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 know this probably sounds odd but I'm not imagining it. I like many people I live with many tabs open at once. Since the 143 update I come back to my computer the next morning and many of my tabs, specifically my gmail tab and many others will not work. (Oddly I've noticed some random tabs will still work, I have no idea why) I can close the tab and try to reopen gmail in a new tab and it just sits there trying to open but it will not. I've waited 20 minutes. Not until I close firefox and restore my last session will it again work properly. Is there a bug/glitch or is there some setting I need to adjust. I don't want to have to close my firefox everyday. Edge is not having this same issue, so I'm pretty sure it's not a problem with my specific machine. It's like Firefox just decides to quit when I go to bed. I know it sounds crazy.

Hello Firefox Support,

Since the latest update of the Firefox browser, I have been experiencing frequent freezes. The browser becomes unresponsive when performing basic actions such as:

• Clicking on the menu

• Closing tabs

• Copying or editing the URL

When this happens, the only way to recover is to close Firefox and reopen it.

Could you please advise on how to resolve this issue?

Thank you for your support.

Best regards, Mohamed Adel

I just updated my iPhone 13 Pro, running iOS 18.5, to the latest version of Firefox mobile (140.3). The app keeps freezing in such a way that I am unable to press the “open tabs” button to view my tabs. Restarting the phone fixes this issue for a while, but it’s been happening again and again in the last couple of days. This issue is impeding my internet browsing so much that I am considering switching to a different browser for my phone.

My keyboard is often glitching out while I'm in the Firefox browser. This will happen when I'm trying to search on websites or in the search bar.

I've tried a few different keyboards and I've had this problem with Gboard(the one I want to use) and the built-in Samsung keyboard. It seems to work fine for the Microsoft's keyboard but I prefer not to use that one. I've recently updated both of theses apps but the issue persists. The screenshot is what I see when this happens; the area where the keyboard should be is solid black.

If I use the search bar that normally contains the URL, it works but I try to avoid this because using that bar seems to get stuck often on a blank screen(or take a while to load? Not sure what's happening there).

Is there a fix or workaround?

We are getting this Random Error while Scrolling. Before Version 141 it was working fine. Even after getting connected and getting response that update to 141.0.2 but same issue still exist.

Hello Firefox Community,

I'm hoping for some help with a persistent video playback issue on Firefox for Android. I am committed to using Firefox for its privacy and its independent Gecko engine, but this performance bug is a major blocker.

The Problem: When I play videos in Firefox, the playback is very choppy and stutters, appearing as if it's running at a very low frame rate.

Crucial Testing Information:

This issue is specific to certain browsers. I have tested the exact same videos on Chrome, Vivaldi, Brave, and Ulaa, and they all play perfectly smoothly. The stuttering issue happens in Firefox (and also in Opera).

This confirms the problem is with how Firefox is rendering video on my device, not a network or hardware limitation.

Troubleshooting Roadblock:

I have already tried all the basic fixes (clearing cache, reinstalling, etc.).

I attempted to follow standard advice to troubleshoot this by accessing about:config to check the status of hardware video decoding. However, access to about:config is completely disabled in the stable version of Firefox for Android. This prevents any advanced user-side troubleshooting for performance issues like this.

My Device Information:

Phone Model: OnePlus Nord 2T

Android Version: Android 14

Firefox Version: 143.0.4

Given that a critical troubleshooting tool is unavailable, I am reporting this directly. This seems to be a hardware acceleration incompatibility issue with my device.

Any help would be greatly appreciated. Thank you!

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

Ever since this month's Windows 10 update I've been having problems with Firefox. I start it, the menu bar and tab comes up, but then nothing. I can't access any web sites. I tried removing the Windows update, then tried uninstalling and reinstalling Firefox, and then messing with the settings. In each case Firefox would work for a couple of days, then I'd have to start it three or four times to get it to work, then it wouldn't work at all. I've been using it for 10 or more years now (four on this computer) and have never had any problems before. I'm loathe to switch to another browser, but if this can't be fixed I won't have any choice. This is what happens when I start the program.

this site at mlb.com or any site showing a live game eventually freezes up and cannot be closed normally. task manager or re-boot is only way out, starting over with a new instance of firefox after ending all firefoxes.

this has been happening just this past few days, after firefox updated to 143.0 on windows 11 using defender, no other screwed up security software.

firefox needs to fix this, it is not likely anything with the site but rather with firefox latest update, as this has always worked before on this same computer.

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.

Im using Windows 10 Pro 64 bit on a Asus laptop with 32GB RAM in it and a i9-9980HK @ 2.40GHz. It has a GeForce RTX 2060 graphics card in it with 6GB memory. I use it for work and need to have multiple tabs open at a time as a result. I always have at least 4 tabs and can sometimes get up to around 10. I also have Zoom running as well.

I keep seeing a ton of Firefox processes open when I look at Task Manager. Attached is a screenshot I just took with 7 tabs open. It shows 34 processes in the first clump with more open outside of that one.

I unchecked Use recommended performance settings and checked Use hardware acceleration when available but all that did is lower the amount of RAM being used by 100MB. I have 2 extensions enabled in Firefox, AdBlocker for YouTube and AdBlocker Ultimate. They have never been a problem before. This lag and massive overusage of RAM has only started in the last couple of weeks.

Anyone know why this is happening or how to reduce how much RAM Firefox is using? I like this browser and would have to have to switch to another one. Thanks in advance.
