Diễn đàn hỗ trợ Firefox

My computer updated with no warning one night, and i lost all personalization and even everything stored in my firefox, the sign ins, passwords, bookmarks, all. is there a way for me to find all that was erased?

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!!

For a week or better I have been unable to download anything through my Firefox browser, I have refreshed and uninstalled Firefox (I had to reinstall through another browser) in an attempt to fix this issue to no avail. I cannot download from verified sites, nor am I able to download Firefox's own extensions or themes (when I attempt I get an error telling me to check my connection, screenshot included).

I would like to be able to use Firefox normally again, with the ability to download files and install my extensions restored.

I wish to export, and not copy, a digital certificate so that I can import it to Keychain on my Mac. The only option in Firefox Browser on Mac is to copy, which means it only opens as a TextEdit and cannot be imported.

Any recommendations?

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.

Recently I have found that I cannot download statements from my bank account, also at the same time (2/3 months ago) I cannot access a Tesco website from Firefox. I can carry out these functions easily from Microsoft Edge, so why the sudden change ? Can anyone please help me to fix this in Firefox?

I have been getting the "new version available, download now nag for over 2 weeks, and I have the latest version. Still get this issue repeatedly every day. Starting to become an every hour nag to update and install latest version of Firefox. Refuse to use Microsoft Edge or Chrome, and will switch off Firefox too if not rectified.

I reset a computer, deleting all my files. I want to use, as I do elsewhere, Firefox as my browser. And though I signed into Firefox using my old credentials, none of my bookmarks are there. How do I complete this setup?

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

I will be receiving a new HP Laptop to replace a 2013 Dell Inspiron desktop and would like to to transfer my Firefox browser, settings and bookmarks when it arrives in a couple of weeks. Can you help with the easiest way for me, who has some knowledge but not the greatest at Tech. ? Thank you !

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.

I've become VERY diligent about replacing my old, simple passwords.

I no longer repeat passwords, have long complex logins, everything (not to mention 2-factor notification on sites that have it)

I was shocked that after I updated to 124.0.1 that alot of my old passwords showed back up in my saved logins

Fortunately that doesn't mean that those are still active passwords on there respective sites.

However, how do I get my "saved logins" back to it's form BEFORE I updated to 124.0.1.....it seems that the update is what did it

the only solution I can come up with is just manually delete all the old ones that showed back up...I really don't want to do that

For what it's worth- I do have a "Old Firefox Data" file on my desktop

I'm currently running MacOS Sonoma 14.2.1

Thank you I hope you can help

Firefox cannot access my bank account. Bank says hello to my name when I log in, but then keeps saying "loading" and can never show me what is in my bank accounts. Why?

Dear Mozilla:

It is SAD that the OS I have will no longer be supported due to exploits.

Considering the # of exploits, backdoors, poor coding, etc., in the later Windows OS versions - 1 would truly think that supporting the older and MUCH more secure Windows OS's would be wise.

Yes, they have "holes", but overall much fewer than current OS's.

Plus, the bad actors are very busy exploiting 10 & 11 and pretty much have ignored the prior versions.

Question... what if a major exploit is found that affects all OS's from 11 down to unsupported?

Will Mozilla make sure to supply a patch to the unsupported due to the danger of the new & serious "hole" found?

I vote... it would be wise to maintain a small contingency of legacy developers to help those who cannot buy new systems or flat out HATE the UI & UX of the 10 & 11.

Makes sense?

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.

After wipe of drive and reinstallation of Ventura by the Apple Store, and migration from Time Machine, Firefox won't launch. It's there, but it won't open. Click the icon and the icon moves as if it were going to launch, but the app doesn't open. If I were to reinstall Firefox, would it sync with my settings and Bookmarks?

I am running Edition Windows 11 Home Version 23H2 Installed on ‎10/‎13/‎2022 OS build 22631.3447 Experience Windows Feature Experience Pack 1000.22688.1000.0 Device specifications; Device name MSI Processor 12th Gen Intel(R) Core(TM) i7-1280P 2.00 GHz Installed RAM 16.0 GB (15.7 GB usable) System type 64-bit operating system, x64-based processor

When I click on install Firefox 124.0.2 the following window pops up stating; Sorry, Firefox can't be installed. This version of Firefox requires Microsoft Windows 10 or newer. Please click the OK button for additional information.

Which opens up a new window giving me the following installation requirements.

Firefox System Requirements Firefox 124.0.2 Windows Operating Systems (32-bit and 64-bit)

   Windows 10 or later

Recommended Hardware

   1 gigahertz (GHz) or faster compatible processor or System on a Chip (SoC)
   1GB of RAM / 2GB of RAM for the 64-bit version

As previously noted, my windows operating system and hardware meet the Firefox System Requirements.

Please let me know what needs to be done to install Firefox 124.0.2

Thank you! John

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
