When I wake up Firefox from sleep overnight, it is unresponsive until I force quit. I am on v147.0.4 on my M4 Mac Mini. It doesn't happen in shorter sleep periods. I can click something in it and then when I switch to another app, it responds. But the browser on normal interactions won't respond at all.

Roblox was blocked on my device and I wanted to get it unblocked and play it on Infrexa with Firefox. I already followed steps mentioned on the official webpage: https://www.infrexa.com/now-gg-roblox-login-and-play-roblox-unblocked-on-your-browser so please don't advise similar troubleshooting methods.

Now I am able to play roblox but the problem is that when I play the Roblox through "Mozilla Firefox" it shows an error "Firefox is already running but is not responding" and then becomes unresponsive when pressing refresh button, the fan gets faster and device heats up with too much hanging. But when I open the Roblox through "Chrome" it comparatively works good and asks for login details and after redirection it allows me to play Roblox Unblocked without any issue. "Roblox unblocked" here simply means a technical sense, meaning “not crashing” or “free from software or network errors and or browser malfunction".

I have been using Firefox for a long time and my passwords and user ids are saved in the browser so I want to continue using "Firefox" as default browser but I am having the issue in playing roblox unblocked and other games through Firefox browser. I think the current issue that I have started facing is especially after a recent windows update.

I also tried many other gaming platforms like Official Roblox.com, Now.gg Roblox, easyfun.gg and web.cloudmoonapp.com but all of them faced same issues on Firefox while running ok on Chrome.

I am currently running Windows 11 (25H2 Licensed version). I want to play roblox unblocked on my device using Firefox (updated). My parents have already allowed me to play Roblox and I am playing it on my own device and internet connection. Please fix the browser issue and unblock Roblox for me. Please also check my browser version against Windows 11 compatibility if possible.

If you fix this issue for me, I will be grateful to you.

Starting about a week or two ago, I noticed the text of Firefox is grainy. But when the cursor moved, it would get grainy in a different way. So, some letters which were previously unreadable became readable, but other letters became unreadable.

Going to the same web pages with other browsers renders the page readable. So, the problem seems to be Firefox specific.

Even while typing this, portions of the characters on my screen blink in and out.

If there is no solution, I will have to utilize some other browser.

Thank you,

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....

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.

Firefox continues to freeze up even after many FF updates. I am running Ubuntu 22.04LTS. Firefox freezes for no apparent reason. I am lucky if I can just close the browser. But often times I must do a hard shutdown of my laptop. Since the problem first appeared about six (?) months ago there have been a number of Firefox updates, but this problem continues. When will it be fixed finally?

How to completely turn off firefox "mouse enhancements".

1. There used to be a choice in settings for Firefix mouse control to be optional. It is no longer available and apparently FF has created default mouse behavior.

The mouse behavior has become errant in a variety of ways. It interferes with everything online and started doing the same on the desktop.

The wheel is configured for three lines at a time on desktop. I do not want the mouse wheel to be doing anything else. I want either or both mouse buttons to open menus and function normally with links, copy and paste.

When looking in about:config the extensive number of configured mouse defaults is shocking. it is impossible to determine how to disable or delete any of them.

It has become impossible to scroll with the wheel and the scrollbar because the mouse jumps all over the page as if possessed.

It is impossible to scroll 3 lines at a time with the wheel, instead the mouse goes up and down and jumps to the top. Changing the number of scrolling lines on Desktop and in about: config so they are both 3 did not solve the problem. Tried changing both to 5 . . . no joy.

Expandable menus no longer open on some websites.

It has also become impossible to us the scrollbar effectively, instead the same behavior manifests as it does with the wheel - the mouse is jerky, going up and down and jumping to the top of the page, unpredictably.

Either way the mouse gets stuck moving up and down. After having successfully scrolled past where it was previously it returns, repeatedly, to the same previous lines each time I try to scroll further - in an endless loop.

If the mouse does functional, briefly, then half way down the page it starts misbehaving again. I already replaced the mouse several months back when the problem started, however, it was not constant. Then it started again with the new (usb) mouse. (Yes, I've cleaned it. No it is not worn out yet.)

2. Via a search I did find a list of adjustments to make in about:config while learning unexpected mouse behavior had become a common problem. I made at least 20 adjustments, and amazingly, there was no longer a problem! Smooth scrolling, no problems. However, after using the browser, closing and opening it numerous times, the errant behavior returned.

3. If there is no way to completely turn off FF mouse control, or use about:config to disable it entirely, then what is the last FF version that allowed saying "no" to what used to be optional mouse control, so it is possible to change back to it? If there is no other way to solve the problem, that should do it.

Any suggestions or solutions appreciated.
