Firefox Community Forum

I mistakenly agreed to update Firefox to V 151.02. Once again I regret it but there is no way to turn off the stupid prompt windows telling to you to update.

Now when i open a new tab , the wasted space on my COMPUTER screen is incredible. Instead of the old format withm3 wide "columns" of suggested stories/articles it is now one prominent, and a narrow list of only two wide. requiring me to scroll down twice as far as I used to. I have large white blank unused screen space being wasted. It seems to be optimized for only people who use their narrow phone screens only in portrait mode.

I hate the random useless changes that affect my normal everyday usage of the browser, without any options to go back to old formats or settings.

I am actually thinking of switching to EDGE, or Chrome on my Windows computers.

Wish Mitchel was still my student as I would vocalize my complaint directly to them. But that was back in the days when it was a responsive community .org. Not the now privatized for profit entity that Mozilla has become.

As i had to create another useless account just to submit any sort of feedback, watch as I get constant useless emails with no relevance to anything in my life, as all i wanted was a simple way to make my screen the same as it was for the past versions

Whenever I open Firefox in my laptop, many pop up news snippets start appearing. It disturbs me and intrudes into my work. Please stop all pop ups and notifications. Thank you.

So, I recently updated my copy of Mozilla Firefox, and I noticed something strange. The button for the built-in VPN is disproportionately large to other buttons and clickable elements. I don't see it in the release notes, so I doubt this is an intentional design choice by the UX team, at least I hope it isn't. Any help will be greatly appreciated, as it is really distracting.

If it helps, I'm using Mozilla Firefox 151.0.2 running under GNU/Linux Debian 13 Trixie as a Flatpak.

Hi whenever I use my Google account to sign into websites (Google, ebay, YouTube, & anyother sites,) Firefox will become unresponsive, the window containing the tab i was using becomes unresponsive, sort of. - I can't click any open Firefox Tabs, - the red 'Close' radio button is greyed-out, so I can't close any tabs or the window - right-click is unresponsive, so i can't close tabs that way, but Command-W closes the tabs normally, but the others are still unresponsive.

- i can open a new Firefox window (with &/or without Tabs,) which works normally.

- & unrelated, but earlier, Firefox was running really slowly, Youtube videos were slowed down, but audio was normal, and scrolling was slow.

When I try to attach file via drag & drop, the Firefox always display "Download file" as attachment. I don't know why because it properly worked before. but after some updates, drag & drop is not working.

The version of Jira at my office is not changed for years(v8.12.1#812002-sha1:7c28d59) and drag & drop is working via Chrome, Edge and etc.

A while ago I made some changes in about:config and also in my ~/.config/gtk-3.0/gtk,css file so as to control my scrollbar and slider -- making them more visible:

/* Log out, and back in for these changed to take effect: */

scrollbar { background-color: #cccccc; } scrollbar slider { min-width: 20px; }

/* dark green: pointer is not in the active window */ scrollbar slider:backdrop { background-color: #00aa00; }

/* green: pointer is in the active window but not on a slider */ scrollbar slider { background-color: #00ff00; }

/* dark red: pointer is hovering over slider but mouse button not pressed */ scrollbar slider:hover { background-color: #aa0000; }

/* red: slider is active */ scrollbar slider:hover:active { background-color: #ff0000; }

/* No effect: */ /* scrollbar-color: blue white; */

... it works half the time. Some pages obey the above settings but other pages continued to show a scrollbar about a mm wide with the slider so faint as to barely be visible. So, in 'about:config' :

widget.non-native-theme.scrollbar.size.override 30

... at least made the narrow scrollbar a bit wider. But how to change it's color? Doing this in a file:

~/.mozilla/firefox/5dqk4533.default/chrome/userContent.css:

html,body{

   scrollbar-color: yellow blue !important;
  }
.... doesn't change anything.  Is there some complete guide to controlling the srollbars?  Nice if it could all be handled in one place of course.

hello my problem is widespread, recently i took my pc to shop because of some system problems, shopkeeper updated my windows 11 to newest version before update i think i had version from before 2025 i think, anyway many old programs i had saved stopped working or started to have problems if they worked, i had to instal new Firefox too because i completely lost the old one, and the problem i had while watching youtube was weird white blinking sometimes, it was very annoying, i searched online for solution and found out that i should turn off hardware acceleration, blinking stopped but now i see weird horizontal line in the middle of my screen while looking at pictures and moving them up or down or watching movie that moves up and down too, i dont mind turning acceleration back on but then resolving blinking while watching videos on Youtube my windows 11 version 25hc GPU Nvidia RTX 3060 driver updated 23.04.2026 version of driver 32.0.15.9636 firefox version 151.0.1

I had experienced the dreaded "XPCom error" and had to do a clean reinstall of Firefox (I know, I should've followed the rule of saving anything important in 3 separate locations.) I had re-logged in and noticed I didn't have any of my bookmarks or anything. Am I out of completely out of luck in this case of trying to get anything back?

I'm on an older, unsupported operating system (MacOS 10.14 Mojave) and am currently using Firefox 115.36.0esr which for the most part works fine. But there are increasingly websites that complain about having an outdated/unsupported browser and won't let me log in or whatever. For some sites I've solved the problem by using the Opera browser, but I've grown accustomed to Firefox, so......

There are a couple of options (that I know of) with browsers based on Firefox: Firefox Dynasty which has now become Firefox Momiji and Pale Moon.

I've given Momiji a quick try and function-wise it seems more or less like the regular Firefox, but does anyone know how safe it is to use? Both in regards to whoever is behind it and as a browser in general? I know nothing about Pale Moon. In addition to working with most current websites and be safe it should ideally be compatible with the current (115.36.0esr) version of the normal Firefox so that I can transfer all my open windows, bookmarks, tabs, passwords etc.

Is there the ability to highlight the open tab on the tab bar above the browser in a different colour this would help as well identify which tab we are working on for example if I am on Firefox, the tab above is highlighted in for example yellow so I’m aware that this is the open tap thank you

On my tool bar, the VPN button seems to have grown... It does this while both off, on and even when i remove/add it to the tool bar. I use very few extensions and i don't know what could have caused it. I use windows 11.

Since updating to 151.0.1 0 on MAC OS Tahoe 26.5 , every 6 digit TOTP entered posts error - "Use another authentication method"

I use same authenticator app on Safari - no issues.
