Firefox Community Forum

I tried to open to a site WWW.RAFY-A.com this morning and got an alert it was not available, but, I am now unable to dismiss or close the following ATTENTION! messages. I did click on the "click here to secure your data! on the top two now it shows a yellow triangle which I'm still unable to close or dismiss. Could someone please explain how to get rid of these. I ran Dell Support Assist but I do not have a virus option. I have not rebooted yet as I wanted to clear this up first and then reboot. Thank you. Irene

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.

Hi, All of a sudden, I lost absolutely all of my bookmarks. My PC is running Windows 11. My Firefox account was and still is logged in. At first, I thought the data loss was due to a CCleaner cleanup using their latest update. After the data was lost, I tried running another CCleaner cleanup, but this time it didn’t delete the bookmarks. So I honestly have no idea how this could have happened. These were bookmarks I had saved over many years... It’s a disaster.

I have picked up some bug(s) on my Firefox that I cannot figure out how to get rid of. With a Firefox ID I have warnings of 3 Trojan Virus detected, Virus detected, hard drive infected, secure data notice and system alert. I also got a warning that my McAfee protection had expired which is very strange. Since switching over in 2010 from Windows to Linux I have never had protection of any kind and unlike Windows have never had a single problem. In addition when I was using Windows the protection that I had was never McAfee. I suspect that these warnings are not from Firefox given the misprints, spelling errors and the poor English. It is likely phishing from some third world country. How do I get rid of this obvious garbage permanently? Many thanks! Kris

Since yesterday, I have not been able to add new bookmarks. I want to add two new ones. (I can update or delete bookmarks.) I have read and tried the solution article (https://support.mozilla.org/en-US/kb/cant-add-change-or-save-bookmarks), but the fix did not work for me. I am using Windows 11 Pro (fully updated) and Firefox 143.0.1 (64-bit). By the way, Brave is my secondary browser. I can add the two new bookmarks in it without problems. Could someone provide a solution other than the one in the article that I have cited? Again, that solution did not work for me. Thank you.

I wanted to synch my current settings in my browser to import them on my new laptop. When I tried to login to my account, I the message from the attached screenshot appeared. So I created a new profile, got my stuff back to what it should be and then deleted the "new" profile. But now every time I try to get into the correct profile and login into my account, I still get the message from the screenshot. I never ever synched with another profile before and never had an issue in the past. Right now I am rather pissed off, because I lost atleast some of my bookmarks during this whole ordeal.

Не знаю по какой причине, возможно какой-то баг или ещё чего, но у меня пропали все вкладки, даже те, которые были сгруппированы. Возможности восстановления предыдущего сеанса у меня нет.

Good morning, I'm running Firefox Developer Edition 143.0b6 on Linux Mint 22.1. A couple of weeks ago I noticed that when moving tabs on the left-hand side they'll instantly get locked into an inscrutable and seemingly impossible to fix "pinned mode". Is there a way to turn this off? It is driving me crazy. I've looked through Settings > General > Tabs and about:config and didn't see anything relevant. If anyone has run into this or knows a workaround, I’d be grateful to hear it.

Every time I try to upload a file to the Microsoft Copilot 365 I keep getting the "Error Occurred Please Try Again" But when I switch to Chrome. I can upload the same files with no problem. Does anyone know why I get the "Error" with Firefox?

Think I've asked before, but I'm still having the same issue: in my Firefox (desktop, Windows 11), in the storage\default folder in my profile, there are, today, 5442 files! 416 folders appear here, with each one containing one or more folders ("Is", "idb", and/or "cache"), which, in turn, contain several files each, and a ".metadata-v2" file. The oldest of the 416 folders in 9/16/25. What is all this? I regularly delete all cookies over 30 days old in Manage Data.

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?

Hi, I just want to ask about the customization option on the new tab's low right corner (the little pencil icon). I've had a background image called "Galaxy" that i thought was pretty, but it disappeared (probably sync settings on other devices, idc) and now the background is just system gray. The issue is that i cannot find the system background in "Themes" nor in the "Customization" (picrel) - there is only "reset to defaults". I really like Firefox and this was pretty cool so I'd like it back. Thanks in advance :)

I updated my firefox to Version 143.0.4 (64-bit). (I am using Mac). I was trying to change my wallpaper, so I went to the pencil and customize part of the new tab, and when I look at the wallpaper thing, I just see that it says "Reset to default". I didn't see any of the things that said upload image or any of that. just reset to default. I really wanted to change my wallpaper, so is there something I'm missing or something?

cannot open or delete emails on google mail and youtube videos will not play. Had this problem a month ago. It's Firefox because I have no problem using MS Edge which I hate.

When I am scolling and the mouse hits an image, a large image preview appears. How on earth do I turn this off? I can see tab preview images to turn off but not this stupid image previre thing that covers everything I am trying to read or navigate on the web site.

Thanks very much M
