New computer (Windows 11) shows 'Old Firefox Data'. Opened hidden files. Using File Explorer found Profile Folder & renamed it 'old'. Copied and pasted 'Old Firefox Data' as new profile. Firefox would not open. Had to remove etc and Firefox worked again. Thought this maybe the easiest way to get my Bookmarks back.

PS Presume Profile Folder does not contain Thunderbird Addresses?

I was trying to update firefox but kept getting an error of download failed. I uninstalled firefox, but I now cannot even download the setup file, using either Google Chrome or Microsoft Edge. All I get is is an error saying "site cannot provide a secure connection" (see attached image). How can I re-install Firefox?

Dear Community,

I am trying to download a large file. Am on a course, and the main tutor has given the group a file to download. Have tried downloading this 5 times, but get little luck. The file that I would want to download is 8.5GB, and the furthest I get is about 4GB.

I have 2 questions about this.

1) I seem to have a very 'in and out internet connection. It seems to go down at times for no reason, cutting off the download. Is there anything I could do about this? How could I troubleshoot this, please? 2) Does anybody know of any special tools that I can use to download in a more efficient manner, please? Perhaps an extension for Firefox might be able to do this, perhaps? Kind Regards to Anyone Answering this Query, Marek

I've been doing this sort of exercise for some time, but I want to verify exactly which files and folders I can confidently transfer from one profile to a new or an already established profile without causing unexpected issues.

According to Recovering important data from an old profile , these are the files that can be moved:

places.sqlite favicons.sqlite key4.db logins.json permissions.sqlite search.json.mozlz4 persdict.dat formhistory.sqlite cookies.sqlite cert9.db handlers.json

I also include:

The "sessionstore-backups" folder sessionCheckpoints.json sessionstore.jsonlz4

Here's the list I need feedback for:

The "settings" FOLDER

activity-stream.discovery_stream.json activity-stream.topstories.json AlternateServices.txt autofill-profiles.json blocklist.xml broadcast-listeners.json cert9.db compatibility.ini containers.json content-prefs.sqlite notificationstore.json pkcs11.txt protections.sqlite SecurityPreloadState.txt serviceworker.txt signedInUser.json SiteSecurityServiceState.txt targeting.snapshot.json Telemetry.FailedProfileLocks.txt Telemetry.ShutdownTime.txt times.json webappsstore.sqlite xulstore.json

Please also let me know if any other folders are ok to relocate as well.

Over the years I have accumulated important links in my Firefox Bookmarks bar and passwords file and it would be a disaster if for some reason my hard drive got compromised and I could no longer access them. Is there any way to copy the data to another set-up, independent of my laptop, from where the data could be retrieved in a usable form for display on another laptop or PC? Thanks.

I'm having a problem with Win 11 that will likely require that I reinstall the OS. I decided to move most of the data in my User folder by right clicking and changing the drive from "C:" to "E:" in the Locations tab. Firefox was closed as a I did this, it worked fine, and then I restarted the PC. Upon opening Firefox none of the extensions are working and I'm not sure what to do.

Why is this so difficult? I keep getting the attachment. How do I stop it? I NEVER WANT FIREFOX TO TELL ME THERE IS AN UPDATE. I will check and update when I'm ready. How do I stop this?

Every time I allow Mozilla to update Firefox, smooth scrolling ceases to work. Think maybe I've now had enough. Chrome can't be any worse than this.

Hi there!

I'm attempting to migrate my Firefox (106.0.3) profile from the Linux Mint V20.3 on one SSD to a new installation of Linux Mint V21 on a separate SSD. I'm using the information supplied on this page:

https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles

Step 4, under Backing up your profile says: Right-click on your profile folder (e.g. xxxxxxxx.default), and select Copy.

This folder, qspfoqtl.default, contains 1 file, named times.json, the contents of which are:

{ "created": 1618792039414, "firstUse": null }

Clearly, not my Firefox profile.

There is, however, a folder named nnob5aww.default-release that contains a bunch of directories and files (505.4MB) with names like bookmarkbackups, browser-extension-data... storage, weave.

Is this documentation incorrect as of this release of Firefox? And, should I be using the nnob5aww.default-release folder as the profile? I'm a little confused. (Most often, I'm a lot confused.) Any help would be appreciated.

Thanks in advance,

- Ralph

We have 2 desktop computers, both on the same wifi internet wireless network. On 1 we can ad the Ublock Origin extension no problem. But except for only 2 times, the other computer says installation aborted because add-on appears to be corrupt. Like I said, we have gotten it to load twice but both times it disappeared and now it won’t load. I’m not sure how it can be a connectivity issue, since they both access the internet from the same source. Is it that the problem system has Window 11 and the other 10? Why would it install twice and then disappear? Note that as a test I have uninstalled Ublock and then reinstalled it no problem on the Windows 10 machine. Does anyone know how to fix this? Thanks.

Greetings everyone,

Firefox is my preferred browser and I really prefer the Firefox Engine over Chromium that most other browsers use.

I want to install a backup browser that runs the Firefox Engine in case my Firefox browser has a problem.

I searched a lot and I thought installing this would be the best option: https://www.mozilla.org/en-US/firefox/developer/

However, I’m worried that installing the Firefox developer edition will change my Firefox installation…

( :( :(

I wish to install and use the Firefox browser on my old 64bit Windows 7 laptop.

I believe the last v115 will be the last Windows 7 compatible version of Firefox, if this is correct where can I find this or the correct version of Firefox to download and install on my Windows 7 laptop?

The Firefox website only seems to provide v119 now.

Thanks, Graham

I am currently having problems with my Firefox browser. For example often if I type something into the google search box at the right of the address bar and hit return nothing happens until I go down and select Bing instead of the google setting. Also in hotmail (I am on a desktop) if I go to reply, the original is now ether twice. This does not happen if I use Google browser. But I prefer Firefox as I have used it for years.

My concern is if I delete Firefox and reinstall it, I may lose some of the settings or bookmarks that I have set over the years.

Any suggestions? Please simple as i am old and not computer savvy.

Your help would be so appreciated. I am currently on Firefox 107.0 (64 bit)

Thanks, Anthony

As the title says i have enabled always ask where to save files but when i try to download files it saves them in my Download files most of the times.I didnt have the problem yesterday. Can you please help.

Firstly, I have looked around on here for a bit and have not found anything.

I uninstalled Firefox because it was needing to update for a very long time, giving me a pop up every time I would open the browser, but if I clicked on the update button, it would just take me to a page on Mozzila that showed nothing regarding updates - if you scrolled down you'd get a normal download button for the entire browser which I already had. On settings, it would tell me my browser is up to date. Websites would give me pop ups saying I need to update my browser.

So I uninstalled it. And now I can't reinstall it.

I have Windows 10. On the Microsoft store, I have Firefox, but the "install" button does nothing. This is typical for the Microsoft store for me. On the Mozilla website, I can't get past the initial download page, I click download and it takes me to an error that says "this site cannot be reached" (so, please, do not link me to https://www.mozilla.org/en-US/firefox/all/#product-desktop-release or https://www.mozilla.org/en-US/firefox/new/ both take me to the same error page). I have already turned off Windows Defender, and turned off my ad block.

All of the info I have found assumes I already have the installation files, but I cannot access those because of getting the error I described above. No idea where to go from here.

52.9.0esr is claimed to be the last version for XP. Unfortunately it is not quite true. It is for XP SP2 ONLY. Trying to install on SP3 ends with the message that SP2 is required. IMO the installer is simply too strict on demanding exact version of SP ! https://www.mozilla.org/en-US/firefox/52.9.0/system-requirements/

I went through the list of versions (thanks Mozilla that they all are still available!) and found that the last version I can install is... version... 12.0b6. https://www.mozilla.org/en-US/firefox/12.0/system-requirements/

And indeed I installed 12.0b6 successfully but I would like to install 52.9.

Since support is being discontinued for W7 Firefox, would someone please recommend the best version of Firefox for Windows 7? Security is not a concern, since I have reliable 3rd-Party security setup(s) for my Windows 7 systems.

Thanks!

I have trouble downloading the newest version because it says that Firefox has ended support for Windows 8 and Vista.

But I DO NOT USE THESE OLD VERSIONS - I DO USE WINDOWS 10 on this computer.

Could you please let me know how to fix this in plain english so I can easily do it myself - I am no computer wizzard.

Your help would be greatly appreciated. Please write your answer to my email account: [removed email from public] ,

Thank you, Chris

I have been using Firefox for ages and never had a problem - love it - but now I see the remark: Firefox has ended support for Windows 8 and Vista on my screen at the right top corner. It also will no longer update my computer.

I do have and use Windows 10 - so I don't see what is the problem? I tried to refresh and that didn't work either.

Please help because I like to stay with Firefox but I do need to update and keep my computer secure.

I am not very computer savy so please tell me what to do in simple word.

Thank you for your help Christine
