When accessing Outlook (https://outlook.office.com) using Firefox ESR version 128.9.0 and attempting to download a file attached to an email, the string 'UTF-8' is automatically inserted at the beginning of the file name, which is causing issues. This phenomenon does not occur with other browsers such as Edge or Chrome.

Is there a way to solve this problem?

Hello!

 Since some days I have the problem that all files I download from outlook are accompanied by a preceding UTF-8 in the file name. This is not the case for e.g. google chrome. Can I fix this problem by myself, or is it a general problem of firefox 128.9esr (64-bit)?

how do I download video download helper to my Firefox browser? I'm in a cul de sac in your website. There's no button to push to get the add on.

Please help thank you john

Hello,

Can you please assist with the following download issue?

Firefox often, though not always, is very slow to download files, and when this occurs, I am unable to search by others tabs etc. I can download the same file using Edge on the same computer "instantaneously". Firefox returns to normal operation ~ 10 seconds after I cancel the download.

I unsuccessfully attempted to search for solutions.

Thanks and regards.

When I was previously using Firefox in Kubuntu 22.04, if I downloaded something I could go to the Downloads icon and click on the download and it would open in the desired application. After a failed upgrade to 24.04 I had to do a reinstall and now in Kubuntu 24.04, if I click on a downloaded file it will always bring up a window with "Open the file link with okular?" and the buttons Cancel and Open Link below. How do I go back to the previous way of it working?

I can't download ANYTHING on Firefox I've been tempted to switch to Chrome again because of this like why can I not download I don't THINK I did anything wrong either and it's really becoming frustrating I'm sorry

I am trying to download videos from a site that I newly subscribed to. The videos do stream perfectly. The files do not download as video files and will not open at all. When I click on the download link, there is no recognition of a download happening and when I check my files later I have an "internet" file showing with a title but without a video file extension and nothing will open. The file extension is ".html". I am following the step by step instructions from the site involved. Other sites videos are downloading as expected.

Does firefox need to be my default browser? Any suggestions how to remedy this without losing what is working? Are there plug-ins that can address this issue?

Thanks.

Hello, We use the following code (in a Dockerfile) to download the latest Firefox for testing.

curl -fsSL -o /tmp/firefox.tar.bz2 "https://download.mozilla.org/?product=firefox-latest-ssl&os=linux64&lang=en-US" && tar -C /tmp -xjf /tmp/firefox.tar.bz2 firefox

Starting with 135.0 the tar command fails with:

bzip2: (stdin) is not a bzip2 file.
tar: Child returned status 2
tar: Error is not recoverable: exiting now 

134.0.2 works: curl -fsSL -o /tmp/firefox.tar.bz2 "https://download.mozilla.org/?product=firefox-134.0.2....

A couple questions: - What has changed? Is there some other way we need to download and uncompress? - Is there any documentation of the supported query params for https://download.mozilla.org

Thanks, Paul

Hello,

I'm using Firefox on Manjaro. Usually I'm using dolphin but I've installed nemo too for having a second option if dolphin doesn't work. But after installing nemo the file management software when opening the folder where the file downloaded switched to dolphin. Where can I change it back to dolphin?

Firefox Version: 135.0 (64-Bit)

System Information: Operating System: Manjaro Linux KDE Plasma Version: 6.2.5 KDE Frameworks Version: 6.10.0 Qt Version: 6.8.1 Kernel Version: 6.12.11-1-MANJARO (64-bit) Graphics Platform: X11

Since i've switched defaults to Firefox, every time I 'Open Link' on a discord image, Firefox downloads the image immediately instead of simply opening the image in the browser.

I would like to disable the automatic downloading of the image and instead simply open the image in the browser. How do I make this happen?

Although I have checked "Always Ask" to specify my download location, duplicates are still being saved in "Downloads". I recently "upgraded" to Windows 11 but do not know if it is connected. FF version 138.0.3 (64-bit). How can I prevent this please?
