Hello people,

I have a problem. At the moment I am running a Firefox version 143 on Linux with different windows. At the top left you can then select which windows you want to use. Only now it has disappeared. You get a home page. I have tried several solutions. Anyway, how do you get the rest back? Thanks.

TV will not play programs. It brings up the app but when I select a specific program I get "We are experiencing problems with our servers. Try again later". It works fine on Opera,Edge and on iPhone. I noticed that Firefox does not store my location in the same place as other browsers and wonder if that is the issue.

Hi, I am using Firefox to open my different mail boxes from : yahoo.fr or orange.fr or laposte.net. Usually everything are going OK and I can read the attached files except the one sent by my friend from England. Sorry for my English but you may have understood I am french (nobody is perfect). Well, I am using windows 11, he is using windows 11 ; I am using Firefox but he is using mainly Microsoft Outlook. All his attachment are coded as winmail.dat and I can't open them. If I use Microsoft Edge it's not much better. When he uses Chrome and Gmail it's perfect and I can open his attachment with Firefox. He is a computer man, programmer, and his Outlook seems to be correctly set and he doesn't understand the problem or what's happening. I am not the only one in that case. It seems it's an Outlook setting specific problem according to Microsoft. Clearly, I don't want to give up with Firefox. Does it exist an add-on or extension for Firefox which could solve this difficulty ? or a decoder add-on ? It seems there is at least one for Thunderbird but 6 yo... Would it run under Firefox even it's specific ? For fun I should try Firefox with Linux just to see if Linux is better at decoding winmail.dat attachments. Thanks for any help, setting or specific add-on you can provide me. Richard.

I tried Mozilla Monitor, logging in using my Mozilla account, but it wouldn't accept my UK address. It would only accept USA addresses. So I was not able to run the scan and reach the stage where you can delete the Monitor Account

Using the same personal data, but selecting a USA location, I ran the scan and then dieted the account successfully.

As I used the same email address for each attempt does the successful deletion on the second attempt mean all my Monitor accounts have been deleted?

ChatGPT indicates that this is the case but I would welcome further advice.

Now that my browser is Firefox I cannot get to my email or anything else on my computer. What must I do??? At one point I was signing in to Mozilla Firefox and it said that account already exists. This is very frustrating for an older geriatric. Please send me instructions to get back where I was. My present email address is [edited from public] @gmail.com.

I reinstalled the operating system, so to speak, changed my device. I clicked the sync button and it worked. I reinstalled the operating system and reinstalled the browser. I logged in, nothing happened. I rebooted, nothing changed. I clicked sync, everything was the same. Where are my bookmarks and passwords?

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.

So I have had a favorite URL in Firefox for a decade or more https://www.outlook.com/owa to access outlook.com via web browser. Microsoft in Firefox only since the last upgrade does some weird looking and throws an error saying to try again later. If I delete my cookies for live.com and refresh the link it brings me to the sign in page where I can put in the email/password and it opens fine. If I close the window same thing happens and have to clear cookies, etc. Doesn't have the issue on Chrome or Edge, but thought I would make someone aware something odd is happening there. For now I just am using an alternate link https://outlook.live.com/mail/0/ and it comes up fine but it is not re authenticating again at that point.

Is there something I can do to avoid the error?
