This morning I could not log into the Schwab customer website using current Firefox version 123.0 on Windows 11. Reverting to version 122.0b9 solved the problem. Before the reversion I tried clearing cache, history, passwords, etc, and I tried a full reinstall of version 123.0. What else would prevent a connection to Schwab when other websites worked fine?

Firefox is broken. For months now anytime I watch a Live stream on Youtube it freezes within seconds and acts like it's buffering. Internet connection is great. Same live streams work perfect on Microsoft Edge, Google Chrome and others. Only Firefox browser is doing this.

I'm trying to use a manual proxy server for Firefox. When entering the proxy address and port number, Firefox outlines the port number field in red and disables the OK button thus refusing to accept my assigned port number. I'm trying to use port number 29842 which was given to me by the proxy provider.

I noticed my laptop was being slow, so I looked at the memory usage. Firefox was using a whopping 5GB of memory on Windows 11. I then looked at about:process and it reported that extensions were using 4GB. I disabled each of my extensions and it still said it was using 4GB of memory. I then uninstalled two of them and re-enabled some extensions and it dropped to 781MB. This is still to much in my opinion, and I want to know how to figure out which extension is being so wasteful. Even a technique on how to figure it out would be appreciated.

Hi everyone,

I'm used to typing one or two letters into the address bar and then the down arrow to access the same handful of websites every day. A few weeks ago, Firefox started randomly moving these around so that the same letters that have always made it open the same URL now opens a different URL and I have to actually search the suggestions. How can this annoying behaviour be fixed?

(a few months ago, the address bar wouldn't delete entries, but this problem vanished as mysteriously as it appeared)

FF version 122.0.1 (64-bit), Windows 10

Hello,

I've encountered a recurring issue with Firefox on Ubuntu where my master password is sporadically not recognized when typed using my external wireless keyboard. This problem does not occur consistently but is particularly frustrating when it does, as it forces me to switch to my laptop's keyboard for input. I'm certain the password is entered correctly; after multiple careful attempts (3-5 times), the issue persists, leading to unnecessary stress and inconvenience.

• • Environment:**

- **Operating System:** Latest version of Ubuntu - **Hardware:** Dell Latitude laptop with a Contour external wireless keyboard, connected through a Dell docking station. This setup is shared with another laptop (HP) via the docking station.

• • Observations:**

- The issue seems to occur sporadically and is not reproducible on demand, adding to the frustration. - It has happened notably on the first login attempt after the computer's first boot of the day. - On one occasion, the problem led me to change my master password under the mistaken belief it had been compromised.

• • Impact:**

This intermittent recognition issue disrupts my workflow and significantly affects my user experience with Firefox. The necessity to switch input methods and the initial misinterpretation of the problem as a security concern are particularly concerning.

I hope this detailed feedback assists in identifying and resolving the issue. Thank you for your attention to this matter Firefox.

Sincerely, Daniel

I have an add-on ad blocker for youtube and have never gotten ads. This afternoon that stopped. I get ads with every video I click and there is no 'skip ad' on the screen. I added another top rated youtube add blocker, quit firefox and then opened it again. Before, if I clicked a video it started an ad and I could go back and then hit the video again, but now that doesn't work, but if I select to show the video in a new tab, there are no ads in that tab. What can I do to make the ads stop like they used to and never appear? Yes and my OS is Ubuntu 22.04

All of a sudden (started today) Firefox will not load ANY websites, except Mozilla/firefox websites. All previous bookmarks, links, and typed in addresses do not load. No changes to virus protection, browser, or any other updates. Other browsers (chrome, opera) work fine.

When I close a private browsing session and open it again, the given permissions for cross-site cookies are still there and Google remembers my last search results from the last private session (in the suggestions below the search box)!?

You may have heard about this, Youtube (and parent Google) have recently declared war on adblockers and non-Chrome browsers. I have reason to believe they have escalated that war to deliberately crash non-Chrome browsers, at least slowing them down to make them non-responsive.

In the past few days, browsing Youtube has caused my system to stop responding requiring a power cycle to clear the problem.

Has anyone else encountered this problem? Is this just a bad setting, or is Youtube acting as malicious as I believe them to be?

I cannot log in to my Gmail account via www.google.pl in the Firefox browser. When I try to log in via www.google.pl, the Bad Request Error 400 message appears. The same problem occurs when I need to confirm login to other websites using a Google account. I simply can't log in anywhere. This problem does not occur in other search engines. A login icon appears on the www.google.com website, but not all related services from Google are available - Google account, Google Play, Gmail, Meet, Chat, Drive, Calendar, and Photos are unavailable - these are just the most important ones that don't work. Cookies are enabled. On December 25, 2023, this problem did not exist. I tried to restore Firefox to an earlier installation date, but it didn't help. I uninstalled the extensions and plug-ins. Unfortunately, the problem remains. Please help me. Regards, Bogaczewicz Bogusława.

In the past two days, any add-on I add to FF browser. does not have a "Pin" option ellipsis activated . Some of my other settings are also botched up: tab used to open on hitting "return" among them.

All comments etc, are either convoluted, unintelligible, and ALL do not address this issue. If someone knows what to do, chime in. many of us have this issue. But please, have a real solution or don't bother us.

I just wrote this blog post and someone suggested I contact you.

I have my default browser set to Firefox on Linux (Debian Bookworm). When I open an http:// or https:// URL, it opens in Firefox, but when I open a file:/// URL, it opens in Chromium. It seems that file:/// URL makes it resort to the MIME type.

Is there anything Firefox can do here or is this a Debian or freedesktop.org issue?

Thanks!

Tim

Hello,

Our website have "cross-origin isolation" setup, more exactly included the following in response header:

Cross-Origin-Embedder-Policy: credentialless Cross-Origin-Opener-Policy: same-origin

but now, the youtube video which is embeded in iframe is not working(blocked)!

How to solve this problem?

After an update yesterday, I found out the password manager integrated in Firefox was completely empty. I tried to rename logins.json.corrupt into logins.json, I tried deactivating all the plugins and I also tried copying the file into a new Firefox profile but it got corrupted right away again. If I put in an old logins.json it works but unfortunately it's a saved file from about 3 years ago.... Any idea about how I could get my passwords back? How to "uncorrupt" the logins.json?

Thank you in advance.

I keep getting a 404 error for a website even after clearing data and cache. I can access the website on other web browsers like chrome and on my cellphone but not firefox

How can I set tabs to automatically preload when I open the browser? I'm just trying to switch from Chrome to Firefox and I can't find such a setting here, although it is a very convenient functionality. I mean that when I open the browser, I can click on any of the tabs and it will be (partially or completely) immediately ready to work without additional loading.

Why can't Firefox copy text to the clipboard anymore? It won't copy text from a web page, from a URL, or even from about:support "Copy text to clipboard"!!! I'm using version 1.22 64 bit on windows 11. I've reinstalled Firefox but it doesn't make a difference. I've tried "Troubleshoot Mode" and it's still broken!!!

I can paste into Firefox but something has broken copy!

I have to create a new question because when I try to reply to the answers I received the system comes up with an error page.

My version of Firefox is 120.0.1 and has been downloaded from the Mozilla website.
