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?

Outlook recently made Edge or Chrome the default browser, with no possibility (as far as I can see) of choosing Firefox. In Outlook FILE/OPTIONS/ADVANCED, it seem impossible to choose Firefox.

How can I make Firefox the default browser. This situation occurred after recent update (October 2023).

Any help would be appreciated. -- JGS

How do I stop firefox from automatically downloading files from the internet when I click on them - without even asking me if I want to download them in the first place. In "Applications", selecting "Always Ask" in "Choose how firefox handles files etc" does not work. Firefox never asks. If it cannot be disabled, I will have to stop using Firefox.

I have a content filter to filter out inappropriate material. Included in the filter are filters for adult content on wikipedia, youtube,and google podcasts. however, all those sites are fully allowed on Firefox, as opposed to on Safari and google chrome where the filter is working properly

When i updated Firefox just now it offered several recommended security add-ons. I added a few of them. But now I can't access Facebook. I disabled them one at a time and still cannot get in. What do I do now?

Hello, In old versions of Firefox picture-in-picture mode was "always on top" by default, now "always on top" mus to be enabled every time I pop-out every video. Is there any solution to make picture-in-picture mode "always on top" by default?

My default search engine was Norton Safe Search but now it does not appear as one of the options to choose. I cannot remember all of them. Bing and Google are two of them but not Norton Safe Search although I have been able to add it to the toolbar. Why is it no longer one of the options?

For the past few months every restart of Firefox disables LastPass. I did NOT have this problem previously. The version of LastPass is current (no updates found). I can go to Add-ons and the toggle is set to "on" but the icon in the menu bar is black. If I click the toggle off, then back on, LastPass comes on just fine. Why is Firefox disabling something that Add-ons says is loaded? VERY strange. Does NOT happen in Chrome. Thanks for any assistance. PITB!!!

I have Startparge set as my default search engine. I used to type directly into the address bar (see first image).

Press Enter, and the Startpage results page for this search phrase would show up. Somehow, this has now changed. I press Enter, but the result is just the Startpage home page, with a blank search box (see second image). So I then have to type the same phrase in again in Startpage's own box. This just trips me up.

The crazy thing is that this only happens sometimes - but more often than not. I haven't seen it work right for weeks: I just did it now to make screenshots, and it worked wrong. I just did it again and it worked as expected: pressing Enter took me to Startpage's results.

Any clues how to change settings to fix this?

I have a dark themed website with light colored lable that is positioned inside the input field and having the autofill to autocolor the input's background yellow makes things look horrendous. I've tried the following CSS:

``` input:autofill, input:-moz-autofill, input:-webkit-autofill {

   filter: none !important;
   background: rgba(0, 98, 155, 0.35) !important;

} ```

On top of that, I tried changing that for myself in about:config changing ui.-moz-autofill-background to false, but after clearing browser cache and doing a hard-refresh, the yellow autofill background color persists.

That would be a personal fix, but I would rather firefox not murder the theme of my site for others and let me have control of what color the autofill background color should be (if I even want there to be a difference in colors). Am I missing something? I don't simply want to turn that off for myself (although I still want to, but it didn't work). I want to change it for everyone visiting my site. (Like I'm able to change the colors of link or border colors or background colors of other elements).

Hi,

I am a student, who tend to mass download files at once. The annoying part is that after every download, firefox automatically opens up the downloaded file in a new tap. How can I disable automatically open files after download?

Thanks.

Lately, Firefox unchecks the 'use autoscrolling' and 'play DRM-controlled content' options sometimes (but not every time) when it starts. Other settings don't seem to be affected. It does seem to unset both at once, never one or the other at a time.

I have begun using Firefox routinely on two computers, both signed into the same sync profile. My best guess is that maybe one profile is overwriting the other? Both of these options are set on the second system, but maybe there's something going wrong with the sync?

Thanks, Patrick

I'm running Mojave 10.14.6 on a MacMini (late 2018) with 64 GB 2667 MHz DDR4 and Firefox v86.0 64-bit.

I need to disable Command+D that's currently used to "Bookmark This Page".

I need Command+D for another use.

I've searched about:config for "bookmark" and get a lot of hits, but I can't tell which one controls the setting for Command+D.

Or . . . am I barking up the wrong tree?

I want to disable Command+D.

Leaving the ability to mouse up and click Bookmarks > "Bookmark This Page" is ok.

I just need to disable the keyboard shortcut Command+D for "Bookmark This Page".

Anyone got a "howto" for this?

Thanks!

I live with Firefix always in full screen. I Don't like seeing any bars or buttons of any kind.

Befor the latest update, when I moved my mouse to the top of the screen my tabs popped down and in the top right corner was the standard icons for "minimize" "maximize" and "exit".

With the latest update the tabs are there but the 3 buttons have gone.

If I exit full screen (F11) then they are there again, but I dont want to have to exit full screen every time I change between programes which I do every few mins. I'd be popping pages in and out of full screen every few mins!

How do I get the buttons back all the time?

I am in the USA. Every time, on any page or website that I need to provide credit card info, when I click in the box to type in the CC numbers/expiration date/CCV, a window pops up as it should (for auto-fill) with my credit card information. In that window, I can scroll over the different credit cards, click on the one I want to use, and it SHOULD auto-fill into the box where the numbers would normally be typed in. Now, the window still pops up and I can scroll over the credit cards and choose one, but when I click on any of the particular credit cards, the auto-fill doesn't work. The boxes in "settings" are checked to allow auto-fill. It worked for months, then just stopped. Thanks for your assistance!

I'm using Firefox 85.0.2 . . . I was doing this (below), to customize my header and footer, but in this version of FF, I no longer see this in Options - only in: about:config . . . keyword "footer" . . . there, I would have to change it for 5 different ways of printing (to printers or to PDF)

I need to get rid of printing the URL in the footer - many times, it's too long, and I don't need it.

Where did the Page Setup option go?

I see in the current Print Options, you have to go to - More Settings / Margin / Custom - to see those. Why would they put this so many levels down?

It used to be: File / Page Setup / Margins & Header/Footer . . . "Customize" Headers & Footers:

Option 1 (left) . . . there are two leading spaces:

 > > &T
 > > &U . . . &D . . . &PT

Option 2 (left) . . . get rid of the ">"s, and just have the two leading spaces:

 &T
 &U . . . &D . . . &PT
