Diễn đàn hỗ trợ Firefox

I've gone through the various troubleshooting options over the last month or so and Firefox is still crashing constantly for me, even in Troubleshooting mode. The tabs crash when I'm using a Google Doc, YouTube, Discord, doesn't matter the site; I've submitted about 20 crash reports this morning alone and failed to submit several more:

Any help on this would be greatly appreciated!

Since this week's update of Firefox Developer edition when the browser is restarted tabs do not load until I reset the browser.

I suspect an add-on but have not been able to determine which one.

This is happening on multiple (3) physical computers.

I just started a new work role and haven't been able to find the time to troubleshooting of the issue myself.

This has been very disrupting and stressful.

This morning (08/28/25), I updated my browser to v142.0.1 (64-bit), and Facebook as well as other sites have been affected to the point that I can't even see contents now!!!!!!!

I (God forbid) opened the same sites in Edge, and there's no problem viewing them on Edge.

Is there a way that I can roll back this latest update, because I had no problems until this morning. I'm running a Win 10 Pro OS.

Is there a way to completely opt out of having AI in my browser?

I find recent implementations of AI in Firefox quite frankly disgusting. I don't want to see it, I don't want to use it, I don't want it suggested to me. Not only it's unneeded, but also all your LLMs are a waste of electricity, fresh water and are a threat to my privacy, and we don't even mention all the legal trouble AI scraping creates.

I need a switch to completely remove any mention of LLMs/AIs in my Firefox browser unless I search for it on the internet (and, trust me, I wont; I'd prefer to continue thinking for myself and having real people with skills and talents do things if I can't do them myself) and have none of them touch me in any way. Kill that thing with fire.

Ideally Firefox, one that advertises itself as a secure browser with respect towards its users, shouldn't have any mention of AI in the first place, you know. But since companies are in a craze about it for some unknown reason (trust me, we don't want it; if I want to be lied to, I'd go to a paediatrician to talk about my symptoms, not a language model I can't trust with my data), at least give your users an option to get that awful thing out of their browser it they want to.

Have a nice day. <3

How can you remove the regular reminder to update firefox to the newest version on macos that occurs when you tick "Check for updates but let you choose to install them"?

I can NO longer log into my BANK, I changed the security settings back to "standard" but I STILL CANNOT LOG INTO MY BANK. it's website acts as though I'm a new customer & want's me to open an account,I ALREADY HAVE AN ACCOUNT & HAVE HAD AN ACCOUNT AT THAT BANK FOR MANY YEARS! I have jumped through many "loops" at the bank trying to fix this mess, but they can't,FIREFOX IS NOW THE PROBLEM & someone needs to find out what they changed in their updates that has prevented me from logging into my BANK.

I installed Firefox on a fresh Win 11 install, and most of the the favicons are still generic on the Home Page several days later. Facebook, Ebay and Youtube are the only ones that appear consistently, sometimes other will display, but then be gone again the next time the app is launched. All other links just have the generic letter icons.

I tried deleting the 3 favicon files in the Profiles folder, but it did nothing. I've tried manually re-adding the links, still nothing. I removed the "S" from "https;//" and still nothing. The favicons all show up on my other machines which use Firefox on the same user account, so it is not a problem with the websites themselves.

Not sure if its related, but upon installing Firefox on this machine, it made Firefox on my Mac desktop absolutely freak out. I had to make a significant number of changes over the course of hours to fix everything, so many relating to favicons alone that I don't know what actually fixed it.

What else can I do to try and get these working? Why does Firefox apparently struggle with this particular feature across multiple OSes?

Thanks.

i just want to be able to add drag space to the top of my browser so i can move the window easily while it's maximized. i have been unable to find the customization section of firefox options and there is also no place on this website to speak to an actual member of support staff. this should be simple

I've been backing up my opened tabs for the past 4 or 5 years with the steps in this legendary post: https://support.mozilla.org/en-US/questions/1257866

But this time it failed me and I don't know why. I just switched from Debian to Linux Mint, put everything up to date, but when I copy the sessions-store folder back into my session folder, as described in the post, nothing happens. I tried restoring only the 2 files listed there, and also dropping them in the general user folder, outside sessions-store, but still nothing. I've also noticed that the sessions-store folder isn't created automatically, even if I open a bunch of new tabs now and close the browser.

I don't even know how to begin troubleshooting this to be honest, this is the first time this method's ever failed me :(

I also saw this post: https://support.mozilla.org/en-US/kb/how-restore-browsing-session-backup But it doesn't help either.

My primary google account's language is set to english. If I search normally, then the results are shown in english. If I open a private window and search in google, the results will try to be in the regional english and google asks if I want to switch to english every time.

Hi, just to say, sorry, I’m an absolute idiot, I don’t understand tech at all. I have a VPN, privacy badger and ublock origin. These issues continue whether these three things are turned off or not, so I believe it must be to do with my Firefox settings.

Everything was fine, but now all of the sudden, certain elements of pages will not load.

So for example, today I tried to go to Gizmodo and look at a Star Trek page. Cool. https://gizmodo.com/star-trek-day-announcements-include-a-lego-collaboration-and-a-youtube-kids-series-2000655142

This is not the only site, just an example.

Clicked the comment button to see what people are saying. It won’t load the comments. The comments are completely blocked. They don't exist. When I try to look at the comments, it just shows me another part of the webpage, can't even see the comments.

Thought it was just this site, but then today I was on a plastic surgeon site in Europe to make a payment and it wouldn’t load the payment page.

I tried turning off badger and unblock to make the payment, and it didn’t work.

Honestly I really have no idea what the problem is, I know I’m doing something stupid but I don’t know what it is or how to figure out.

Any help on figuring out what’s going on or where the hiccups for these might be would be welcome.

Thank you!

Ever since upgrading to Windows 11, my Firefox installation has occasionally been unable to resolve domain names of some websites. Example domains:

• apps.powerapps.com
• static.cdninstagram.com
• google.com

As I was trying to debug this, I discovered that the DNS resolution and connection timings are just over 30 seconds (see the attached image). This is highly unusual.

• The issue does not occur with other web browsers on my computer (i.e., Microsoft Edge).
• The issue has persisted across reboots.
• I have already reinstalled Firefox (and wiped the temp files and appdata profile before installing again).
• The issue does not occur with other devices on my home network.
• DNS over HTTPS has been manually disabled.
• Changing DNS resolvers in my Windows settings does not fix the issue.
• The issue is still present with a fresh, unmodified installation of Firefox.

Any help would be greatly appreciated! I love Firefox and do not want to switch to a different browser.

I am on Firefox 142.01 and Windows 11. For the past month or so, after logging into websites such as chewy.com, orbitz.com, marriott.com etc, the screen returns completely blank. I then have to go to Chrome if I want to do anything. I use NoScript 13.0.9 and have allowed all access so not sure what is blocking the browser content. There are no error messages or anything displaying at all. Any assistance is appreciated, thank you!
