i tried firefox, zen and librewolf but every of them has the same problem. smooth scrolling is sometimes good but sometimes so slow and laggy, especially in a tab that has a video. in tabs that has a video always have that issue and tabs that not has a video does it sometimes. its like scrolling is in 60hz when it happens. i tried uninstalling lots of times but didnt fix.

Gentlemen, isn't your browser using a lot of RAM? I've been freaking out about it in recent years. That's only with 25 tabs open!! Despite the fact that the system was installed just a day ago, without any tweaks!!!

I had a bunch of tabs open (apparently in Window 2). One of the tabs had some page I wanted to close. I hit the x and all the tabs disappeared. I went to view recent browsing and the tabs are there in Window2. But when I click on window 2, they don't go back up to the top. If i click on the up arrow they go away, but come back when i click same (now down) arrow again. I want them back up on the top to use. WHERE do new windows come from. EXPLAIN this to me.

Good day. For the last week or so, I've not been able to access my banking website login page. I've tried in Chrome, it works, but I prefer not to use that browser. I can get to the primary website, but when I choose the log in page, I just get a blank page. I've not had this issue before and I've been using Firefox and the same bank for years. Do you have any suggestions as to how I fix this?

With the profile system, which I just used to try and fix another problem. Deleting them doesn't work I've tried manually deleting the profiles as well but they still show up in the UI and it just recreates the folder again if you try to delete it or open it. If you use the UI to try and delete it the instance and page it opens is simply blank. And now the profile I'm trying to delete isn't open. I'm trying to delete it from "original profile" and when I do it opens the a new instance of firefox with the profile I'm trying to delete with in the address bar: about:deleteprofile but the screen is empty.

Hello,

I have been testing all browsers I use (Firefox, Chrome, Edge) on Cloudflare Post-Quantum Key Agreement to verify PQC support. They all support the X25519MLKEM768 hybrid scheme (i.e. Cloudflare web page returns "You are using X25519MLKEM768 which is post-quantum secure").

The issue: When I run the test in Firefox multiple times by doing repeated hard refreshes (Ctrl+Shift+R), quite often the result is "You are using X25519 which is not post-quantum secure". Sometimes the very first run after opening Firefox gives the X25519 (failing) result. "Often" varies. Sometimes it's around 10 fails out of 50 tests, other times it's 1 out of 50. It seems random.

I have read that sometimes networking equipment or even ISPs can be the cause of PQC requests falling back to non-PQC due to the long keys in PQC, but I do not see this intermittent issue with Chrome or Edge on the same computer/network/ISP as Firefox. I have not seen a single failure so far on those two browsers. The only variable I am aware of is the web browser.

I also tried connecting to a cellular hotspot as well as disabling my Norton 360 firewall and the results are the same as above.

Looking for help to resolve this issue. Thanks.

I want to keep the original profile but the process is confusing to me. Can you tell me a simple way to keep the original profile or else set the original for me.

Thanks

Hello,

Since a recent update, I can no longer drag and drop files from the Firefox downloads panel directly into Outlook Web (webmail) as an email attachment. This used to work fine before.

Steps to reproduce: 1. Download a file (e.g. a PDF) 2. Open the downloads panel (the arrow icon in the toolbar) 3. Try to drag the file from the panel into the attachment area of a new email in Outlook Web 4. The file does not get attached — nothing happens

Expected behavior: the file should be attached to the email, as it was before.

Workaround: I have to open the downloads folder via the folder icon in the panel, then drag from Windows Explorer instead.

Firefox version: 150.0.2 (64-bit) OS: Windows Webmail: Outlook Web (outlook.office.com or outlook.com)

This is a regression, it worked in previous versions. Is there a fix planned?

Thank you.

Отправил новую версию своего расширения (Keycure) на проверку 28.04.2026, прошло уже 9 дней. При этом ранее в поддержке заявляли, что проверка длиться не более 5 дней. Просьба разъяснить ситуацию.

С уважением, разработчик Real1k.

Hello,

On the Firefox home page, there are shortcuts. I have pinned some of these shortcuts. When I click on a shortcut, it opens in the current tab. I would like to have the shortcut I click, open in a new tab, without having to Ctrl+click Is this possible?

Subject: Feedback: Please Show Full URLs by Default and Disable “Show Search Terms in Address Bar” by Default

Hello Mozilla Firefox Team,

I would like to suggest two changes to Firefox’s default address bar behavior that would improve transparency, usability, and user trust.

1. Show Full URL Addresses by Default

  Currently, Firefox hides parts of the URL such as “https://” and sometimes simplifies the displayed address. I believe Firefox should display the complete URL at all times by default, including:

• Protocol (`https://`)
• Full subdomains (`www`, `m`, etc.)
• Complete path when relevant

Displaying the full address helps users:

• Better verify website authenticity
• Detect phishing or deceptive domains more easily
• Understand exactly where they are navigating
• Maintain consistency with technical and professional workflows

2. Disable “Show Search Terms in the Address Bar on Results Pages” by Default

  The feature that replaces the actual search engine URL with the search query text can be confusing and reduces transparency. Many users expect the address bar to show the real URL of the page they are visiting.

I recommend disabling this feature by default because:

• It hides useful navigational information
• It makes copying/searching URLs less predictable
• It can create ambiguity about the actual site/page being viewed
• Advanced and privacy-conscious users generally prefer seeing the real URL

Users who prefer the simplified search-term display could still enable it manually in settings.

Firefox has traditionally been a browser focused on user control, openness, and transparency. These changes would align well with those principles.

Thank you for your work on Firefox and for considering this feedback.

Hey there since a week when I brows with Firefox on Windows desktop the RAM uses jumped from around 60% spiked to 92-95% RAM and that changed just come a long a week ago. If change brows like Chrome different story, back down at 65. So you can also see a massive number on Firefox system running.

Question: Whats the reason for the change? What happend?

Best, Janosch

I need to stop google from automatically searching in the address bar so I can use about.config.

No help has worked from the web. Commands suggested by users don't exist or they use circular logic. In other words I can't go to about.config and make changes because I can't get to about.config because google searches it. I have turned off everything and nothing gets rid of the google search. I can go to other searches but that doesn't help.

I'm using a HTML file as a hypertext that catalogues a hard drive or folder. I want the file names to be clickable--to open the file, but but the file:/// href is blocked. What is the work around. All of this is local

Firefox FREQUENTLY totally removes added applications attached and it totally screw up my ability to access anything when you remove my Bitdefender application from access then I have to again EXPLORE added applicaitons!!

Does Mozilla ever sell VPN information to ANY 3rd party for any reason?

I offer cyber security to small business and I would like share your Free VPN opportunity with them. believe it or not, other free VPN actually SELL their information in the terms and agreement to 3rd parties. I want to know of Mozilla does or does not do this.

Thanks!
