I accidentally pressed a lot of keys on my keyboard and for some reason the default colors of Firefox have changed. I found out that by using Ctrl+Alt+D that I can switch the colors back to normal or to the colors that now appear automatically, but this only works for one tab. If I open a new tab, it shows the weird colors (see images below). I tried looking up specific shortcuts for Firefox considering the shortcut mentioned before (Ctrl+Alt+D) only works on Firefox. But I can't find any shortcut tied to that combination. I'm unsure what to do and how to fix this.

I would appreciate it if someone could tell me how to fix this.

I am tired of this [removed] browser quitting, even when I don't have it open...I am going to uninstall it and NEVER install it again...I tried a full uninstall to see if it would fix whatever the [removed] issue with it was, but it is doing the same [removed] again!...I don't have this problem with any other browser I use on my system (Chrome, Brave, Opera and Tor)...I am tired of dealing with this [removed], so you can just take your [removed] and shove it!!!

How the hell does a browser crash when it isn't even being used???!!!

No need to respond and ask for any logs or other [removed], because it will all be gone!!!

Hi,

Firefox Developer Edition 126.0b7 (64-bit) shows a perpetual "Loading" screen when trying to access my internal Logitec Media Server at 127.0.0.1:9001.

Other browsers like Waterfox Classic have no trouble, so LMS is working fine.

I tried cleaning the cookies, disabling the firewall (Windows 10), that did not help/

Any idea how to solve this?

Thanks.

I just switched to Windows 10 from Windows 7. Firefox was working fine, but now many or most pages are garbled; see screen-capture fragments at http://www.fenichel.net/firefox/. I tried a new Firefox 64-bit, but it crashed on most pages.

Hello, I have problem with firefox. When I try download from facebook page files .docx, .xlsx (Microsoft Office) Firefox automatically download it as PDF and file is broken. I don't know how to repair this. Please help, it is very frustrating.

As of an hour ago suddenly all of the usual suggestions and autofill with bookmarks in my address bar are wrong and out of order. I didn't close out of or update Firefox, I was just browsing online. I didn't change anything in my settings or have opened that up in days at the minimum. I cannot figure out how to either revert back or tell Firefox to not show me these choices so I can get my old ones.

I'll give an example: When I typed in "ma" it would show me mangadex.com, which I often go to. Now when I do it not only is 5th on the list it shows up and fills in "https://www.manticgames.com/", which I don't have that specific page bookmarked. I have "https://www.manticgames.com/games/kings-of-war/" bookmarked, but not that homepage. But now all of a sudden it is showing me the homepage of that site when I begin to type in "ma".

This is incredibly irritating and I have no idea why it's doing this at me out of nowhere. I don't want about anything showing up besides my bookmarks and specifically only the pages I bookmarked.

I just added "TextArea" to my extensions & it only can be selected by clicking on the picture puzzle icon at the right edge of the address/search bar for a dropdown box of extensions. I would like to display it and a number of others now only on the dropdown on visible toolbars, but can't move them there. When I select "Customize," it shows some basic icons not being displayed, but only the basics and does not include extensions I've added recently. I used to keep icons in the All-in-One Sidebar on my left margin, the Vertical Toolbar on my right margin & the bottom Status bar in pre-version 57 FF and don't want the extra hassle of having to use the dropdown for commonly used extensions. How do I get these icons moved into an existing visual space on my browser? I have 3 36" HDMI screens & plenty of real estate to play with, but no way to use it in FF for new extensions. Do I have to continue to use alternatives like WaterFox Classic & Pale Moon?

Hello,

I've just downloaded firefox, making the switch from chrome. Doing so I've migrated a couple of tabs and extensions I had. Totally it was 50 tabs, with 6 extensions, I've downgraded now with the switch and it's only 37 tabs and 2 extensions, even so firefox is using more ram than google by a large amount. With 50 tabs open, chrome was using 1.5gigabytes of memory. With the same 37 tabs and extensions, firefox is currently using 6 gigabytes of memory.

The tabs used are from reputable sources, so firefox shouldn't be breaking on these websites. The extensions I am using at the moment on firefox is, Ublock origin, Dark Reader.

As far as reputation goes, firefox should be using less Ram than chrome. Is there a setting I should know about to lower such performance issues? Firefox acceleration is ON.

Thank you for any answers.

Possibly there was an auto update of MOZILLA FIREFOX on our DELL LAPTOP (Windows 11). Now, we cannot get a Mozilla window to open - due to error message:

XUL Runner Error: Platform version '118.0.1' is not compatible with minVersion >= 118.0 maxVersion <=118.0

Can someone please help us get back to a previous version of Mozilla Fire. Perhaps it is a Windows error. I have no way of knowing. Please help me. My email is: [removed email from public] Thank you.

I recently installed new pc with fresh Firefox Developer Edition. Then I transfered the profile folder from old pc to the new pc. All bookmarks, addons, etc is there. Just the XULRunner popup appears only on the new pc. I uninstalled firefox on the new pc again and reinstalled it with profile cleaning. After profile cleaning firefox got faster and addons got removed. But the XULRunner popup keeps appearing. When I go to taskscheduler and trigger the "Firefox Developer Edition Background Update CA9422711AE1A81C" again, the XULRunner popup appears. Removing this taskscheduler and Firefox keeps readding it and the XULRunner popup are back. Any idea how I can get rid of the XULRunner popup?

How can I completely remove the tab bar and regain 3/4 of an inch of screen space. It would be nice if Mozilla would just have a on/off button for it. I've tried creating a folder called Chrome within my Firefox Profile folder. I then created a text file within that folder and named it userChrome.css. I put this string in the text file #tabbrowser-tabs { visibility: collapse !important; } This did not work, does anyone know the best method for getting rid of the annoying tab bar?

Thank you

A website MultiSafepay.com has saved my CVV number in Firefox.

How do I edit the autofill data?

I can't get to the same payment page, to be in a position to delete it.

Most links on this matter refer to:

 Options => Privacy & Security => Forms and Autofill

However in my Version: Firefox 98.0.1 (64 bit) running on an up to date Windows 10 this feature is missing or deprecated.

Can anyone say how I could edit/delete this specific entry, or point me in the direction of where this data is stored?

In the mean time I can't recommend using Firefox for entering critical security data, where websites can allow the storage of CVV numbers.

When I am watching a TV stream on my PC; when I hover on (some) pictures or videos, a supremely annoying pop-up url appears at the bottom of my screen. I have some learning problems and can not figure out the 'userChrome.css' method. I can not work with long streams of multiple overlapping instruction. I am not tech savvy. I do not understand 'layers' and stuff like that. I can do the 'about:config' thing, if anyone knows whether or not if I can fix it from there, I would be eternally grateful. Thanks.

How do I create a TLS 1.0, 1.1 exception in Firefox 100.0+ for my legacy devices (NAS), that no longer get firmware updates from the manufacture, that are on my private network and thier configuration is done through a web browser?

 I have been using Firefox browser for a long time, since it was called Mozilla browser.  An answer such as "I'm out of luck." means I will have to look for a new browser.  I prefer not to do that.  I trust the Mozilla brand and like you products and recommend them to my friends and customers.

I'm a little surprised they've taken away the option of choice when it comes to downloading files. But what's most annoying, is the manager opens u and drops down blocking my view of the page, much less that it makes ms stop and think about what I am about to download.

I do not understand the purpose of this. The old way was safer, cleaner and less annoying. How can, or am I able to get that "choice" back?

When searching for a fix I have seen that that there is/was a similar feature in the Edge browser but it can be undone. I feel Firefox users deserve that option.

Thank you.

Thank you.

Hello How to remove extension symbol from toolbar? ^(see image): https://i.imgur.com/2bh8se5.png Any idea? Thanks

Hello all. Since the update to Version 113.0 I have been getting an error in my Event Viewer which is Event 2 Firefox Default Browser Agent . I am now on Version 113.0.1 and still get this error. Firefox is my default browser. Below is an image of what I see in my Event Viewer and also the full view of the event itself. I seem to not be having any problems with the browser but I was wondering if anyone could shed some light on why this is happening or forward to the Devs.

Respectfully, Don
