Firefox Community Forum

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.

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.

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.

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.

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'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?

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.

Hello, I just tried to import bookmarks to Firefox, however they're not appearing on the title bar?

I imported bookmarks to desktop Firefox 134.0.1 (aarch64) on raspberrypios - 1.0, but the title bar only shows Import Bookmarks... and the imported bookmarks are located in Library -> All Bookmarks -> Bookmarks Toolbar/Bookmarks Menu -> Mozilla Firefox -> Imported Bookmark.

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

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.

I am one of those old-fashioned guys who has a title bar on the main window, and inside this (from top to bottom) a menu bar (File/Edit/View etc), then the current set of tabs, then the address bar.

I can click in the address bar and the caret appears, but the moment I start to type anything to edit the URL the address bar jumps up to to the top of the window, covering up the menus and tabs, with a menu of suggested URLs that at times covers most of the rest of the screen. Some images attached to show what I mean.

This started in a recent-ish release -- it didn't use to do this.

How can I prevent this behaviour, so I can just edit a URL in place the way I used to without the address bar jumping to the top of the window?

Currently using FF 135.0 (64-bit), Windows 11.

I can't watch Twitch live stream and videos after updated.When I watching live stream on Twitch, the stream start showing some old tv effect but in colours green. I thought was Twitch problem, then I changed to watch video from my college by using their website. But it still has that effect. But I can watch Youtube videos with no problems. Then i changed to use Microsoft Edge to watch Twitch, surprisingly with no problem. I already updated to the latest version in Firefox. Can anyone help me Please. Thank You

I'm currently using FF 134.0.2 on a Mac running Sonoma 14.6.1. I'm unable to use the Find shortcut (⌘ + f), but I am able to use other shortcuts in Sheets: ⌘ + c, ⌘ + v, ⌘ + Option + m. That shortcut operates as expected on other sites, opening the Find pop-up at the bottom of the browser. It's not working within Sheets to search a spreadsheet or at the browser-level when on a Sheets tab.

Any idea why that one shortcut isn't working?

Since Mozzila updated to 115.23 to x64 Windows there is no longer the abillity to watch Twich live Streamings. Is this going to be permanent ? Should we all leave Firefox after so many years od succefull use and go to Chrome? Are you aware of similar live broadcasting issues ? Wiil Mozzila include a solution soon?

On websites, thumbnails will not display but appear instead as white boxes with small blue question marks. I am using a two year old ipad and my internet speed is 180.

This is a new bug, as of today.

If I click on each thumbnail the image displays just fine, but that is not ideal.

On a reddit forum, someone suggested typing about:config into the search bar but nothing happens when I do that.

Any ideas?
