Firefox 技術支援討論區

Hello everyone,

I'm currently consuming APIs hosted on an external server using Java( or any other server side language), and everything works smoothly. However, when attempting to consume the same APIs in JavaScript, I encounter the 'Access-Control-Allow-Origin' error.

After some research, I discovered that browsers implement security checks leading to this issue. Can anyone advise on how to disable these security checks or resolve this issue when accessing the website in the Firefox browser? Any insights would be greatly appreciated. Thanks in advance!

Hi, Mozilla Relay/mask is connected to an old, defunct email address. How do I change that? The verifications are going to the old address that I can no longer access.

So I have two different accounts for one website. However one of them I use very rarely, maybe once in 2-3 months the other one i use almost daily. Therefore I have saved both logins in Firefox and I can see them in my passwords.

The problem is that whenever I try to access the website, Firefox auto-fills the "second" account, the one i only use rarely. What this means is that instead of me being able to just press login i have to delete the username filled in by Firefox and select the other one. So what i would like to do is to maybe tell Mozilla that I want it to use the other account for auto-fill.

Hi, I want to delete my acccount entirely and start fresh, I login to the website just fine, but when going to the "Delete Account" button I keep getting an "Incorrect Password" pop-up.

I've changed the password twice now, logged in just FINE, yet keep getting told I'm using the incorrect password when trying to delete my account.

I've tried on multiple different browsers now to delete the account and it's just not working.

I really wanted to swap over to Firefox but everytime I try, I get some insanely stupid issue that never ends up being resolved, I've found another thread from 2021 about this and they stated it never got fixed and they had to make a whole new email just to use the service.

During my absence my house maid created a Google account for herself on my Firefox browser, which is confusing my browsing as it is also a default account. I wish to remove my maid's account but cannot find how. Please help. I am using Windows 10.

I am trying to log in to the Tesco retail site, and get this message: Access Denied You don't have permission to access "http://www.tesco.com/account/login/en-GB?" on this server. Reference #18.26cc19b8.1700734342.438f9dd8 This is a new problem - it was working fine a week ago, and I have made no intentional changes to the Firefox settings. I went to the Settings: Enhanced Tracking Protection, changed it to Standard, and added the Tesco site as an exception (this was following the advice on some other "Access Denied" posts) but it made no difference - I still can't log in. Everything works fine on Chrome, but I would prefer to keep using Firefox if possible. Any suggestions? Thanks

I recently took a hit from potential malware while looking for a owners manual. I now have a popup that looks like the one attached. It looks to be from Mozilla, but I can't be sure. Can you help with this?

My Windows Task Scheduler contains an entry called "Firefox Default Browser Agent". If I delete it, it returns. If I disable it, it re-enables itself. Can't be modified either. How do I turn it off permanently?

I already have telemetry and automatic updates both turned off.

In about:config default-browser-agent.enabled is set to false

the Ask to Save Website Passwords Option keeps Deselecting itself, it will not stay selected

Because of that, the Auto fill Username & Password fields do not populate.

I have already Uninstalled Firefox, removed all files from my system, deleted all Firefox App Data from my system, Reinstalled Firefox from Scratch, reconfigured all, but can not get this working correctly

All of a sudden the Firefox password I've been using for a long time stopped working. I went through the reset process, set a new password, and it still doesn't work! What I am doing wrong? Keeps asking me to re-enter the password, and when I do, it says it's not correct. Is this a widespread known issue?

I'm a software developer working on some web application and sometimes need to manually add URL components in the address bar of an open tab simpyl to test something. For example I have some tab open shwoing the web page under "http://localhost:8080/entry" and I need to test "http://localhost:8080/entry/foobar" by manually adding "/foobar" to the URL. Depending on if "/foobar" exists or not, either some web page is shown or inc ase of a HTTP status code 404 Firefox automatically opens a new tab and forwards my input as search to Google.

That is not what I want. I want Firefox to simply show the HTTP status code 404 like the other browsers I use. Though, I want to be able to search in the address bar in general, only not in case there's an existing working URL open already and I change the child path only.

Is there some way to disable the behaviour of Firefox for 404s or do I need to completely disable searches in the address bar instead?

Thanks!

How do I get Firefox to stop suggesting my email address, city, state or other information on lines for logins or applications? I have turned off all the autofill selections in security and privacy and it still offers suggestions. I don't want any suggestions AT ALL.

When a "+" sign is entered, alone, into address bar, a list of some visited sites instantly appears. How do I delete these sites and prevent sites from being saved in the future?

I've searched everywhere I can find for an answer to this question, or for a place to submit it, and failed.

In Privacy & Security > History I've un-checked all except "Clear history when Firefox closes" which is checked. In > "Address Bar--Firefox Suggest", I've disabled all options.

I clear "Recent History, Everything" (Cookies and Site Settings are left unchecked) frequently.

Thank you for your help!

I can't seem to access one website that I used to visit daily: www.leftwinglock.com

I have no issue with any other site that I visit daily, and my co-workers are able to access that site so it is not down.

Is there something in my settings that is preventing me from viewing this site now?

Thanks.
