I've got an Angular project running locally on my machine (https://localhost:4300 using NodeJS 24.11.1 and Angular 20.3.0) and I can't get it to consistently load files for me when I refresh the page.

The network call shows the response coming back, but I'm getting a red ban icon in the Status column instead of 200. Sometimes it's styles.css and nothing looks right. Sometimes it's polyfills.js and I get an error in the console about "In this configuration Angular requires Zone.js". Sometimes, it's one or many chunk-*.js files. Sometimes, it goes back and forth about which it doesn't want to load. And then sometimes, everything is fine. When it fails, it takes between 1 and 20-some-odd refreshes of the page to get it to load properly. The passage of time doesn't seem to make a difference, as sometimes I can recompile the project and jump right into Firefox and it loads fine. Other times, it will only load after I've refreshed multiple times. If it's a JS file that fails, I also see a warning in the console window about "Loading failed for the script with source [filename]".

I've added an exception for the SSL certificate. CTRL+F5 doesn't make a difference in the behavior. The only extensions I have running are LastPass and Bitwarden. The only plugins I have in place are "OpenH264 Video Codec provided by Cisco Systems, Inc." and "Widevine Content Decryption Module provided by Google Inc." I've disabled Enhanced Tracking Protection for the site. I've rebooted and restarted everything.

Any ideas what might cause this? The other developers on the team don't have this issue. I'm using "ng serve --host 0.0.0.0 --ssl xxx-app-name-xxx --live-reload false" to run my environment. What should I be looking for on my machine that might cause this type of intermittent failure?

I am on Linux using Firefox 140.99.0esr.An entry in my name has the wrong state,i cant tell which one.. I cant scroll to the right to fin d it and i would just like to be able to search for bogus entries using a standard text editor

Hello,

I hope you can help me. My Dell laptop crashed, I had to restart the laptop with a Microsoft recovery key. When I opened Firefox I had to log in again with my password. Firefox told me that the password was wrong, I am not sure if I typed in the Firefox recovery key as well. I changed my Firefox password. When Firefox opened my bookmarks were gone and I can not find backup file when following the Firefox 'import bookmarks' link in the bookmark bar.

Thank you!

Hi, The versions of Firefox since Feb 2026 have been extremely memory hungry on Windows 10, even though I have the option to restore tabs on demand set to TRUE in the config.

The memory hungriness has got so bad now that even on my 16GB machine, about once a week I find that my computer has suddenly run out of memory without warning and my entire screen goes black (not just within the Firefox window, the entire screen). When the computer gets into that state I am unable to use Ctrl+Alt+Del to get back to Task Manager, and the only way out is to hard-reset my computer.

This means that whenever I want to do anything else remotely memory hungry, such as running my research code, or a game, or a Zoom meeting, I have to kill Firefox first. But I sometimes even end up with black screen when trying to use Word or Excel alongside Firefox.

Essentially, Firefox is becoming unusable on my desktop, and its bookmark feature is borderline unusable on mobile now since the update a month ago made it impossible to change which folder I save my new mobile bookmarks in.

So if I have two more black screen clashes I think I will give up using Firefox entirely after being loyal to it for about 15 years. This is extremely disappointing.

I linked Google to open when I enter my Firefox browser and I want to delete Google and learn Firefox but I can’t get out of Google. How do I unlink it. From where ?

bold textEvery time I start the cimpouter I lose my bookmarks how can I avoid this issue. Each time i takes about two hours messing about to get them back

Switched on vertical tabs in the latest Firefox release (149.0.2) and noticed a bit of an annoying issue with the bookmark toolbar. If setted only on new tabs - it push all ui of vertical tabs down, and when you switch - it's going up again. I’ve attached a GIF to show what I mean.

I’ve enabled the option to show the bookmark bar only on new tabs, along with the vertical tabs setting. This behavior doesn’t seem right to me — I’d expect the bookmark bar to sit beside the vertical tab sidebar without shifting it. The current design is pretty frustrating.

Is there any way I can fix this? I think it's a clear bug in UI. Thanks!

Seit kurzem kann man in der WhatsApp-Web-Version keine Bilder mehr einfügen. Es erscheint nur ein schwarzes Feld. In Chrome und anderen ANDROID-Geräten funktioniert das. Nur nicht in Firefox. Die WhatsApp-Hotline schreibt, dass es an Firefox liegt.

Pages stop on Youtube. Videos won't start or stop after a few seconds. My first choice in browsers has become so unreliable I may be forced to stop suing it after all these years.

Hi,

I'm unable to sign in or create a new Firefox account with my email address hyeok@cv-3.com. I keep getting the error: "Primary account email required for sign-in."

Here's what happened: 1. I previously added hyeok@cv-3.com as a secondary email on my primary Mozilla account (ground4ekd@gmail.com). 2. I later removed it from the secondary email list. 3. The secondary email section on my account settings now shows "None." 4. However, when I try to sign in or register a new account with hyeok@cv-3.com, I still get the "Primary account email required" error.

It appears that Mozilla's server still associates hyeok@cv-3.com with my primary account even though it has been removed. Could you please fully disassociate hyeok@cv-3.com from ground4ekd@gmail.com on the server side so that I can use it independently?

I'd like to be able to use hyeok@cv-3.com as an independent account. Any help would be appreciated.

Thank you.

A while ago when using the setting firefox noticed that i was using a vpn and turned the settings off. At least that was what i believed. Turns out, that only works with browser vpn addons that use the firefox settings. But these addons do not use wireguard, but tls to encrypt your data. If i use a vpn, and want to use the dns settings provided by them, i have to turn of the feature the dns over https feature from firefox. I only want to use that feature, if im not "protected" by a vpn solution of my choice.

For some weeks now, the "File" menu randomly opens by itself then closes a second or two later. It seems to happen once I get focus on a page. For example, if I open a new tab then go to Google and ask a question, once the answer is returned, within a second or two the File menu drops down then closes again. I have the latest version of FF (149.0), 64-bit under Windows 10. There are a couple of settings in about:config that were suggested to be changed by ChatGPT but this hasn't made any difference.

I use Firefox. However, in the past month, every time I print an e-mail from Yahoo Mail, it appears as "PDT" (correctly), but when I press "Print" it converts the time stamp to "UTC". I don't want this, and don't know how to stop this.

Hello, I can't play rise of cultures on my browser. Other browsers works fine, I Have problems with firefox only. The game starts working properly, but in few minutes all buttons dissapear. Please help.
