Firefox Support Forum

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 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!

/*** Tighten up drop-down/context/popup menu spacing (8 Sep 2021) ***/

menupopup:not(.in-menulist) > menuitem, 
menupopup:not(.in-menulist) > menu {
  padding-block: 2px !important; /* reduce to 3px, 2px, 1px or 0px as needed */ 
  min-height: unset !important; /* v92.0 - for padding below 4px */
}
:root {
  --arrowpanel-menuitem-padding: 4px 8px !important;
}

/*** Proton Tabs Tweaks ***/

/* Adjust tab corner shape, optionally remove space below tabs */

#tabbrowser-tabs {
    --user-tab-rounding: 6px;
}

.tab-background {
    border-radius: var(--user-tab-rounding) var(--user-tab-rounding) 0px 0px !important;
    margin-block: 1px 0 !important;
}
#scrollbutton-up, #scrollbutton-down { /* 6/10/2021 */
    border-top-width: 1px !important;
    border-bottom-width: 0 !important;
}
/* Container color bar visibility */
.tabbrowser-tab[usercontextid] > .tab-stack > .tab-background > .tab-context-line {
    margin: 0px max(calc(var(--user-tab-rounding) - 3px), 0px) !important;
}

Hi, I'd like to disable that annoying animation when going to fullscreen (by hitting F11). Supposedly, setting the following should work:

Go to about:config

Set: full-screen-api.transition-duration.enter 0 0 full-screen-api.transition-duration.leave 0 0 full-screen-api.transition.timeout 0 full-screen-api.warning.delay 0 full-screen-api.warning.timeout 0

Restart

However, this does not have any effect in Firefox 94.0 on Ubuntu. Is this a bug/regression? Or is there some other way to disable the animation?

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?

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

Hi there,

I'm am trying to customize Firefox 91.4.1 ESR for my users who were using 78.10.1 before, however cannot find how to add Library-Button (which was default in previous versions) to their UI. Since I am avoiding to amend pref.js and user.js, and this option is not controlled in latest admx template, maybe there is a way to use firefox.cfg? If yes, then how to add it there? Will it not lock users UI and he wont be able to change it afterwards? How about extensions interfering with UI? Also, will the removal of the icon continue in the next ESR versions?

Many thanks for your help in advance!

I have been a "light theme" user for 15+ years. Since updating to 96.0 today, a dark mode spreading across Firefox has been forced onto me, including:

• New tab background
• Background of any tab waiting to load a page
• Google/Youtube background
• Settings/add-ons/password menu backgrounds
• Automatic username/password drop-down background
• Background of the little box that appears on the bottom-left (the one which shows the URL when you mouse over a link)

I am unhappy with this and wish to have my usual theme back. Can anyone please assist?

(In addition, there is some sort of white border around the current tab, which I do not like)

For over a year (just over a year on this computer and a few more years on a different computer) I have had a custom theme at the top appearing from the file menu through the address bar. The computers have also always had the New Tab menu being a light colored screen. I turn on the computer today, to find I guess Firefox updated last night? and completely got rid of the lightness of that page to make it dark, leaving me on the verge of a migraine every time I have to look at that thing.

How do I get rid of that dark page, back to the lighter version WITHOUT getting rid of my custom banner at the top? (yes I tried to use the light extension in theme and that gets rid of the banner and leaves me with a horrible white at the top which is just as big of an issue for me as all the black. I really need that like muted Tan back.)

My current Theme is Dark Fox. But, previously my backgrounds and menus were all white and easy to read. Now for some reason they're black and difficult for me to deal with.

How do I reset to white and sync them on all my devices?

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

Hey Guys,

My trend micro password manager stopped work recently only on Mozilla but still works on every other browser, I have uninstalled and reinstalled both the trend micro and mozilla but it still isnt working?

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?

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.

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)

I just updated from Firefox 96.0.3 to Firefox 97. When I try to print I get the Firefox preview, even though I have print.tab_modal.enabled set to false. Please fix it so that I can get the print system dialog without going via the Firefox preview. Note that I have now reverted to Firefox 96.0.3 and won't update from this unless the problem is fixed.

Firefox 97 installed itself , and now I have two print dialogs each time I go to print something. I have the system print dialog , and the Firefox print dialog. Does anyone one know a way to turn of the Firefox dialog in 97?

I fixed it in earlier versions by setting

print.tab_modal.enabled = false

...but in Firefox 97 it seems this no longer does the job.

Grateful for any advice.

I have always had the Print UI disabled by setting print.tab_modal.enabled to FALSE. Since the Version 97 update today, this is not working. The FALSE setting is still there under about:config but the Print UI dialogue now keeps coming up.

Prior to FF97 a simply setting to "false" the about:config, print.tab_modal.enabled setting allowed FF to always use the system dialog box when printing. However, in FF97, this is no longer the case. How can I set FF97 to always use the system print dialog box??

I almost always use Preview printing on my Macs to avoid multiple pages of garbage so this is fairly important to me...and it might help to save a few trees...
