I was running TB 128.11.1esr up until 10:00 this morning on Windows 10 Professional 22H2 64-bit. I have some e-mail messages that I cannot delete. This morning I auto-upgraded to 1o 128.12.0esr and then to 140.0esr. I still cannot delete the messages When I try to delete a group of messages (containing the message in question), the messages in the in-box turn from black to gray, and I see at the bottom "Moving messages to Trash". But nothing happens. I did a "Compact folders", and it completed without any error messages. I can look at my Trash folder, and the contents seem to be intact. In one case, I individually deleted all of the messages except one. With this one, I open the message and see nothing in the bottom message content pane. When I do a "cntl-u" to see the RFC 5322 message headers, I see a window that is completely blank. What is happening, and how can I debug this? Thanks.

There were prob 20 or so, but now just blank tabs. My In Box and incoming email still show OK and I can read those in a new tab. but what about the old ones? And if I cannot recover, how can I remove those blank tabs. Deleting the usual way does not work.

On Windows 10. I wonder if Co Pilot has something to do with it

Thanks Tealeaf

I use a MacBook Air running on Sequoia 15.5. Firefox was updated several days ago to 140.0.2 (aarch64).

Since yesterday, Firefox has repeatedly stopped running. (It might have started sooner, but I didn't use the computer over the long weekend.) It won't load pages. Sometimes I get the spinning wheel. Usually, I have to force quit.

I've cleared the cache, restarted the browser, and restarted the computer repeatedly. Restarting the computer sometimes helps. Now is not one of those times.

Also, the About Firefox window is open, and the Checking for updates . . . wheel keeps spinning.

There are no connectivity issues otherwise with my computer or other apps.

Does anyone know why this is happening? Do I need to go back to the last version of Firefox? Uninstall/reinstall?

When navigating through video websites, the browser often becomes unresponsive and refreshes the interface. When accessing other websites, the browser tabs frequently experience crashes.

Details regarding the operating system, laptop model, and browser version are provided below, and the screenshot of unresponsive website has been attached with this, um email or message.

Hi, Once last week I had Firefox crash, like quite literally the window I had open just closed abruptly. Tried doing the refresh using the setup wizard and it did not help. Then I've tried uninstalling/reinstalling several times. Each time it'll open up like new, and within 10 minutes the window closes randomly and then Firefox doesn't launch anymore on my laptop. No error message, just does not launch whether I try to from taskbar or Home or even run as administrator. Seemingly random I've been using Firefox for months and it just started doing this last week.

Sorry for lack of other info, thanks for any help you're able to give.

Когда firefox зависает и windows предлагает его убить, firefox получает права системы и по этому становиться не убиваемым.Система не может его убить потому что у его права системы .В первые заметил этот баг когда сделал браузер firefox браузером по умолчанию.У меня сим роутер при запуске системы открывает браузер тут та браузер и зависает (не всегда ,но часто) в диспетчере задач в этот момент у его права системы.Писал в майрософт ,майкрософт посоветовал пользоваться нормальным браузером и сменить браузер по умолчанию .По совету майкрософт сменил браузер по умолчанию на chrome проблема пропала. Firefox 140.0.2 (64-разрядный) Windows 11 версия 24H2

Every 1 - 2 hours Firefox stops loading pages and I have to shut it down and restart it and restarting takes around 6 clicks on the icon to get it to start.

Also one time today I lost all my pinned tabs and had to manually restore them one at a time.

Using Ubuntu 24.04.2 and latest Firefox. Cleared cache but doesn't help.

What can I do about excessive memory usage by Firefox? I'm about ready to remove from my system. I get memory availability alerts from my very up to date Mac system only when Firefox is active. I've been with you for a LONG time so hate to leave but this is not a good situation.

This is a technical question. Recently, Mozilla added the ability to manually restart the GPU process in about:processes, which is very useful when it leaks memory. Does anyone know if they also programmed Firefox to automatically restart the GPU process if its memory usage becomes suspiciously high, for example, if it exceeds a very high percentage of system RAM at a reasonable baseline (e.g. 7GB out of 8GB RAM)? That would help reduce complaints about GPU process memory leaks. Thanks.

On my Samsung Galaxy s6 when I try to add to the home screen and then choose the option to tap and hold and drag to the screen, it just closes the app it is nothing. It doesn't work. The text options from the pop-up do work but the main graphic where it's trying to get you to drag and drop it does not work.

I left a review and was asked to post this here so here goes. Firefox on android is currently the highest user of power on my Google Pixel 8 android phone. From the battery usage data (since last full charge) Firefox has used: Screen time: 2hrs 33mins Background: 5hrs 46mins Totalling 19% battery usage. Even though I turned OFF allow app to run in background!! Before I turned this off, the battery usage was similar. In comparison: WhatsApp -the next highest- is: Screen time: 1hr 42mins Background: 17hrs 52mins Totalling 14% battery usage. With allow app to run in background ON.

The only thing I can think of causing this is the annoying (in my opinion) way that Firefox does not close down all open tabs when I close the app (by hitting the square control button and hitting clear all open apps button) are they still keeping Firefox running in the background as they refresh?

PLEASE add a setting to close all tabs when closing the app. When I close Firefox on my PC and then open it again, I don't get my old tabs, so it must be possible to do on android.

Firefox has stopped working about 5 times in the last few days while browsing? sometimes on Youtube sometimes it just completely freezes and wont even close with task manager I had to force my pc to reboot yetserday because it wouldnt respond, my pc is rock solid stable while doing anything else including gaming and is 16 months old and have never crashed even once???

Why after the most recent update to version 139.0.4 64bit does any Google search result page on Firefox now use 110% cpu according to about:processes? This isn't the first time a Firefox update has caused this to happen on my computer either. It causes extreme system lag until I'm able to close the Google search result page in Firefox, then everything returns to operating normally. In the past subsequent Firefox updates have resolved the issue but it can sometimes be a while before the next update is released and that one is not always the one that fixes it. Is there something I can do resolve this without having to wait for future updates to be released?

Hi Team,

I’ve successfully built Firefox v135 from source on our internal development RISC-V64 platform running on Ubuntu 22.04 with GNOME 42.9 (Xorg & Wayland), Our RISC-V Development platform does include a GPU HW which support HW Acceleration for GNOME & other 3rd Apps (Supporting X & Wayland), and Work seamlessly without any issues.

The FireFox v135 Application (via ./mach run) starts up normally. But the major issue I'm observing is that Firefox browser is very slow and laggy, especially during search operations and video playback on YouTube I see a poor performance. Upon further check I found that the most of the work is getting done over the CPU and the utilization is quite high, which is causing the FireFox to perform poorly. I also did try to switching to "Use hardware acceleration when available" in the Mozilla FireFox Settings, but still there is no difference with or without this check and Mozilla FireFox browsing Experience is very poor.

Kindly do let me know how we can enhance and improve the overall performance of FireFox Browsing Experience on my RISC-V platform. Any Support and Help is highly appreciative!

Attached a Build Steps and Configuration used for building Mozilla FireFox v135 on my RISC-V64 platform, let us know if there is anything missed. Thank you!

Hello!

I would be very grateful if you could help me figure it out, the browser suddenly stopped working, does not open any tabs, just a blank screen, does not open settings, some buttons simply do not respond at all. I cleaned the SScleaner yesterday, but I did not select anything special there, it was a basic regular cleaning that the program offers.

How do I fix this? reinstalling does not help, the browser still does not work

We receive very large text emails from logwatch on one of our servers. Thunderbird becomes unresponsive for several minutes. When it "comes back" other messages can be selected but no content is displayed, and everything is slow to respond. Clicking the X to close the app takes upwards of 30 seconds to actually close the app.

Is there some setting to increase heap / RAM? Or is this a different issue?
