Firefox Support Forum

I have been trying to locate the temporary file of the failed download video file. I was downloading a huge video file (78 GB) and the system froze in the middle of it. So I was forced to cut the power and restart the laptop. After restarting, I saw that my system drive is still filled with the temporary file (part), but I couldn't locate it and delete the temp file. It has taken up about 40 GB of my system drive space because the download was more than half way through.

When I started the download, I selected an external drive as the destination. However, I have been observing Firefox download behavior and I am pretty sure Firefox would download as much of the file to system drive as possible, until the system drive is full, then moving onto the destination drive, which has been a huge inconvenience, because of the huge video files that I am dealing with.

I have already cleared the file and the .part in the destination drive, but failed to locate the rest of the temp file in my system drive. I have searched the internet and found no mention of such problem. So I am seeking professional help here.

Attached is a screenshot showing how much space is used by checking the system drive properties, against the properties of all files in system drive (including hidden). The number doesn't add up, and there are 52 GB of files unlocated.

I am running Firefox v. 94. I attempted to import my .csv passwords from chrome, but it failed. I also tried to use the Import from other browser option, but could not locate it in Firefox.

Hello, I keep having the same problem over and over again. That is getting a system error message which states "code execution cannot proceed because VCRUNTIME140.1.dll was not found." I have already uninstalled and reinstalled FF multiple times to no avail. I also deleted the program files as well. Thanks for any assistance screenshot available

I updated my OS X to 10.11.6 recently. Firefox is dead. I attempting to install an update as instructed on Mozilla. Does not work. I tried the “enterprise” version, too. It doesn’t work. Tried to recover via Time Machine - since it was system update that didn’t work, either. I’ve lost all my bookmarks. WHAT can I do? Sending using Safari 11.2 since FF is dead.

As the subject says, my download speeds are painfully slow (~200KB/s) and they have been for a while. My download speed is ~85Mbps and I use Ubuntu 20.04.

Installing a download manager extension only improved the speed to ~300KB/s (I tried Multithreaded Download Manager. I also tried increasing the number of threads in preferences to no effect).

The problem has persisted over time and across multiple restarts. This problem does not persist in other applications (Steam, for example).Neither disabling my VPN or running sudo UFW disable affected the speed (didn't restart because UFW disable doesn't require a restart [I think] and due to the above paragraph).

All solutions I have found have been related only to Windows users, hence why I am asking this even though there is a plethora of threads on this same issue. Any responses and help is appreciated!

I don't do this very often plus I'm fairly new to Win 10. I just bought a music album from the Amazon Music store. It is only available in Mp3 and downloaded as a .zip. And there it sits in my Downloaded folder. Please advise. Dick B.

Hope you are doing great work but I am facing a problem anyone can solve my problem. How do I repair Firefox installation?

I want to transfer a Firefox profile from my old computer to a new computer. The online info has been distinctly unhelpful. I copied the profile from my old computer put it in the Profiles folder on my new computer but FIREFOX does not notice it. What is the problem?

i wish there was a "Comments" section on https://www.mozilla.org/en-US/firefox/mac/ so i could tell people "NEVER use this!!"

i tried last week, downloaded and installed. The installation process, after unpacking the download, tried to install a "helper application". Popped up a dialog box asking for an admin userid+passwd. (even though i was obviously already running as an admin user... because i was in the middle of doing the install.) This was not an iOS dialog box from Apple, and it didn't have an option for scanning my fingerprint; this was something the "helper app" was doing on its own. Well i gave it my userid+password, and it went on to say the installation failed, and bombed out with no Firefox installed on my machine. Now, for all i know, my credentials are out there, God only knows where. So i had to go change my passwd on all of my machines.  :(

Mac 12.0.1 User here. While attempting to upgrade from 94.01 to 94.02(and now seriously wondering why) I clicked on the downloaded .dmg file to open it and I was informed that there was no app capable of doing so. Then just to be mean, the file name was changed from awholebunchofletters&#s.dmg to awholebunchofletters&#s.dmg.part

...and not by me.

Windows 10 - Lenovo Thinkpad X1 Carbon This fall after an update attempt, Firefox started trying to update every time it was started. Deleted Update files in Program Data. FF would restart normally one time. Update data files were always replaced and the update on every startup continued - over and over and over. Tried refreshing FF- same thing. Uninstalled FF this AM and tried to reinstall when I get the following error:

XULRunner Error: Platform version "94.0.2" is not compatible with minVersion >= 94.0.1 maxVersion <= 94.0.1

No FF - HELP!

I naively tried to update my Firefox software, but then when I tried to open it, I got a message saying my system is too old. I have OS X El Capitan Version 10.11.6. I gather you can download an older version of Firefox, but the directory is rather confusing, I don't know which option I need. Any help would be gratefully received, thank you!

Hi All,

formerly there was a "view release notes" button in the update reminder window to check whether the new release is worth the installation or not. This button disappeared several months ago. Is there a way to enable it in about:config? I think that asking about an update makes no point without showing the list of changes...

Thank you,

Gábor

Firefox has just done an automatic update, but has installed 91.3.2(32bit) on my 64bit Windows 10.

I was wondering why it decided on 32 bit? Should I upgrade to 64bit and how would I do that?

Thanks Jon

Using Firefox browser for iMac. Recently (10/10/2021) attempted to download .aax files from Audible.com. Files were unexpectedly converted to .mp4 files, making files unusable by iBooks. Conferred with Audible Tech support. Audible Tech confirmed that .aax files are the proper format and that they did not/do not make any format conversions on their end. Audible Tech then suggested trying download with Safari. Download (of .aax files with Safari) was successful and maintained proper (.aax) format. Audible Tech said that he had not encountered this issue before and that it seemed to him that the Firefox browser may be responsible for the unexpected conversion. In the past I have used Firefox many times to successfully download .aax files from Audible.com, most recent prior to this problem was on (9/11/2021). I am notifying you simply to advise that you may have a programing glitch within the download programing portion of the latest version of Firefox (ver. 93.0 - 64 bit) for iMac(s).
