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.

Hello. The last few days iv noticed that if i have firefox on my second monitor maximized, i have a thick white line at the top now, yet iv never had this before in all the years iv used firefox

Is anyone else getting this?

I do not like the blue background behind My sidebar bookmarks . Is there a way to disable/remove the blue background when using bookmarks sidebar? I am not familiar of how to use syntax editing (I guess its called that), I just need layman terms if possible.

Hello! I am running firefox and had an issue with the URL bar. Before, the URL bar was at the top and right underneath it would appear the open tabs; underneath that were my bookmarks. I don't know what I pressed, but now, the tabs and bookmarks are on top (on the same line), and the URL bar is underneath that -- see screenshot for details. It is a small issue, but it is driving me crazy, since all my mucle memory on where to click etc. is gone. Furthermore, the bookmarks now crowd the open tabs, so if I have a lot of open tabs, I cannot see them all at a glance.

I tried looking for settings, but all settings for customizing the toolbar are about adding items to the URL bar, not switching the position of URL bar and the open tabs. How do I fix this?

hi i was wondering if there is a way to remove this shadow cuz i have the adaptive tab bar extension and i think it will look way more better without this shadow enabled

Fedora 42 x86_64, firefox 145.0

Using FontForge, I created a custom Unicode (NO 8-bit pi encoded) version of the Symbol typeface with a new font-family name.

One of the customizations, the serif versions of the "Registered Sign", "Copyright Sign", and "Trademark Sign" are available by the official Unicode codepoint. The sans-serif versions are available by the official Unicode codepoint *directly* followed by U+200B (Zero Width Space - ZWSP).

This is done with the OpenType contextual alternative feature (calt).

It works in the FontForge metrics test window and it works in Chromium and derivatives but it does not work in FireFox - either the Fedora 42 build or the generic x86_64 build from Mozilla.

I tried the CSS setting:

body { font-feature-settings: "calt" on; }

No dice. I believe that's the right CSS setting because if I change the "on" to "off" then it no longer works in chromium and derivatives, so that does seem to the be the CSS setting that controls whether or not the feature is enabled.

All my searches on the web seem to indicate the FireFox supports calt however all the examples I see are related to swashes which are enabled/disabled by a different CSS setting.

I did see some indication that some apps only allow calt for certain language scripts, typically Arabic and/or Greek and/or Latin and perhaps these legal glyphs aren't considered one of those scripts?

Does anyone know why the calt works elsewhere and not in FireFox? Yes, I tried without any extensions or plugins enabled.

So within the last couple of days Firefox has started toggling the menu bar even though I have it disabled/hidden. If I were to click off of the browser to check Discord for example, it pops up when I click back on and literally moves stuff down--which makes it annoying if I try to click back on to enter a web address.

Anyone else having this problem?

When i right click on something in my browser the menu shows up but none of the options have text. For example i can still open a link in a new tab but there's no text for the option i just have to know witch is witch. This is exclusively an issue with the browser, right clicking on my desktop or on another application produces all the expected menu option with no error.

When I open Firefox, since last upgrade 13-november-2025(version 145.0) it's always in full screen ! I hate this configuration and I want to come back to the previous "normal" starting configuration. Everytime I open Firefox I must do "F11" now. How can I do ?

This concerns the display of bookmarksto the the left of the main display. Fot the record, this is installed om Magea Linux, vers 9, from the OS repository, and is Firefox vers 140.4.0esr ( 64-bit). Up until recently the display was variable in width, and once the box for 'show bookarks' was ticked, the bookmarks display opened in any new ;Firefox' brought up. With the two new features, I have a pair of niggles. One, is that the new sidebar, being fixed width, cannot be reduced. Taking up more screen 'Real Estate', that I consider would be better utilised for the main panel. The other niggle, is that ticking 'Show bookmarks' is not permanent and has to be re-ticked, for any new Firefox' display. I have another machine running the same version of Mageia. I opened this today, and it, while still showing the same version of Firefox, displays the old version. Perhaps, since the Mageia support section have not yet.sent a prompt for update. My query, is. Is it possible for me to return to the old style display, or is there a setting that will do so. The new display, having several options, is possibly an advance. But, for me, bookmarks display is paramount.

Thanks, Rod Goslin

The update to v145 completely changed how background color and highlighting of HTML emails are displayed. It was nicer before. Can someone please share which setting in about:config to change to return to HTML display in previous versions?

Thanks!

recently Firefox has started leaving a small gap at the top of the window with the desktop background (the light blue in the screenshot) is visible when the window is maximized.

This issue doesn't occur with any other program and occurs in troubleshoot mode.
