I got a new Lenovo Laptop and cant get Firefox to load a webpage. Here's what happens and what I've done 1. I install Firefox and during install get error below, VCRUNTIME140_1.dll Not Found. I then click OK and Firefox Installs but when I load it no webpages will come up just a black screen no indications it is even trying to load the page, no error message. It does nothing. Cant even open Google.com 2. I looked in MS forums and they say to install Visual C++. Did every x86 and X64 version I could find. Still have the problem even after uninstalling Firefox and reboot. 3 Have McAfee, and took Firefox off the Safe list then put it back on. 4. Went to try and find the file but can't on a reputable website. So I looked for this file on my Dell Laptop and Asus Desktop. Both have Firefox installed and it works fine. Get this, NONE of my other two computers have that exact file name anywhere. VCRUNTIME140_1.DLL! They have 140.DLL and a few other 140.dll with different variation but no 140_1.dll? So how does Firefox run on 2 other computers without this DLL but not on this new one? They are all Windows 10 Would appreciate any help. Seems to be a Firefox or Lenovo Issue just not sure. If anyone know how to get the DLL from MS let me know.

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.

Alright, basically I backed up my PC before I wiped it. Then decided to move from chrome to firefox. But there is an issue, I can't migrate my passwords because google chrome will not read my old LOGIN DATA file and refuses to create a CSV either. So basically I can't import about a decade worth of passwords into firefox because of a flaw in chrome's design, fantastic.

So I thought, well, surely if there are program that let you read SQL files (such as the LOGIN DATA file) if you have the password, firefox must be able to do this to right? Well no. Apparently not.

I am not sure if this is the correct place to formally request a QoL feature but I would really, REALLY, like to be able to import my passwords directly from chrome's LOGIN DATA file, I have the master password.

It was my mistake to back up my files thinking that would be enough, I should have known better and double checked if chrome could not read its own native files. But now im screwed. Help. Please.

Hi there,

How can I install Firefox on my Android device without GooglePlay?

Basically what I need is a safe place to download the apk

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.

I have just had to install thunderbird on a new PC, and the email setup system is causing serious crash errors (red boxes with lots of text and Stack Overflow programming bugs (the actual thing not the website) ). I want to try installing an older version of Thunderbird, specifically 78.13.0

And I can't. The thunderbird website only gives me the ability to download the new version 91 or nothing at all.

I can find possibly older versions of thunderbird from 3rd party websites but they look a little.... off and I don't fully trust their content,

But, Why on why can't Thunderbird offer historic downloads of previous versions for those that need them or those that want to explore if they work on our specific systems.

How do I download version 78.13 from a reliable source?

Awhile back [the question was asked], however the 'solution' is not what we are after here.

Once upon a time, there was a table with the Firefox downloads. And in previous versions. That is what I am looking for. I do not care, repeat, do not care, about the form input selecting 'latest' platform, etc.

Assuming also there is a method of downloading offline installers using tools like wget.

Thank you...

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.

Merry Christmas Everyone. I have been using thunderbird for email with windows 7 for several years, and it does exactly what I need. One thing I definitely need is my own folders for different incoming email. No problem with windows 7 but I cannot find how to make them with windows 11 (old laptop gave up - had to buy new one). Right click on existing default folders or email name does not offer the option. All folders is ticked, as is folder pane. Hope you can help. Thanks

I'm trying to import logins and passwords from my old computer to the new one. It showed up as a JSON file and I converted it to CSV, but can't load it onto Mozilla. The "how-to" article says the Import From Files option had a bug and now what can I do?

I have read probably 100 of your help topics and none of them seem to address my topic in plain english. I have used Thunderbird for years on a windows computer (currently windows 10, Tbird Ver 78.6.0) and I am trying to move my profile from my windows computer to a new Mac running Big Sur Ver 11.1. Thunderbird (for some unknown reason) actually created 4 different profiles on my windows machine (two under: users/alan/AppData/Local, and the same two profiles under users/alan/AppData/roaming) but I have figured out which profile that Thunderbird is using based upon the help/troubleshooting/profile folder/open folder (which happens to be one of the ones located under: users/alan/AppData/roaming) and it is 13.9GB. I copied this folder (and all included files) to a jump drive so that I could move it to my new Mac.

  I am new to Apple and know nothing about their operating system.  I downloaded Thunderbird from the Mozilla website and installed it according to their directions.  I finally found the default profile on my Mac that was created when I installed Thunderbird and I deleted it.  I copied my existing windows profile to the same location.  Now when I start Thunderbird I am greeted with a message that states: "Your Thunderbird profile cannot be loaded.  It may be missing or inaccessible."
  Obviously I have done something wrong.  Please direct me how to correct my problem -- it seems like this should be pretty simple, but I am lost.
  Thank you very much!!

Greetings.Every time I try to download any torrent file browser asks what program to use. I always press open with Mutorrent and press button use as default program but every time I try to download it alwas ask same.I try a lot of things and nothing seems to help. Very annoying because instead of one click you need to do it 3 times and wait a delay.

Anyone know if there is a way to import Google Chrome extensions into Firefox. I am moving over and want to make it easy. When I search all I get is bookmarks which I know how to do.

TIA!

I'm making this thread since the previous one was closed and provided no real solution, yet the result shows on the very top of Google. So I like to provide helpful information to others in my answer below.

I have a Win7 machine, and just bought a new Win10 desktop. I followed some instructions from a YouTube solution. From the Help>Troubleshoot>Profile Folder, I copied the profile folder (onto an external drive) and pasted it (from the external drive) onto the new OS(C:) as per instructions.

It did not work, I do not have all my bookmarks and extensions, etc. on the new Firefox browser I have installed on my new machine.

I don't know what to do now. All that was selected and overwritten is still selected on "This PC>OS(C:)" I was tempted to just delete all that shows selected...maybe not a good idea.

I really just wanted to migrate all my bookmarks, but doing the full profile folder seemed like a good idea at the time.... Help Mr. Wizard?!!

I would like to migrate my Outlook 2007 Mail environment on my laptop to Thunderbird. How can I get my mails, maps, contacts etc into Thunderbird. Are there methods and/or tool to perform this ?

I have a completely new profile and a new installation of Thunderbird 78.8.1 and it's great! See https://support.mozilla.org/en-US/questions/1327837 for how I got here. I now want to copy and paste my old address book to my new profile Previous help on this forum says that my old address book is in files abook.mab and history.mab but in my old profile these files are suffixed .bak (eg: abook.mab.bak) My new profile already has a few addresses - which I am happy to lose - but does not have any .bak files. For the address book it seems to have these: abook.sqlite abook.sqlite-shm abook.sqlite-wal

history.sqlite history.sqlite-shm history.sqlite-wal

Not a .mab (or .mab.bak) file to be seen.

Can I just copy and paste abook.mab.bak and history.mab.bak?

I was gifted an Amazon Fire Tablet to use for an upcoming hospital/rehab stay. I use Firefox on my desktop and Android phone and want to use it on my tablet, but the Amazon store doesn't have the app. Not sure I trust the Amazon Silk browser, but I may have no choice. I am not a tech savvy person! I don't know the difference between a bit, byte, or buttercup. If there is a way to install and use Firefox on my tablet, and sync with other devices, I would like to do so. Please explain how to do it as though you are talking to a 6 year old (who probably knows more about this stuff than I do, anyway). Thanks. rennylloyd

As in title, I'm trying to install on a new laptop. Have downloaded version 78.6.0

When I drop the .dmg into the app manager I get a message "The app is currently not available in your country or region". I'm in the UK.

Is this really a regional restriction, or an error because the version is not compatible with the Mac M1 OS?

Please help!
