I designed a label in Avery, downloaded as a PDF and told my download to always open in Adobe Acrobat Reader. When I try to open the download I'm told that Reader can't pen because it is either not a supported file type or the file has been damaged. How can I change the program that opens my downloads? I'm using latest Firefox on a Windows computer.

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

Hello! I am developing a web server, from which users can download large files. These files take a few seconds to generate, and cannot be generated ahead-of-time; only when a user requests them. The server therefore responds to such requests by first sending the HTTP response headers (without "Content-Length"), which can be written immediately, then generating the file, and sending the generated file as the response body.

In Chromium, this leads to the "Save As..." dialog appearing instantly, so the file can be generated & downloaded in the background while the user picks a location.

In Firefox (v132, linux x64), the "Save As..." dialog waits for the file to be generated before appearing, which is not user-friendly. During deeper testing, I discovered that Firefox appears to wait for my server to send at least 1 byte of data from the file (in the response body, after sending the HTTP response headers), before the "Save As..." dialog appears.

I have searched the Firefox settings and documentation but did not find anything that would explain this behavior. Is this a bug?

I have a few websites where I can download videos to view later. One of them downloads into the designated file but it shows up as an internet file (.html) and will not open or play as a video. What can I do to fix this without messing up the ones that work ?

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.

After downloading a file which is saved to my Mac Download Folder the file is removed once I close the Firefox Web window. I checked the folder before the window was closed and the file was there. After closing the window the file is no longer in the folder. Also it is not in the trash.

Hi, I'm running into an issue where when I download a CSV-file from a website it's downloading as a pdf when it should be downloading as a csv. If I after the download rename the file back to the csv-extension, I can open it in Excel. Any ideas? I run Linux on my laptop.

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

Download not adding a number to like files when saving. For instance (mycardexp.doc if I download the same named file tomorrow mycardexp.doc it use to add a number like mycardexp(1).doc FF has stopped adding the number showing that multiple files by the same name exist and how many.

Hi Guys,

FireFox keeps saving Torrent links to my Downloads folder even though I have set it to just open the links directly with my torrent client. This is super frustrating having to go into my downloads folder on a daily basis just to delete a laundry list of .torrent files. How do I get this crap to PERMANENTLY stop from downloading and just opening directly with my torrent client?

Mozilla (and this feature of Firefox forcibly downloading files to my drives after being specifically marked to be opened DIRECTLY), is just Mozilla and FireFox purposely & forcefully shortening the lifespan of my SSD's. By forcing these link files to be downloaded to my Downloads folder (filling it up with crap) which in turn is forcing me to constantly delete these (link files) is causing unnecessary extra wear on my SSD!! I live in South Africa where an SSD costs the same as 8 MONTHS worth of utilities (electricity and gas). So we tend not to look kindly on unnecessary wear and tear... especially if there is a function to minimize this but it simply doesn't work as it's supposed to.

Please give me a way to completely and permanently STOP FireFox from downloading these magnet links to my SSD or kindly recommend a better/different browser that doesn't do this.... just like the "old FireFox" didn't.

Thank you.

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 have set up a preferred download location in Settings and also ticked the "Always ask you where to save files" box, so for every download, the default location comes up in the download screen.

However, I regularly want to download a number of files in succession to the same non-default location and it is a pain to set it up each time. Is there any way to get Firefox to remember the last location used to save a file and offer it each time (at least in each session) for downloads?

I'm running Firefox 135.01 (64-bit) on Windows 11.

Many thanks.

Mike
