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?

In support.mozilla.org/questions/1598971 it's still not clear how you're getting this. You seem to be posting this question from a perfectly running Firefox so it apparently starts up and works fine on its own.

It sounds it's related to your Windows desktop shortcuts, or their exact target perhaps — however without knowing their content (destination or commands run) there's not much more to do here.

If you have anything new to add to the questions in the thread above, please post in that original thread so anyone trying to help understands what this pertains to. WELL LIKE I SAID I HAVE HAD THE SAME DESKTOP ITEMS FOREVER EVEN BACK ON WINDOWS 7 AND THIS HAS ONLY HAPPENED ONCE WHEN I FIRST STARTED WITH FIREFOX AND WAS TOLD THEN HOW R TO STOP IT AND BY THE WAY IT IIS NOT A NORMAL STARTING FIREFOX I GET IT WHEN I CLICK ON TH S THDESKTOP ITEM THERE ASWELL HOW COME ALL THIESES YRS HAVE HAD THE SAME DESKTOP ICOND S AND THIS ONLY STARTED ON THE 154.0 AND STILL ON THA 154.1 AND NOT BEFORE AND ITS ME NO I THINK IT IS A FIREFOX ISSUE . i HAVE Y USE THGE SAME DESKTOP AND FIREFOX SESKT OP FOR YRS AND NOTHING AND NOW IT HAPPENS WHY IS IT ME AND NOT FIREFOX//

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?

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.

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

Hi Team,

In Firefox, the close button is only partially clickable and is not accessible on the right side. However, when I hover over it, a square background appears around the button. Could you please take a look?

Thank you

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!

Hello, For about two or three days now, when I launch Firefox and try to open any website, it takes maybe one minute to load the page, then the navigation is OK on every website.

It only happens when I launch Firefox for the first time of my session. If I close it then relaunch it, it's still very swift.

I tried clear cache and remove cookies, just lost my logins lol but didn't work. I also tried with no extensions, nothing changed. Lastly I tried to set "network.captive-portal-service.enabled" to "false" in "about:config" but it didn't change anything neither.

So before I try anything else that could erase something on my profile, I'd rather ask here for some help :)

PS: running FF 153.0.4 on Debian Trixie with Mozilla repos. Only have two extensions: µblockOrigin and NoScript.

Thank you in advance!

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.

About two weeks ago, Firefox started randomly hanging and would stop responding. It wouldn't let me close the program and I always have to restart my system to resolve the problem. Sometimes it only takes a few minutes after restart before it hangs, other times it will be fine for hours.

I've tried multiple solutions I've found online, carefully following instructions: clearing cookies and cache, disabling all extensions, refreshing firefox, creating a new profile, deleting specific files within the Profiles folder, etc.

I've yet to make it more than four hours without the program hanging.

Any assistance or suggestions are greatly appreciated.

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.

Since a month or so, Firefox browser freezes when playing youtube videos. Simply closing the app and restarting won't do the trick, I am forced to open the WIN Task Manager and manually "end task" before I can watch youtube videos again ... until an hour later, or lucky a day later, the same drama unfolds. I run the newest version of each, Firefox and Windows 11. No new extensions or plugins have been added recently. What is to do here? I'm since Netscape on this route and would hate to switch to another browser... :-) Thanks in advance!

This started after the recent update. Any time i open more than 1 firefox window or try to move my window to a different monitor, the Menu Bar pops up and left click will be stuck only making the bar appear/disappear. I just have to close the second window because it becomes immediately unusable. I have the ui setting set to false but it still freezes new windows and doest let me click or type on anything. I've uninstalled and reinstalled, ran troubleshoot mode, got rid of extensions, reset my computer. I'm at a loss. Any help would be great

Firefox MAC freezes intermittently , will get spinning beach ball and status shows Firefox (Not Responding) and must force quit FF.

Sometimes FF after fresh down load from the official FF site for MAC will work great for an hour or half a day and then out of now where go into the spinning beach ball , and unable to enter data into any field - completly bricked and FF status shown as Not Responding. Tnis could happen immediately, or after an hour or anytime within a day or two.

No way of deciphering or determining what in the heck triggers it or why - way way too many factors and settings and variables both within the FF registry and the macOS and the activity I may or may not be doing at any given time.

I will say I experienced this when all apps on my MAC were shutdown, no apps up and running, but I do use Backblaze, Mai Backup X, Malwarebytes, Dropbox, MS NTFS Tuxera, DriveDX which all have ongoing background tasks running all the time or at least in the background from time to time.

However, I have used this setup for the last few years with Firefox MAC with absolutely no hiccup whatsoever.

And then immediately after the last FirForx update on Tahoe, just before I applied the latest 16.5.1 Tahoe upgrade is the intermittant freezing with FF started.

Could this be a FF / Tahoe incompatibility issue?

If not, does anyone out there have anything to fix this?

And yes i did a complete uninstall of all of FF hidden Library folders as well as the "firefox.app" itself - if anyone tells me to uninstall all the hidden FF folders and files in ~/Library one more time, then forget it, I am done using FireFox. Been there and done there a number of times the last week, exhausted with that, and doesn't do a thing.

And yes kept deleting and creating new FF profiles and did not fix the issue.

So does some great genius Mozzilla FF Mac SW engineer have any clue as to the real issue and the real fix without sending me on a wild goose chase?

thank you. clb6

I've just now noticed that whenever I open the website hxxps://www.hex-rays.com it will hang without finishing loading for a couple of seconds, then the entire browser will freeze. I've already tried on a new profile, verified that no addons or plugins are installed there, and no DLLs hooked into the process. This happens on my physical PC and in an (almost unused) VM, with an ancient version 134.0 and the latest 149.0.

Can anyone else replicate this? Should I create a bug report?
