I was cleaning out my hard drive and deleting old installs of Microsoft Visual Studio Redistributable packages, and I almost certainly deleted the one that Firefox relies on.

I then attempted to start Firefox, getting the error, "The code execution cannot proceed because VCRUNTIME140_1.dll was not found. Reinstalling the program may fix this problem."

I uninstalled, following the clean install directions, and deleting the "Program Files/Mozilla Firefox/" directory.

Then, I ran the Firefox Installer, newly downloaded, and when running it, it gives the same error, "The code execution cannot proceed because VCRUNTIME140_1.dll was not found. Reinstalling the program may fix this problem." Selecting "Restore Defaults" has no effect either way. The installer then appears to complete in the background, and the Firefox directory is created, along with the executable.

When I run Firefox.exe, it seems to load the program, but any address I type in fails to begin loading. This includes websites (www.google.com) and help/utility pages (about:config). I'm therefore unable to change any settings within Firefox.

I then tried re-installing the "Visual C++ 2008" and "Visual C++ 2015-2019" packages in an attempt to restore that DLL, but that had no effect after repeating the same steps above (clean uninstall, re-install). Which VC++ Redist Package should I be re-installing? Ideally, I should be able to just get a copy of VCRUNTIME140_1.dll and place it where Firefox is looking for it.

I am using Firefox Nightly. It receives updates every day, but most of the time I cannot restart Firefox as soon as update is available. I want to delay it till next natural restart (ex.: night), however, Firefox shows notification about the available update. It's a minor issue, but seeing notification every day and having it to close every time gets annoying very quickly. I want to disable update notification but keep automatic updates. How can I do this?

Hello,I have Windows XP 32 bit with service pack 3 and Firefox 52.9.1 ESR browser. Now that adobe flash player is history I can't play videos online that are not on youtube. I can still watch youtube videos.

Is there a HTML5 video player or something else I can install on this old system that will work or is that not possible? I know it's an old system but it still does the job.

Thanks.

I recently installed an SSD with a new install of Windows and Firefox. I still have the old hard drive with Windows and Firefox installed on it in the same computer. I am trying to transfer the data (like passwords, bookmarks and other stuff like that) from the old versions to the new versions, but am having troubles finding how.

How do I get the new Firefox to look at the old hard drive to find the data?

I am currently on Firefox 84.0 on Windows 10.

Every time I download any type of file, Firefox puts the file inside of (C:) > Users > tmmor > AppData > Local > Temp. This is extremely frustrating because I have to manually move the files to my 'Downloads' folder every time I download a new file. I have changed my settings numerous times. In Options > General > Files and applications. I have selected the "Save files to" and I have changed it to many different locations and my files still end up in (C:) > Users > tmmor > AppData > Local >Temp. I have even resorted to selecting the setting "Always ask you where to save files." After closing and reopening the browser, I try to download something and Firefox never prompts me to select a download location (Contrary to my settings). Firefox just automatically downloads the file and puts it in (C:) > Users > tmmor > AppData > Local > Temp.

After looking for solutions online I have went into "about:config" and I found out that "browser.download.dir" was already set to "C:\Users\tmmor\Downloads" (My intended location) and "browser.download.lastDir" was already set to the same location. I have also set "browser.download.useDownloadsDir" from false to true. Firefox still puts my downloads into (C:) > Users > tmmor > AppData > Local > Temp.

I am also the administrator on my device. I am not aware of any windows settings that are blocking Firefox from putting my downloads into my "Downloads" folder. Microsoft Edge and Google Chrome put my downloads into my "Downloads" folder every single time I download something, why cant Firefox do the same?

I also do not believe that any of my extensions or plug-in's are causing this issue, I have very few extensions and plug-in's.

Firefox is persistent at saving my downloads to (C:) > Users > tmmor > AppData > Local > Temp. I have never gotten Firefox to save my downloads to my intended location (The downloads folder). Can anyone please instruct me how to resolve this issue. This is my last resort to solving this problem, nothing has worked for me. Thank you for your time, this experience has been stressful for me.

Hi,

I am an old-timer and one update per one or two years is enough. Are automatic updates at last disabled in firefox 88 ? I tried about:config but it is too much complicated, I am nearly retired.

Perhaps could you deliver forefix, the nice-to-have version of firefox that don't bother with updates.

For unfortunate reasons too tedious and mundane to discuss here, I am stuck with Mac/OS 10.11.6. I am looking for a version of Firefox that will run under that version of Mac/OS. I did the basic research and was directed Firefox version 78. After that, I was directed to the Extended Support Release. When I downloaded and ran that, I was directed to the Apple App Store where no version of Firefox could be found. Where to next?

Can someone offer me a link to a version of Firefox that I can download and run on Mac/OS 10.11.6? Please.

Hello community, would anyone kindly help me with this issue I'm facing? How do I export Logins and Passwords on Firefox running 78.10.1esr (64-bit) on a Mac. The export funtion is not available here and I know the this option is only available on 79 and after, but I'm using a mid 2012 Mac Pro running 78.10.1esr. Is there any way I could still export the logins?

Thank you kindly.

I shut down my PC without closing the Firefox brower tabs and I started getting this message the next time I re-booted and tried to start Firefox. --- "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window." ---

I read thru the different support forums and tried various answers/suggestions - no luck. Bottom line, I have uninstalled the browser, deleted all the old Mozilla folders from the machine and downloaded the .exe to try to re-install the browser. However, the installation crashes at about 70% completion and I still get the message listed above. I am running on Windows 10 and the PC is up to date with all patches.

I would appreciate if anyone can help me figure this issue out.

Hi, I want to move Firefox to a new PC. I know there are many guides on how to do that, but what I'm most concerned about are my open windows and Tabs. How do I preserve those on the move?

Thank you.

Background: I'm currently tutoring full-time, and the site I use allows tutors to download the session afterward as a .zip folder. In the past this has been incredibly helpful, because it allows me to review my lessons and improve my planning.

Current Issue: For some reason Firefox now appears to be misinterpreting these ZIP files as PDFs. When I begin the download, Firefox gives me the option to either open (as PDF) in Firefox, or to download. At this point (before any download occurs) Firefox has already labeled the file as a PDF. If I open it in Firefox, obviously it doesn't work (being a .zip folder.) If I download it, Windows Explorer usually lets me explore it as a .zip folder, but recently, about 10% of the files I download (even if I never open them as a PDF) still download as a PDF and are therefore inaccessible.

Fixes: I've tried downloading instead of opening with Firefox. This works about 90-95% of the time; not sure what the issue is. I've tried re-assigning the file type in Windows Explorer, to no avail. I've adjusted Firefox preferences (from "always ask" to "use Windows Explorer.") I'm not sure this will help, but will try.

Any advice? I hate to sound fussy, but I'm pretty meticulous about saving my lessons and hate losing that much data on my students. While I can save each file independently, it takes much longer. Thank you!

Hi Team,

I want to disable to "You have chosen to open this file" dialog for zip files but i am not able to disable it.

I have looked for some solution in google search that did not help.

Please help me on this.

I'm trying to import my saved logins and passwords from Chrome to Firefox. When to try to do this I get prompted to create a Primary Password. Whenever I try to do this, I get a message saying, "Unable to set Primary Password." I also can't cancel out of this or switch to another tab--I have to ctrl-alt-del and close Firefox to get out of it. I also can't create a Primary Password through the options menu. Anytime I try to set a primary password it just says "Unable to change Primary Password."

Does anyone have experience with this phenomenon:

When you click on a torrent link on a page opened in Firefox 83 (and above), the first window pops up, but the second one (in which uTorrent would come) is no longer. Nothing happens. Specifically, the entry is C: \ ProgramData \ Microsoft \ Windows \ WER \ ReportArchive \ AppCrash_uTorrent.exe....

If I revert to Firefox 82 or 78.6esr, the error will not occur.

If I choose not to download uTorrent but to download the torrent file, it works fine with all versions of Firefox.

Firefox just updated, without my permission, which is another problem. But now when i try to open pdf files, firefox always ask what to do. In Options > General > Appliacations i set pdf files to open with firefox, but firefox still asks what to do. In the window where it asks what to do, there is a tick box saying "Do this automatically from now on", even if i choose that option it still ends up asking what to do the next time i open a pdf file.

Read support article about importing username and password info direct from .CSV file. I see at the bottom of that article that if no such option presents (Import from file), I am to ensure that signon.management.page.fileImport.enabled is set to true. I don't see that operator within the listing of configuration options. I can create that operator and set it to true, but that doesn't make the 'import from file' option appear in the three dot drop down menu within the Logins and Passwords page. Has the title or location of the fileImport operator changed, been moved?
