A few days ago Firefox automatically updated and destroyed all my logins and passwords and a huge amount beside. Yes, there was blurb about how to find them which involved a file which did not exist on my system and the whole was not comprehensible.

I did ask for help but got nothing

Somehow, the next day my system had gone back to the earlier setup. Now Firefox wants me to update AGAIN!

Given my experience how can I trust Firefox not to destroy my data?

How do I stop using beta?

I Googled about stopping using Firefox beta and transition to release version but none of the pages I found in this forum talks about an error message about user profile that only gives me the option to Create a New Profile (therefore losing all my add-ons, cookies, settings and everything) or Exit.

I tried manually googling "download Firefox" and downloaded the release version and after installing it, I get the warning message above. This thread here https://support.mozilla.org/en-US/questions/1224888 has a link to the rapid release version but I end up in the same warning message.

Since the beta will necessarily always be a newer version than a release version, how do I transition from beta to a release version but preserve all my settings, add-ons and everything if Firefox will tell me that it won't let me use my existing profile in an older version, the release version?

My motivation to leave the beta version is that Firefox started having a bug since 27-Oct-2020 in Google meetings where either a shared screen or the camera image of the person in a meeting appears very zoomed in in the top left corner so it doesn't show the rest of the image.

Unable to import saved firefox profile (from windows 7 32-bit, to windows 10 64-bit) - new profile has none of my data

My attempt at transferring profile from an existing machine to a new machine has not produced the intended result, and I need help.

I saved my firefox profile (on a 32-bit windows 7 machine; firefox was fully up to date) without firefox running, in a ZIP file (the letter number combination followed by dot followed by default), then copied the ZIP file to the new machine (windows 10 64-bit), unzipped it (so I had the same file name as from the old machine), then copied this folder into position at

C:\users\user\appdata\roaming\mozilla\firefox\profiles

I then started firefox on the new machine, went to about:profiles, created new profile, selected the folder (which was present at this step), then completed the procedure and started a new firefox with the new profile (the option given in about:profiles).

The new instance of firefox has none of my data (several thousand bookmarks, passwords, etc.); instead looks like the other (default new) profile.

The existing profile file set was (after this procedure) visible in

C:\users\user\appdata\local\mozilla\firefox\profiles

The restored profile is running now as "Default User" and reflects the folder I transferred from the old machine (except that I changed the word "default" in that folder to "main", leaving the number-letter part and the dot unchanged.)

No errors were indicated from firefox (which is running version 83 now) during any steps of the old back-up/archive save step or the new restore/recover step.

What am I doing wrong? How can I recover my existing profile data? The procedure, while not very friendly, seems straightforward enough. I don't want to go into the details of recovering specific database files/folders; I'd just like the profile I had before functioning in the new machine.

Please help

Dear community, for some days my Firefox 80 on Windows 10 has shown the message "your system administrator has deactivated updates", when I look under "Help" -> "about Firefox". This is strange, because the admin is me myself, and I didn´t change anything in Firefox or in the Win 10 registry. Has anyone of you had this experience, and how can I possibly fix it? Thanks in advance! Pete

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

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.

My present iMac is failing rapidly and I will be replacing it with a new Mac very. I do not have a Time Machine backup. The only info I really need is how to copy off, to an external drive, all the bookmarks and bookmark structure), extensions, and add-ons I have added to Firefox, and then add them to Firefox on my future Mac.

Do I just copy the Firefox app to the external drive? I looked in the Macs' base system Library and Preferences, and in my User files, but I do not see anything related to Firefox.

My old (current) and failing Mac is running the latest version of Catalina,

Thanks for any info!

A few days ago my electronic certificates have disappeared from the firefox container The certificate provider has vetoed me from delivering a new certificate, because it is the second time Firefox has lost a certificate in 2020. The certificates I need for any management before the administration of Spain and more now with the COVID After it is granted, you have to verify your identity with the Tax Agency, and they have already called my attention for renewing the same year a certificate that firefox loses when it is updated. I'm very, very pissed off I will have to switch to Chrome

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,

Just a suggestion on getting update content information.

I do not enable automatic updates in order to maintain personal update control and to generally wait a few days to allow any bugs in the update to shake out [e.g 81.0.2 to fix the Twitter bug in 81.0.1 -- No biggie, small bugs can crop-up in any update in spite of Mozilla's commendable quality control]. When manually checking Firefox "About" to look at update status, the pop-up shows the current installed version, with a link to "What's new?" [Great idea, thanks]. Unfortunately, there is not a "What's new?" link beside the box to download a new update, thus one must do an on-line search for the related Release Note to determine the urgency/relevancy of doing the update.

Adding an additional "What's new?" would be an appreciated change -- Thanks and be well.
