Firefox コミュニティフォーラム

For reasons that are not clear, a few days ago, Firefox would not download any files — giving a failure message. I have tried all the different ways of resetting, disabling extensions etc, and even deleting Firefox and re-installing, but that has not solved the problem. Help!

I'd been trying to download 2 large files from Icann and kept getting premature completion with Firefox. It would be showing ##MB of 356MB downloaded for a few seconds and then out of the blues it just says completed. As you can see in the shared video, I've tried this several times.

I thought that maybe one of the Firefox addons was causing the issue so I tried Troubleshoot Mode but that resulted in the same behavior.

I then went into Firefox Profile Manager and created a new profile. But that too had the same behavior - 🤔!

So I then tried Chromium. It completed the download successfully and the file passed gunzip test.

So, why is Firefox, even with a new profile, failing to complete a download?

Beforehand, I must say that I am a big fan of Firefox, I've been an user since the beginning. However, sadly I am switching to Safari due to the fact that I work with file transfers through Wetransfer platform and fro some unknown reason I get incomplete downloads from Firefox. I tried all the steps and procedures to refresh, uninstall, reinstall, troubleshoot mode and even switching accounts. Furthermore, nothing worked. I hope you guys can fix this issue and have me back. I'll be delighted. Thank you and until next time!

Hello! I'm trying to download a quantity of audio files from a specific website. Once I open firefox, I can manage to download a few in that session - anywhere from 1 to 10 usually. Then, at some point, the downloads start to hang. They appear as how they do when they're loading - "Unknown time left - 0 bytes (0 bytes/sec)". However, they never load. The only solution is to restart Firefox, to be able to download a few more.

I'm on Linux mint, Firefox version 137.0.2 (64-bit). I tried running firefox through the terminal to see if anything would show up when the downloads stop working, and I got this:

[GFX1-]: RenderCompositorSWGL failed mapping default framebuffer, no dt [Child 47831, Main Thread] WARNING: Unable to open /var/lib/flatpak/exports/share/dconf/profile/user: Permission denied: 'glib warning', file /builds/worker/checkouts/gecko/toolkit/xre/nsSigHandlers.cpp:201

And a lot of "ATTENTION: default value of option mesa_glthread overridden by environment." - but those seem to happen all the time during regular usage.

Any way I can go about troubleshooting this, or am I stuck with restarting Firefox every few files I need to download? Thank you in advance for any help or advice.

Please tell me how I can download two tickets I just bought for April 23 for a church in Paris. I get this message: "Check that Firefox has permission to access the web (you might be connected but behind a firewall)". What do I do next?

Trying to download a zip file to be able to move forward with this job offer with Turbo tax and it will not let me. Need to find & remove the problem they said. I have no tech experience. Please help.

I access google drive through Mozilla Firefox and also zip file or other file download but since 1 to 2 weeks i faced issue to download files especially js file.How can I solve this?

My downloads keep failing every time. I tried everything from this list but all I get is download failed, this has been an issue for years. I have to press the try again button about 3000 times for it to slowly download a bit by bit but for larger files its impossible.

For quite a while now, whenever I try to save a file or image, if I attempt to change the folder for the download I get the error message "The Windows file-dialog has crashed." I think several months ago, Firefox would crash, but now Firefox keeps running but I get that error message. If I want to upload a file the same thing happens, which is a little harder to work around -- I try to change to the folder with the desired file(s) and the file-dialog crashes. The same thing does not happen with other programs -- I recently used Chrome to upload some files when I couldn't with Firefox. I have tried several fixes I found online, including Troubleshoot Mode and Refresh Firefox, but to no avail. I sure would like to find a fix...

I am using Windows 11 and Firefox 135.0.1 (64-bit).
