Firefox Community Forum

After updating to latest version of Firefox, my request to go to website is showing "Access Denied" (e.g. www.aa.com)

Wie kann diese Auswalliste bearbeitet werden? Ich verstehe im Moment noch nicht, wie die Liste gefüllt wird. Ich habe beispielsweise NIUS nur 1x aufgerufen - und schon ist die Website in der Liste. Websites, die ich viel öfter besuche, tauchen dort aber nicht auf. Was kann ich tun? Danke für die Hilfe.

Nothing is working after updating to the latest patch.

NOTHING.

I cant open a new tab from any links at all. I cant copy an paste inside the browser AT ALL. My cursur looks like its about 25px off true. please roll this patch back ...why do they continue to allow engineers or coders to break it when it works fine?

I just started getting a message saying Facebook was breached back in 2023. Never got any message prior to this week. Situation is: I moved to a new city and can no longer see ANY of my passwords saved on Firefox. It's basically saying I have to change them ALL! Even if I tried, it's required to know the previous password to change the password on many, if not ALL the account passwords. The message says I was breached, but I wasn't. FIX IT PLEASE!!!

Hi, I just installed the latest update today and all my bookmarks disappeared and I can't find them to restore. I have a newer computer with windows 11 installed. Just wondering how to get them back. Dave

Since latest upgrade (1/16/2026) I cannot log in to Outlook email. This is specific to Firefox 147.0.1 (Chrome and Pop Peeper logins to Outlook work fine). I tried clearing cache, updating, restarting, rebooting, trouble-shooting mode, private window etc. to no avail. I get 400 error from Outlook.

Background is a little complex. We have been running Win 10 under the ESU, My wife had her box unintentionally do a Win 11 update. She then started a backup which then looked like it would take days, so she aborted it after a while and ran the procedure to revert to Win 10, which then completed successfully. I think she then rebooted and opened Firefox and all her prior windows were there and working, After a while they got slower and slower, so she closed Firefox, might have rebooted and restarted Firefox. She now has 37 windows that are all completely blank. There is a New Tab tab and now URL in any window,

Is there any way that would likely recover all those open windows? Or, at least the URLs of all the tabs?

I have discovered Major problem with Firefox which affects the use of my btinternet.com email account . Since the recent update I am no longer able to add the contact name to a new email which I wish to compose automatically from my contacts (I am required to type it in full. I can still do it, with the shortcut of typing in the first 3 letters, when using other browsers such as Google or Edge or the Outlook muti mail account service but generally prefer Firefox. If this situation prevails I will ditch Firefox as speed of communication and addressing is of the essence to me. Are Firefox aware and are they correcting things?

Could any settings have been altered by the update - which contribute to my problem?

Hi, Recently and despite upating to the latest Firefox Browser, when I try to use BT Email groups it offers it as I type and I select. It then just shows the first character of the group or email surrounded by a red box and a x next to it and doesn't expand into the members of the group. This automatically suplied email recipient address is invalid. I've tried clearing the cache for the webpage to no avail. The problem doesn't occur in the Chrome browser. Kind regards Michael

I can delete history entries in a date range from today, 1/16/26, back to 1/10/26, but not 1/09/26 or before. Is it intended that earlier history is to be not deletable?

Windows 10 Firefox 147

Hello all, I have two HP computers running Win10 home on the ESU program and will be buying new computers in several months with Win11 factory installed. One is an Omen desktop and the other is a Envy laptop. I noticed in my Event Viewer after updating Firefox to 147 that I am now getting three consecutive 10016 DCOM Warnings every time I open Firefox. This has never happened before in all the years I have used Firefox. Now I completely understand that we should just ignore 10016 DCOM https://learn.microsoft.com/en-us/troubleshoot/windows-client/application-management/event-10016-logged-when-accessing-dcom but I find it strange that all of a sudden it is now happening and only for Firefox and on both computers. I do have the procedure to fix DCOM errors but do not like messing with the registry and permissions even though I have in the past with no problems but there is always that chance that it could and I do not want to risk it. I was wondering if any other users are seeing this in their Event Viewer System Log for Firefox or is this a known or unknown Firefox update problem or what.

Respectfully, Don

The update alert had a "download" option which I clicked - no warning or info... Later, after probably (?) applying the current update, I remembered the saved download file and executed it, as I thought I was supposed too (why else suggest I download it?) It seems to have guided me thru an initial installation, with no warning that I might be wiping out my finely working 10-year working version of Mozilla. I could have stopped along the way (maybe?) as it wanted me to "Complete Installation" but I drove on, fearing since I'd already installed it, it was to late to back out. Felt trapped and in fact now have a very different looking (uglier) Mozilla than I was familiar with, and have lost all of my old Bookmarks! There was no warning to save the old once first to later re-install. Basically the install from the downloaded file should have noticed that I already had Mozilla installed and warned me about proceeding, but it did not! Grrrrr! That's my complaint!

Oh, doing this on an HP laptop, Windows 10 with purchased extension of Windows 10 support...
