Firefox Community Forum

I open Firefox, my browser, then I type in the site I want to open. It opens fine, however, when I try to open another site I want to open nothing happens except a little dot in front of the requested site keeps going back and forth, but nothing opens. I then have to close the browser, re-open the browser and key in the site I want. WHY? What am I doing wrong. Please keep in mind that I am not a computer savvy person and don't understand much about them. I do know however that Firefox used to work on my computer before update 150 and 151 were downloaded without a hitch. I have tried everything I could think of to fix the problem without success. I am beyond frustrated and need this fixed.

Sometimes, for no apparent reason, on my Win 11 ASUS laptop, Firefox will suddenly use a lot of resources, such that the temperature jumps from about 50 degrees to 95 degrees and the fan runs full speed. It appears the only way to stop it, is to close FF then reopen. What might cause that?

I also have an unanswered previous question about being unable to pay accounts.

Cheers, Keith

Hello there,

I’m experiencing high memory and CPU usage in Firefox, which is affecting my computer’s performance. One issue appears to be that “FirefoxCP Isolated Web Content” continues running even when tabs are inactive, contributing to increased resource usage.

Other browsers, such as Microsoft Edge, reduce memory and energy consumption by putting inactive tabs into sleep mode after a period of inactivity. I would prefer to continue using Firefox as my default browser, but I need a way to manage this level of resource usage.

Could you please advise whether Firefox offers a comparable setting, workaround, or planned improvement to reduce CPU and memory usage from inactive tabs?

Thanks for your help!

I am a home health nurse, and I use Firefox to enter my notes on my visits, but very often, I get a message when I try to save my work to Wait Until Page Finishes Loading and I have to start over, makes me want to switch to another browser.

fonts.googleapis.com is locking up websites for 40 to 60 seconds per keystroke. I have researched this problem and tried everything suggested, but nothing works. Much of the solutions include changing the settings used on menus which no longer exist. accounts.google.com is doing the same thing. This is driving me nuts. Help!!! Latest version of Firefox. Windows 11 desktop computer.

Since updating to 152.0.4 on 30 June firefox has frozen multi times a day, nothing is responsive. I've had to force close and restart. I performed suggest hang fixes, refresh, changes places names, turned off accelerations. None of that resolved the issue. I did not have this issue prior to 152.0.4. No crashes, just hangs forcing restarts - but each one forces me to re-enter all my user information for the various sites I'm using. I've see some references of similar issues with others having upgrading to 152.0.4, but there don't appear to be any clear fixes. Is this issue being evaluated?

While I was using Firefox, the inspector console window started opening and closing all of a sudden. Whenever I try to click on a different tab that is not the one I am currently on, it switches back to my current tab. This issue also occurs on other Firefox-based browsers, and not on any other browser I have installed.

I attempted to change the theme, I went into Safe/Troubleshoot Mode, disabling my extensions, etc, but nothing changed. I've restarted my computer twice already, and yet it doesn't seem to change anything.

The only way I could temporarily halt it was through holding Ctrl, Alt and Shift at the same time, but this only worked for as long as I held all three keys down. What should I do about this?

Ctrl key is shrinking my pages , unable to use any shortcuts due to it. Happened just now after the newest update to 152.1. It happens on every page. Also Login drop-down won't stay open long enough to select anything, it open and immediately closes.

Hi,

I am using macbook pro latest one, and when I use firefox and scroll down from my wireless Mouse to the bottom of the page, the scroll bar jumps to the top while working, is there a fix for this.

Thanks

Hi everyone,

I run a construction estimating construction estimating website where we share project-based cost estimates and detailed breakdown for contractors, architects

I’ve noticed a weird issue in Firefox lately.

Some of the heavier pages (especially ones with large tables, detailed breakdowns, and embedded content) start getting really slow or sometimes even become unresponsive in Firefox. The same pages load completely fine and smooth in Chrome, so I’m trying to understand what Firefox might be struggling with specifically.

I already tried the basic stuff like clearing cache, testing in private mode, and disabling extensions, but the issue still keeps coming back.

It seems more noticeable on pages with a lot of structured data and embedded elements, so I’m wondering if it could be a rendering, memory, or layout issue on Firefox’s side.

Has anyone dealt with similar performance issues on Firefox with data-heavy or content-heavy web pages?

What should I look into next — layout structure, CSS rendering, JS execution, or something Firefox-specific I might be missing?

Any guidance or debugging tips would be really appreciated.

I have been using Firefox forever. It has been running very slow and bugging out especially with you tube on close. I've been working on this for a couple of weeks and am about to give up. My self built system is about 10 months old. Am using a completely debloated MS 11 pro 25h2. Did not ask for AI from Firefox and have disabled AI in Firefox and copilot is long gone. I have tried everything. Am about to quit firefox. Have refreshed firefox and prevented firefox from running in MS win 11 pro "efficiency mode". I usually have to exit firefox with task manager - there are usually 17 instances of firefox running. Mozilla has become Microsoft.

The system: Gigabyte B650 mobo, 32 gig of DDR5 6000, AMD 7700X processor and an Asrock 9060 graphics card with 16 gig DDR6 Vram. All other apps are running just fine. So I don't think a lack of compute is the problem.

Help please! Thanks in advance!

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.
