Hello,

I use Firefox as my default browser on my personal laptop. Recently, several websites that I frequent appear blank when I go to the url. I've checked my network connectivity and the websites as well. None are broken. The interesting thing is that I get the same issue when using edge. Anything else I can troubleshoot? Thanks!

This morning Firefox stopped working for every website I attempted to access. The window shows the "Unable to connect" error. I'm currently using Edge for the Mozilla site help pages. I've tried many of the help article procedures, including: 1) Removed and re-added Firefox in the Windows Defender Firewall settings; 2) Scanned PC for Malware (Webroot SecureAnywhere, CE25.1), no threats detected; 3) Cleared recent history from Firefox. 4) Opened Firefox in Troubleshooting Mode but the problem persists. 5) I've also set the Network settings to "no proxy". Windows settings is set to automatically detect settings Firefox was working last night when I was installing an old version of Quicken 2015 (off-line/non-network installation). What's my next step?

About once a minute or more Firefox lag by 10-15 seconds before showing a character or characters I have typed.

It seems to be using a lot RAM. I have one window open with six tabs, including this one, and it is using nearly 8GB. There are 48 processes showing in Activity monitor.

I am using version 135 on a Mac Book Pro running MacOS 15.3 (Sequoia).

It is almost unusable.

Firefox using huge amounts of RAM/crashing

I am on a Mac desktop running Ventura 13.7.3 and running Firefox 135 with extension of Ghostery, Privacy Badger, Google Don't Track Me, Facebook Container, FoxClocks and SoftGreenLeaves theme. All of these extensions have been playing nicely with each other for a long time.

Recently I've been having trouble recently with Firefox doing that thing of suddenly freezing/producing multiple windows and I need to refresh in order to get it working properly again. This has happened three times in the last five days - so frequently that I now keep the refresh instructions on my desktop. Today I heard the CPU grinding and clicked open my Activity Monitor to see four listings of 'FirefoxCP Isolated Web Content' running all of them using in excess of 2Gb. Unfortunately I wasn't able to get a screenshot of the Activity Monitor while this was going on as I had the Mac force quite Firefox and the moment I did, the activity stopped, but I've attached an example of the Activity Monitor showing still high CPU values for a few moments of browsing.

So what's up? How can I stop the CPU grab? How can I stop the frequent crashing?

Excessive pagefile.sys Usage by Firefox

There is a similar (but not identical) topic on Mozilla Connect , and I posted there. But I did not get a response. So I am re-posting on this new topic on Mozilla Support. I have a similar problem to what was discussed on Connect. I am using Firefox 133.0.3 on Windows 10 Professional. After Firefox has been running for a while, I get a message from Windows 10 that the free space on my C:drive is low. I did a directory listing on my C-drive before and after Exiting Firefox; I saw no large files disappearing. Then I decided to do "dir c:\ /ah" to see hidden files. What I saw was that pagefile.sys decreased in size from 29,925,748,736 to 16,270,770,176. This was a decrease of 13.7 Gb. Is this normal? I have lots of windows and tabs open in Firefox. Thanks.

Hello Mozilla Community,

I’m currently using Firefox for my web design projects and facing some performance issues when testing websites built with modern frameworks. As a developer at DE IT SOLUTION where we provide website design and development services, I rely on Firefox for testing due to its robust developer tools.

However, I’ve noticed:

Firefox becomes slow when handling multiple tabs with live previews. Developer Tools sometimes lag during real-time CSS adjustments. I would love advice on:

Best practices for optimizing Firefox for web development. Recommended extensions that won’t slow down the browser. Tweaks for faster rendering of web pages during testing. I’ve explored Mozilla’s tips but would appreciate insights from this expert community. Also, if you’re interested in how UX/UI impacts web performance, you might enjoy this article from my experience: Why UX/UI Design Matters in Web Development (Sharing for learning purposes).

Thank you in advance for your suggestions!

Firefox hangs after starting with "session restore" After I click yes to restore the session firefox just hangs. So I just went right back using Version 138. I reinstalled from scratch still the same problem. At least the older 138 loads my previous session after hanging for 4 hours about and then everything works normally. The newest Firefox does the same, but NEVER resolves, it just keeps on hanging. Doesnt make any sense. What makes the system restore hang this badly. It cannot be old profiles. I completely renmed the old firefox install directory and cleanly installed firefox and it still does this. so it is not inheriting anything. I also allowed it to create a completely new setup in ./mozilla/firefox in the user account.

It also uses more than 117% cpu constantly during this period. See top entry.

Seems like I have to move to Thunderbird/Seamonkey or Brave. Since 2019, Firefox became very "strange"

This mandatory upgrade completely illustrates the point of why so many never did. Upgrades tend to lose functionality- add-ons, etc, that we're accustomed to and still work quite well with don't function anymore with browser upgrades, and there's no viable replacement available so we stick with what works and find other ways to compensate for any perceived vulnerabilities. Now, like Microsoft, you're forcing consumers to do things they never wanted to and taking away the reasons for using this browser to begin with. Given that we've been able to use older versions for years with no issues, there's no sugarcoating that this is all on you, Mozilla. Calling this course of action disappointing is a gross understatement and nothing more than keeping things polite.

Firefox has recently become unreadable--it is blurry, then clear, blurry, then clear. It has become unusable. I've moved on to Edge. After much research, it is apparent that this is a problem unique to Firefox, who hasn't bothered to address or correct this issue. No more Firefox for me:(

Has anyone else noticed that the memory leak issues have gotten way worse since last update?

I work on a potato. Most of the memory is in the windows paging file, on a mechanical hard drive. So freeing up used memory takes longer than it would on a machine with a metric tonne of quad-channel RAM. The past 6 months, Firefox has started having memory leak issues, where it just uses more & more memory until the paging file hits its hard limit and windows kills firefox.

But since last update (135.0 x64), the memory leak issue has worsened significantly.

If I open firefox, and then tab between all current tabs, I get maybe 5 GB of memory usage. So even if all tabs are marked as "active" and loaded into memory, this still isn't enough to cause issues.

But after 30 minutes, that memory usage has ballooned up to >20 GB, at which point windows decides that it needs to free up memory, and kills the process. Which is annoying, because then the browser reverts to the last saved state, meaning many tabs can be lost or reset to several clicks back.

I've tried shaving off extensions, with zero change. I've tried increasing paging file size, but that's just kicking the bucket down the road.

Anyone have a solution to this?
