Firefox prevents going into hibernate mode. It only appears to blank screen until mouse is moved or lid moved. This happened on 3 year old dell and now on new lenovo. I've gotten around it by going into task manager and killing firefox before hibernating. This doesn't happen on a newly opened window. I've noticed that as you use it, in the task manager, (not sure of correct term) the amounts of firefox tasks/threads? increases but does not decrease when tabs are closed. Eventually hibernate stops until I kill the firefox program. I thought this might go away with new lenovo with twice the ram, but happens at same rate. If I forget to kill firefox, I end up with a dead battery. This doesn't happen with edge or other browsers I've tried.

I run a drafting site where we share shop drawings for contractors and architects: https://usadraftsman.com

Whenever I open these drawing preview pages in Firefox, the browser gets slow or sometimes becomes unresponsive. The same pages load completely fine in Chrome, so I’m trying to understand what might be causing this only in Firefox.

Most of the previews are large drawings or viewer embeds, so maybe Firefox is struggling with rendering them. I tried clearing cache and turning off extensions, but the issue still comes back.

If anyone has dealt with similar heavy graphics or rendering issues in Firefox, what should I check or adjust? Any suggestions would be appreciated.

I am using Firefox on my MacOS Tahoe. There is a persistent annoying issue where whenever I close (physically fold) my laptop screen and reopen it, Firefox will be frozen. It will be frozen in the sense that I am unable to interact with any tabs or anything until I manually quit Firefox and reopen it (which automatically reopens all my tabs), making it usable again. This doesn't happen every time I close and reopen my Mac, but it definitely happens the majority of the time and makes the browser hard to use.

I've attached a screenshot of what a new window looks like when Firefox is frozen. It looks just like a Firefox window when unfocused.

Notes:

• It doesn't entirely freeze Firefox. In fact, I can "switch" to a different tab by clicking on the tab and then shutting and reopening my laptop again. The new tab will show on reopening but Firefox will still be frozen. This process can be repeated.
• I can pretty consistently replicate the bug by shutting my laptop, waiting 10 seconds, and reopening it. This will almost always result in the freeze.
• The bug still happens if I'm not focused on the Firefox window but on a different app.
• The bug doesn't seem to happen if I just lock my screen but don't shut it closed.

Things I've tried that haven't fixed it:

• Updating my OS.
• Restarting my laptop.
• Disabling hardware acceleration.
• Disabling themes and extensions.
• Deleting and reinstalling Firefox, including deleting the user data in the "Library/Application Support" folder.

Let me know if there's any more information I can provide or fixes I can try. Also let me know if I should go ahead and file a Firefox bug report for this. Thank you.

I am receiving a not responding message when I try to use Firefox on my Dell Inspiron 3880 with Windows 11

I have tried uninstalling and reinstalling but get the same message.

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.

(My laptop is very slow. I have cleaned the cashe, performed disc cleanup, cleaned the memory, and everything i can think of. I opened task manager and see that multiple instances of Firefox open. (photo #1) I have uninstalled and reinstalled to no avail. I have also tried changing the preferences to 1 instance, but it wont allow me to. (photo #2) Please help.

Hi, I am writing from a fresh Nobara 42 install, using Gnome 48 and the default Wayland session. Firefox version is 144.0.2. I'm not sure this is the proper channel to report a bug, I expected a more standard form. Please redirect me if you know of a better place.

Essentially : click+drag using the tablet doesn't work, be it on web content or on the GUI. When I click+drag to move a tab, the rab is ripped off into a new window as soon as the drag event begins. This happens with both regular & vertical tabs. Simply clicking tabs -without moving the pen enough to trigger a drag event- activates them normally. Click+drag on a bookmark or history item does not work either. When doing so on a bookmark folder, it seems to be always registered as a click, and it consistently triggers the opening/closing of the folder, regardless of the distance traveled by the pointer between the press event and the release event.

Exception : click+drag to select text works fine. However, click+drag to move that text into the address bar to look it up does not work. The text stays selected, the pointer icon doesn't change to indicate that something is being dragged.

Note : I am using the terms "press event", "drag event" and "release event" liberally here. I don't actually know how this all works, it's magic to me. But I felt like this was the most straightforward way of communicating what's happening.

I have a mouse to the side, that I use only for this. But it would be nice to be rid of this necessity. Any help is welcome! Thank you.

When typing to search, address etc keyboard inputs are not being accepted. The typing here is fine but attempting a search or entering a url or even the space bar nothing happens.

Dear Firefox Support,

Since yesterday, I’ve been experiencing an issue where the entire browser randomly freezes for a few seconds. When this happens, everything stops — I can’t open or close tabs or windows, and I can’t type in the address bar. If I’m typing something when it freezes, the input seems to be stored in the background and then appears all at once after about 5 seconds, when the browser becomes responsive again. All add-ons are disabled, the computer has been restarted, and the latest version of Firefox is installed. This issue started just yesterday — before that, everything was working perfectly. No new programs were installed, and all other applications on my system are functioning normally. When I switch to Chrome, there are no issues at all. Thank you for your help.

Best regards, Peter

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

This is happening more frequently. sometimes clicking links works but the cursor will not respond if i hover over the new tab button. To continue I have to select a new firefox window, The unresponsive window remains in error even when a new working window is active.

Hi, I have 30 Firefox processes running and they are taking up ~2700 MB (84%) memory. I have 8GB installed memory. I'm running Win 11. What causes processes to run and how do I know which ones I can end?

Any help is appreciated.

Thanks, John

Hey folks,

I’m not a great user of “forum solutions” simply because due to an accident and head trauma I have developed quite severe concentration issues, or lack of concentration issues however you would like to look at it.

So if you have an idea about my problem give it to me like I’m a 10 year old.

My situation started about three updates ago, and is as follows.

If I open up a new tab or I open up a link into a new tab or window that tab or window will often not scroll. I did eventually discovered that if I click on the “ reload current page” icon up on the toolbar it then scrolls with no issue whatsoever.

I do understand that this is not an end of the world situation, but is happening with greater frequency and it is an irritation which at times really starts to grind that every time I open a new tab I then have to reload that tab in order to get it to operate.

Suggestions welcome.

I use a Lenovo Legion 5 laptop pc and a second Samsung monitor. When the screens go to sleep with Firefox open on the second monitor, the second screen will not wake up again instantly. It can take up to 5 minutes or only after rebooting.

When I close the Firefox window on the second screen from the taskbar on the laptop, the second screen lights up again.

Any ideas?

Thanks!

I've searched other forums and I am not having any luck. If I open 1 Firefox browser then 10-15 open instances will show up under Task Manager. They load automatically. This slows down everything and I have to delete the excess browsers. Would you please offer some advice? Thank you in advance.

Hello,

As the title implies, Firefox has been super annoying to use these past few days after moving a tab. I shift tabs around a lot to keep them organized, yet for the first time ever, shifting a tab has caused a permanent glitch on Firefox.

The preexisting workarounds are to try moving a tab to "unfreeze" the address bar and toolbar, or to move the window to another monitor and letting the issue fix itself, but both options have not done anything.

Additionally, as shown in the image attached, the "moved" tab winds up being a floating tab that is unclickable and floats "above" the other tabs. That tab can be accessed only through the CMND + tab option, which is also another inconvenience.

Really hoping the community has a solve because I transferred from Google Chrome due to Ublock becoming obsolete on that browser, and I would prefer not having to find another browser. Thank you!

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
