Firefox Support Forum

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 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 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.

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?

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.

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.

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.

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 installed Firefox on a new windows laptop. Then I discovered there are two copies. How can I remove the duplicate without uninstalling both? The PC arrived with Windows 10 and I upgraded to ver 11.

Hello,

I've been having problems downloading the firefox browser, as it seems that I have to do it multiple times before it can be installed properly. I tend to get the disk image, which populates on my screen as an image icon. This usually occurs several times before I see the actual application file within my download files. Tonight I am having this problem again, as I noticed that the browser was no longer on my computer, which prompted me to download again from Mozilla's own site. However, I keep getting the disk image, with a circle and cross through the circle over the actual firefox icon which is supposed to be dragged into the folder and then installed. Not sure why it keeps showing up as an image (disk), and not the actual application? Any assistance will be greatly appreciated.

I completed the application to download Firefox but am unable to provide a backup device so could not complete. The alternative of Microsoft edge does not work.

Today I was forced to erase my hard disk and reinstate / reinstall the entire operating system on my MacBook Pro [from my back-up] ... in doing so I was upgraded to Firefox v94 [from Firefox v92] and all my bookmarks and folders and my reading list were lost ... btw I had no option, no alternative was offered ...

Is there some way of salvaging the bookmarks, folders and reading list from v92 and importing them to v94?

I thank you kindly in advance for your advice

I have used Firefox for a number of years. Something has changed on Windows 10 or Firefox. I am no longer able to download bank statements (multiple banks) to PDF for viewing and saving statements. I can do it on Microsoft Edge, so maybe Microsoft is trying to force move to Edge. I can't use Firefox if i cannot download files from internet to PDF documents. Tried looking at settings and can't figure out anything.
