After Firefox went haywire every time I tried to upload a file or add an attachment to an email, I eventually found a way to "restore default settings". That fixed ONE problem but immediately caused several new ones: The "File Edit History etc" toolbar has disappeared. How do I get it back? The colours and identifying icons in the drop-down tab menu on the right have also disappeared. How do I get them back? Nowhere to recover them in Settings and no answers to the questions from Mozilla.  :-(

When I enable a theme, it doesn’t apply properly. Instead, the color that appears is just the default color of the browser. Sometimes the theme applies, but when I open a new browser window, the theme I enabled disappears. Why is this happening? Tysm :)

the right click menu used to be matte and used my windows accent color. now its transparent with a frost effect on top, kinda like the right click menu in windows 11. how do i get the old one back

Since update to Firefox version 138.0.1, my last viewed side bar is never automatically displayed upon REOPENING Firefox. I must always > View > Re-select the desired sidebar choice >

How can I get this side bar to re-display automatically upon opening Firefox as it used to in previous versions?

Hello, when many tabs are open, the mute button takes up almost the entire tab. When I go to a tab, I get to the mute button... https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-03-01-03-07-42-491a45.png Is it possible to remove this function on the tab, but leave the sound icon itself? So that when I click on the sound icon, the tab is switched to instead of mute?

I can't change colour of visited links with version 138.0.1 Why has this changed and how can I fix it. If I change the visited links colour, all the website colours are overridden. There used to be a choice.

Opening a new private window (via any method, keyboard shortcut or the button in the burger menu) will show the History sidebar for a very short while, then it disappears. This is very annoying as when I type the cursor is no longer automatically focused in the address bar.

I had to do a system restore to a couple of days ago. When it finished. The text in my tabs and toolbar became tiny, about 8pt instead of the 12pt that it used to be. What setting will make the text larger again like my menu bar?

Hello, so for the past several months now any time i set a custom theme to my firefox browser, it'll work *until* i close the browser and re-open it, the theme goes back to dark theme. its finally starting to get on my nerves, and i thought with an update or two it would fix itself, but nope.

i have tried changing the default from automatic to dark and back again, and nothing helps. i tried looking all over google for any help relating to this issue, but the only thing i can find relating to this issue old archived reddit post where the users seem to have resolved it back then, however none of the suggestions in the thread worked for me (probably because we're now several updates past that one in the thread). please help! its very annoying to have to go in and manually change the theme every singe time i open the browser, if the feature is there it should at the least work properly!

thank you! :)

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.
