I've been using "unload tab" feature in the right click menu a lot, because my device is slow and I like to keep tabs open. (Thank you so much for adding it!) I love that it makes tabs that I unload manually have grey icons, this is super helpful for keeping track of which tabs are processing and which aren't Can you change it or make a setting so that tabs that are not loaded yet (tabs opened by by the "restore tabs when reopening browser" setting for example) are also grey? It would help me keep track of which tabs are loaded and when. In other words, right now it's possible for a tab to have a color icon when it's not loaded, and I want to make that impossible, so I can keep track better.

I somehow accidentally removed the Mozilla Firefox Header that has File, Edit, View, Help, etc.. I can not even check for the version of Firefox that I am running. How do I get it back without losing all of my tabs? I could not locate anything regarding this under the Settings area, where it should be located.

I really enjoy the new sidebar revamp, but I've had an issue with it recently that I haven't been able to find a solution for. Typically, the settings gear is supposed to be situated near the bottom of bar. However, as demonstrated in the attached image, it is at the top near the bookmarks and history buttons. I have tried reinstalling the browser from scratch, turning the sidebar on and off, turning vertical tabs on and off, and even getting rid of my custom CSS theme for a time. None of these have worked. If anyone knows what the root of this issue is, I'd really appreciate the help.

Hello, I am having and issue where my bookmarks toolbar keeps disappearing. I have the settings to have it "always show", but it is not there. I have to right click on the toolbar and select one of the other options then go back and select always show and then it reappears. What can I do to fix this? Thanks!

Hi,

I've recently removed Sidebery as a extension, as Firefox now offers a similar feature - I'm really happy for that. I'm using the sidebar with "Expand sidebar on hover" on three different computers, and notices it many times every day, that the sidebar doesn't expand when i hover my cursor over it. In that case, i usually press the sidebar button so it's expanded by default, waits a while and try again.

Sometimes i notice that it doesn't trigger when the firefox download section or history "pop-up" are open - it would be nice if it did, sometimes i need to move a downloaded file into a webpage on another tab, but can't remember what favicon - but that's not really the cause of this question.

Is there any way for me to debug the problem when it's bugging out? Or is it something known? I can't find any else complaining about it, but as said, it's on all three of my computers (Win11), which all of them have two different instances of Firefox (Normal Firefox and Dev Edition) which are all synced between computers, so all 6 browsers are "doing it", and i can't seem to find a pattern or a cause.

Yesterday I switched on my PC, opened Firefox and the home page was black. See the attached screenshot. This is not caused by some accidental switching on of the dark mode. Dark mode is clearly off. Neither can I adjust settings to make the Google home page revert to its customary light grey shade.

This isn't a big deal, I know. And it has happened before and in a short period gone away by itself. Maybe it is to do with a glitch in the latest Firefox version. But it has an unpleasant appearance and discourages surfing.

My Chrome Google home page doesn't have this issue.

Can anyone advise on how to fix this unwanted black screen problem ?

how to remove this line from vertical tabs bar? vertical tabs bar has another line above all tabs, below pinned ones, but it's not colored so it doesn't bother me, but this one is colored so i want to disable it

I just updated Firefox to 144.0 On the home page the Firefox logo came back. I went into about:config to check if the update changed the browser.newtabpage.activity-stream.logowordmark.alwaysVisible setting from false to true. It was still set to false so it seems setting it to False is no longer working. Has anyone else noticed this? or Does anyone know any other way to remove firefox logo?

MacOS 26.0.1 Tahoe Firefox 143.0.4 (aarch64)

There is a white border around the webpage content in the browser (screenshot attached). This border exists even in troubleshooting mode, with all extensions disabled, regardless of toolbars or theme, etc. The only place it does not appear is the about: pages (screenshot attached). I've uninstalled and reinstalled Firefox and updated MacOS. The issue disappears when I quit and reopen Firefox but reappears when I resize the window. Is there some obvious checkbox setting I'm missing? I cannot figure out what is causing this. Thanks for any help.

Hello. I'm having a sudden problem. Both the regular search screen and the image search screen are misaligned, overlapping the search box, or showing through. I have no idea what's causing this and don't know what to do. Restarting the computer doesn't work, and disabling add-ons doesn't work either. The cause is unknown. Windows 11 Home Windows version is 23h2 Firefox version is 144.0 64-bit.

I'm trying to set different themes for normal and private browser windows (to easier tell them apart, same as with default theme) but can't find the way to do that. 😢

After the update on the 14th, dark mode has gained weird stylistic choices that I cannot find a way to alter: namely, when closing a new tab, a white box with black font appears -as opposed to the previous darker toned grey/purple with white font. However as of writing this post, I notice that dark mode is not working on this webpage. Seeing as I have an extension enabled in addition to the basic dark mode selection in Firefox settings, I can only imagine that something was broken in the update. Please advise, the change is jarring.

For example, this code in userChrome.css will work for showing a custom favicon on the bookmarks toolbar:

.bookmark-item[label="Bookmark"] image {

   width:0!important;
   height:0!important;
   padding: 0 0 16px 16px !important;
   background:url(custom-icon.png)!important; 
   background-size: 16px !important;

}

However, after a recent update, if the bookmark is located inside a folder, the custom favicon will not be displayed and it will revert to the websites favicon.

See the attached image example of a bookmark on the toolbar vs. inside a folder.

So my question is Firefox is on my Cent OS 10 machine and it only shows the close button on the upper right corner, I would like to know two things, 1. How to add the Minimize, Fullscreen buttons to just the close button on the upper right corner. 2. How to get my menu bar back - the home button and all of the other goodies that normally show on the left of the browser just above the Forward, back and refresh buttons?

Thanks in advance for the help.

So, whenever you open/close the application menu, it fades in/out respectively. It's super disgusting I don't even know why it's not disabled when I have animation effects turned off on Windows. like bruh

This actually happens on multiple UI thingies, I just realized. -_- So if there's a way to disable all these terrible things I'm open to it. (ignore the reply i made, i didn't realize i can edit my question 😹)

DAM SERVER ERROR! Every thing I wrote here is now GONE! Is it possible to make sidebar & drop down list LETTERS LARGER? The're tiny, too small to see without he magnifyer. Shrinking the page has no effect on the sidebar or the drop downs which stay tiny I cannot see tiny letters, I have to use the magnifier to see them & that is very awkward.
