I haven't changed anything in Firefox Browser settings. But when I open a bank statement, it is opening in the firefox browser, not in Acrobat. For years it opened in Acrobat. I checked Firefox Settings - Downloads for .pdf and it is still set to open them in Acrobat application. I have toggled the options, but still will not open in Acrobat. I have rebooted PC and tried again, still not opening the .pdf in Acrobat. Please advise what I should do Thank you

Dear Developer,

Please add an option in Settings to select a default external download manager (e.g. 1DM+, ADM, etc.) for all downloads. Currently, Firefox shows the "Download file with" chooser every time. It would be much more convenient if users could enable an "Always use selected external downloader" option, so downloads are sent directly to the chosen app without displaying the chooser each time. This would make downloading faster and provide a smoother user experience. Thank you for considering this feature.❤

I have personal files on rapidgator.net & premium account. if i try to download one of this files on firefox my speed is only 2-4Mb/s if i try to download with JDownloader the speed is 45-55Mb/s (one single file) This has been happening since October 2025...

Trying to download a QFX file to an account in my Quicken Classic file. I have done it 100's of times without issue. Now Firefox is downloading the file as a PDF not a QFX. How do I correct the error? Instead of the data from the bank downloading to my Quicken account, this shows on my screen. "PDF VIEWER PLUS SE" "CANNOT OPEN FILE C:/users/herb/downloads/transactions-68.qfx" How can I fix this?

When I drag a URL from the browser to the desktop, clicking on it triggers a prompt, saying "Do you want to open this file". If I look at the general tab in the properties of the link, it says "This file came from another computer and might be blocked to help protect this computer". This happens on both of my windows 10 computers since they upgraded to the latest version of Firefox (153.0.1.) I need to check the "unblock" option in the link properties to unblock the link. This does not occur with other browsers.

I have a new MacBook Pro M5, with MacOS Tahoe Version 26.5.2, and currently running Firefox 153.0. Over the past few days, I've noticed that the Fn-Delete (forward delete) is not working in the file name field when downloading a file from the internet. Fn-Delete is working everywhere else.

I'm not certain if this started when I set up the new computer, updated the MacOS or updated Firefox. I'm pretty sure all have occurred within the past couple weeks.

Thanks.

If I go to save something from within Firefox (on MacOS desktop browser), if I try to forward delete some characters, nothing happens. I can go to the address bar and forward delete characters within a URL, but doesn't appear that I can do so in other dialog boxes within Firefox. I've verified issue persists in debug mode as well as standard mode (and just re-freshed firefox within the last day and thought that had resolved the issue until realizeing forward delete will still work in URL field, but not in firefox dialog boxes like the save as window when downloading something.

I have windows 10. Every time I download a file and then go to open it, I get "File Download-Security Warning" this is new and never got that before. How do i eliminate the warning . This only happens when using Firefox..Chrome works fine. I have tried everything and changed more setting in the registry that i can count and have asked Perplexity and Grok plenty of questions with no positive results.

Hi, on my new PC with Windows 11 Firefox shows "save as" window after the download is complite. How can I change it so that this window appears before download starts?

Hi everyone,

I am currently using Firefox on Fedora (KDE Plasma) and looking for a way to automatically route downloaded files into specific folders based on their file extensions.

For example, if I download a '.stl' or '.blend' file, I want it to automatically go to '~/3d/downloaded', and if it is a '.gguf' file, it should go to '/models'.

Since native application settings only allow choosing one global download folder, using third-party browser extensions feels like a security risk as they require broad file system access(This concern might be unnecessary since I don't know how to decide an extension is safe or not.). On the other hand, running a background automation script (like inotify-tools) feels like an unnecessary workaround for a feature that could be native(I solved it via this method for now).

Is there a built-in way or a hidden config in about:config to achieve this by file type? If not, do you think it is worth opening a feature request on Mozilla Bugzilla for native file-extension-based download routing?

I run Win10, and Firefox recently updated. I use https://partners.titantv.com/default.aspx as a TV guide for my Hauppauge TV tuner card. When I click on a program I want the PC to record, I click the red dot, which creates a program.tvpi file in my Downloads folder (see image attached). Up until recently, this type of file was associated so that clicking the red dot would automatically put it into the Hauppauge recording queue. However, the latest Firefox upgrade took that association away. So, now I have to double-click the program.tvpi file in the Downloads folder to activate it. Is there a way to re-associate it? I tried right-clicking the red dot, but there's no choice. I didn't see it in the Firefox, Settings, General, Applications feature. Thank you for the help.

Dear Support,

I have a Bug (in my opinion), that if select Settings --> Downloads "Files and applications - Choose how Firefox handles downloaded files and content." e.g. for PDF -> open in Firefox (P1.png), and I click on a PDF-Link, the File opens in Firefox and is not downloaded (P2.png). In the Settings if I select the Action "Always ask" (P3.png), click on the PDF-Link and choose "Open with Firefox" (P4.png), the File get downloaded too (P5.png). So it is open with Firefox and save File? I think this Action is not wanted.

Kind Regards Tobias

Its REALLY annoying that I have to manually go to my downloads every time I download a pdf to move it to the correct folder. Especially when I already have Firefox set to "always ask" when downloading a file. I don't need EVERY thing I download to go to a specific folder. I sort things as I download them. Its just REALLY annoying that Google does this ONE thing so much better and Firefox used to allow me to save things wherever I wanted them every time I downloaded. Super freaking annoying.

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.
