Gentlemen, isn't your browser using a lot of RAM? I've been freaking out about it in recent years. That's only with 25 tabs open!! Despite the fact that the system was installed just a day ago, without any tweaks!!!

I am a Cacti developer and we are considering switching from FontAwesome Web Fonts to Tabler Web Fonts. However, on Firefox for Windows only, we are having a major slowdown when using the Tabler SVG based webfonts. The page load is first stalled by Firefox apparently loading all the Web Fonts, which would appear normal with any browser (though exceedingly slow on Firefox for some reason).

However, once the page is loaded, when going off tab to another browser tab, and then back to the Firefox tab that includes the Tabler webfonts, there is a 3 second delay before the tab switches. When we enable the performance analyzer, we find that the delay is almost 100% Reflow of the page, even though the page is static as this point (no changes) from the last time it was activated.

We do not have this issue on Firefox for Linux, MS Edge or any other Chromium browser, only Firefox on Windows. I'm using the latest version 134. Should I be opening a bug?

При заходе на сайте ya.ru и если на нём имеется строка с видео или поиск с алисой, то начинаются сильные фризы. Это ошибка именно в firefox 142, проверенно.

My question is a very obvious one if you look at the two screenshots I've attached. The 'X' to close the Firefox browser keeps disappearing, along with the 'maximize' and 'minimize' options as well. This has been happening for months. The recurrence rate is 50/50 each time I open the FF browser. It's not just an issue with closing or minimizing a page, it also removes the access to my Windows taskbar at the bottom!! Normally, when I move my mouse to the bottom, my taskbar pops up and I can access whatever I need, BUT when the FF browser has NO 'X' at the top corner, my taskbar won't show up at all! This is finally getting on my last nerve!🤦♀

Any knowledge as to why this keeps happening?🤷♀

My FF browser is up to date, as of yesterday. My default search engine is google. My PC is still running Windows 10.....could this be the problem?

I've just opened one simple Web site (in addition to Mozilla), and already CPU usage sits at about 20%! Please refer to my recent posts here at "Why is Firefox Suddenly Taking Over my CPU?" for the problem description. I'm re-posting simply in hopes that I can "send data" on this one from outside my sandbox. Regards -- jclarkw

Hello,

In the DevToolbox, the “Copy all as HAR” and “Create file...” functions are not working. It seems that in both cases, only empty space is placed in the clipboard and in the file (this has been happening since the last update).

Thank you in advance.

After every update, Firefox starts to a blank screen and will not start loading the webpage url put in for over twenty minutes to a half hour. During this time other browsers on my Win 10 PC load immediately so it is not a network issue. It is Firefox. When I see that an update is pending I hesitate to do the update because I know I will lose the use of Firefox until it is ready to respond. It just hangs with "loading X.com" showing at the bottom left of the blank screen. I have been using Firefox for a long time and in the past year or longer it has become very unreliable. There are also instances where without an update it will do this and the only way I can get it to work is to clear the cache and the history through settings. What is going on with Firefox! (And lately there is an update every couple fo days!

When I have multiple tabs open, around the 6th tab, the entire computer freezes. I have to press the physical button to shut down and restart. This behavior started with the last Firefox update. It doesn't happen when I use Brave browser. What changed to cause this?

I'm running Mozilla Firefox for Linux Mint mint 100 - 1.0 version 141.0.3 (64 bit) on Linux Mint 22.1 Cinnamon. These are the latest versions of Mint and of Firefox for Mint.

When I brought Firefox up about a week ago, it presented me with a survey, results of which were sent to Firefox developers. They asked several multiple choice questions about features, but they didn't ask a very important question: Would you use Firefox more if it used less system memory? I currently use Google Chrome for about 2/3 of my web browsing because Firefox uses up too much system memory. I would prefer to use Firefox most of the time, but can't, since it bogs down when memory usage gets too high.

The survey should have included a text input box so users could enter any comments for the developers, and the survey did NOT do that.

So, after completing the survey, I was disappointed that I couldn't comment on the most important issue I have with Firefox. I would like the Firefox dev team to try get Firefox's use of system memory down. A short while ago, I opened 4 websites in Google Chrome, then opened the exact same 4 websites in Firefox. The attached shows the memory usage of each browser.

I get screen tearing on videos or when i scroll on any website. Only happens on Firefox, I've tested Chrome, Edge, Opera.

Smooth Scrolling is Off. Hardware Acceleration is Off. I've tried toggling "gfx.font_rendering.directwrite.force-enabled" Firefox is up to date.

None of this has helped.

I always have multiple tabs open in my browser. Previously, I could easily open (and switch between) 20+ tabs (I have 16GB of RAM). Recently, after opening five tabs, the Task Manager shows 10-11GB of RAM (88-90%) in use! How can this be? I cleared the cache and history, but it didn't help. I installed several RAM cleaners, but none freed up the required amount. None of the five programs worked. Where does that 15GB of RAM go when I open Firefox? When will you finally implement something like Google Chrome—they free up RAM for active pages when inactive ones are opened. Maybe it's because I have so many inactive tabs that the RAM is disappearing? But I had just as many tabs before, some of them inactive, and fewer than 20 active ones, so I could easily open another 20. And now I can't even open five new ones. What's happening to the browser?! SOS!

Dear Support Person,

Yesterday, after being notified that an upgrade was available, I executed the upgrade to version 152.0.

The upgrade completed successfully with my eight tabs populating on the left side along with a new tab showing all the features of the new upgrade.

I opened my Gmail tab and my Yahoo mail tab. Eventually, Firefox froze up, saying it was Not Responding. I looked at Task Manager and saw that Firefox was continuing to grab up memory. I ended the Firefox process in Task Manager.

I then opened it again and deleted all the tabs except for one. It continued to grab up memory.

I then opened it in Troubleshooting mode. It errored out, and I sent the report to Firefox support.

The only thing that has changed is the fact that I ran the upgrade to Firefox. Nothing else has changed.

Firefox has been my go-to browser for years. I am using Chrome as my access to the internet now, and cringe every time I go into it.

I hope and pray that you can bring my Firefox friend back to me.

I am anxiously looking forward to hearing from you.

Take care and God bless!

~ Kyle P.S. I just tried getting information from about:support. I was able to copy the raw data and then the application crashed. I sent the Crash Report to you folks. The raw data I pasted in the Troubleshooting Information box.

Hello For some reason most of the buttons in my toolbar have stopped working. When I first open Firefox they all work, then when I enter websites they stop working. The 'home' button still seems to work, but almost all others (such as the 'back' button etc) can't be selected. This is very frustrating. To note, I am not tech savvy at all.

Thank you in advance for your help.

I normally use Firefox Developer Edition, version 127 because any later version always freezes my whole computer (probably because I'm using a 15-year old PC). Recently all my extensions became disabled. I'm now also unable to install any extension because it says "Installation aborted because the add-on appears to be corrupt". I found some instructions on Mozilla website about deleting compatibility.ini and extensions folder, but it didn't solve the issue. Now I'm stuck and confused as I suspect some of the extension files that should be in my Profile folder may not be there.

The simplest solution in this case would be to use the "Refresh Firefox" option which resets everything to default settings, but every time I do it my computer freezes until rebooted. Uninstalling and reinstalling manually is also not the way to go, because it retains all the settings.

I've tried installing the standard Firefox browser (v. 119) alongside the Developer Edition but the same issue is there as well.

I'm looking for an alternative way to get a clean Firefox install, so I can fix my extensions.

Additional info: - Your system specs? Windows 10 64-bit, 4 GB RAM, Pentium Dual-core, no GPU - Hardware acceleration? Disabled. - Using any mods? Yes, two. Geckium for Firefox, which always works fine. The recent issue started when I played around with Revert8Plus, but it initially worked without issues.

It takes almost a minute for my home page to come on after I click on My Firefox icon. That has only started happening in the last week or so. But . . . also . . . when I sign into my email account with my ID and complete password, even though I check the "stay signed in" box, that does not happen. I need to fully sign in each time, and that, too, time-wise is somehow related to the delay in getting my home page up. On several occasions I have gotten a message that Firefox is not responding. Thanks for any help you can give. I have Windows 11.

Using Google Voice became unusable. Firefox too slow. Had been running just fine up till maybe a month ago when I finally gave in and allowed Firefox to update. Not knowing if it was a Windows or other issue I stupidly did a Windows reset and lost all my installed programs (including Firefox). I did a fresh install of Firefox and manually reentered passwords and bookmarks.

Ran fine for a day or two and is now again unusable. Cleared cache and appears to work OK at the moment but still sluggish.

Hi, After updating to the latest version of Firefox on my laptop, I’ve noticed that the battery drains much faster than before. I haven’t changed any settings, but the browser seems to consume more power even with just a few tabs open.

I’ve already tried:

Restarting my laptop

Disabling unnecessary extensions

Clearing cache

But the issue is still there. Is there any specific setting or workaround to reduce battery usage in the new update?

Thanks in advance!
