Firefox Community Forum

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!!

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.

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.

For some reason, Firefox just stopped working yesterday. The only way I could get it to work again was to uninstall and reinstall (the refresh option did not work). However, now I've lost all my bookmarks, passwords and customization. I don't care about the customization and losing the bookmarks is an annoyance, but I'd REALLY like to get my passwords back. The installation created a folder of Old Firefox data, but when I open the folders that I think might be helpful, like bookmarkbackups, they are empty. Is there anywhere else I can look where these might have been saved? I did not have a Mozilla account so no profile until now which I just set up in order to access the forum. Thanks for any help you can provide.

Hello!

I'm writing because I cant seem to import my old profile using this [tutorial]. I have followed it thoroughly, and every time I open firefox its still the same default page that you get when u first download the browser.

A few weeks ago I saw an Mozilla ad for a new Mozilla software product that cleaned up your PC and made it run better. The price was around $125.00 (I don't remember that exact price). It said that I would receive an email from Mozilla with download instructions. it's been a few weeks and I have not gotten any email. Does anyone know if Mozilla offers any such software or did I get scammed? I'm pretty good about seeing scams but Ive used Firefox and Mozilla for years and trust them. Maybe that's why I wasn't as careful as I should have been.

Thanks for any help that you can provide. Ron

Not sure if this is a new 'feature' post-update but it's damn annoying. I was busily transferring some photos that I'd taken on my phone over to Firefox on my Mac. Wasn't until I went to find them on the Mac where they would normally be and couldn't find them. Bit of digging, opening up the Download 'history' on Firefox and saw "File not downloaded: possible security risk".

I can see that I can disable this 'feature' but it seems to be a global "allow". Is there any way I can tell Firefox to allow any downloads from my devices on my network yet warn for potentially insecure downloads from the web?

TIA

For the past week, my browser does not auto-update. I have to download the update and re-download the browser.

I went into the settings and found the update section and when I clicked "Check for Updates", it kept saying "failed to check for updates". I tried with my proxy-settings on with VPN on, proxy-settings on with VPN off, proxy-settings off with VPN on, proxy-settings on, with VPN off.

This is in my personal laptop, where I am the only and admin profile.

My Firefox used to to auto-update but now it keeps saying I need to download the update, but my browser can't even tell if I have the most current version or not.

Hello,

When I go to update Firefox through the settings > general > firefox updates > check for updates, I am getting the error in the title. I can manually download the app installer and update to the most current version which is what I did for version 125.0.1, yesterday.

I have tried uninstalling and reinstalling firefox, installing the beta branch, refreshing firefox, running in troubleshooting mode, completely deleting all user firefox files, and I still get the error. No DNS resolver issues to the update server. No firewall issues. No network blocking (tested with other devices).

This issue started after March update to 124.0.1 and continues to current stable release 125.0.1.

This issue also seems to extend to checking for extension updates.

Below are browser logs for when i try to check for update or update extensions.

I have migrated from old MacPro to new Mac Studio. Firefox ESR version 115.9 has migrated with it. I've downloaded the latest Firefox but it operates independently of the ESR version. How do I ensure new version has all log in, contacts and history?

After updating a W10 laptop from 115 to 116 of FF the user started having problems with getting to different websites (sites they worked on/with regularly). The problem is the cert DB. The doc I found says that it is cert8.db. Actually it is now cert9.DB.

What I had to do was go to task manager and kill a task that was holding the cert9.db file. Then I could rename it (cert9.old.db). Then restarted their laptop and FF came up and started fixing the cert file (as expected). This seems to have fixed their problem.

I am running version 125.0.3 (64-bit) on Windows 11, and I can't check for updates and have to manually download each new version after given a popup telling me that the latest Firefox update couldn't be installed. I've tried restarting the computer, tried running the Mozilla Maintenance Service, and installing the latest updates for Firefox and Windows 11. Nothing I've tried has worked, and no other help article has helped me thus far.

I keep getting notifications asking me to update firefox every couple of days. I download the update, it goes smoothly, the notification disappears, but it comes back in a day or two. I also have my setting to supposedly do updates automatically, but that doesn't seem to be working. Please help!

Ive tried reinstalling firefox because i am not able to download anything with this browser. I thought freshly installing firefox would fix the issue and allow me to download but it didnt. I also am tried to download an addon/extension, and that automatically fails to download. How can i fix this?

Prior to getting some desktop PC upgrades that required a new install of Windows 11 and a new install of Firefox, I backed up my entire PC (yea!).

Now that I have re-installed Firefox, I see that I have none of my saved bookmarks and so I want to restore the Firefox profile - all of it or at least the bookmarks.

I have tried following the Firefox instructions for this, but am apparently not doing it right.

I can't seem to locate the bookmarks file, for starters, in my backed up files. I find the profile but I don't find anything like places.sqlite.

Can someone help me so that I am locating the right (and complete) files, copying them correctly, and then switching to the new/old profile correctly?

Thanks in advance.

Hello Ladies and Gentlemen!

Please read my post completely before answering! Thank you!

I'm using

• Firefox DevEd (manually installed) as my primary driver and
• the standard Firefox (installed from the package manager) for leisure/hobby related browsing

each with its own Mozilla account and profile, on Manjaro KDE. Sadly, either Firefox sees all the profiles. They have usually different versions. If I mistakenly start one of the Foxes in the other Fox's profile, the newer version of Firefox (usually Firefox DevEd) autostarts migrating that profile. Which it renders the profile "corrupted" for its intended Firefox.

I'd like to have Firefox DevEd unable to see profiles (or anything else) intended for the standard Firefox and vice versa. Or at least unable to botch profiles. I do not want to disable migration or use no. Given that Firefox configuration location is hard-coded, I'm not having high hopes for my wish.

I'm wondering if there is a way to keep two Firefox installations completely isolated, other than running them in containers.

Thank you for your time!

Dear all,

We develop a system on D365 platform. On Chrome enviroment, I click the export option, it will download the excel file, I can open it on Excel. However, I click the export option on FireFox, it will download the excel file but I can't open it on Excel.

I don't know why the file content will be change HTML content when I use the Firefox to download it.

Please help....
