tl:dr Here's the CSS to put in userChrome.css file. This is the "hides everything" option. See toward the end of this post for others.

  1. navigator-toolbox:has(#PersonalToolbar[collapsed="true"]) {
 visibility: collapse;

}


+++

I was looking for a way to hide the nav bar and ran across this older forum topic (https://support.mozilla.org/en-US/questions/1288181).

The solution shown here seems to be non-functional these days (early 2024), but it gets us in the right direction, so below is the code for us to look at.

  1. main-window[chromehidden*="toolbar"] #nav-bar {
 visibility: collapse;

}

This is CSS, meant to be copied into a text document, itself placed in a folder called "chrome" that you'll need to create in your browser's active profile folder. Per step 6 in the instructions (https://www.userchrome.org/how-create-userchrome-css.html) linked by @jscher2000 in the above-linked forum topic, you'll also need to set toolkit.legacyUserProfileCustomizations.stylesheets to "true" in about:config. If you don't know what about:config is, this is a good example to get started, but I'm not going to explain it here.

This CSS code selects the object with ID #main-window, with an HTML attribute "chromehidden" equal to "toolbar", and sets its CSS property "visibility" to "collapse". Apparently Mozila have changed the way they implement toolbar hiding, as this no longer works — this chromehidden attribute is nowhere to be found in the HTML that drives the Firefox interface, not sure if that's the place to look for it, but I think so. Anyway, we need to dig around in this interface HTML ourselves to see what changes when hiding the bookmarks toolbar, so we can adapt a new method to what's going on in the browser now.

To do so, we open a window within a window (chrome://browser/content/browser.xhtml) and run the inspector via Web Developer Tools. Comparing the HTML we see here with the bookmarks toolbar in each state (I used BBEdit to compare the texts), we see that the object with ID #PersonalToolbar experiences a change in its "collapsed" attribute when we hide/show the bookmarks toolbar. So in our CSS code, we shift our strategy to update the "collapse" CSS property for #navigator-toolbox whenever it contains a #PersonalToolbar object with its own "collapsed" attribute set to "true", which occurs whenever we hide the bookmarks toolbar. Somewhat surprisingly, this approach of updating the CSS property seems to auto-reset on its own when the "collapsed" attribute is set back to "false", which occurs when we show the bookmarks toolbar again. In other words, it simply toggles with the visibility setting of the bookmarks toolbar, and we don't have to write any further code.

If you're interested in hiding some other UI element when hiding the bookmarks toolbar, you can modify this code to do stuff like that (but to go beyond the below examples you'll need to suss out the object IDs, CSS properties, and HTML attributes — and maybe more, depending on what you're trying to do — on your own).

But for convenience, here's an example that hides just the tabs:

  1. navigator-toolbox:has(#PersonalToolbar[collapsed="true"]) #titlebar {
 visibility: collapse;

}


Here's one that hides just the URL bar:

  1. navigator-toolbox:has(#PersonalToolbar[collapsed="true"]) #nav-bar {
 visibility: collapse;

}


Since those are the only other two things in the #navigator-toolbox to be hidden, I suppose that means we now have all options on the table (at least the way I have the browser set up). Enjoy!

I'm an instructor that uses Blackboard at college. When I click in the text entry box to enter my grades, I'm given a list of previously entered grades to choose from. The list is in ascending order. Is there any way to get this list in descending order? One other point, until recently it used to display the value that was used most often at the top, which was often 100. Now it's in ascending order. I've attached a snippet of what I mean.

I was browsing a webpage that turned out to be in Portuguese, and I was looking for how to translate it, but the internet indicated that Firefox has built in transation! However, neither the Translate Toolbar Icon nor the Translate menu option appear, even if I visit a site that absolutely should be translatable (https://fr.wikipedia.org/wiki/Mozilla_Firefox)

Additionally, if I go to Settings -> General, there is a Translations section, but if I click the Settings button, there are no languages in any of the boxes and no option to add any.

I am on Firefox 126.0 for Windows.

Here are the things I have tried:

  • Restarting Firefox
  • Rebooting my PC
  • Disabling all my extensions
  • Running Firefox in Troubleshooting Mode
  • Clearing my Startup Cache
  • Performing a "Refresh Firefox"
  • Toggling and Untoggling browser.translations.enable and browser.translations.automaticallyPopup

Does anyone have any suggestions of something I could have missed?

Running Firefox 126.0, which Firefox' About link says is current. Dell laptop running (current) Win10 Pro.

As recently as last Wednesday (15 May 24), everything was normal. Since yesterday (16 May), on the Wall Street Journal site, after I have logged in, I no longer have access to articles' comment threads. The Show Conversation button shows 0 comments (which is erroneous), and when I click the button, it changes to Hide Conversation (which is normal), but nothing else happens--just white space and no comments or comment text entry field.

On Fox News, the comment thread doesn't display, and there's not even displayed a link to a comment thread. Until yesterday, the thread normally displayed, but required login to comment. Since yesterday, logging in changes nothing: the comment thread still doesn't display at all.

On X (nee Twitter), when I click the login icon, I get the usual login box--but it's solid black with only a rotating arrow signifying "loading." It never finishes loading. An added fillip: X, as recently as last Wednesday, displayed in its usual black text on a white background. Now it displays as white text on a black background. I can click on X links sent to me and get that particular X post to display, but I cannot log in.

When I go to those sites in Edge, everything behaves normally: I have access to comment threads, and I can log in to X. One exception: X displays as white text on a black background on Edge, also. This doesn't seem to be an X thing, though; on my wife's laptop (Firefox 126.0), running WIn11Pro, her X display is the "normal" black text on white background.

I haven't changed any settings in Firefox. I do have a couple of ad blockers, and I've turned those off, one at a time and both together; that had no effect.

How can I get things back to normal in Firefox?

Thanks

I've been using custom icons for all of my 36 shotcuts on Firefox start page. Today I opened Firefox and my icons are gone, Firefox slowy created its own ones and now I can't refresh them to bring back my own, despite there are my links pasted into entry. This is how it looked like: https://i.imgur.com/4C9jaqK.jpeg and now it's like that: https://i.imgur.com/VDIoggt.jpeg absolutely horrible and it's not the first time Firefox did that. It's really time consuming to bring back old icons one by one, I have to upload each of them again to get new links, because somehow Firefox sees old links being in use and there's no way to refresh preview of them. Please give me faster method to bring back my old setting, I really hate changes so much!

Unattended software (kiosk) here.

Sometimes (so rarely that I cannot reproduce in dev) the client sees this error screen: "Firefox closed unexpectedly while starting..." (see image in attachment)

Sometimes when rebooting the error goes away and Firefox starts normally.

Sometimes even when rebooting the system - this vertical error screen appears, and one solution is to reinstall Firefox, but I'd like not to (if not necessary) or at least programmatically detect the issue and perform the needed actions.

QUESTIONS: How to programmatically detect (bash i.e.) that this error window is present and get rid of it properly? Or, how to (for debugging) force that screen to appear (to force that broken state)?

PS: I'm running Firefox using:

nohup firefox -P ff_custom_profile -new-instance -private-window -kiosk "$url" > /dev/null 2>&1 &
