Firefox Forum di supporto

I uninstalled Libre Office and it apparently uninstalled the VCRUNTIME140_1.dll file s part of its uninstall process. From this point Firefox would open but would not connect to the Internet, either by clicking one of the links in the toolbar or typing the address directly. I have tried all the solutions I can find on the support pages, ranging from attempting to copy the file from another location to re-installing Visual C++ from the Microsoft website, both the 64 bit and the x86 versions. Having found and installed the latest version of Visual C++ I now get the error message "The procedure entry point _CxxFramehandler4 could not be located in the dynamic link library C\WINDOWS\SYSTEM32\MSVCP140.dll" at the edn of the installation process, and of course Firefox has not installed. Any suggestions for a way forward?

Hello, I just restarted my PC after a Windows 10 update (Windows Update). Launching Firefox from the task bar no longer worked (link removed). So I launched Firefox from the start menu. A completely blank version of Firefox appeared on the screen, as if I had just installed it. No more favorites, no more extensions, no more customization. All Firefox installation files in the AppData directory are dated today. How can a Windows update remove a Firefox installation? Is it possible to recover favorites and bookmarks? Thank you for your answers. Regards,

I continue too download but cannot see how too use this

i am getting message from "performstrongintenselyapplication.icu" saying "important Firefox update available". Is this legitimate? ABOUT FIREFOX says I'm already using the most recent version (81.0.1, 64 bit)

I'm trying to upgrade from V52 ESR - kept for known and obvious reasons concerning addons compatibility - to a current V81. Copied the profile data from user/appdata/mozilla/firefox.../myprofile/*.* - including "key3.db" (in use), "key4.db" (don't know where this one originates from - shouldn't exist at all for versions < 57 or so) and "logins.json".

So far stumbled upon:

• No Logins in new system visible. No master password set. After setting a new master password, still no logins visible.
• This very forum here suggests - in many threads for version upgrades from somewhere in the 50s to up to the 70s - to simply copy the "key3.db" and "logins.json" and to delete the "key4.db" on the new system's profile. That does not change anything at all.

Am i forced to keep the V52, now not only by means of addons compatibility, but also by means of login manager compatibility?

What would the correct path to upgrade be? Would i have to install each and every in-between-version from 52 to 81 to be able to migrate? Will i run into the exact same trouble doing it that way, only burning daytime for nothing? Or is it guarantied to somehow get the logins data transfered to the current version? How did all the Millions of other users fare with that aspect? Is that an extremely rare case where users set a master password, so that developers decided to not care anymore about those nasty paranoids?

Trying to install Firefox browser in a different location. FireFox version 8.2 for Win 10 does not provide a dialogue box to select a different location. What am I missing?

Ok, thanks, finally human help! I just had to change my pc and make a fresh install of the operating system. I used Linux mint on the last pc, and have Linux MX 18.3 on the new one, currently in use. I took the precaution of copying my Firefox and Thunderbird folders from the old hard drive, as I have several years worth of bookmarks organised in to folders, irreplaceable. This was the way I had preserved that information in previous changes, and swapping the old folders with those in a new install worked fine. But now i find the new version has changed and the files differ and cannot therefore be swapped. I don't really want to get into blaming or how disappointed and annoyed I am, as this won't be the fault of the person helping, and that is appreciated. But back ups need to be backwards compatible or there is no point? So, not sure which version I had, but will have been a couple of years old with updates. In my 'etc' folder there was a Firefox folder, and in that I have a folder marked pref. In that folder there is a file named apturl.js and I have saved those folders. With my new install there is not even a folder for 'firefox' in my 'etc' folder. How do I proceed to restore my bookmarks? If I need to install and older Firefox version I will do so. Many thanks, Tony

I wanted to go back to 80 because I didn't like 81. When I dl'd & installed 80, it told me that I had to make a new profile, otherwise my bookmarks might be corrupted. I did that, but now all my bookmarks & extensions are gone. Help!!!

Reading the several comments on this subject has not led to a solution. The Firefox Setup 81 and Installer are sitting in the downloads file, but when I click either "Open" or "Run as Administrator" I get a Windows "For security and performance Windows 10 in S mode...." followed by two options "Learn more" or "Switch out of S mode". When I choose the latter the "Switch out of S mode" page arrives. Now what? Thanks.

I've just set up a brand new profile and copied all my important user data across, including the bookmarks (places.sqlite).

But now my bookmarks have no icons?

I have over 25,000 bookmarks so I don't want to have to load them all in order to get the icons back!

Hi

I've just uninstalled Firefox as I somehow managed to have the beta version and the constant upgrades were driving me nuts. I now have 81.0 main version for Windows 10 64-bit. For many years I have kept my Profile folder on the D: drive for backup purposes. Having downgraded (by one version?) it won't let me use the old profile. Normally if I rebuild a PC or migrate, I edit %APPDATA%\Mozilla\Firefox\profiles.ini and point it to the profile on the D: drive but now I just get told to either create a new profile or exit.

How can I retrieve all my bookmarks, passwords and other preferences from my old profile?

Thanks John

I have kept FF v. 56.0.2 because of certain add-ons that I have come to rely upon. That version is shared by all users. However, I would like to add the newest version for a second user. How can I install the current version for only the second user without affecting v 56.0.2 for the primary user?

Reinstalled Firefox, still won't launch. Error message reads: Firefox can’t find the file at jar:file:///C:/Program Files/Mozilla Firefox/browser/omni.ja!/chrome/en-US/locale/branding/browserconfig.properties. Now what???
