you SO much!!

Hi,

On the "Your Firefox has updated" page, I recently found out that in addition to Firefox Sync, you can also create a backup in the form of a local file. When I try to follow the instructions on the support page for the function (here I get stuck. For some reason I am only allowed to choose a file to restore my data, but I am not allowed to create a new backup. I have tried refreshing Firefox and even creating a new profile, but both have the same issue. I am not seeing a "manage backup" button either (see screenshot).

It's not the end of the world thanks to Firefox Sync, but I would like to get it working as a nice backup :)

Thanks in advance for any help you guys can give me!

Do you have a real person, not a AI, programme, or any else? I want to talk to a live person. This programme I am currently trying to deal with is NO HELP

How do I get the Block Element feature back on this machine?

the Internet is getting harder to use with each update any programme adds.

I have Windows 7. I do not like any of the later versions. They do not work as well as Windows 7.

Please tell me how to contact a REAL LIVE PERSON WITH A FUNCTIONING BRAIN.

Every time I try to open Firefox Mozilla this pops up:www.expedia.com/identity/api/v1/oauth2/callback/google-web?error=access_denied&state=MuRPJl7NGKnHkJs3P3gwVI9MUOzHbdnYA1eA8_aRTcA

How do I get rid of it? I have closed it but it returns the next time I try to enter firefox

Maybe that's at the root of the problem I'm constantly having with my history & bookmarks being unavailable every time Windows updates? The strange thing is that this page shows that Firefox does know I'm using 11.

I've already posed the question I have about resolving that matter. Hope this helps someone figure out the answer. Thanks to whoever tries!

Hi,

Looking at my Firefox 147.0.1 settings for macOS 26.2 (Apple M1), I'm trying to adjust two settings:

-- I'd like to remove Languages -> English (GB) (its existence has odd side effects, like triggering United Airlines to offer fares in Pounds Sterling, and I'd prefer to just have English (US))

-- I'd like to disable Play Audio and Video for about:welcome (in regular and private windows)

I can see no way to accomplish this currently -- why?

Thanks.
