Diễn đàn hỗ trợ Firefox

FF is offering up possible login names for a particular site I have used previously even though I have removed all related browsing history, form data, and cookies (and cleared the cache). What am I missing? Is it using stored history for unrelated sites to guess at a user name, or is there some other hidden history I need to clear?

I use an online retailer to buy birthday cards and gifts - Moonpig.com. Whenever I choose Paypal as my payment option, it logs me directly into my Paypal account without me entering any details. I have several Paypal accounts and want to choose which one to use. I have no saved payment details on Moonpig's site and having checked, they say that somehow my browser is logging me in automatically. That's Firefox and I want it to stop.

I have no issues with Firefox storing log-in details but I should be able to choose which Paypal account I want to use.

Any thoughts please? UF

Firefox memorizes userIDs and I do not see an option to stop it from doing so. Is there an option?

Keep in mind that passwords are not limited to the password entry. Every entry in a sign-in process is an opportunity for a password. For example, the answer to "What street did you grow up on?" could be "Beatlejoice". Similarly, the answer to "What was your mother's middle name?" could be "Aardvark". Nonsensical answers to security questions are more secure than truthful answers.

Again, in the interest of security, is there an option to stop firefox from remembering so much?

Hello,

Several sites incorrectly tag their username (and sometimes also password) forms and this prevents firefox's automatic username/password autofil dropdown.

Is there a button or some way to force the autofil to appear? It is a pain in my behind that I have to manually open my passwords in firefox and find the page I am already on and copy/paste these things, just because some websites have strange HTML.

I understand that firefox can't override the HTML of these pages, but there should be some hotkey to force open the autofill dropdown (ideally with some sort of search function or selection based on url). It does also need to have an option to select whether I am pasting username or password.

Why doesn;t Firefox autofill my saved sites and passwords. I cannot find a setting for that. I don't want to go through all my sites to change passwords and don't know if I did would they then work to autofill. bold text

I recall that Firefox used to log-in automatically to websites that require a user name and/or password. This helpful feature seems to have been removed, even for sites that are listed in the "Passwords" display. How can I get it back?

I accidentally typed my protonmail password into the field of my username/mail address. I don't remember what more I did (propably answered yes to save) but now there is as autofilled my password for username always I open my Protonmail account. I am using Firefox as browser (should be the newest version) while Emailing.

I tried to delete autofill of Firefox according to the next advise: "go to Settings > Privacy & Security, scroll to "Forms and Autofill," and uncheck "Autofill addresses" to stop saving them"

Then I was astonished. There is no "Forms and Autofill" setting on my Firefox at all!

Protonmail settings didn't help either nor Windows 11 - neither FAQ.

I have been using 1Password 7 to manage my login credentials. It includes a Firefox extension to fill in account names and passwords in login alerts and pages.

Firefox 147.0.1 (macOS aarch64) in January 2026 has broken 1Password 7's ability to fill in account names and passwords.

To reproduce: 1. Install 1Password 7 Version 7.9.11 (70911000) and its extension version 4.7.5.90 in Firefox 147.0.1 on macOS. 2. Visit a URL for which 1Password 7 has login credentials. 3. Click on the toolbar icon for 1Password 7. A 1Password 7 dialogue box pops down from the icon, containing the username and password for that URL. 4. Click the Autofill button in that dialogue box.

Observed behaviour: 1. Username and Password fields remain blank.

Expected behaviour: 1. Username and Password from 1Password 7 appear in the Username and Password fields.

For approximately the last three months, there was a partial failure similar to this. 1. 1Password 7 popdown dialogue moves from the toolbar icon to the Firefox tab for that URL. 2. Username and Password fields remain blank. 3. Workaround: click in the username field, then tab 2-4 times to further UI objects in the login credentials form. Then click the 1Password toolbar icon, then click the Autofill button in the popdown dialogue. Then, the Username and Password from 1Password 7 appear in the Username and Password fields.

The expected behaviour occurs for the same URLs in Safari.

Thus I suspect that Firefox has somehow changed its behaviour in the last few months to cause this regression. I have not changed the 1Password software versions in this time, because I am intentionally using a previous version of 1Password.

I am looking for a fix or workaround which works with my current 1Password software version. I am not interested in a solution which requires me to upgrade to the current version of 1Password. (The current version of 1Password imposes a feature which I am resisting.) I realise that this reduces the chance that I can persuade the Firefox team to find and correct this regression.

I went into settings and searched passwords. then clicked onto saved passwords and tried removing what I thought was the password for a site. However when I log into the site the password continues to autofill. I'm wondering if I'm not getting to the right spot to deal with autofilling passwords?

I have two e mails, but when i try to go to my secondary email [email 1 removed]@gmail.com i always get my primary one, [email 2 removed]@gmail.com. why?

Bank site allows autofill for username but does not allow autofill or manual fill for password. Access to the site worked fine 3 weeks ago. Autofill works with MS Edge.
