Firefox Support Forum

I am running version 125.0.3 (64-bit) on Windows 11, and I can't check for updates and have to manually download each new version after given a popup telling me that the latest Firefox update couldn't be installed. I've tried restarting the computer, tried running the Mozilla Maintenance Service, and installing the latest updates for Firefox and Windows 11. Nothing I've tried has worked, and no other help article has helped me thus far.

I have Firefox 124.0.2 running on Windows 11. For some reason, I can't update Firefox. When I manually download the update file, it appears to run Ok, but the version doesn't change. If I go to settings and click on "Check for Updates" is comes back and says Failed to Check for Updates. How do I fix this?

Originally reported on April 11th /questions/1444593: I have Windows 11 and the Firefox 124.0.2 browser. I cannot update to the latest version of Firefox. I receive an error message "Failed to update". I've uninstalled and reinstalled the browser, ran the install utility selecting update, nothing seems to work. Please help

Hi,

There many extensions such as:

https://addons.mozilla.org/en-US/firefox/addon/search-on-imdb-context-menu/ that say when trying to install:

Installation aborted because the add-on appears to be corrupt.

I am using Firefox Developper Edition, with extensions.langpacks.signatures.required set to false.

This addon, after download, installs fine as a temporary addon.

How can I install it permanently?

Thanks.

My Browser keeps on telling me there is an update... I've updated, reinstalled the latest version and it still keeps giving a pop-up saying there is an update...

How do I get rid of these pop-ups???

I have two desktop icons for Firefox. Each opens to a different file. How do I clear the old file? What do I do about the message that Firefox can not update automatically? Where do I look to see Firefox file and see what date it is downloaded? If it is operational? Why is the same series of problems repeating daily?

Not sure if this is a new 'feature' post-update but it's damn annoying. I was busily transferring some photos that I'd taken on my phone over to Firefox on my Mac. Wasn't until I went to find them on the Mac where they would normally be and couldn't find them. Bit of digging, opening up the Download 'history' on Firefox and saw "File not downloaded: possible security risk".

I can see that I can disable this 'feature' but it seems to be a global "allow". Is there any way I can tell Firefox to allow any downloads from my devices on my network yet warn for potentially insecure downloads from the web?

TIA

Due to repeated issues over a week, I uninstalled Firefox days ago. Tried to Reinstall it repeatedly on same device several times. It was working before..BUT it keeps showing its downloaded on Settings but Firefox download page keeps showing "DOWNLOAD" Tried several times. Not my computer. Nothing works to resolve it.. Windows 11..

Hello, I've installed Firefox twice in the last couple of days (Windows 10 - I think) and I continue to receive messages that say I need to install the latest version.

Do you issue updates daily, or is there something wrong with my Firefox installation or is it something else?

Thank you.

It has been observed that when a user uses the Firefox browser and tries to download a DDD file, the file format is .pdf instead of .ddd. In the devtools, it was observed that the content-type is text/plain in the response to the request. I changed the content-type to application/octet-stream, but the error still persists

I have Windows 11 and Firefox 124.0.2. Firefox keeps asking to reinstall. I think it is because I keep getting the message that it fails to check for updates. I don't know if I have installed the Microsoft Firefox or the direct Mozilla Firefox downloaded. Maybe that is the problem, but I am not tech savvy. I have used Firefox for many years and like it. I am also too old (83) to deal with these problems. Help!

Hi! On the latest version Mozilla Firefox 125.0.1 when i download .docx files i get the message 'File not downloaded: Potential security risk.' I select Allow download and the file downloaded can't be opened.

Thanks!

Hello, I have problem with firefox. When I try download from facebook page files .docx, .xlsx (Microsoft Office) Firefox automatically download it as PDF and file is broken. I don't know how to repair this. Please help, it is very frustrating.

My job requires me to download and open files in new tabs consistently. However, when I download these files, I don't want the download panel to obscure my vision. Can I disable it?

I'm following a tutorial to install cinnamon desktop which includes Firefox snap on my Ubuntu LXD container, but the installation with snap fails. Does anyone know why it happens and how to fix it?

Anyone know if there is a way to import Google Chrome extensions into Firefox. I am moving over and want to make it easy. When I search all I get is bookmarks which I know how to do.

TIA!

I got a new computer so I created an acct and set all my open tabs and history to sync. It wasn't intuitive to my not techie brain, but found out how to open all the tabs on the new computer. However, they don't open in the same order (makes it almost useless when you have a lot of tabs), and the tabs don't have their associated history.

Is there some way to have Firefox open tabs and history in the same state on the new device?

Hi

If I click my way through https://www.mozilla.org/de/firefox/all/#product-desktop-release I get a different Link everytime. So as someon who wants to distribute Firefox on different PC's , I want to know: Are there any direct download links for the latest version? The best would be some links like Webex has for distribution (e.g. https://mozilla.org/firefox/windows/FirefoxInstaller.exe)

Thanks in advance Robin
