simply that except for the odd ocassion, I cannot download documetns generated by Copilot when i'm using firefox. I uninstalled Firefox and it worked on Edge but for a while and then i started having problems with that as well. For several months when i first started usin Copilot, it worked fine and then suddenly I started having problems.

Mac Tahoe 26.4. Any attempt to download or upload results in a file chooser/picker/browser panel that shows part of the finder interface but not all. Can't interact with it besides switching between sidebar items, no files visible, can't close or exit this window, can't interact with anything else. The only active button on the top of the window is the fullscreen button. Have to force quit firefox every time.

I tried troubleshoot mode and it did nothing. There is a workaround for some download links where I can open them in another tab and they automatically download without opening the window. Drag and drop options seem to work for uploads when they're available.

I took screenshots and was going to attach them, but this problem prevents me from doing that. This browser's sorta bricked for me at the moment.

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.

I had recently tried to download a .Zip file, which got corrupted. I tried twice again. Now every time I open the browser the three corrupted files pop up in the "downloads" window. It does not appear when opening a new tab, only when starting the browser. I have deleted the corrupted folders and don't want to retry downloading. I have tried both "clear all downloads" and "remove from history" in the downloads window, but the notification still shows up. Settings do not help.

How can I remove this pop-up? It blocks my toolbar and is a general nuisance.

As of today, every single time I try to download something, Firefox instantly cancels it and I'm not sure what the issue is. I've disabled adblock and Malwarebytes and refresh Firefox—same issue. Hitting retry from the download panel works but I can't figure out why the first download attempt is always cancelling, even if it's the same file. I'm not even downloading big files.

All of a sudden I can't download files from apps I use all the time... and download files from all the time. I just tried in Edge & I can download just fine. This just happened this morning. I downloaded multiple files yesterday within firefox & the same apps I'm running today.

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.

I am unable to download large files from an MS Sharepoint account in Firefox. Small files are fine (less than 100MB). Large files download fine if I use MS Edge browser but I don't want to have to use Edge unless absolutely necessary. Using Firefox Troubleshoot mode doesn't help. Clearing the cach/cookies etc doesn't help. When downloading a 600MB file, the download repeatably fails around 90-100MB. My OS is Linux Mint xfce64. Obviously MS doesn't like firefox for some reason, even in Troubleshoot mode. thanks in advance for any help.

My current version of Firefox is 149.0 (64 bit) Mozilla Firefox for Arch Linux Arch Linux - 1.0 I am running this on two computers, a laptop and a desktop, both running Arch Linux, currently at 6.19.10. I use the laptop much more, and recently noticed that I cannot upload or download files with Firefox. No file selection window opens and the request is simply ignored. Nothing appears in my Downloads folder. Meanwhile, I also noticed that this function works just fine on the desktop computer. I don't remember making any settings changes. I do have popups generally disabled but can enable them for certain sites. In any case, I have tried enabling popups and redirects completely with no change. I figure there must be something different about the settings on these two Firefox installations, but what? What can you tell me? Or ask me? Thanks.

1. This could be under-reported problem. People will have problems reporting this bug

2. Whenever I try to save anything (image, website, Ctrl+S, print website to file, Ctrl+P, screenshots, same problem) my Firefox tries to "Open" something instead. I see dialog window with header SAVE, but the final button is labeled "Open" and after clicking it usually nothing happens. A haven't been able to save anything since this update. Only system-wide screenshots work for me now.

I had to use another installation in order to attach screenshot here. In the problematic 149.0, after clicking "Browse..." and selecting file, nothing happens, and no upload, moreover button won't respond to clicking anymore. Then I force refresh, and this text within this form disappears, but attached image appears.

3. Yesterday I have updated my Firefox to 149.0, using official debian sources, mozilla-deb - 1.0 -

cat /etc/apt/sources.list.d/mozilla.list deb [signed-by=/etc/apt/keyrings/packages.mozilla.org.asc] https://packages.mozilla.org/apt/ mozilla main

4. I have Linux Debian, (old version, Stretch+backports, yes, I am moving things already to new hdd), maybe it's related: 4.9.0-19-amd64 #1 SMP Debian 4.9.320-2 (2022-06-30) x86_64 GNU/Linux )

In order to fill this form I am using separate installation 140.9.0esr (64-bit), you could warn Debian teams not to propagate this error.

5. I have checked Console and Debugger, but they seem website-related. This error happens on every single website. Tried already troubleshooting mode, same problem. Please help us.
