Firefox 136 broke my custom new tab page, how do I fix 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?

Every so often for the past few days this "unfinished" program window has appeared on my pc on top of a normal Firefox window (see attached png). Does this have something to do with Firefox? I think the same thing appears when I first open Firefox, then it gets "filled in" and appears as a normal Firefox window. I am running Firefox 133.0.3 (64-bit) on Windows 10 Pro Version 22H2 build 19045.5247 Windows Feature Experience Pack 1000.19060.1000.0.

I use Firefox 134.0.2 (64-bit) on Ubuntu 24.04.

Some (not all) web sites show up only after a delay of exactly 30 seconds. The attached screenshot shows that this delay is due to DNS resolution. This behavior is reproducible by simply closing Firefox, opening it again and entering the same web site once more. Once this initial delay of 30 seconds for DNS resolving has passed the web site can be browsed normally.

Using Google Chrome, Opera or even the Tor Browser on the same system works without any significant delay. Also a DNS lookup from the console returns data almost immediately.

As the delay is always exactly 30 seconds this looks like some DNS resolver timeout only showing up when using Firefox.

Neither starting Firefox in Troubleshoot Mode nor (as often suggested) disabling IPV6 for DNS by setting network.dns.disableIPv6 to true did help.

Any idea how to fix this 30 seconds delay?

Many thanks for any help, Felix

I use several browsers and when it comes to functionality I consider FFox to be the best however with 1 major drawback - it's speed / lag issues which is why I stopped using it as my primary browser and only as secondary one

I can have 2 different Chromium based browsers open simultaneously and while this impacts the performance somewhat if I open Firefox and another browser responsiveness grinds to a halt (sometimes even crashes)

Even just starting Firefox by itself takes 5x as long as other browsers

So I'm wondering is Firefox just more resource intensive or is there something wrong with my setup?


The main difference between my Firefox install and my other browsers is the number of Bookmarks (10000s) due to me having it installed for much longer so is it possible for a large number of Bookmarks to slow the browser down even when not open ?

Other possible causes I read elsewhere are 'Cookies and site data' (currently around 50mb)

I clear the 'Temporary cached files' & 'Browsing history' on regular basis so they shouldn't be an issue


The add-ons I have installed are NoScript , Ublock Origin & Firefox Color


In regards to troubleshooting is it possible to install a 2nd install on the same system simultaneously without overwriting the current one ?


Thanks

Running Firefox 133.0.3 on Windows 10 22H2

The last week or so, when I try to download my photos from iCloud, Firefox blocks the download, saying it contains a virus or malware. Of course it does not - it's a zip file of screenshots! Running a scan on the folder once unzipped confirms there is nothing malicious in it. Can you fix that please?

Windows just had an update, in that when I did it now Firefox has no sound at all in Youtube, Disney plus or any other site.

Now I did my own trouble shooting, games have sounds, my music player (winamp) has sound, I downloaded chrome and I oped volume mixer and played a video in that, there was sound.

I do the same thing in firefox and there is no sound, and in volume mixer where the lines go up showing the volume as it plays, it did it for chrome but not Firefox.

So there is no issue with my head set, my computer or my sound, it is firefox alone.

Hi,

I am the developer of the Dictionary Anywhere extension which is a Firefox recommended extension. Recently my extension stopped performing up to its expectations due to backend changes in public API that it uses to find meaning of the words.

However, I am unable to modify the code of extension to fix the issue as I am not able to login to my account due to it being behind MFA, and I have lost access to the phone which contains those MFA codes.

Can something be done here, to allow me to update the extension to rectify the issue that 50k users who use this extension regularly are facing? For example, can the extension be transferred to another account through which it can be updated, lots of users are suffering as the extension is not working. I have access to the source code of the extension .

Thanks and Regards

Hello all,

Ever since an update to Firefox from a few weeks ago, I have been having issues with white backgrounds displaying incorrectly in Firefox. I have attached two identical images from the NYT homepage: the first is a screenshot from Chrome and the second is the same exact image but taken from Firefox.

I have also attached another screenshot taken in Firefox from REI.com. You'll see that it's not necessarily just a white background that is causing the weird blue color. It also happens in products images being displayed incorrectly.

I figured this might be a Firefox website appearance setting, but I have played around with it and selected many different permutations and I haven't been able to solve this issue. I have also tried refreshing Firefox, using Firefox in Safemode, disabling all of my plugins/themes, etc. and nothing was fixed.

I am pretty sure this isn't a system wide issue or a monitor issue because these websites are being displayed 100% correct in Chrome and Edge. This is only an issue in Firefox.

Can someone advise?


Thanks,

DC
