Firefox Community Forum

When I download with this browser, I cannot open the file and it states download has "failed". Any other browser I use allows me to open the file. I use Firefox most often because I like the way it performs, but the download issue causes me to look elsewhere for a viable browser. I cannot seem to find what is causing the download failure and am hoping you can offer a reason that will provide a fairly quick fix.

hi, in my older laptop i have no problem downloading pdf files. Canva or webpages that open as pdf file. But in my new laptop i have idm downloader installed. download helper is also installed yet pdf file is not downloading. In canva it is not downloading at all. in case of pdf webpage the page is staying white with no action. What should i do. I searched web about this but never got an answer. even now i don't know if i explained the problem in a way you could understand

i can see the video detected but when i click on the blue download button it says sadly we failed at downloading that specific video. It does this for youtube videos no matter how many times i try it. i never had this problem before and it seemed to have started in may of 2026

Hello. I have a question regarding a problem with exporting files in Firefox. For about four days now, when I try to export files in Firefox, it fails. I've looked into it, but haven't been able to find a solution. Could you please give me some advice? I've tried various things within my capabilities, but nothing has worked. Firefox 150.0.1 64bit

Hello all.

For a while, all downloads have failed on Firefox (150.0.1), Windows 11. No file downloaded, and download tab shows a 'failed' underneath the file name. This holds true when downloading any file type, via firefox directly, or an outside app (Discord, for example) that hooks into the browser. Downloads work on other browsers (Chrome).

• I have checked about:config and reset the recommended options from other articles ("...lastDir" was the only one of the list that had an entry).
• Starting in Troubleshooting / Safe Mode does not fix.
• I currently run Norton - disabling it did not seem to fix.
• I don't have a Family group, so it's probably not the parental controls issue (though I think that was solved?)

I recognize that the lack of ability to download in Safe Mode points towards the possibility of an outside program blocking downloads, but I'm at a bit of a loss, since other browsers do work.

Thanks in advance for any ideas or suggestions.

Ever since 149.02 update Firefox has been unable to download any images automatically. They are always 'canceled'. I have to manually click RETRY button for it to work.

I have been through a ton of possibilities with Gemini, none of which worked. Apart form totally reset Firefox, which I refuse to do because WTF !

Gemini gave up and suggested I post something on here. I'll just switch to Brave until 149.03 fixes it.

Simple problem; complex solution? I work between two laptops and send files from one PC to the other by email. This week I could not download the sent files on Yahoo Mail. It literally just stopped downloading. I checked my security settings, created an exception for Yahoo Mail, double checked MS Defender, but nothing seems to be blocking it that I can see. I tried to review other sources, but could not find something for this situation. Help?

We run the www.rarlab.com website and several users have complained that the download of the exe file for the English version of WinRAR 7.20 downloads a 0mb file and is also flagged as malicious. The file can be downloaded easily on the Edge browser and it is considered safe by Google too.

This extension used to work fine for me on youtube but no longer does , it goes through the motions saying its downloading but the resulting file is a 0 bytes , rather than megabytes , ive tried downloading each files size 1080p 720p etc but the result is the same , at first i thought you done this so people would by the pro version but of course thats clearly not the case as no one would buy something is not working , so im not sure what the problem is i may reinstall it just to see if that works , im hoping youtube have caught on and blocking it somehow anyway thanks in advance
