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!

So I understand this: https://support.mozilla.org/en-US/kb/xframe-neterror-page and the reason it exists, but I need to find a way to turn it off because it's literally blocking me from accessing the Library of Congress webpage inside the same browser for my job. It's not a malicious site, but I can't figure out how to tell Firefox to stop blocking it as if it was a malicious site.

Help.

I have Firefox's New Tab set as my home page, since I'm choosing to divorce myself from political doomscrolling for the next four years. The New Tab page is perfect for having frequently visited sites at the top, Pocket stories I can curate in the middle, and what used to be a history of articles and sites I've read most recently in "Recent Activity" along the bottom. Within the last few days, "Recent Activity" has been blank, and will no longer keep track of articles I've recently read. I've tried clearing the browser history and cookies, and it came back for a moment, but quickly went back to being blank. And the major downside to clearing the browser is that my four rows of most frequently visited sites gets wiped clean also, and I have to spend time getting them back on the list. I do not have Firefox set to automatically clear history upon closing it. I've tried turning "Recent Activity" off and on with the page's Settings (cog in the bottom right corner). I'd really like to have this back, as it can help me find recently read content (especially Pocket content) easier than wading through the History log. Any help would be appreciated.

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.

I use the IRS form filler to pay my taxes...have for years with Firefox browser. This year (for 2024 return) when I sign into the site the 1040 form does not display correctly. the boxes are to the right and below the actual placement. I emailed IRS who said it is a setting in Firefox. I tried the site using Microsoft EDGE and it displays correctly. I have searched for possible solutions and tried them all like using/on and off excelerator, letting Firefox chose size and colors of sites, turned off Noton etc. I posted another question here but no replies or looks so maybe I did something wrong so I will try to post again. I have W10 fully updated and Firefox too up to date. I understand I could use Edge but never had to and prefer to use Firefox as I have before. any suggestions would be appreciated or where I can report a possible issue with Firefox. I have attached a sample. thank You

I have a message "Your browser is being managed by your organization." in "Settings" (about:preferences). 4. In "about:policies" I have DisableFirefoxAccounts=TRUE. 5. in "about:config" identity.fxaccounts.enabled=false and grayed out.

Please help me to turn on the sync of bookmarks. All these listed issues obviously have something to do with it.

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?
