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.

hello. my name is Andrew. im learning the language toki pona. great language! however, it does not currently have support in Unicode.

as a workaround to use this language online, people have been downloading a font called nasin nanpa, and adding it to firefox's font fallback system in the about:config settings, and using the fonts UCSUR characters, like these 󱥬, 󱥂​󱤴​󱤧​󱤑​󱦐󱤄󱤽󱤧󱤊󱥵󱦑.

[specifically, the font uses codepoints in the Private Use Area because the language's script is not yet in Unicode. ]

the changes are to these settings.

font.name-list.cursive.x-western font.name-list.monospace.x-western font.name-list.sans-serif.x-western font.name-list.serif.x-western

recently, this system has stopped working. this change breaks multiple websites, including many discord community's that used the font to talk online in toki pona!

it also presumably breaks other fallback scenarios. now im guessing that this has not been noticed as most fonts support every commonly used character, making this feature rather obscure. however i really would love this to be fixed, and so would the large toki pona community!

to see what i mean better, please see the below images. the last image shows a website that loads this font on it's own, showing what the others should look like.

I have been battling with Firefox for a bit now with this 'helper tool' download. Every single update it requests access, which is has, and then won't actually open Firefox. I have to uninstall and reinstall each time to get some level of functionality back.

Checking online this isn't a problem isolated to my own computer, but aside from getting the pro version, there were no great solutions.

Can this issue please be fixed?

Firefox 147.0.2 (64-bit) on my Lenovo Yoga 7 Windows 11 Home has been randomly malfunctioning when i use the hover over tabs with the mouse to show what is in the tab (small image) Sometimes it just fails for several hours, other times it works fine on its own later that same day.

I have tried to find this inside the browser several times with trying to find this browser-tabs-card-Preview-enabled inside about:config But it doesn't seem to exist in this version and apparently you can't add a new rule inside the browser to solve it.

Google AI solutions search is outdated or the wrong version. My computer and browser are up to date. How do i fix this ? I don't want to uninstall it, lose my logins and the bookmarks if i am unable to sync my files after trying to reinstall the browser only to find out it has failed.

Hello, thank you for taking the time to read my request. I am a long-time user of Firefox, but recently I have encountered a series of bugs.

1. Initially, I couldn't access GitHub. On the same computer, Edge works fine, but Firefox fails to load the page. Sometimes, the page content loads in Firefox, but the layout is completely messed up, leading me to suspect that CSS files are not loading.

2. I uninstalled Firefox, deleted the profile, and performed a complete reinstallation. This time, I couldn’t even open the Firefox account login page, receiving the error `SSL_ERROR_BAD_MAC_READ`.

3. Following online advice, I set `security.tls.version.max` to 3, but the issue persisted. The error changed to `SSL_ERROR_RX_MALFORMED_SERVER_HELLO`. When checking the certificate, the common name was `n.sni-347-default.ssl.fastly.net`.

4. Suspecting an issue with the system or browser certificates, I deleted all self-signed certificates and self-signed CAs (such as Fiddler and Accesser) from the system, but I still cannot access the site.

Please tell me, how should I go about solving this problem?

您好，感谢您在繁忙之中拨冗阅读我的求助。

我是Firefox的老用户，但最近发生了一系列的bug。 1. 最初是github无法访问。在同一台电脑上，用Edge可正常访问，但Firefox无法访问。Firefox有时页面内容可正常加载，但布局全乱，怀疑是CSS文件未加载。 2. 我卸载Firefox，删除配置文件，完全重装。这次连火狐账号登陆页面都无法打开，提示SSL_ERROR_BAD_MAC_READ。 3. 我按照网上的提示，设置`security.tls.version.max`为3，仍然无法加载，报错变为`SSL_ERROR_RX_MALFORMED_SERVER_HELLO`。查看证书，通用名称为`n.sni-347-default.ssl.fastly.net`。 4. 怀疑系统或者浏览器证书有问题，删除了系统内所有自签名证书与自签名CA（fiddler, Accesser）但仍然无法访。

请问我该如何解决这个问题呢？

Whenever i go on my yahoo mail I get a security alert that says: we have prevented your access to cowhuntforenenst.com I have run my anti virus and malwarebites thinking it may be a virus but it didn't come up as one. And it's only happening on firefox not other browsers. Is there a way to fix this?

I have updated my firefox on W11 laptop to the latest version 147.0.3 (64-bit) but it cannot show any pictures from some, but not all, sites. Not from www.svt.se nor from www.yr.no But its ok from other sites, as www.tradera.com and www.kjell.com

It works fine using android firefox version 147.0.3

Any ideas, anyone?

I won't show my account information but when I try to access Amtrak's Guest Rewards site it goes into a loop. First it asks for username & password and accepts that with no problem. Then it asks for the code it sends to my cell phone and accepts that. And then it just keeps reloading various pages until I kill it. This is the error message shown in the log, it's repeated over and over:

NS_ERROR_ILLEGAL_VALUE: Component returned failure code: 0x80070057 (NS_ERROR_ILLEGAL_VALUE) [nsIFaviconService.replaceFaviconDataFromDataURL]

   loadFavicon resource:///modules/PlacesUIUtils.sys.mjs:220
   loadFavicon resource:///modules/PlacesUIUtils.sys.mjs:647
   setIconFromLink resource:///actors/LinkHandlerParent.sys.mjs:139
   receiveMessage resource:///actors/LinkHandlerParent.sys.mjs:60

LinkHandlerParent.sys.mjs:148:17

I'm running under Mac OS 10.13.6 The site loads fine when I use Safari (version 13.1.2)

Thanks

I tend to have long and extensive conversations on Firefox's Copilot AI but I've run into an issue that makes this more difficult. When I press CTRL + F to search for text through a chat, it only searches on the webpage I have open on the right. I was wondering if there is a feature that exists that does this that I'm not aware of, and if not, maybe that could become a thing later?

As I mentioned I can't seem to access my network folders. I only have this issue in this machine but I have my account on 3 different machines on the network with no issues. All have the same extensions and settings.

I need tutorial guidance to restore my home site. All has been eliminated except tabs. The more I try on my own to restore, the more that gets deleted. I need a phone number to talk to a customer care tech to guide me.
