Diễn đàn hỗ trợ Firefox

Earlier I logged in to Firefox to pose a question. Checking email, I had a notice from Mozilla that my account was used to sign in: Firefox on Windows 10 / United States (estimated) / Thursday, Oct 23, 2025.

Does Firefox think I'm using Win 10??? I checked my computer and it verifies that I am running Win 11 with all updates.

Call me confused. Or is this a non-issue? I ask because I'm trying to get into a member website and after I login, it takes me to a page that is for new signers ... not an existing member. Has happened several times.

Thanks,

Ron

When I try to open a pdf on a certain site I get the pdf, but there is an overlay of a pencil editing a ghost document. How can i get rid of this overlay? I've tried everything.

I asked this same question yesterday and a little while later, the horizontal bookmarks toolbar "magically" appeared. Now the toolbar is gone again. How can I find it and get it to stay at the top of my page? (I'm an 80-year-old granny/computer-dummy.) Thanks in advance for any help.

I have Firefox installed on both my desktop and my laptop. On my laptop, I am able to create and manage profiles; however, on my desktop, there is no option available in the menu (the hamburger menu) to do so.

I have verified that both devices are running the latest version of Firefox, which includes the profile management feature, but I am still unable to access it on my desktop.

I am reopening the question from 2020 as the solution described no longer seems to apply. https://support.mozilla.org/en-US/questions/1284577

I am running Windows 11. Firefox 144.0 (64-bit)

When entering search terms into the search bar in the centre of the page, the information typed appears in the address bar, even after following the fix described in 1284577.

Treating the address bar as the search bar appears to be the default. While the user can additionally deselect the search engine in the address bar, that is an unnecessary and undesired additional step for every search (the primary reason I am using Firefox)

Is there a way to permanently set the default for what I enter into the search bar to remain in the search bar and not to be managed by the address bar? Thanks, Rich

Hello, I have Facebook Container installed (Windows 11) on my desktop. However, if I click a link to a FB page, say in an email or on a webpage, Facebook opens onto the current tab and makes it a container tab. Since I can not go back once FB is opened in the container tab, I have to open a new tab and go back to the original (pre FB) webpage. This is the only time this happens.

What settings can I change so that the Facebook Container opens Facebook into a new tab, not on top of an existing open tab?

Many thanks for the millions of us that are computer challenged.

I'm running the current version (144.0, 64-bit) on a Dell Inspiron laptop. Just now, I tried to save a bookmark, but I found that a goodly number (not all) of my bookmark folders had disappeared. When I tried to restore from a Firefox backup, I got an "Unable to process file" message. What's wrong , how do I fix it, and how do I get the missing bookmarks back?

I attempted to put in an address of what I thought was a website today on mozilla. I soon found out that it was not available or a proper website.

Now I am getting alarming notices with heading Mozilla Firefox all via what looks like an Indian website, saying 1. Click to secure your 2. Trojan detected Fix it now. 3. Critical Error. Click here to remove them.

I have not clicked on any part apart from the x top right to remove the notifications. I can send photos of them

I have scanned with my Windows Security repeatedly and nothing.

PS. The messages are obstinate to remove and it takes effort to x them.

The layout of YouTube was different from before. In the past, after the YouTube video was over. The MAIN WINDOW within YouTube page would showed two rows of recommendations. Now there is only one row with great amount of black-out space at top and bottom. Any suggestion to tune it to the usual two rows?

Starting on October 18, I've had problems accessing most websites. I get security errors such as:

Secure Connection Failed Error code: SSL_ERROR_RX_RECORD_TOO_LONG

Secure Connection Failed Error code: PR_END_OF_FILE_ERROR

This problem occurs only with Firefox. It doesn't happen with Chrome (which I had to use to post here).

A few sites work, but not many.

I tried reinstalling the latest version of Firefox but that didn't make any difference.

Suggestions? Thanks in advance.

Hello,

I use a Powershell script to manually install a Firefox update.

Starting with version 128.10.xx and higher, Update.exe expects different parameters, but I'm not sure what the parameter names mean (see screenshot).

Can someone explain to me what I need to pass for “arg-version” and “wich-invocation”? All other parameters were already present in the previous version of Update.exe, and I understand those, but unfortunately I don't know exactly what I need to pass for these two.

Thank you very much in advance for any help.

What do I do to solve this - I get this when I 'try' to game in Facebok: "Sorry, your browser does not support this feature. Please use a different browser and try again."

Please tell me how to resolve this issue. The 3 reports I have submitted from the crash window are:

Hi, All of a sudden, I lost absolutely all of my bookmarks. My PC is running Windows 11. My Firefox account was and still is logged in. At first, I thought the data loss was due to a CCleaner cleanup using their latest update. After the data was lost, I tried running another CCleaner cleanup, but this time it didn’t delete the bookmarks. So I honestly have no idea how this could have happened. These were bookmarks I had saved over many years... It’s a disaster.
