Firefox Support Forum

When I open Firefox it's just a black page and anything I click on isn't responsive. I can't go into options or anything. Sometimes Firefox doesn't even load. It worked fine earlier than all of a sudden It stopped working today. Web pages don't load. Nothing works

I seen a post earlier that had a link to a supposed fix but I couldn't figure it out. So if anybody is able to help me it would be much appreciated. I am not an advanced user when it comes to Firefox

After the latest update (117.0 64-bit) I now do not see the '+' sign in the tab bar. I have 40 tabs open (please, no negativity - it's always worked for me), but if I close all of the tabs it reappears. Re-open the original 42 tabs and it's gone again. Close them and it reappears, etc. Now for the fun bit: starting from scratch with a new window - the '+' is there, but open 20 more tabs and it goes.

Unfortunately, I downloaded “SaveFrom.net Helper” without reviewing it.

Since downloading it I have been receiving a alerts from “McAfee WebAdvisor” about “dangerous pages blocked”.

I was able to remove the “SaveFrom.net Helper” add on in Firefox, but am unable to remove the “Savefrom.net Helper” bookmark tab which has high jacked my normal Firefox Bookmarks.

I can no longer easily see my Firefox Bookmarks and have to keep opening the Firefox Application Menu, then select Bookmarks, then select Manage Bookmarks in order to see my bookmarks.

Can you please advise how I can safely remove the “SaveFrom.net Helper” bookmark tab which has high jacked my Firefox Bookmarks.

Hi! Since yesterday, in Outlook, my font size became very tiny for subjects and categories. I can barely see it. Can you please restore them to normal sizes?? I am desperate trying to read them. Thank you! Shirley Savva

Just updated to the latest firefox version 119, and noticed that the url links are now all underlined again. Checked the support page that says it can be undone in settings, but when I opened up to the said setting page, there's no option to uncheck underline links. Where else can underline links be disabled?

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.

Hello, I've followed Firefox's invitation to install and update the browser on my Mac. Unfortunately the new version is not compatible with OS 10 El Capitan, my operating system, so now I can't use Firefox at all. How I do get the old version back?

Thank you, Lars
