Firefox Community Forum

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?

Whenever I try to access the Powerball website I get the following response -

The request is blocked. 20260116T144515Z-17584c64c9f58vrnhC1MIAm1t80000000t4g00000000rcec

I have no issue with other browsers.

Thanks Gary

I have a very repeatable issue, that others have been dealing with as well, where Firefox will frequently disconnect Twitch chat after a period of time and go through a loop of disconnecting/reconnecting.

This is ONLY on Firefox, I can run Chrome or other browsers simultaneously with Firefox and Firefox will disconnect when others do not.

I am not sure what is occurring, but I know it only happens after a while. Like maybe after 30+ minutes of watching a stream, the chat will start skipping other users inputs, just show my own, then give me a Welcome to the chat connection and other messages will start appearing again. Once it hits this hang-up period, it starts disconnecting frequently.

I cannot find any resolution and there are no resources or articles about this, but I made a post on reddit and multiple users reported the same thing.

Afternoon,

I've used this account for a long time and today I had to reset my PC.

I was always signed into to Firefox to manage my bookmarks/passwords/history, however I've signed in now and everything is gone.

It won't sync up. I've tried removing the profile folders, copying them out, uninstalling/reinstalling firefox but nothing is working.

I tried to disable Windows defender, but that didn't do anything either.

The version I had at the time was Mozilla Firefox (x64 en-GB) Mozilla 147.0 which is the same version.

Is there anything that can be looked at, to see what has happened to the data I has?

I have had Google today almost lock me out of my account there thru various email accounts I have with them because they were not recognizing my devices that I always use daily and have for months and even years because of cookies that I don't delete and because I was not on the same browsers or accounts each time which I was unaware that I had or should stay on the same. So could I through you find out how to delete cookies that I have/had accepted in the past?

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?

418 Hello, I like your site (and I donate a little from time to time), but some of Firefox's behavior is becoming annoying: for months now, Le Monde articles have been cut off on the right (not those from Le Figaro), and recently Instagram has been blocking the browser after a few posts. Of course, it might be "their fault," but it's clear that it doesn't happen like that with Chrome. Good luck!

Firefox recently started asking for a profile when I tried opening a link from email but, not having a profile, I ignored it. If I copied the link into my firefox browser (already open) I could see the link contents, i.e. page(s) opened. Since then I have closed Firefox and now get asked about a profile and have tried using original and creating a new one. We have, unfortunately, reinstalled firefox so this is now more complex. At present, whether I login to Mozilla account or not, my passwords, history etc are no longer on my laptop, despite supposedly being connected. Firefox on my phone is currently the only source of my passwords etc, which is not good as I cannot export from there!

Can I restore this info somehow? We've tried a few suggestions found on the web, but no good yet.

Has something changed recently? My husband got the same profile request on opening Firefox but it worked when he selected use original/default profile.

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

So I guess my Firefox update to ver. 147 from 146 by its auto update feature, but I realized all the past personal data (ie, history, cookies, passwords, profile, etc) was gone.

I have Mozilla Account (I think it's the same as Firefox Account back in the old days), so my personal data is now retrieved from some device as far as possible, but I lost local personal settings like Shortcuts on the main page on my laptop,p which is the main device to do everything.

I can't help what happened to me, and I will rebuild what I used to be on that day, but I am curious if it's just me, or there is some logic to cause this data loss.

Why so many 'I am not a robot" picture checking and redundancy on motorcycles too? It's blocking my Firefox website address defaulting to Google's address bar? Only change I made was activating my AVAST security VPN subscription.

I am receiving this on many different websites including CDNs (such as served JS):

Content Encoding Error

The page you are trying to view cannot be shown because it uses an invalid or unsupported form of compression.

Please contact the website owners to inform them of this problem.

I verified it occurs in Private Tab mode too, without extensions. It does not occur in other browsers such as Chrome when I test the same URL. Clearing my cache etc does not fix it.

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...
