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?

Hello all. I'd like to restore the backspace button function but the previously workable solution — resetting browser. backspace_action to 0 — is not working for me. Any hints as to why that might be the case?

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.

Today I installed a new extension (Bitwarden) and want to add the icon to the toolbar. I can't find it anywhere. The add-on shows up in the add-on manager but there's nothing there to help me add the icon. The little puzzle piece in the upper right of the browser -- click on that and Bitwarden isn't listed.

How do I fix this? In Chrome there's a simple toggle switch in the extension manager to add the icon to the toolbar. Frankly, if I can't get this Bitwarden icon to display I can't use Firefox at all. Thanks.

Archived 2020 query at https://support.mozilla.org/en-US/questions/1360922#answer-1465978 asked for time-stamped history list. Instructions in the response say after CMD(on Mac)/Shift/H you will see names of columns above the list. This does not appear - possibly deleted since the answer.

I'm trying to argue with a bank that I made a payment in business hours, and a time stamp on my history record would bolster my argument.

Is the list of columns mentioned available somehow? Can a date/time stamp be added to every history record? (Date is known, but not shown as a date stamp.) Is this info in there, but hidden, and available somehow?

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

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?

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).

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?

Hi, how do we set Firefox 97 to use the os/system print dialog?

Before Firefox 97 we could change these settings in about:config:

print.tab_modal.enabled = false widget.use-xdg-desktop-portal = true

But they are both gone now.

There is now widget.use-xdg-desktop-portal.print, which is an integer (2 by default).

But no matter what integer it is set to, we still don't get the os/system print dialog.

We are using Arch Linux, but we don't expect that to be of any importance -- after all, it worked before Firefox 97.

Thanks for your time :o)

You have very practical option for the address bar to separate it for the search bar. See the attached screen shot.

We have many local url addresses to the local web server, which the Firefox does not recognize as URL addresses and redirects to the search engine.

So I said in the option, that for the search purposes a separate bar should be used. But the address bar still redirects to the search engine although I said that that the address bar should be used only for the navigation.

Please make the address bar working for the navigation only if the option "Add search bar in toolbar" is selected. Otherwise there is no sense in the separate search bar.

For years I have been using Firefox. If I clicked on a hyperlink in any of my programs, Outlook messages, websites etc, Firefox opened a new tab. That behaviour has suddenly stopped for websites including this one occasionally. It seems to still work for Outlook. Has Firefox changed its policy?

The advice on https://support.mozilla.org/en-US/questions/1283295 is to edit browser.link.open_newwindow (3) 1:current tab; 2:new window; 3:new tab; But that is already set to 3.

What other settings might work? And why has this been changed?

Hello!

I am multilingual and write in multiple different languages, and the red markings from spellcheck underneath non-English sentences get annoying when they are so frequent. I understand that I can install multiple dictionaries, but that does not allow me to use more than one language's spellcheck at a time.

Is it possible to activate 2+ language dictionaries in Firefox?

Thanks for the help, Sylvan

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 was quite unhappy with the new Firefox Proton design, so I made a CSS file and copied the following code from a website. However, I don't know what to do to (1) slightly reduce the tab height, (2) get back tab borders for inactive tabs and (3) remove the small gaps between tabs. How exactly do I have to change the following code to do so (ideally, for convenience, please just complete the code accordingly)? Thanks in advance for any support!
