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?

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.

Where can I get Firefox 52.9.0? There was a list of old versions here but now I can't find it. I found https://download2.portableapps.com/portableapps/FirefoxPortableLegacy52/FirefoxPortableLegacy52_52.9.0_English.paf.exe I really did not want the portable version but avast considers it a threat so it may not be genuine.

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

I need to know how to stop Firefox from automatically downloading .pdf files that I view. Sometimes I just want to view a pdf without downloading the file. Firefox keeps automatically downloading the file, then after viewing it, I have to manually delete. I don't to do this! I just want to view the file and if I want to keep it, I'll save a copy. This is extremely annoying! Can I change the settings so that the file won't automatically save to my computer? and i want show my file or pdf then i want to download the file

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

MY Windows 11 laptop crashed and OS may need to be reinstalled. Will this wipe out my Firefox browser bookmarks. I would like to save the bookmarks somehow. How do I do this without access to that system?

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…

( :( :(

When I try to install Firefox on my Steam Deck (Which came with the installer). It doesn't open. It just says "Cound not open appstream://org.mozilla.firefox because it was not found in any available software repositories.

Please report this issue to the packagers of your distribution." It shows it every time I open the installer ever since I got the thing.

cant find how to add another account, every help thing i find seems to be outdated. i have multiple accounts i use on chrome, and want to move some to here, but i need help finding how

I have downloaded and installed Mozilla Firefox on a new computer through the Edge browser both from the Mozilla site and through the Microsoft store. The installation downloads and installs as it should. Firefox has been selected as the default browser and everything appears as it should. When I open Firefox and type in an address, nothing populates. No site will open on the screen. When I open settings in Firefox, nothing opens. When I open history, it shows that I have been to the sites that I have loaded even though they haven't shown on the browser. I have completely uninstalled Firefox and reinstalled it with the same result. I have downloaded Opera browser and it installs correctly, I have downloaded and installed Firefox from Opera and had the same result. Any ideas?

Thanks, John

I have a new chromebook (Lenova Duet 3) I can install and use Firefox. I have had Dashlane (password keeper) working fine with Firefox for years. The Dashlane extensions work with Chrome, but I can't seem to get them to work with Frefox. The Chrome search engines choices are limited; ones that I never use with Firefox. Is there something in the Chromebook environment that limits firefox capabilities? (Am I looking for something that just is not possible?) Is there a work around? (Any Linux tricks?) I also have asked the same question of Dashlane, but have not heard back yet. My imperfect solution is use Chrome when it is a known website, and the password is recorded with Dashlane, and to use Firefox for new searches, where the choice of search engines is better.

Has anyone developed a search engine where there are no "sponsored" results. I understand that it would probably not be free.

Dear Community,

To be completely honest, I was redirected to this form for this issue after it was posting in the discussion forum too many times about this.

The problem: Firefox has the behavior to download an update and force me to restart my browser

The issue: Next to the fact this is a very obtrusive behavior (or simply...not polite) it is in fact messing up my workflow and mood.

Why important? (at least according to me): First workflow: Using a lot of active connections / 2FA logins in combination with a secure setup where my browser doesn't remember a lot after restarting for security reasons, I need to perform multiple logins again while working with online services. It messes up my worflow, negatively affecting productivity. Also, it generates awkward situations when being in an online meeting, sharing a screen and this happens... unwillingly, unknowingly and just untimely. Updates are irregular and often (which is a great thing it itself!)

And that brings me to the point of mood. Less important -yes- my mood to anyone really I know. It is just a big frustration. I have been using FF since the Netscape days, always advocating for this browser, showing others, helping other to use and see the benefits... And this feels (note it is emotion) like a bad pay back for all those years. Several occassions I just used Safari and it just seems easier. But..I want FF, for its belief, how it was setup and its security and privacy.

I know there are more people that experience this issue.

Please let me know. // Is this issue known to you? // Does it have any priority? Is there a solution being generated? // I have tried things, nothing worked. Willing to try, but please don't come with the right 'settings' ... believe me I have tried. The only options seems to be to completely disable the updating process in the about:config page... but that seems unwise. What do I miss?

Please advice, so I don't get to see the page as in the attachment.

I just installed Firefox on a new Windows 11 desktop computer. I ported my profiles over and it appears everything came over EXCEPT: - Themes aren't working. I've tried switching them and they still don't display. The menu bar is black w/white letters; the toolbar is gray with white icons/letters. - My extension icons are there...sort of. If I hover over them I can see the tool tip but the icon doesn't appear on the toolbar which is light gray in color. I can live without the themes if I have to. Not so much the invisible extension icons. Any suggestions as to how I can get them to appear as they do on my Windows 10 desktop? Screen cap below. Cursor is hovered over the Undo Close Tab extension icon but where's the icon? Any suggestions as to how to troubleshoot this will be appreciated!!

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.

Can I download Firefox and save it to a flash-drive instead of installing it? The computer I need it on has a new install of Windows 7 with IE and it will not browse.

I'm stetting up a testing environment. It's a closed environment with no access to the Internet when it's in use.

The environment is launched from AWS and consists of an Ubuntu 18 desktop and a Ubuntu Server running Apache. The desktop is able to successfully load the website, but with a cert error that the certificate isn't trusted.

When the Ubuntu Desktop launches, it has a fresh install of Firefox, and therefore all the directories in the users home folder are not yet setup for Firefox, including the database where the root CAs are stored.

I'm am able to add the Root CA certificate into the Firefox cert database AFTER the machine fully boots and I run Firefox for the first time. I'm using the 'certutil' package to do this. After I load Firefox, then add the root CA certificate using certutil, I'm able to load the website without error.

I need to add this certificate to the database with the startup shell script for the machine.

Any help is greatly appreciated. Here's the commands I'm using:

1. copy the CA cert into firefox

export ffcerts=`ls /home/testuser/.mozilla/firefox/ | grep default-release` sudo certutil -A -n "testcert" -t "TC,," -i /home/testuser/certificates/testcertCA.pem -d sql:/home/testuser/.mozilla/firefox/$ffcerts

These commands work perfectly after Firefox is run for the first time. I've even tried adding 'Firefox' (with several different switches) into my startup script without success.

Hi there.

This is my first post so bare with me.  :-)

We are deploying the 32-bit version of the Firefox Browser to 4 700 clients and the 64-bit version to only 8 clients; all clients on a 64-bit Windows 10 environment. We will migrate to Windows 11 22H2 this year. The manager for the 8 clients says he wants the 64-bits version just because it's...64-bits. No other reason.

I've read that the 64-bit version can not handle Java, Media Players like VLC and mayby some other plugins. Is that still so?

What is the main reason TODAY for using 64-bit Firefox Browser instead of 32-bit, except for the use of 4 GB+ RAM?
