iCloud has stopped signing in on the Firefox browser for Windows. I contacted Apple Support and they told me that this is an issue on Firefox's part, and told me to try signing in the next morning and they guarantee it'll work. It did not. In fact, it has been over a week, and it still does not work.

When I enter my Apple ID and Password, the website gives me an error "Failed to verify your identity. Try again." The website does NOT send me to the 2fa screen, yet it still sends a 2fa code to my iPad nonetheless.

As Apple has said this is an issue on Firefox's part, I am posting this here. Attached is a screenshot of the error.

Hello,

Suddenly some UI elements became color-inverted or almost completely black, such as the tab icons in the tab bar, the website icons on the New Tab page and some icons in the settings menu. Also, some websites appear to have this issue, but the Samsung website is the only one I found so far with this issue.

On the same day it happened I switched to an OLED HDR-capable monitor, so I assumed it would be related to HDR, but I played around with some settings and I'm not sure anymore.

What I tried: - hardware acceleration on and off - HDR completely on and off - default light theme and dark theme, no customs themes installed - all extensions disabled (I have no extensions that would influence graphics or colors anyways) - latest update already installed - nothing else changed in the Nvidia control panel as far as I remember

None of the above helped. Any advice on this is appreciated. Attaching some pictures with the issue. Using Windows 11.

Thank you!

I don't fully remember when this happened, but lately the browser has trouble clearing my search history even though I had it set so that it does so every time I close it. I only managed to fix it by making it so that it doesn't remember the search history, but some of the old searches are still there whenever I punch in part of what I was searching.

The new native tab group feature has an option to "Save and close group", implying that you can restore the group. But doing this, you will find that the group disappears.

Is this a known bug? Has anyone figured out how to restore a saved tab group?

On Feb 13th I went to my website at MyHeritage.com, to which I'm always logged in, to find that a few seconds after it loads it becomes all greyed out and I can't access anything. I had been on the site a couple of weeks earlier with no problems.

I removed the "Enhanced Tracking Protection" and I turned off AdBlocker for the site but the problem persists. I have logged out and then logged in - same problem. I turned off my computer and restarted it - same problem.

When I went to log in to my account at MyHeritage using my Chrome browser I encountered the same problem of a greyed out page BUT there was a banner stating something about cookies and when I clicked the "I understand" button the greyed out page cleared and I was able to access my account.

However, Firefox is my default browser and I want to be able to access this page using Firefox. It seems to have something to do with cookies.

Recently starting having the issue where some whites and the tab icons appear washed out and even glitched out and pink when using my PC. I haven't made any significant changes to my system as far as I recall.

Colours in other browsers and applications are effected. Going to the same webpage on both Brave and Edge shows the whites correctly. On all the games on my PC there are no glitches in colours.

I have tried a few fixes already: -Removing and re-downloading GPU drivers - Fixes the issue temporarily. After about 1 day the issue comes back. -Re-seating the GPU - No fix. -Turning off colour override in Firefox - No fix. -Uninstalling and reinstalling Firefox - No fix.

If anyone has an idea or knows the setting that may be causing this problem I would really appreciate it.

Can’t launch Firefox 3.5.19 on Linux Ubuntu When trying to run with:

./firefox

Terminal gives the following:

./firefox-bin: error while loading shared libraries: libdbus-glib-1.so.2: cannot open shared object file: No such file or directory

For years I have been able to watch a foreign TV website, despite having only a DSL connection (I allow only the scripts essential to make it work). Since I did the last update, to 137.0, I cannot watch either the live stream ("General source error") or old programs ("There is something wrong with your internet connection"). This is absolutely consistent; I've lost count of the times I've tried.

I never had problems like this before. At worst, if Windows was running a background process I might have to stop it to keep from having pauses in the program. All I can think of is that you did something in the new version of Firefox that has made video impossible on DSL.

After Firefox updated today, the executable no longer starts. I get the following error message:

firefox.exe -- Bad Image

C:\Program Files\<mozilla firefox\gkcodecs.dll is either not designed to run on windows or it contains an error. error status 0x000000d. < p></mozilla>

And then another error message: Couldn't load XPCOM.

Please advise.

Win11 Firefox 138.04 It appears some of the shortcuts on the Newtab page are preloading somehow.

Where are these coming from? Sidebar is off. I have all preloading off, all suggestions of every sort off, any predictive anything off.

I am not experiencing this on my win10 machine.

How do I stop this?

Hello. This question concerns the Windows 11 desktop version of Firefox.

I have long used the Home and End keys on my extended keyboard to scroll to the very top of any given page in Firefox (Home) or to the very bottom of that page (End).

But, lately, I notice that, for no reason I can figure out, Firefox no longer responds to those shortcuts. Now, when I tap Home or End, the page may, at first, scroll up or down slightly but not to the top or bottom. If I press Home or End again, nothing happens at all.

Sometimes, if I press Ctrl + Home simultaneously or Ctrl + End the page will scroll to the top or bottom respectively.

Why has Firefox's behavior apparently changed? Is there an issue with my keyboard or operating system settings? (I use a Logitech G915 keyboard.)

Please let me know how to restore Firefox's shortcut functionality, where I can tap just Home to scroll to the top of a page or only End to scroll to the bottom of a page.

Thanks and be well.

I'm on Linux.

I've been using this method to setup a custom new tab page for Firefox for almost 4 years, and it has worked great: https://jamesnorth.net/knowledge-base/article/firefox-new-tab-page

---

Navigate to /usr/lib/firefox.

Create autoconfig.cfg:

// var {classes:Cc,interfaces:Ci,utils:Cu} = Components;

/* set new tab page */ try {

 Cu.import("resource:///modules/AboutNewTab.jsm");  
 var newTabURL = "file:///home/james/ff/index.html";  
 AboutNewTab.newTabURL = newTabURL;  

} catch(e){Cu.reportError(e);} // report errors in the Browser Console

Create defaults/pref/autoconfig.js:

// pref("general.config.filename", "autoconfig.cfg"); pref("general.config.obscure_value", 0); pref("general.config.sandbox_enabled", false);

---

However, upon updating to Firefox 136, I only get a blank page. All of my autoconfig files still exist in /usr/lib/firefox.

When I create a new tab with Ctrl+T, it's a blank page. When I create a new window, it loads the local page I want it to load with the file path in the URL (which it never had before; the URL bar was blank in Firefox 135). So it seems to be partially working.

Any tips?

Trying to browse ebay using Firefox. The pages have become really slow when loading.When scrolling down the page is blank then slowly populates as I scroll down the page. I've just tried microsoft edge and there is no problem.

Firefox has stopped obeying target="_blank"

Started a month or so ago.

Take a look at Firefox target="_blank" problem for details.

There is not a topic in the dropdown list that remotely addresses this issue so I just selected Performance and Connectivity for the hell of it.

Hi. There is a new feature of Firefox that bothers me. It is when I drag tabs around the top, they try to group when I don't want them to. So I go to about:config and find the "browser.tabs.groups.enabled" key and set it to false. But when I restart Firefox, the change reverts. How do I fix this so the change stays?

I've already tried going to Menu->Help->More troubleshooting information->Profile Folder->Open folder, but there is no "user.js" file there. Do I have to do a Firefox reset to fix this? I hope not...

Note that I'm pretty sure that other settings that I change do not revert when I restart Firefox. Right now, it seems to be just this one about:config setting, unless the new version of Firefox reverts all manually changed about:config settings upon restart.

Thanx in advance for any help.

I tried to do the fix using userChrome.css but it just didn't work. Am I doing something wrong?

Also the fullscreen animation fix using the about:config settings doesn't work either.

Thanks in advance :3

the tab groups feature doesn't work. WHen i drag one tab onto another, nothing happens, other than the tabs go back and forth. Can't put one tab over another and no group is created.
