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.

i have said many times that i keep getting Firefox running but not responding . i have contacted many places and complained had some of your r tech try and help now with the new update i am still getting it yet i was told it would be fixed. i have reinstalled i have removed and shut off some add ons cleared cache all but cookies and still i get it funny until the last 2 new versions i never had this problem it is a Firefox problem not mine. i would have thought you would have fixed it by now

i have tried anew profile got a the newest version and it still does not help i guess the people doing the updates have no idea how to fix the issue or care none of you can really help all the idea you have had i have tried and still i get the same Firerfox running but not responding' guess you will force me to go to chrome instead which does not do this nor does Edge so you can not tell me it is not a firebox issue because neither Chrome or hedge with by the way all the same desktop icons i have had for years work

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!!!

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//

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?

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.

So I know these websites are kind of crap anyway, but I have issues with scrolling bsky.social (and other clients for it like witchsky) and twitter. The further into the timeline I get, the more frequently these webpages lag.

They begin freezing every few seconds for a few seconds, during which they queue left or right clicks, page up/page down, and various other commands, only processing them once it unfreezes. Firefox itself still works during this freeze, e.g. opening the main menu. Also, I can still scroll up or down to a limited degree, though this just exposes empty, unrendered webpage until it unfreezes.

bsky.social has had this problem for a long time, but twitter only recently developed this issue after I had to do a cache clear, cookie clear, etc. trying to log in a few weeks ago. Prior to that it didn't have this issue.

Task manager hasn't really helped elucidate what's wrong, so it might be an about:config that I set or even an unruly extension, but I really don't know what to try.

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

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!

This has been in the last month or so. It will freeze up and I can't break out of it. Last time it froze the whole computer and I had to power down and restart. There must be something that changed. And there must be some way for me to be able to quit when this happens. Last time it was on a video call with my 104 year old mother and it is very annoying. The whole thing froze and I had to restart the computer and when I got it back up, she was off. I need some way to break out so I don't have to do a complete restart. t.

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.

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!
