My Win10 & Win11 pc's updated to this version and they all have the same problem: The bookmarks have disappeared. Including my pinned bookmarks on FF's opening page.

I also just noticed that there are no "toolbar items".

The AI chatbot is back in my sidebar. I did not opt in to this. I would prefer not to roll back to whichever version of Firefox is before the AI it's-a-feature-not-a-bug got wedged in; what other options do I have for permanently disabling AI?

Going to sidebar settings to hide the AI chatbot does not suffice. Evidence: I did that already, it has been undone, and I cannot now find the toggle in question.

Personally I vote for yanking it out of the main browser altogether, so people have to actively choose to install the AI chatbot add-on. But my question is about actions I can take myself.

Today (06/12/2025) upon opening a new tab, Firefox slid the new option of uploading a custom picture to apply to the background. Tried the new feature, now I can not find the setting that allows me to change the picture. I read the thread "Customize your wallpapers". The instructions are as follows; You can personalize your Firefox New Tab page by adding one of the available wallpapers. Follow these steps:

  1. In the right corner of the New Tab page, click the gear IG settings icon.
  2. In the customization panel, under the Wallpapers section, you will see different categories like Solid colors, Abstract and Photographs.

       Click the category you prefer. For example, selecting Abstract will show a variety of abstract designs. 

The problem I have is the customization panel is no where to be seen, I have click on EVERYTHING possible, it is not in my settings, why? How do find this?

bookmark bar and all my bookmarks are gone I followed Support instructions, clicked on Manage bookmarks and went nowhere. I really need this function to work as I am sight impaired and can't use my phone for much. Please help.

I cannot change the background image when my Firefox app opens on my MS Windows laptop. During set-up, the system had me select an image, but I want to change it as I find it distracting. Thanks!

Здравствуйте. При воспроизведении видео на каком либо сайте в полноэкранном виде не скрывается панель задач виндовс. На других браузерах работает как надо. Менял где только можно, даже в безопасном режиме также. Как её можно убрать?

I'm trying to install Mozilla VPN but it won't install. The error message is as follows: the installer encountered an error that caused the installation to fail.

I received an email saying that I had to sign in in order to keep my account. I did not click on the link provided since I thought it might be a scam. Was this a valid email? If so, is signing in now meet the requirement to keep my account?

In what file does Firefox store information about the icons of added search engines?

(After copying the profile with the search.json.mozlz4 file, search engines added by the user work correctly, but their icons cannot be seen - each search engine is marked with the same icon 'magnifier' - as you can see in the attachment.)

I'm having some trouble with automatic translations on firefox. I don't know if It's exclusive of firefox, but some websites, mostly wikis, open a "translate" field that automatically creates a new website, wich causes the images and some other stuff on the website to break. I tried disabling the translation on about:config off, as show in some other questions, but it did not work. This is being really annoying because it keeps breaking websites unless i get to the original link.

Firefox now requires me to use a passkey to log in to YouTube. I don't have (or want) a passkey. My computer locks up solid, and I have to reboot when I cancel the request for a passkey. I can log in to YouTube on my Samsung S10+ tablet and S25 phone without problems. This problem only occurs on my Windows 10 computer. It is impossible to bypass this issue.

When I log into my Outlook Web account, after putting in username and password, it sends me a verification number to my phone. When I put that number it the screen says "Logging out of Microsoft Outlook" and then takes me to the logged out screen. This was working fine until the last update of Firefox, and it works fine in the Duck Duck Go browser. It also works on my Android Cell phone.

I have change my home page to DuckDuckGo, but when I click on a new tab, "+" I get Firefox. I tried blank and it is indeed blank, so how do I set new tab so it opens DuckDuckGo? (Read all help articles.)

I believe there was a button to send a url link by email on Firefox. I tried to find that button everywhere, but I still can't find it and it didn't even get to an answer for this by asking questions on Mozilla website. Could you kindly guide me where to find that button?

Thank you in advance.

For days I have been seeing Firefox be very slow to load a page (as in minutes) or stop working entirely. At the same time Chrome works fine. Mac Mail has become intermittent as well. I have uninstalled Norton products and changed Network proxy settings many times. Nothing helps. I have created new profiles. I switch between profiles. I have hacked into my WiFi router. Nothing, nothing helps. Safari hangs up too. Firefox on my android phone continues to work properly when using my Wifi router -the same router my Mac Studio connects to the internet with. I can access my third party mail service via Firefox on my android phone. Both FireTV devices work. I am at my wit's end. At this point I have shifted all of my work over to Chrome.

I have cleared caches. I have gotten rid of all cookies. I have restarted Firefox and rebooted my computer countless times.
