On my Windows 11 IOT Enterprise LTSC system firefox does not entirely close. After I installed my professional tax software from Drake Software LLC the following happens repeatedly: I open Firefox, look at a page, close Firefox, the screen clears and when I try to REOPEN firefox a popup says that it is still running and offers close or cancel. Neither button opens,closes or cancels Firefox. I have to reboot to make Firefox (147.02 64bit) close. This happens every time I open Firefox.

I often keep many tabs open for research, and Firefox memory usage grows significantly over time. Are there practical settings or habits that help manage memory without sacrificing usability?

Hi there, each time I run firefox, a new firefox icon like the attached picture shows up. Now there are several of them. This starts to crowd the dock, also I'm not sure why they are there because I already have a firefox icon in the main dock. Also they are not windows of a firefox window. Clicking on them does nothing.

Every 5-10minints I get white screen for 2 to 30sec when I use the firefox browser. I have tryed the varius advice avelebel , it does not help My computer: Enhedsnavn DESKTOP-KN6DEV0 Processor Intel(R) Xeon(R) CPU E5-1620 v2 @ 3.70GHz 3.70 GHz Installeret RAM 32,0 GB Lager 932 GB HDD ST1000DM010-2EP102, 224 GB SSD INTENSO SSD Grafikkort NVIDIA Quadro K2200 (4 GB) Enheds-id 734915BD-7D9F-484B-B52B-2BD44CFC0F0C Produkt-id 00330-80000-00000-AA837 Systemtype 64-bit operativsystem, x64-baseret processor Pen og touch Denne skærm understøtter ikke input via pen og touchinput Windows

Hi, I’ve been experiencing slow startup times in Firefox, especially when I have my Time calculator web app open. The browser takes longer to load and sometimes becomes unresponsive.

I’ve tried disabling extensions and changing my home page, but the issue persists. Are there any specific settings or troubleshooting steps in Firefox that can help improve performance when using online calculators like this?

Any guidance or tips would be greatly appreciated. Thanks!

When i start fire fox it immediately opens 10 additional versions in the background which I can see in task manager and they take up a lot off memory. If i end task them they immediately come back. This only started recently. I noticed it because now when i open say a youtube video it shows it as number 4. This never happened before unless I had the same video open more than once.

If I can not stop this I will have to uninstall.

When using Firefox on Android on a Xiaomi 15, it frequently freezes when coming back to the app and navigating.

Generally the page will go blank white and the missing bar will appear but not move. If you go to the change app android screen (square button), then the thumbnail shows a transparent region where the page content should be.

Closing the app from there and restarting it usually resolves it, but you will have to re-enter the address or search query.

For the past few years I have encountered a bug on Android (Galaxy s22) that if I am using Google and within Google I open a page, it's fine. But when I click the back arrow it always jumps two pages back, when I click the forward button it is the same (as if Google is not in the short term history), so that I have to search again what I was searching for. This I have reported to the developers with no fix.

I have learned to work around this bug, but past few days the app is more glitchy than ever, so bad that I felt the need to switch to another app. (So far I have not encountered these problems in Nightly.) The app is now switching continuously between pages, between history and browsing in a normal manner is not possible anymore. If I open a website, the app switches to a page I was a few minutes before. After browsing for an hour with many irritations, I almost downloaded Chrome! Luckily I remembered Nightly, which I've used on an android tablet, because the normal app doesn't support a full desktop mode.

Firefox was using GOBS of CPU, so I killed the master process and relaunched, but after launch I couldn't get any pages to finish loading. I then hoped to copy URLs from tabs and paste them into Floorp (which is working fine, as is Chrome), but I couldn't even snag the URLs (dominated by YouTube pages). I ran a full-system virus scan, finding nothing. The most recent Windows-11 update on 2026-Jan-15 isn't recent enough to be a likely causal factor. Firefox has about twice as many extensions as Floorp, but it was running fine until late yesterday (it's now after 3AM). I couldn't get the extensions page to load, so I've attached a screenshot of C:\Users\Mike2\AppData\Roaming\Mozilla\Firefox\Profiles\oa7ou5xk.default-release-1715337056307\extensions There are several other profiles, but there's very little in them (one profile with a times.json & several profiles containing a parent.lock file)

Processor Intel Core i9-9980HK CPU @ 2.40GHz (2.40 GHz) Installed RAM 128 GB System type 64-bit operating system, x64-based processor MSI GT75 Titan 9SG

If I reinstall, will I lose all of my tabs?

When you leave the app, the page often reloads. This does not occur in Chromium-based browsers (such as Chrome or Brave). And compared to Chromium-based browsers, it's slower and uses more memory, making it difficult to use.

My Firefox sometimes freezes in the evenings when using AOL Mail and Facebook. I put this down to my old and slow PC. But I now have a brand new PC working on Windows 11 and all seemed fine, but it happened again this evening. I then logged into Facebook using MS Edge and it was working fine.

I am trying to sing into my Gmail account on my Firefox browser (147.0.1 (aarch64)) -- the entire browser freezes when I go through the steps. I have no extensions enabled right now. This does not happen when I am in incognito mode. I have reset my computer and checked that everything is up to date. It still does not work.

Is there anything I can do to sign into my account?

Hi,

Why are the minimize, maximize and restore buttons not visible?

Sometimes these buttons on the browser window appear, and sometimes all three buttons are not visible. Never had this problem until recent Firefox updates somehow affected this. I cannot tell which update was unaffected since, but this is an ongoing problem and the browser window is blank with no buttons on the top right hand corner. The only solution is to use the file menu and select exit from the list. I may have to open and close Firefox several times until the button icons are visible again. See example screenshots.

P.S. I'm using a 32" monitor if this helps.

Firefox for Android intermittently gets stuck in landscape orientation after the app has been in the background and is resumed. This does not happen every time, but occurs frequently enough to be noticeable during normal daily use. Once stuck, the orientation does not recover automatically. Note:

Happens only after switching to another app and returning later Does not happen on fresh app launch System auto-rotate continues to work in other apps Sensors appear to work correctly

Recovery The only reliable way to recover is: Force closing Firefox from Recents Reopening the app

Device: Samsung Galaxy S25 OS: Android 16 One UI: 8 Firefox version : latest as on playstore Navigation: Gesture navigation Auto-rotate enabled system-wide

Please view screen captures that best show the random issues I have with Firefox browser. This started a few months ago on my desk top PC. I have kept my Firefox up to date using 147.0.1. and still run WIN 10 Home. Although I am sure Linux is in my future!

The issue happens randomly where the top row of my browser disappears off my screen. I can work around the issue no problem but would like to know and understand the issue and if I can resolve it from happening. Firefox is the only app I have this issue with. And it is random and cannot be forced, I have tried....

Thank you for help. John Montani
