Hello! Since the latest update to Firefox (153, I believe) my Firefox has not worked. It starts up perfectly fine, but quickly freezes, becomes non-responsive, and needs to be closed. No matter how many times I attempt to open it, the same thing occurs. There’s been been occasions where it hasn’t frozen immediately so I have been able to turn off hardware acceleration as well as remove my theme and disable all my add-ons/extensions, but this has done nothing. Creating a new profile does not help, nor does trying Safe Mode: the same thing happens no matter what. I tried to reinstall the update, but this also did nothing. I haven’t yet tried to uninstall & reinstall or do a Firefox refresh as those are my last resorts and I won’t do them unless I’m sure they’ll make a difference. I haven’t downloaded any new extensions recently, and this only started happening after the most recent update. I’m not sure what else I can try at this point, and am very frustrated.

Been using Firefox for over a decade. But lately is has become so slow now. Often freezes up if more than two tabs are open or a website is in any way very complex. What settings and issues should I check? What has changed? I can run the same sites on Brave and Edge browsers with no issues or not nearly as slow and bogged down.

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?

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?

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.

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

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.

Dear Support,

Firefox exhibits significant performance and usability issues related to its cookie and data storage management. Despite implementing ad blocker extensions, the browser remains saturated with cookies and persistent advertisements. Regularly clearing browsing data and cookies is necessary; however, navigating to the settings menu is time-consuming. I recommend developing a browser widget that facilitates rapid data clearing directly from the toolbar or frame. Additionally, implementing a session-saving feature to preserve a set of pinned tabs upon closing and reopening the browser would enhance workflow efficiency, allowing for a quick start with a predefined workspace.

This is all happening while using it for simple tasks like search or copying a text.

Furthermore, the browser experiences severe performance degradation when utilizing certain web applications, such as Kapwing for video editing. Since uninstalling Vivaldi, I am considering migrating to an alternative browser due to these issues. Tasks that typically require one minute are now prolonged to hours, as the browser intermittently becomes unresponsive, effectively limiting usability. This sluggishness persists even after system restarts, with CPU utilization reaching approximately 50%, as detailed in the attached performance report. Notably, I encountered a significant delay—up to an hour—to correct a single spelling error or open a new tab, indicative of underlying performance bottlenecks.

Please address these issues to improve browser stability and usability.

Estimator Just tell me how long this is probably gonna take: 4 to 16 hours. Not kidding!

I have tried safe mode. No joy, but it has shown plain vanilla FF is the issue, not extensions.

(I'm using a different browser to make this report, so Share Data button is of no use here.)

For the past month this browser has been really slow. I have cleared cache, deleted all history and its really slow. I'm using starlink for internet. any suggestions

When my system slows down and takes forever to download, I go to task manager and find 15-20 entries for Firefox when I have only 1 or 2 pages open. Why are they continuing to pile up and slow down my machine and how do I stop it from happening?
