Firefox freezes when I try to sign into YouTube via Google. Becomes totally unresponsive and I have to close browser. It's the only site this happens on. I have cleared the cache and cookies, unchecked "Hardware Acceleration" and other recommendations from other posts. Please talk to me like I'm your Baby Boomer dad.

A couple days ago, some weird issues have started:

• All my bookmarks are gone
• Any of the buttons in the UI that open a smaller UI do not work (such as the 3 bar menu)
• Similarly, right clicking to open a menu (such as "Save Image") also does not work
• Any dropdown menus in websites seem to also not work. For example, in this very support page, I could not select an option in the "Which topic best describes your question?".

I can't restart and troubleshoot Firefox since I can't access the 3 bar menu.

The lack of a title bar makes it impossible, for example, to close the application by pressing the "X" icon in the upper right corner. The title bar does not appear when the application starts, but does appear when the application window is minimized and then maximized.

The minimize, maximize, close line at the top of the screen is missing when Firefox opens. If I click the Firefox icon in the task manager to minimize it and click it again to maximize it, then the missing line at the top appears. This has been an ongoing glitch for a week or more. Perhaps you can fix this minor problem?

Firefox occasionally stalls during a page load or refresh. A quit/start sequence of Firefox resolves the stall without further action. Is there a key sequence that invokes a restart: Firefox 140.0.2 (aarch64), MacOS 15.5 (24F74)

Dear Firefox Support Team,

I am writing to report an issue I’ve been experiencing with Firefox on my MacBook Air (M3, 8GB RAM). Recently, Firefox has been becoming unresponsive quite often, and the Activity Monitor shows significantly high memory usage. For context, I typically have two Firefox windows running simultaneously, with approximately 5 tabs open in each window (10 tabs total). This is when I notice the performance degradation and high memory usage.

To help you investigate, I’ve attached:

• A screenshot of the memory usage in Activity Monitor when Firefox is running.
• A screenshot of the extensions currently enabled in Firefox.

I am open to suggestions, such as disabling or removing certain extensions if they might be causing conflicts. However, I wanted to report this issue first to understand if this is a known problem or if there are optimizations planned for Firefox on Apple Silicon Macs.

Let me know if you need additional details, such as Firefox version, macOS version, or specific steps to reproduce the issue. I’d be happy to provide any information that can help resolve this.

Thank you for your time and assistance. I look forward to your response.

Best regards, Hemant

Several weeks ago Firefox worked normally for me. I left for most of the day and when I got home Firefox no longer worked at all. Everything on my home page was gone and when I typed in websites - such as my e-mail program or Facebook, nothing ever came up. I'm not super browser savvy, but I opened the menu and under help was "trouble shooting mode". I didn't know what that was but figured nothing much more could go wrong with Firefox, so I chose that. I had to rebuild the websites I had in a row on the middle of the page. I didn't lose bookmarks, but everything else was different. So I left it that way.

Earlier today, Firefox wanted me to do another update. I thought maybe by agreeing to that, things might return to normal. Noooooooo. It's no better whatever. Now I don't know how to get out of troubleshooting mode to know if anything will work normally again.

I am seriously considering switching browsers, but I have a LOT of stuff bookmarked and that would be very intensive to build all those book marks in another browser.

There is a bug which was reported 3 month ago https://bugzilla.mozilla.org/show_bug.cgi?id=1959157. It appeared out of nowhere and I don't even know if it was fixed since then. But it is bugging me a lot, no pun intended. Any help would be appreciated.

Constantly getting the following messages - "Not Responding." "This application is not responding. The program may respond if you wait. Do you want to end this process?" I am on my email or reading an article on my email and it goes blank. Also, I get "Restore session or start new session." The only way I can get to start my computer ( getting the password box ) is if I do Control Alt Delete many times.

Very Frustrating indeed!

What's wrong with the new release?

Today i decided try the new firefox(140) since it's going to be ESR, but i'm getting hot-fan from a couple of tabs (particularly video streams). Second it's slower and seems to have 4second delay for shutdown..

The laptop is running linux mint with intel i5 (11th), tigerlake (iris xe) gpu. It might not be newest, but it shouldn't have a problem with regular web browsing.

Is it a bug? like it's not maxing my ram or cpu during use.

im using firefox on ubuntu, version 139.0.4. when i browse the internet using firefox, every some time the toolbar and the search bar "freeze" - i am unable to click anything, from the url, to any of the buttons. it takes up to like 1/2 minutes for the search bar and the toolbar to work again. i never had this issue before, neither on ubuntu (and other linux distributions), nor on windows...

Bug Report for Mozilla Team: When you open a Gmail PDF In another window, the zoom setting has a bad response, with much delay, I inform you of this Bug So you can fix it, thank you very much.

Greetings...

I have noticed in my Windows 10 Task Manager that Firefox has an excessive number of processes active when Firefox is started with only one empty tab. By excessive, I found eleven (11) Firefox processes today, and I have yet to even start using Firefox.

I have only a simple Theme enabled and no Extensions enabled in my Firefox. I have tried deselection of the "Use recommended performance settings" but this does not appear to help. Disablement of my Theme increased the number of Firefox processes.

Any idea how I can significantly reduce the number of Firefox processes that appear in my Task Manager when I use Firefox? I really prefer to use Firefox as my go-to web browser, but lately it has become troublesome at times.

Thank you in advance for your help with the above problem. Take care...

I have Firefox running on 3 machines, only one of them is synced to my Firefox account, so that means that I am not running the same addons on all of them. I have Firefox running on Windows 10 and the two other are running on Windows 11. From time to time, I notice that Firefox is running slow and its unable to open normal websites like facebook, instagram, youtube, or any other website that I normally browse, and when I check the Task Manager I can notice one unusual exe running named "crashhelper.exe" which is located in the Firefox installation directory and its signed by Mozilla. Once I kill this task Firefox continues working as nothing happened. This is happening since the last update which was few weeks ago (if I remember correctly). What is this app doing and why it is making Firefox stop opening websites?

Since this week's update of Firefox Developer edition when the browser is restarted tabs do not load until I reset the browser.

I suspect an add-on but have not been able to determine which one.

This is happening on multiple (3) physical computers.

I just started a new work role and haven't been able to find the time to troubleshooting of the issue myself.

This has been very disrupting and stressful.
