Windows Updates (KB5035845) and 10.0.19041.4163

After these latest updates, EVERY, Firefox browser (derivatives included, i.e. LibreWolf, etc...) are opening VERY slowly. Its almost like the browser is freezing while opening for around 10 - 20 sec, then opening. It used to open within a second or two. If I uninstall the updates the problem goes away, BUT, windows re-installs them automatically. After it is up and running its ok. The problem seems to be on startup only.

I Have used Firefox as my main browser for a long time. I've also played the games on pch.com (Publishers Clearing House) for years. About ten days ago, I started having problems connecting. The error messages have changed a little each time, but still no access. I've also tried Chrome and Edge, and still no access. Today, I tried to access on my phone and got a 'site is not secure' message. Any idea what's causing this or what the problem may be? Have you heard about changes to the pch.com website? I can access the site if I turn off my ISP connection and use a data connection. My ISP is Optimum. Looking for any guidance. Thanks.

Firefox freezes - energy efficiency? Version 124.0.1 (64-bit) Windows 11, version 23H2

Firefox has been freezing up completely, all windows and does not unfreeze if I wait, if I click "wait for Firefox to respond" it will pop up again immediately, no matter how many times I click it.

I associate this problem with the new "efficiency mode" that shows two green leaves by some of my firefox processes. The pop-up by the icon says it's to "limit resources used by the process" which suggests the cause is limiting access to necessary resources.

I have found no way to disable this unwanted "feature" - although I am all for eliminating carbon emissions, I need the browser to work.

When this happens immediately after restarting Firefox, the "restore previous session" is gone, so I lose a ton of open work.

If I try ending processes one by one, focusing on the green leaves (not all have the green leaves icon), I invariably close the last window while many other processes are present, losing ability to restore history.

I have written Windows help with no response. (This seems suspicious, as a way to disable competitors.)

I do not see this happen in Chrome.

PLEASE: 1) Provide a way to restore history from previous session (e.g., all windows in last week? or recent instance?) 2) Solve this problem - is it the "energy mode" setting?

As a index.html cannot be found on HTTP server as DNS A record doesn't exist, use AI to build a static HTML page we call these Go Pages from a template 'Config'

This means that AI generates HTML / CSS / JS instead of a web server returning a list of files from ITs disk.

Now we have No DNS Web ?

I'm having a problem logging into one of my banking sites. I talked to the bank tech support yesterday and did a password reset. There was nothing wrong with my old password. That worked yesterday but today I'm back to the same problem. It won't log me in.

I deleted cookies and cleared cache but still not logging me in. I tried another browser (Edge) and got right in. In Firefox, I use private mode to log into financial accounts but I also tried the regular browser and still won't let me in. This is the only account I have a login problem with. It did work after the password reset if that's a clue but I don't want to have to do that every day just to check my account.

Here is the site:

https://www3.citizensbankonline.com/efs/servlet/efs/login.jsp

I need a fix for this. It's very inconvenient and it is the only account I have a problem logging into with Firefox.

Thanks for the help.

I have moved to another password manager, and would like to completely remove my saved logins from my Firefox account and stop using the auto-fill, auto-suggest feature. However, no matter how many times I delete my passwords and Sync, they keep appearing in my Android Firefox app. I have cleared the app Storage and Cache, I have reinstalled it from scratch, but no matter what I do they reappear. My (also Synced) PC on which I deleted the passwords has not shown it again since I deleted them there.

I just want to completely delete all my logins in my Firefox account, permanently and across all my devices. How can I do this?

Hello Mozilla Support Community,

I'm an aspiring web developer diving into the world of Firefox add-ons to enhance my workflow. While I'm familiar with some popular add-ons like Firebug and Web Developer Toolbar, I'm eager to explore more tools that can streamline my development process further.

I'm particularly interested in add-ons that aid in tasks such as:

Code Editing: Are there any add-ons that offer advanced code editing features within Firefox, such as syntax highlighting, autocomplete, or code snippets management?

Page Inspection and Debugging: I'm looking for add-ons that provide robust tools for inspecting and debugging web pages. Something akin to Firefox's built-in Developer Tools but with additional features or customization options would be fantastic.

Performance Optimization: Are there any add-ons geared towards optimizing website performance, such as identifying and resolving bottlenecks, analyzing page load times, or minimizing resource usage?

Cross-Browser Testing: I'm curious about add-ons that facilitate cross-browser testing within Firefox, allowing me to preview and debug my web projects across different browsers without leaving the browser window.

Accessibility Testing: Given the importance of accessibility in web development, I'm interested in add-ons that assist in testing and ensuring web accessibility compliance.

Version Control Integration: Lastly, I'm wondering if there are any add-ons that seamlessly integrate version control systems like Git or SVN into Firefox, providing convenient access to version control features directly from the browser.

If you have any recommendations or personal favorites in these categories or any other add-ons that you find indispensable for web development, I would greatly appreciate your insights. Thank you in advance for your help and expertise!

I'm using the Firefox browser for Android. When I'm on Bluesky with my Android phone and go to create a post, I tap the image to upload an image. I get the post editor box on the top, the keyboard on the bottom. When I tap the image to add a photo, the keyboard disappears leaving only the box to edit the post and it doesn't go on to the next step where I would choose the image I want to upload. I'm using Firefox for Android 124.0 and a Galaxy A53 5G with One UI 6.0. Android version 14. Also, I have it set to use Spanish.

Hi,

I noticed that the shortlinks/websites on my startpage (the House icon) are placing cookies as soon as I start Firefox. Not all of them and also in a random manor. This does not happen in Private Navigation, which i almost never use.

For me this is rather strange, I do not visit these shortlinks and already being tracked by those cookies. How can this be changed?

My settings are to clear all cookies and history at closure. Subquestion: Do I need to choose Options/Close or does this also work by clicking the X in the right upperhand corner to close Firefox.

Hope someone can shed some light... Lasco

Additionally, I'm interested in learning about any potential privacy considerations I should be aware of when using this feature. Any advice or recommendations would be greatly appreciated.

New computer, new install, when trying to log in to my account to set up sync/migrate, Firefox claims the password is incorrect ... the same password I just used on this (old) computer to log in and ask this question!

I've had issues with this before, when I synced up my phone. Took several attempts to log it in.

Also, tried changing password, but for some reason it won't accept a new one? (That's different issue. Would prefer to log in with current password. at least)

Thanks!

When I open firefox it is fine, then ads, buttons, means of surfing then net opens new windows (according to task master) and never closes a window. So once I'm into a game or web site, it's taking over half of my memory (showing like 11 firefox windows open). I can't play any of my games, even minecraft (which is odd). This didn't happen til this last update. Right now I'm stuck at home mending a broken hand, so I kinda need my browser games where I only use my mouse. If there's an easy fix, I'd really like some help in fixing this issue please. Thank you, Lisa Pearson

A certain set of plaintext files are rendered in a weird way when opened in Firefox.

Some plaintext files are rendered "MS Gothic", which is the default monospace font for plaintext files in Japanese encoding. (Also, if I change font.name-list.monospace.ja to "monospace", the font changes).

However, the files are not in Japanese encoding, they do not contain a single character in Japanese encoding. Since the files are local, they have no HTTP headers to determine the encoding, so Firefox must have guessed the encoding somehow. How can I stop firefox from detecting those files as Japanese while they are not?

Also, I noticed that this issue happens only with long files. The shorter a file, the less likely it is that Firefox renders the file as if it had Japanese encoding.

Since I cannot reproduce the issue with smaller files and the files contain confidential information, I am unable to provide a minimal reproducer.

As a workaround, I could change font.name-list.monospace.ja, but this would change (potentially break) rendering of Japanese websites.

I'm using Firefox 124.0.1 on Windows 10, although this issue has been present for at least some months (at least 4 firefox releases).

The screenshot shows an excerpt where the text "C:\Temp\2024-" is partially rendered with Japanese glyphs and fully rendered with "MS Gothic" font which is hard to read with ASCII characters.

PS: I [censored] some of the information in the "Troubleshooting Information" field below.
