Tried to reset settings. Does not work. Went to about:config, than tab.mo / print.tab_modal.enabled set to false. Did this method before and it worked. Now this method does not work trying to get print preview back. Firefox is my web browser. I am in windows 8.1. Seems like Firefox did some updates again and now I can not get print preview back! WHY DOES NOT FIREFOX LEAVE WILL ENOUGH ALONE WHEN THEY HAVE SOMETHING GOOD? Bring back the old classic print preview button back and leave it. Now how can I get the old print preview button back???? Need help!! Thanks philm

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.

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?

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

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.

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.

I had to add Javascript because one of my accounts need Javascript to open. After installing Javascript and allowing for all to be 'true', I still get this message when I try to open a 'show blocked content' in my email.

"The address wasn’t understood

Firefox doesn’t know how to open this address, because one of the following protocols (javascript) isn’t associated with any program or is not allowed in this context.

   You might need to install other software to open this address."

I never had any problem before installing Javascript. Thanks for any solutions.

and not only that, when I click on sign in - it shows me a work email address that I rarely use - not my Firefox account / main email. I have to click NEXT then change email address from the drop down menu. I followed the setting attached. but it's still does it. I close Google tab, then go back and im signed out again! It's extremely annoying. How on earth can I fix this?

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

I use Iosevka font as my preferred custom font for websites, I really like this Firefox feature (actually one of the main reasons why I swapped from Chromium browsers), and as of updating my Firefox Nightly to "Nightly 119.0a1 (20230908094535)" version this feature no longer works on all websites, and only seems to work on the search bar when I open a new tab.

Image 1: Settings (unchanged since previous version when this feature worked) Image 2: Search bar in new tab is using Iosevka font correctly Image 3: An example of another website where the font is not being loaded where it did in the previous version.

Thanks.

When watching something on Youtube and I click on the coloured download icon, I get to be able to click on the title of the video. A blue 1 appears in the download icon. When I click again, then click on the blue 1 to watch the download. Nothing happens. The window just sits there and states 'downloading', but it does not happen. This happened last year and you managed to fix it; now Youtube seem to have blocked downloading again. Geoffrey D Dean, Australia.

I went to settings and set firefox to open links in a NEW TAB instead of a new window, but it still opens links in a new window. I did a search on google and when I click on the link for the website to see the information it is still opening in a new window. How can I fix this so I don't have a lot of new windows. It's irritating to have to close all those stinking windows just to get back to my original window. I just want the links I click on to open in a new tab.

Buenos días a todos.

Estaba revisando el historial de navegación de mi Firefox desde el menú Historial/Mostrar todo el historial. Como ya sabéis, para movernos por el historial tenemos de ayuda un menu vertical a la izquierda, en el cual podemos seleccionar un determinado mes. Pero por error he eliminado la carpeta que decía "anterior a 6 meses" y me gustaría recuperarla.

Tengo entendido que Firefox guarda el historial de navegacion en el fichero places.sqlite, el cual ya tengo ubicado, pero no se qué hacer con el.

Agradezco cualquier ayuda. Gracias.

I'm using Firefox 104.0.2 (64 bit) under Windows 11.

Under Settings I have selected Startup Open Previous Windows and Tabs.

I normally have more than a dozen tabs.

For the past few days, when I start Firefox my previous session is not restored and I just get the single Firefox tab.

When I got to History there is no longer a Restore Previous Session option.

How do I get it back?

Thanks

In settings, my default browser setting is greyed out and I have "Your browser is being managed by your organisation". The default browser is locked to Firefox.

I have tried various fixes in these help pages but nothing works to get rid of the default browser lock or the "Your browser is being managed by your organisation."

I delete the key in Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies but it repopulates as soon as I reboot.

For information I have TOR browser as well but there appear to be no issues there. Only problems in Firefox

Can anyone help and unlock my browser default to Firefox?
