Firefox Support Forum

I suffered a catastrophic crash and had to replace my computer, a mac. I replaced it with another mac.

Because the older one will not boot up, I could not migrate my firefox data.

I ended up doing 'lost password' for all my sites.

There are a couple where the lost password thing hasn't worked.

It occurred to me to rename the (new computer's) logins.json file, copy the old computer's logins.json file from my external backup drive, put it in new computer's /user/library/application support/firefox, and then look in preferences, get the two passwords I want, set things back, enter these passwords into firefox again.

This did not work. In fact, now no matter which file is named logins.json, preferences says I have NO passwords stored.

I cannot find anything that tells me how to just decrypt the .json files (at least, not in a step-by-step way that I can use.)

Since about two months ago, I haven't been able to update Firefox(or any other browser for that matter). I've tried the typical method of going to Preferences, checking for updates, but I can't get passed that point. I get this error message stating "Failed to check for updates."

Chrome was giving me much of the same issue, I've allowed GoogleUpdate on my firewall rules, restarted the PC and tried again. Still got the same error message. I have no other antivirus software installed on this device other than the Windows Defender default app. Firefox hasn't told what I should be allowing past my firewall so I haven't tried anything similar for Firefox.

I also tried uninstalling Firefox, but when I tried to reinstall, I couldn't finish that process because clicking on Download Now led me to this error message stating "Hmm. We’re having trouble finding that site.

We can’t connect to the server at download.mozilla.org."

I assumed this was maybe a DNS issue. I tried a DNS flush but that also was ineffective. I tried changing my DNS servers to 1.1.1.1 and 1.1.1.2, also tried other known DNS servers but that didn't work either.

In the meantime, I'd like to at least get an offline installer going because my current version is 110.0.1.

Thank you.

I am having trouble to open firefox browser for ubuntu 20.04(focal). I have also delete mozilla folder from cache and then reinstalled again. I have tried to rename profileini file. Finally I have uninstall and install using terminal by "sudo apt install firefox" but still I am getting this error "Your Firefox profile cannot be loaded. It may be missing or inaccessible".

How to resolve this.

Thanks in advance.

I have Dlink web cams. They are only accessable via a MyDlink app. The app is only compatible with Firefox 51 or 52. How do i get older versions running on my laptop?

Tell me how to "re" install my previous version of 113.02 and then fix this bug. Don't know where to get "old" versions to download and will old version just "install" right over the version installed and keep all the bookmarks, etc.?

I received a message from Fire Fox that I should update. Now I have 2 Fire Fox icons and I need to know how to determine which one to delete. Then I need to know how to transfer my favorites and history to the one I keep. They both show favorites and history. I'm a rookie at this so if you can explain step by step it would help, thanks.

I am using Version 113.0.2 (64-bit) and trying to access a home camera system, mydlink.com. When I go to log in there, it tells me "You are using an unsupported browse.....We recommend you use Firefox 12-51/52 ESR on Windows" Can I get this version? What options do I have? Thanks, Ed Corcoran

I have downloaded Firefox 113.0.1 for Windows x64 but the file seems to be corrupt. When I check the installation file with 7Zip Test Archive appeared a Warning Message due to a Checksum error. All others versions of Firefox downloaded can be checked correctly by 7Zip, but this installation file show an error message that I never have received. Is there a problem with the file? Thanks

HI, I had a PC crash and I am now unable to use my old Installation, so I reinstalled Windows anew. Before that I could save some stuff.

I have saved the whole Firefox Profile Folder and the Installation.

Now I just copied the Key3 and Key4 + logins.json Files to my new Profile Folder (places, booksmarks, etc too) but nothing will be applied.

What do I have to do to get my old stuff back? Especially my Login Data and Bookmarks? Why does this not work anymore? Is it due to different Versions? Although I am pretty sure that my old FF was up to date. Is there a Log File?

Also I have an old logins.csv, but it has corrupt/incorrect symbols in it.

We have a proxy server and requested already to whitelist the https://aus5.mozilla.org & http://download.mozilla.org/ but still, we can't manage to update to the latest version. Do we have the complete lists of servers that we can add to our proxy server, to have it whitelisted?

I've been using the portable version of Firefox for years. Every release up to 110 has worked great. But release 111 and 112 won't start.

Dear Sir

I have been using Firefox for a long time certainly all this century, I regret to say that you have done something to the system such that I am unable to get into online banking and on some sites I get a message something to do with a frame whatever that is. I regret to say that i have been forced to make Edge my default browser When you have cured the problem please advise and I will revert to making Firefox my default. Many thanks Graham Blackburn

In trying to startup browser I get this message: The code execution cannot proceed because VCRUNTIME140_1.dll was not found. Reinstalling the program may fix this problem. I tried to uninstall the browser, but it would not let me. Help!

Hi I just wrote you a help request, regarding .. @gmx.net which is closed and not accesible anymore and I want to create a new account on relay. I understand that you send a confirmation code to .. @gmx.net. Is there another way to autheficate me? My new e-mail adress is .. @gmail.com

Thank for your help.
