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 enabled two-step authentication on my Firefox Account by clicking on "Add". Everything went OK. (It was the first time I enabled it. I've been negligent.) The "name" (email) on the token generated by my 2FA App was the primary email of my Firefox Account.

Then I clicked on "Change", and followed through the same steps as when 2FA was "Added". Now, the "name" on the generated token was neither the primary or the secondary email of my Firefox Account ! The name on the token was the email I used as the primary email of my Firefox account back in 2020 ! Despite the wrong name (email), the 2FA code worked fine for signing in. How and why does this happen? What is the intended purpose of the "Change" option?

I fixed the name on the token by Disabling then Adding 2FA again.

A Curiosity?: When I try to sign into Firefox account, 2 emails are offered by Firefox - the current primary email for the account, and the previous primary email for the account. The second email IS in Logins, but not for accounts.firefox.com. The 2nd email is rejected if it is tried to be used. Where is Firefox getting the previous account email from?

Hello, I imported Bookmarks when I came to Firefox from a previous browser. The experience was terrible and challenges still linger. Firefox has come a long way, however UX still seems to be a 2nd class citizen. Bookmarks now has somewhat duplicate directories and this in turn is causing desktop/phone sync doubt and is likely missing bookmarks.

When sync breaks, it is so confusing. How can I simply have a working Bookmarks sync on desktop/phone?

Perhaps there was a challenge when I need Bookmarks to appear in the top bar when a new Tab is opened, as this was contrary to default Firefox settings.

when i click file, email link a pop up appears and says the file does not have an app associated with it for performing this action. I have refreshed firefox this did not work and i have checked that the mailto is set as thunderbird.

Help! Why aren't favicons showing up in my bookmarks? The favicon is there in the first screenshot, but when I moved the bookmark to the folder in the second screenshot, the favicon was already gone!

ok so this problem has been bugging me since i switched to firefox, back in chrome, if i type nexus at the search bar, the first suggestion would be my most visited url at nexus which is nexusmods.com/skyrimspecialedition how to make it so firefox would do the same?

looks like i put in two accounts by mistake and it is taking up space i need to sync my iPhone and i don,t know if i remove one will it affect the other one. Or should i remove them both and start again?
