It takes almost a minute for my home page to come on after I click on My Firefox icon. That has only started happening in the last week or so. But . . . also . . . when I sign into my email account with my ID and complete password, even though I check the "stay signed in" box, that does not happen. I need to fully sign in each time, and that, too, time-wise is somehow related to the delay in getting my home page up. On several occasions I have gotten a message that Firefox is not responding. Thanks for any help you can give. I have Windows 11.

Hello, I used to use FireFox consistently. Then I noticed a downgrade in performance. I checked Task Master and saw this FireFox with 45 entries. With few CPU entries, but over 3 Gigabytes of Memory usage. Why would that be, and what can I do to correct it and still be able to use FireFox?

This started after the recent update. Any time i open more than 1 firefox window or try to move my window to a different monitor, the Menu Bar pops up and left click will be stuck only making the bar appear/disappear. I just have to close the second window because it becomes immediately unusable. I have the ui setting set to false but it still freezes new windows and doest let me click or type on anything. I've uninstalled and reinstalled, ran troubleshoot mode, got rid of extensions, reset my computer. I'm at a loss. Any help would be great

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.

Every couple of minutes Firefox just freezes. YouTube buffers, all open tabs just stop working. I can open new tabs but i cannot search up anything or go into any websites. Is there any fix for this?

Since a month or so, Firefox browser freezes when playing youtube videos. Simply closing the app and restarting won't do the trick, I am forced to open the WIN Task Manager and manually "end task" before I can watch youtube videos again ... until an hour later, or lucky a day later, the same drama unfolds. I run the newest version of each, Firefox and Windows 11. No new extensions or plugins have been added recently. What is to do here? I'm since Netscape on this route and would hate to switch to another browser... :-) Thanks in advance!

My Firefox desktop app recently updated. After it updated, I now cannot access anything by right clicking. When I right click, a giant window of options shows up (see image). It doesn't change no matter what I click on. When I try to select something in the giant window of options, nothing happens. I'm having a very hard time with it, particularly because I can't open links into new tabs now.

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?

I've been using Fire Fox for decades, but lately it is so slow, I thought there was something wrong with my Windows 7 ultimate. I've done full Windows reboot, to no avail. Then I see the internet t hat FireFox is starting to implement AI. I thought that may be the issue, but after looking into it, looks like that isn't an option with my old Win 7 OS. So if that isn't the problem, how can I find out what is bogging Fire Fox down? I keep a watch on my CPU usage, and the usage is going nearly to 100%, when it used to barely go over 10%. When I check the actual CPU usage, it shows as many as 15 or more items tied to Fire Fox.

Is this all a result of continued use of Win 7? I'm planning to move to Linux, but that will take me some serious time and effort. Gerald

Windows 11. I have my taskbar behaviour set to ‘Automatically hide the Taskbar’ So usually the Taskbar is not displayed, but when I move my cursor to the bottom of the screen it reappears. With Firefox I cannot make the Taskbar reappear.

I've been having an issue of, whenever I tab into Firefox from a different application on my computer, the alt menu opens. Firefox seems to be interpreting me opening the program as pressing the alt key, because even when I have the menu bar set to always be open, the input immediately goes to the "File" dropdown option of the menu, just as it would if I pressed the alt key. However, I tried to troubleshoot this by 1. opening a program that tracks keyboard inputs and that didn't show such a thing happening, and 2. I checked if this issue was happening with other applications that have switch the input to the upper menu bar when the alt key is pressed, and that was not the case. This is making it a lot harder to use Firefox, as using a keyboard shortcut to open a new window (ctrl+shift+p, or ctrl+i) while in a normal Firefox tab, it will not automatically open to the new window (as it is set to do automatically), it will also not let me open the new window -- either by alt-tabbing or by clicking the new window on the windows taskbar -- and instead reopens the alt menu and sets the input to that menu, locking me to the original Firefox page unless I tab into a completely different application and then into the new window. This issue also makes me unable to input key commands or text into my active tab immediately when I reopen it, instead forcing me to close the alt menu first either or clicking somewhere on the page. And since I don't keep the alt menu visible at all times, this forces the screen to shift up and down jarringly when I'm simply trying to use the computer.

I'm using Firefox on a Windows 11 computer. I've tried refreshing Firefox and have tried my absolute best to find articles related to this issue but to no luck. Thanks for any help or advice!

While running Firefox on MacBookAir with macOS 15.7.2 to browse simple websites I keep getting the below warning message. I may have 2 or 3 other apps open (like Apple Mail, MS-Word, Preview). "Heavy memory usage You're running out of memory and your Mac may become noticeably slower. Consider quitting some applications. Firefox 2,48 GB" So I quit Firefox to re-open again and continue my work. Does somebody has an hint where this message can come from ? Any settings to change on my MAC ? Thanks for helping

Is there a way to have Firefox start with all, or all but the first tab unloaded?

My Firefox starts with about 100 tabs open and many of these now have ads running which makes Firefox very slow. It seems to take ages and ages for all the tabs to load.

Maybe if all the tabs were unloaded when I start Firefox it would be quicker to get up and running??

I'm running Windows 11 on a desktop with an i5 CPU and 32 GB of RAM.

Any help much appreciated.

Every since I updated my MacBook Pro M1 Max chip to Firefox 142.0.1 (aarch64), Firefox locks up & has to be "Force Quit" & restarted almost every day. Please update the app ASAP so I don't have to convert to Google Chrome. Thank you!

Hi, After updating to the latest version of Firefox on my laptop, I’ve noticed that the battery drains much faster than before. I haven’t changed any settings, but the browser seems to consume more power even with just a few tabs open.

I’ve already tried:

Restarting my laptop

Disabling unnecessary extensions

Clearing cache

But the issue is still there. Is there any specific setting or workaround to reduce battery usage in the new update?

Thanks in advance!

I have been dealing with an issue in Firefox on Windows 11 for several weeks now hoping for a fix soon but it has not come yet. When I am browsing on eBay, it will lock up and I have to identify the thread in Task Manger and kill it (just the runaway thread, not the entire program). I can then continue of eBay for a short time before it happens again. This only happens on eBay while just browsing, not bidding/buying. Is anyone else having this issue?

Ever since I got 133.03 my Dell cpu freezes a lot. Over the last hour it froze 15 times. This is terrible reliability.

I hired Dell Tech Support and they checked my software and there were no issues. I have run advance Norton features and there are no problems. Therefore the issue is NOT with my 20 month Dell computer.

Firefox has always been reliable until late August. For four weeks it would freeze and lock up. by the end of Sept it was slightly better and then fine in November. Now it only freezes, put the mouse over the image and it freezes. Play with it for a while and it unlocks.

I am totally fed up with Firefox. I'll be starting my taxes soon and year end things and can't afford to have all these issues and rebooting to help eliminate the issue.

When is Firefox tech support going to help me? When is Firefox going to fix the issue? After Christmas I am looking into the Microsoft software......enough is enought!
