what have you done with the? "new" firefox since the last update and change, it crashes, it won't open websites and now it said prove you're not a robot and other miscellaneous things are going on? Can I go back one update? I dislike what you have done. Firefox has always been my first choice and not Chrome, I'm going to have to find another search engine.

I'm talking about Firefox version 156.0 (64-bit)??? So since the last Windows 10 security update Firefox just wouldn't start anymore. I had two or three automatic refreshments of Firefox but even that didn't do the trick anymore in the end. Then there was a secundary Windows 10 update and I got everything running smoothly again for two days, and now today there was a Firefox update and the whole trouble started again. Even some sites wouldn't work anymore (outlook, DeepL) or I couldn't login anymore. I'll try going back to a previous version ...

Hello I've been a Firefox user for decades; recently a problem suddenly appeared that I'd never encountered before; I mentioned it to you but you didn't see fit to reply. I have twice 'repaired' Firefox, to no avail. After hours of Internet research, I've discovered the nature of the problem: it's called FirefoxCP Isolated Web Content. According to the many forums I've consulted, you're perfectly aware of it. So I don't understand : - why you don't take the trouble to reply to a user with a problem. - and, above all, that you're perfectly aware of the problem and don't do everything in your power to solve it. As 'killing' an activity in my Mac's activity monitor every ten minutes is rapidly becoming unbearable, I'm going to have to change my browser, much to my chagrin. Farewell dear Firefox!

My twitch website tweaking, youtube tweaking then sometimes the home page is tweaking things are very glitchy and what not. i love firefox cz its open source but these wearid issues kinda make me always switch back to chrome from time to time

Why is the sessionstore.jsonlz4 generated from a private firefox window ? It is not private anymore if the session is stored in place of the regular session, which by the way happens not to be generated when the regular firefox window is closed while a private firefox window is still open. The private firefox window should have no effect on the regular session storage and should never be stored, all this is very confusing.

Mozilla Firewall was running with no issues on my Win11 v25H2 laptop until about a week ago. Since then, the program won't open. I've tried launching it from the install directory as admin, or from the Mozilla browser extension. The Waterfox Mozilla Firewall extension (v1.35.0) opens, but there's no response when I select "Open Mozilla Firewall."

One note is Mozilla Firewall is listed as a Task Manager Process. I ended all instances, but no change.

I've also: Uninstalled Mozilla VPN and deleted the install directory. Downloaded a new executable file and installed. Restarted and powered off the laptop. Windows Updates are current. Checked Event Viewer for Mozilla Firewall errors, but none listed.

Thanks, Ben

to get access to my bank account via Firefox the bank should send me an access code on my mobile. The page pops up on Firefox, I wait for the code but there is nothing coming onto my phone? I can access my bank via a different website so am wondering if there is a problem with Firefox. By the way, my mobile functions correctly and I receive calls.

The Firefox browser does not function now. I thought I had to update, got an error - Couldn't load xpcom and an entry point error, I have no clue what to do.

firefox is my default browser' i use Win 11 never had an issue before with Firefox *Email hidden for privacy*

In daily work tasks, I end up with a large number of windows and tabs open. I am wondering if this is not adding to my extremely slow recovery of frozen tabs and windows and MANY instances of "Non-Responsive" everyday. Firefox is set to allow multiple processes, naturally, but I'm looking for ways to ease the pain here. If I disable Multiple Processes in Firefox v138.0.1, will I have problems running, for example, 5 windows with a total of 30 tabs spread across those Windows? (God knows I don't wanna have to grow up and actually manage the things I open up for stuff.) In addition, I am running Canva, sometimes Paint 3D, and Office 2021 concurrently. An associated question........in this most recent Firefox, how do I run Multiple processes, but limit the number of them to 5, for example? There used to be a setting in Firefox to do that, but I can't find it. I'm working with Windows 11-v24H2 on a Dell Inspiron 17 with an Intel Core i7-8550U CPU (about 7 years old) and 16Gb of Ram.........and sometimes I fall asleep waiting for many tabs, windows, and instances of Office 2021 to come back to work (I'm thinking they signed a Union deal, and didn't tell me about it.).

This has been going on and getting progressively worse for about 3-4 months.

Advice? Suggestions? I'd be truly grateful for any ideas you got.

1. some webpages extremely slow loading while others are fine. All load fine on Chrome. Why? Particularly true with https://www.tab.com.au/ that I use 2-3 times a week. In Chrome it's immediate connect.

2. cannot sign in to my members account on (eg) Choice but easy on Chrome. Why?

Love Firefox when it works but I'm getting so frustrated. Seriously considering going back to Chrome - reluctantly.

Also so many website/page freezes & non responses over last ~3 months. Grrrr

This is a problem I only started experiencing yesterday, but if I try to upload an image to a website (such as social media), and I double-click a shortcut for a folder, it attempts to upload the shortcut as the selected file, instead of opening the folder.

This is only a problem with firefox, as I tried doing this in another browser and I was able to open it as a folder normally. Any ideas on what could be causing this or how to fix this?

Hi,

I'm developing a website that needs to authenticate with an external endpoint. Once authenticated, the website receives a session cookie that it uses for subsequent API requests.

I've configured the CORS headers on both Apache and Nginx, but I can't get it to work in Firefox. Interestingly, the same setup works perfectly in Google Chrome.

Here's an example of the headers I receive using a curl call:

curl -X OPTIONS https://crlliria.moval.es/web/session/authenticate \ -H "Origin: https://gis.moval.es" \ -H "Access-Control-Request-Method: POST" -I -k

HTTP/1.1 204 No Content Server: nginx Date: Wed, 04 Dec 2024 10:23:24 GMT Connection: keep-alive Access-Control-Allow-Origin: https://gis.moval.es Access-Control-Allow-Credentials: true Access-Control-Allow-Methods: GET, POST, OPTIONS, PUT, DELETE Access-Control-Allow-Headers: DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range Access-Control-Max-Age: 1728000 Content-Type: text/plain; charset=utf-8 Content-Length: 0

Despite these headers appearing correct, Firefox throws the following error:

"Credential is not supported if the CORS header ‘Access-Control-Allow-Origin’ is ‘*’."

I know the Access-Control-Allow-Origin value is not * (it's set to https://gis.moval.es), so this message might not reflect the real issue. However, I can't figure out how to debug it further.

Questions:

Is there anything specific about Firefox's handling of CORS and credentials that might cause this issue? Are there tools or techniques I can use to diagnose the actual problem? Could there be a subtle discrepancy in the request or response that Firefox is stricter about compared to Chrome? Any help or suggestions would be greatly appreciated!

Thanks in advance.
