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?

As has been mentioned many times before I am sure, it would be really helpful to be able to have a less laborious way to add exceptions but as I have been through the ridiculous process of typing in site addresses manually one by one without having any sensible way to record these addresses already I guess it won't help me now. The ridiculous aspect came from having to take screen shots of the list of sites from the manage data list after deleting everything not wanted, scrolling down a windows worth at a time, copying that screen shot into multiple copies of a graphics program then shrinking each copy of the graphics program and Firefox so each can be seen so I can manually type each address across.

I know I am supposed to be nice but this is just insane. It is 2025. There is a thing called copy and paste. Apparently some people at Mozilla are not aware of this.

Having got that off my chest the next issue is that the deletion of cookies and data only occurs when Firefox is closed. Who closes Firefox? Why would you close Firefox? I currently have 24 tabs open. Why on earth would I want to close them down just so they have to be selected one at a time and reloaded? What is the thinking behind this stupidity?

The only time I close Firefox down is when Windows is restarted for updates (every application) or when IDM needs to update as I found this negates the need to restart Windows (Firefox only).

Other than those situations I am trying to work out how to fit this cookies/data deletion into the normal operation of my computer. There appears to be a lack of a suitable way to deal with this situation. Would it be considered acceptable to just wait for those times Firefox has to be closed? This would be far better than what I have been doing up to now but why wouldn't Firefox delete this data when the last tab for a site is closed? There are a huge number of sites I bring up due to searching for something and close them immediately or after reading what they have to say.

I have been using computers for about 30 years and have long lost the inclination and to be honest the ability to delve deep into them. Today I just want to have them do what I want/need without unnecessary complications.

Have I got this situation right or is there something I have missed? At the moment IDM has been having a lot of updates thanks to YouTube's greed but before that I found I generally only had to restart my computer for MS updates and when strange things started to happen.

My passwords are apparently lost today after updating Firefox.

What went wrong? How could that happen? Why, Why Why?

Anyway to get them back? Are they hidden somewhere?

Anyone else suffering from this update too?

Any help or insights as to why would be greatly appreciated.

Hello- When I am on a website and click link I would expect and want a new Tab to open-- I want it to open it in a new Tab and leave the page I'm on alone so I can go back to the original page.

Instead, Firefox overwrites that page and the tab with the a new one, and I have to hit the back button to get back to that original page. And most often the back arrow button is grayed out and I can't get back at all.

In settings, I've tried checking the box for: 'Open links in tabs instead of new windows' but that doesn't do it. I've also tried checking the box, 'When you open a link in a new tab, switch to it immediately,' and that doesn't do it either.

I know that a work-around is to hold down the Ctrl key while clicking a link, but I'd like to set it as a default so I don't have to do that. That's a pain and not a natural function when browsing. To be sure, I want to click on links and that creates a new Tab without Ctrl Keys.

Thanks!

Hello,

I have version 143.0.3 (aarch64), running on a 2020 M1 mac. I did an update recently but I still have all of my bookmarks, that's not the problem. The problem is, although the space for the bookmarks toolbar appears when I click "always show" (and disapears when I select "never show"), I see nothing. Nothing shows up in this space and so I have to go menu diving to get to my bookmarks. Do you have an idea how to fix this?

For example when using Google translate there is an input delay, but it's only for Google Translate as other websites -- including other Google products -- don't have.

Hi, I have Mozilla Firefox for Windows. How do I do if I want to delete cookies from the past week? The clear history option only seems to have last hour, last two hours, last four hours, since midnight and "All history". I have a website that doesn't work that I suspect doesn't work due to a cookie issue (as it is a website that I have visited with other browsers and whenever I get the behaviour I just clear the cookies from the past visit and it starts working). I therefore need to remove cookies from the past week (or some other time period that I can specify myself), because only since midnight won't do and I do not want to remove all cookies since I got Firefox. Selectively removing cookies from one specific site is not an option etiher, unless I can remove them from the past week, as I don't want to remove older cookies from that site.

On all our computers it seems impossible to sign into Outlook...several laptops and 3 desktop...even a new Apple device. Enter your email address and then taken to the next page (see attachment). sign in works with Edge! This has been happening for maybe a month. Very frustrating! NEVER opens the next security window, the 'spots' just keep moving forever...selecting "Back" just repeats the cycle.
