Firefox Community Forum

I have Firefox on two computer (plus my phone), both of them are running Linux Mint. On pc#1 Firefox behaves ok; on pc#2 instead it's abnormally zoomed in and it is very annoying to use. I am logged in with my Mozilla account on both devices, they have the same settings and Firefox is the only application displaying this behavior. If it matters, pc#1 has a bigger screen. I've attached a screenshot of the same page visualized on both devices as to show the difference.

(I am posting this from pc#1)

Hi.

I want to ask the setting of theme.

If I don't set the theme, the color of window in private mode is dark (and I know I can change this setting on config.) The other hands, when I set Theme, the color for browser of private mode will be also changed the color of theme and it is same as default one.

I want to recognize which browser I'm using by the color of the window. I can do that if I don't set a theme. Is there any way to apply the theme only default browser or to apply different theme to private mode browser?

I like to have the Sidebar open all the time. Now with version 138, when I re-open Firefox the Sidebar is always closed.

How do I keep the Sidebar open in Firefox 138?

Any ideas?

Thanks.

After Update to 138.0 my sideabar (bookmarks) is away. I can reactivate the sidebar on the left side as wished. But when I open a new Firefos Window or Tab the sidebar ist away again. What have they done, mozilla ?? How can I get mey bookmarks ALWAYS shown on left side of any Window or tab ?

My sidebar kept disappearing when opening a new window. After asking the internet, I learned that this was part of the latest UI update. This is a horrible update (sorry programming team) because if you always want your sidebar to show up, all that extra stuff has to show up as well. See first image.

The second problem is that the Hide Sidebar button is too close to the Back button. I keep clicking on the Hide Sidebar button when I really want the Back button.

Is there a way to hide these controls? I know you can move them to the right, but then, so does your sidebar. I don't have a lot of screen real estate. Can we have an option to go back to the "classic" settings for sidebars?

By the way... In the previous versions of Firefox, I was able to click on a link (example: Google search) and my sidebar (in my case with my bookmarks) was always there in the new window or tab. Now when I click on a link, the sidebar with my bookmarks disappears in the new window. I have to keep enabling it if I want to see my bookmarks. I'm 100% sure that this is causing frustration with over 87% of Firefox users. Can we please bring back that old functionality?

The little button, top right of screen, between - and x is not working to reduce the screen window size. I don't like the window opening to cover the entire screen. I cannot access any edges to reduce the window.

Hello, I've updated my Nvidia graphics driver and encountered this issue. Basically I noticed it on twitch.tv mainly, bottom of my website is hidden behind taskbar, as if firefox thinks I have the automatically hiding taskbar setting enabled, which I never used. I've tried deleting some json file from %appdata% which has not helped, tried reinstalling firefox, running in troubleshoot mode,disabling hardware acceleration and nothing helped. Here are screenshots of how it looks fullscreen and how it should look, as you can see the bottom section is missing. Thanks in advance

When I move the pointer up to a tab, and accidently go to high, this top bar appears on MacOS 15.4.1 - I'm running FireFox 138.0.1 - so I would like to know how to stop this behaviour, and or a plugin or fix to move the close, maximize, minimize button to the left of the tabs, like one Chrome.

Since a couple of days, the sidebar on the left disappears when restarting the browser. I am using 138.0.1. Everytime I have to go to settings to make it appear. Can you help on this bug?

I am now wasting precious time trying to figure out how to make the bookmarks and the tabs across the top bigger. Since the auto update, I can barely read the teeny tiny print. How do I make the font sizes something I can read?

I have applied a dark color combined with some managed custom color. Can anyone help me with how I can disable this overriding website appearance by my color selection for certain sites but enable it for all the rest?

We're attempting to disable either the Firefox Sidebar or the Firefox AI Chatbot via Group Policy, but it appears that Mozilla has not updated their ADMX templates yet to allow this change to be made.

Is this an accurate statement and if so, is there a timeline for when Mozilla plans to implement an update to remediate this issue?

Used to be able to set default background color when not specified by site After last update this feature appears to be gone I found another setting that seems to override site background color and colors. Very ugly, had a hard time deciding reading site information. How do I get what I had back?

I've looked at this page:

https://support.mozilla.org/en-US/kb/customize-firefox-controls-buttons-and-toolbars

It shows the toolbar customization page like in the attached image I've named Customize Toolbar.

In my Firefox (138.0.1 64-bit on Windows 11), it looks like what I'm showing in the attached image I've named My Customize Toolbar.

I like the background shown in the Mozilla documentation. I hate the background I've got. I didn't choose that color. I have no idea where it's coming from. I sure would like to change that disgusting color to white.

How do I do that?
