whenever i scroll trough a website in firefox, the ewperience is very laggy, feels like its 15fps. i have done basic things like disabling hardware acceleration, smooth smooth scrolling.

Where is the issue tracker for Firefox Nightly on Android? The last few updates have caused the keyboard to block the bottom part of webpages, making it impossible for me to see what I'm typing.

When I have multiple tabs open, around the 6th tab, the entire computer freezes. I have to press the physical button to shut down and restart. This behavior started with the last Firefox update. It doesn't happen when I use Brave browser. What changed to cause this?

I'm running Mozilla Firefox for Linux Mint mint 100 - 1.0 version 141.0.3 (64 bit) on Linux Mint 22.1 Cinnamon. These are the latest versions of Mint and of Firefox for Mint.

Initial performance is good, but over time especially when tabs are opened and closed frequently responsiveness to user input (e.g. tab switching, opening/closing tabs, response to hyperlinks) becomes very slow. After force quitting and restarting, performance is good again for some time. I exclusively use private tabs.

Hi I’ve been a dedicated Firefox user since as long as I can remember across all my devices. Since buying an iPad Pro and setting up with Firefox, as I have on all my devices, on the iPad Firefox performance is really poor. Websites often freeze and downloading pdfs from websites or from SharePoint etc. often does not work. An empty file will be saved. When switching to another browser I don’t experience these problems and I have no other software problems on the iPad. Running Firefox 139.1 on iPadOS 18.5 on a 13” iPad Pro M4 (MVX33HC/A)

Can you please let me know what your proposed fixes are for this? Thank you and kind regards Ewald

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.

Hi, I’ve noticed that Firefox often uses a lot of memory when I have multiple tabs open, even more than Chrome or Edge on the same number of tabs. Sometimes it slows down my system or makes switching between tabs laggy.

Is this normal behavior, or is there a way to reduce Firefox’s RAM usage without losing performance? Are there specific settings, add-ons, or troubleshooting steps I should try?

Thanks in advance!

This started happening a few days ago.

I tried to drag a tab out of the main window to put it in its own window on my other monitor, but the tab just became unselectable, and if i scrolled in the tab bar, the tab icon and text would remain locked in place in the display while the other tabs moved behind it.

The main Firefox window also lost the minimize, restore, and close buttons. The only way to make the tabs work was to close Firefox and relaunch it.

I noticed this happened only after any app in the OS went full screen, be it a steam game, or another Firefox window, or a VLC window, or anything else that I did that made an app full screen in any of my monitors.

I am using Ubuntu 24.04 with KDE Plasma 5.27.12. Kernel is 6.14.0-29. Display server is Wayland.

Initially I thought this could be a problem with the snap version of Firefox, so now I've installed the deb package, but the problem remains. Firefox is the only app which presents a problem of any kind when any window goes full screen.

Here's a video showing what the problem looks like, in case my description was not clear. The ghostly tab in this video is the chess.com home page and you can see it as the third tab from the top right of the video, and it remains in that position as i scroll the other tabs, completely unselectable with the mouse.

Any idea of what could be causing this issue to appear?

Thank you!

Every so often (about 5 times a day?) when I tap the screen, Firefox initiates a page refresh as if I've swiped down from the top of the page. The refresh icon appears fully pulled down, and if I catch it before I release my finger, I can swipe back up to cancel the refresh. It seems to happen on some sites more than others, but I can't find a pattern or reproduce it reliably (maybe it happens more on sites that don't scroll down so the page is always at the top?). I managed to catch a video of it happening, but I don't see a place to upload it.

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 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

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?

I have duck duck go set as my search engine on my galaxy S10+. At some point my Firefox browser updated and now every time I search something, or load any page within the search engine I get a forced web page refresh when trying to scroll down the results page or any page. If I hold my thumb down on the screen and slowly slide it upwards it backs off the refresh gesture and then everything works fine. I have switched search engines, so I know it's not the search page itself, and it only happens in Firefox. I do have 100 tabs backed up but I've tried uninstalling and reinstalling Firefox and starting new but it doesn't matter. Firefox still forces a refresh when I try to scroll down. I've become so frustrated with this that I installed brave browser today to see if that browser did the same thing and it does not, so until I can get some help fixing this I will be switching to brave browser from here on out. Attached is an example after I searched the term "searching the web" it did not have an issue scrolling on the results page, but then I clicked on images and tried to scroll and as you can see it is trying to refresh the page.

Your browser dead ass just doesn't respond when I click on it. I have a new mac mini 4 and have the latest update for firefox. it's absolute dogshit to be honest. I'm lucky if the browser lets me click on anything, eg., bookmarks, add-ons, history are nonfunctional. Also my tabs on the browser get squished together and superimposed such that 2-3 separate tabs appear as though they are one tab. I have never had an issue like this before when using firefox. I don't encounter the issue with safari or chrome, but I don't like those browsers. Do you have insight as to why firefox mozilla is suddently ass?

In the first loading the share menu would only show other firefox devices until a few seconds later other options appear. Closing the menu and reopening would not have this problem so I am unable to check if it's an Android problem

When I want to buy something and my bank want to check payment I change firefox for bank app but firefox automaticaly reload the page. Same problem if I want to sign in somewhere and need pause or copy something from another app. The firefox always teload page and I have to start again. ONLY one help is divided screen. But it is not solution.

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.
