When trying to access many popular websites with Firefox on my Fedora 43 installation, I am greeted with a security warning page with the SEC_ERROR_UNKNOWN_ISSUER error. For most of these websites I can simply accept and continue, but HSTS-only sites will not permit this.

Affected websites include but are not limited to (based on exceptions in the certificates section of Firefox settings):

• github.io (many subdomains)
• purdue.edu (many subdomains)
• iu.edu
• ebay.com
• cbsnews.com
• iwm.org.uk
• home.cern
• celestrak.org

Any help in resolving this is appreciated.

The AccuWeather part of the Firefox homepage says I'm in Portland, Oregon, USA, but I'm not even in the same country. I tried to change it according to the directions I found earlier, but the only drop-down for my city was another city in the US but none in any other countries. So now I can't change my location. How do I change my location? It wasn't like this yesterday and I have no memory as to how it became "Portland, Oregon" since last night. I don't even have a VPN so it isn't that. How do I change it back to my area without using my exact location?

!. link to youtube only flashes then plays only audio. Full video requires opening link in a new private browser window

2. Typing into search bar for Duck Duck Go in new tab page types directly into active bar...

3. Active bar is no longer at the top but is in Bookmarks toolbar...

I suspect some update problem.

Hello,

Today I updated to Firefox 143.0.3. When done (most of?) my add-ons were gone, in particular all my add blockers, facebook container, etc. Also, my search engine defaulted to Google (yikes!)from Duck Duck etc. I am very specific about trying to block all ads, trackers, etc and avoiding all Google products. Other things stayed the same like cookies preferences.

Is this done by design? Is there a file somewhere that still has all my add-on info, that I can restore.

I really would give up on browsing if I am forced to see ads all the time.

Thank you! Petrus Martens

I'm using Ubuntu 24 with the XFCE desktop. I'm installing the debs straight off packages.mozilla.org (currently 143.0.3).

Firefox's title bar, and window manager buttons do not have the same look and feel as the rest of my windows. And I have no idea where they're coming from.

They do change appearance in response to picking the different styles in Settings > Appearance, but the changes appear to be limited to colors only. The minimize, maximize and close buttons look differently than on all other windows, and they are more spread out than in, and the shade button is nowhere to be found.

I'm attaching two small images, the first one is the standard set of widgets all other windows have, and the second one is Firefox's odd duck. I could not find anything in settings. "Extensions And Themes" shows that "System theme" is enabled. Well, it's coming up a bit short...

I PAID for "dark reader" I got the activation key but I cannot activate it because the instructions says go to "MORE" and there is NO "MORE"! I hunted all over the settings & extension & themes, but I cannot find anyplace to activate this extension. Did I just waste my money? I have poor vision, I NEED a dark page with white letters. Thanks to being a touch typist, I don't need to see the keybord or page to type but i can't see what I am typing on a dam w hite page! I now cannot click on "Email me when someone answers the threadil"

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?

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.

I cannot login into a website because they complain that I have an old version of PHP. Is that already included in Firefox? I am using Firefox Vers. 143.0.4 on a MacBook Air with MacOS Big Sur, Vers. 11.7.10 Shall I go to the PHP website and download PHP?

Hi,

I can't seem to retrieve all of my Firefox bookmarks or passwords on this new mac laptop. My other (mac) one fried. I thought everything was saved on Firefox.  Tried to sync from phone (android) too. Therefore, I'm having a hard time logging into certain accounts, which I depend on Firefox for my saved passwords. (evidently that is a thing of the past and I will now write all passwords down in a safe place. Also does anyone know why when I scroll on my mouse I have to scroll up, in order to scroll down, more importantly how can I change it back. This is a new glitch. and I'd rather not get used to it! Please help if you can.

Thank you, techno dummy Noel lol

Hi Firefox Team,

I know how hard you guys work and I've used you almost exclusively since the beginning in 2003 and talked a lot of folks into switching to you over the years.

I'm so frustrated about your decisions to change the options for what we users want on our home page and new tabs. Seems I can only use a blank page or your default home page. And if I want my normal home page I need to click on the home icon. In the course of a day, that's a LOT of extra clicking or the alternative, typing my search query into a tiny URL bar.

Are you planning to change this? Or is this Mozilla control by default the new norm? I'm so sad to admit to be exploring Mullvad and Brave now. Never would have even considered it, even though I'm consciously weaning off other US digital products.

Thanks for any suggestions and for all you do. (Yes my IOS is up to date)

Pen

Firefox is the default browser and pinned to the taskbar. When clicked, Firefox automatically opens places an additional icon in the taskbar. Once Firefox opens, in the second icon, any new links open in tabs, which is my preference.

The first image is the pinned icon in the taskbar. When hovering it only displays Firefox. The second image is the additional icon, when hovering over this icon the active page thumbnail is displayed.

Prior versions of Firefox did not have this behavior on my Windows 11 desktop PC. I've tried various settings in about:config but cannot resolve this issue. Is there some reason two icons are now required in the taskbar when running Firefox?

Tôi muốn hỏi rằng Mozilla có kế hoạch nào để tích hợp sẵn tính năng dịch trang web từ các ngôn ngữ khác sang tiếng Việt trong trình duyệt Firefox hay không? Đây là một tính năng rất cần thiết, đặc biệt là đối với tôi khi thường xuyên đọc tài liệu nước ngoài. Việc gặp phải những từ khó khiến quá trình đọc hiểu trở nên chậm hơn, vì vậy nếu có sẵn tính năng dịch từ ngôn ngữ khác sang tiếng Việt thì sẽ vô cùng tiện lợi và hữu ích. Tôi nhận thấy hiện nay trình duyệt đã hỗ trợ dịch từ tiếng Việt sang tiếng Anh, nhưng chiều ngược lại thì chưa có. Rất mong cộng đồng hoặc đội ngũ phát triển có thể chia sẻ thêm thông tin về việc liệu tính năng này có nằm trong kế hoạch phát triển tương lai hay không, và nếu có thì dự kiến khi nào sẽ ra mắt. Xin chân thành cảm ơn!

Two QNAP NAS displayed readable web pages this morning. Early afternoon I updated Firefox with a reset and the admin pages on both servers are unusable. How can I roll back Firefox or recover the earlier version?

Anybody else notice that when using the back arrow on some sites, it just won't stop back-arrowing? I mean, usually, when you have reached the very first site opened in the current tab, the back-arrow will grey-out and become non-functional. But some sites are allowed to embed an instruction which causes Firefox to just keep on back-arrowing indefinitely, without EVER greying-out the back-arrow; it just keeps on re-loading the same initial web page. The yelp.com website is a good example of this behavior. Firefox should prevent sites from embedding functional-override coding which causes the browser to behave abnormally like this. Another functional-override example are websites that, DESPITE having a global Firefox browser setting to NOT auto-fill fields, the site causes Firefox TO REMEMBER the data anyway, and then to re-display the data at the credentials step as a pull-down menu underneath the Username field and, more often, the 2FA field. Haven't seen any site yet override the no-auto-fill setting for the Password field, however...luckily.
