I have a 2008 iMac with El Capitan 10.11.6 ... Need to re-load my Firefox, but can't.

I realize that you all don't support the older version. Yet it's also the case that Apple won't update this El Capitan on my 2008 model (terrible, a crying shame, I know).

I've also tried to install your Extended Support Release. Will that work? I'm an independent research scholar, not currently associated with either Oxford or Stanford.

So I really need to have your Firefox back — I had it until this morning, when I needed to trash it (b/c of a bug), and then re-install. Yet I've not been able to re-install so far.

Hence, I'm seeking your help!

Thank you, Davy

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!

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'm using Firefox 78.0.2 and i keep getting notices to upgrade. But the last time I upgraded, Firefox changed the locations of my tabs from below the address bar to above the address bar and also changed the behavior of the address bar. It took me a couple of weeks to find the answers and get things back the way they were. I don't want to upgrade Firefox because I have no idea what it might change this time. Is there a way to keep Firefox from sending me upgrade notices when I don't want them?

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

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

Upgrade from V52.esr to V81 - no Logins imported, no Fix working

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?
