Firefox Community Forum

I have just had to replace my PC following a bit of a disaster with my old one. The new PC has Windows 11. As usual I downloaded Firefox as I always use this. Somewhere in the installation of Firefox I must have been asked about blocking ads, but I don't remember. Now all ads are blocked, which I don't mind, but some sites are asking me to disable my ad-blocker if I want to use their site. Mostly I don't but there is one I need to use, so I would like to add that site as an exception, but I cannot find any mention of any ad-blocker in settings. Where do I find this? and how do I add exceptions?

The only add-on that I have in Firefox is the 'Privacy Badger' which could be the problem I suppose, but I can't see the website listed in the ones Privacy Badger is blocking.

Any help would be appreciated

When using Firefox to access certain sites on this laptop such as Marriott.com, United.com, AA.com and Spirit.com, after I login and start a search I get an Access Denied message. However, when using Firefox on another laptop I am able to d a search for a reservation on these sites. This leads me to believe a setting on this specific machine has been changed and I do not know how to correct the situation.

Access to the above sites works without any issues on Chrome or Edge.

Warning: Potential Security Risk Ahead

Firefox detected a potential security threat and did not continue to na.nikken.com. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

What can you do about it?

Probably nothing, since it’s likely there’s a problem with the site itself.

The site is ok when I open on another window and even on Google which I don't like.

I cannot get the bookmarks toolbar to show "Other Bookmarks" on the right end of the toolbar. When I right click on the toolbar, the option to "Show Other Bookmarks" is greyed out.

I completely uninstalled Firefox, deleting all residual files and registry keys, then reinstalled the software, and it hasn't fixed my issue.

I cannot find any support forums or articles that have provided a solution.

Here is the message I get when trying to access Kroger's website (and a few others). Access Denied You don't have permission to access "http://www.kroger.com/" on this server.

I am having trouble signing into some of my web sites. This problem just started. I have tried everything even uninstall and re-install. Nothing works. What do I need to do?

I cannot access my xfinity account due to my anti-virus (Eset) blocking Firefox's access to assets.xfinity.com

Hi, for about the last week (23 Feb 2026) when watching videos in my Firefox Browser, there are short stutters. First noticed in Youtube, so looked for updates to UBO and other extensions. Then noticed the same thing in BBC iPlayer and my4 streaming. It also happens when watching my media via Plex in the browser. It is not my network bandwidth or speed.

When I watch media via my Plex app or videos on VLC media player, there is no stutter.

I have included a link to logs recorded in Firefox profiler as suggested by someone on Reddit. firefox_profiler_2March26 https://share.firefox.dev/4b4moC0

I don't know if this is caused by a Firefox update, a Windows update. Laptop: Asus ROG Flow X16 (2023); Intel i9-13900H, Intel Irix Xe; NVIDIA RTX 4070 (mobile) Firefox 148.0 (64bit)

All drivers up-to-date. Please let me know if the link does not work - my first time trying to upload a link from profiler.

Thanks all.

I use Firefox as my desktop (and phone) browser. Recently my desktop cannot open my USBank Online banking service (my Android Firefox phone browser works fine). The USBank customer technical service agent tells me that their software does not recognize the Firefox browser - he says that AVG Secure, Microsoft Edge , and Google Chrome work fine). How do I rectify this without changing browsers? I've used Firefox for opver a decade without trouble. Help!

I know that there is already default containers built-in without the need of the extension. But there's no way to open tabs in containers when we click a link, only when it's typed in. There's an option in settings that allow to pick a container when a new tab is opened, but that's it. It would also be great to move the Mozilla VPN and integration and sync function from the extension to the settings page for easier access.

Ich habe die Passwortliste bei Einstellungen aufgerufen und die war leer und alle gespeicherten Passwörter waren weg. Ich habe sie aber nicht gelöscht. Wie kann ich die Liste mit den Passwörtern wieder wieder herstellen ?

This is a new laptop. I have it established to open previous windows when I turn the laptop on. Firefox is also supposed to automatically start. Neither thing is happening. Why?

This has started a few days ago. I'm running Firefox Desktop on Windows 11. Browsing is perfectly normal, until I try to watch a video in full screen mode. It plays normally for a few seconds and then my whole system freezes, with no response to any action except for hard reset. This has never happened to me before, and all other browsers I try do not demonstrate the same problem. Is there any solution other than changing browser permanently?

I logged into my computer this morning and opened up Firefox, went to a online account to login and clicked on passwords from the sidebar and when it opened up it stated that I had no passwords saved and my profile had also been disconnected. I reconnected with my profile and all of my passwords are missing. Where are they?

I have been using the same firefox account for six years, and when the update that added user profiles came out, I successfully transferred all of my information to a profile. Well, today my firefox wasn't responding, so I used task manager to close it and restarted my computer. When I opened firefox again, it prompted me to select or create a profile to continue browsing. Crucially, it did not list the profile I had been using as an option, so I created a throwaway profile so look up what was going on and how to fix it. I tried logging into my mozilla account; no record of my previous browsing data, bookmarks, or extensions. I tried following the steps in the "Restore bookmarks, passwords and data from an old Firefox profile" article from Mozilla Support, but my old profile no longer appears in the profiles folder on my computer. I'm worried that if I keep messing around trying to restore my old data, I'll do some irreparable damage and never be able to get it back. Is there anything I can do in this situation?
