Firefox Support Forum

Yesterday Firefox started closing at random, sometimes instantly as soon as I open it. The crash dialog doesn't open, and if I go to about:crashes my most recent unreported crash is from 2019. Tried refreshing, reinstalling, completely wiping all profiles and starting fresh. If I use troubleshooting mode it won't open properly at all. I am at a bit of a loss, any ideas?

Hyatt.com links to websites work on every other browser (Chrome, Brave, Opera, Edge) but hotel websites on Firefox just spin endlessly and use too many resources. They never finish loading. I've turned off ad blockers, DuckDuckGo, and a few other add-ons to see if they're the issue, adjusted multiple other settings (proxy, etc.) and it makes no difference. This is becoming an issue with multiple websites in Firefox in recent weeks.

Fix your browser.

Firefox uses too much memory, sometimes 20GB on a 32GB Windows machine. It's usually one or two threads which are hogging incredible amounts of memory. This time I had about 30 tabs open.

Today I tried Firefox about:memory "Minimize Memory Usage" several times, and it was largely ineffective.

I did a "create memory dump file" of one 5+GB bloated thread using task manager, but can't find a way to upload the compressed archive with this report for analysis. Finding a way to report this issue was quite a challenge. It seems most help avenues are now missing/moved, and other reports of this type of issue are "Archived".

I tried killing the 2 bloated Firefox threads and checked for tabs which might be missing or malfunctioning. Everything continued to run normally while more than 10GB of memory was returned to system use. Leaving these bloated threads overnight doesn't improve anything, in fact I can often get up and find my machine is completely out of memory because Firefox consumed it all. My smallest machines have 16GB RAM.

These memory issues aren't new. I've been reporting them off and on for more than a decade. They get better for a few months after reporting, then they get bad again in a few more months. The battle to get memory leaks fixed is continuous while Firefox springs more leaks.

I'd like to give you the memory image I generated so you'll at least have some real data to look at and analyze for this report.

The attached task manager snapshot image is a very minor example of this issue. The numbers keep increasing like there are one or more large memory leaks.

fedex.com has broken my browser!

I have a FedEx account for my business, but I no longer use it. However, I also receive packages from FedEx from time to time. For reasons that cannot be explained by anyone at FedEx, my Firefox browser will not allow me to create a new FedEx account to manage my deliveries. In other words, after I enter my new username & password, the FedEx website comes back with a failure message with words to the effect that, "This didn't work, please refresh your page."

I called FedEx tech support & learned they are now totally incompetent. The only solution that was offered was "Clear all of your browser history". I didn't fall for that - I did however delete all history with "fedex" in the link. I also removed all 31 cookies associated with fedex.com. Then, I re-started the browser, and tried again:

Upon summoning the fedex.com login page, the login information was pre-filled with the userid & password for my old, unused business account! How does this happen without cookies or history? Where is fedex.com getting this data? Is it stored on my browser - or does fedex.com have some nefarious scheme whereby they're using my computer id or IP or???

I need to delete every shred of data in my browser that is associated with FedEx - how do I do this?

I have the latest FF. And this is my system configuration:

Processor : Intel(R) Core(TM) i3-4170T CPU @ 3.20GHz 3.20 GHz Installed RAM : 4.00 GB System type : 64-bit operating system, x64-based processor

Lately I've observed that my FF is eating up lot of my system resources (see Image) and is slowing things down. In Task Manager I've observed it's running several Processes. Is that normal? It's actually more than 31, as many Processes not shown in the image exist down in the list . Sometimes it shows 43.

So what's wrong? Any solutions?

So I know this has been talked about, but none of the "Solutions" work. I'm not sure why or whats causing it, but my YouTube never loads fast, or hardly at all. Usually the video only loads/buffers till about 1 min into any given video. Mind you this is only on 720p or 1080p HD. I never go any higher and my internet speed is ~400Mbps down and ~22Mbps up. I've already tried the following:

1. Disable Hardware Acceleration 2. Clear Cache and Cookies 3. Refresh Firefox 4. Check HTML 5 Video Player 5. Made sure Firefox was updated

I do use some extensions like: - Dark Reader - Privacy Badger - uBlock Origin - Bitwarden (Shouldn't affect) - Honey (Isn't turned on for YouTube) - Enhancer for YouTube (New, so it does not affect load)

Any Suggestions?

So I was doing some simple online school work and my browser keeps crashing. Its been doing it for a few days now. I click on a link that sends me to firefox? Crash. Click on another tab? Crash. I watch a video. Crash. It also glitches sometimes where I click back on one of the tabs and there are some black squares on a webpage. I have a feeling it has something to do with me trying to fix the usable RAM issue, but idk. Is there a solution that will help solve this issue?

Prior to a few days ago I could type "Ama" into the address bar and then press Tab to start search Amazon. However, it now goes to a recent history item instead (see image). How do I fix this?

Until recently my browser accessed all the sites I have used for years and now I cannot access them. As an example the message I receive is "You don't have permission to access "http://booking.jetstar.com/au/en/booking/select-flights" on this server".

Reference #18.62052017.1660274157.1f6107dd Other sites like my banking site I can access freely on Edge but cannot on Firefox. No error message in that case, just says error try again. All this started after I loaded Norton. I have had them look at the system, and they have, but also point out that it is not them as I can access the site from Edge. I have looked at the help page and their are thousands of people with the same query but no fixes! As a long term supporter of Firefox I am disappointed that I now have to use Edge to do most of my business. HELP

I was on phone for a couple hours last night with my satellite provider HughesNet to figure out why nothing would stream. We never gt it figured out. Then, I tried another browser and it worked fine!

Ihave been becoming more and more disenchanted with Firefox this year. SOOOOOOO many problems, it makes my life harder. The only alternative is Google. Everything works with Google pretty much. BUT I HATE GOOGLE!! EVIL. So please fix firefox!

ever since the most recent update last night, these horrid blue boxes have appeared around every intractable element once clicked on (except on complex js based websites like twitter and youtube), no amount of farting around in about:config nor even using troubleshooting mode has gotten rid of them. caret browsing is off. windows' narrator is off. ive also tried disabling all of my plugins, which had no effect

it appears to be the exact same issue that this user was having. i tried all the solutions in that thread. no dice. i have also tried all the solutions in this reddit thread

ive attached a collage of some examples below.

ive tested these same sites in opera gx to compare, it does not exhibit this faulty behaviour.

i need this fixed as soon as possible as firefox remains my daily driver due to being the only browser that still has good plugin support and decent customization

Hello

Just to report Firefox 121.0.1 (64-bit) unable to upload any video formats on youtube and always having invalid video format error. I'm unable to upload even that videos what was already successfully uploaded some times ago. I using Microsoft Edge now to upload on youtube and it is fine with all my videos. Hope you can fix soon.

Hello all, When serving an animated HTML5 banner on Firefox the text or image is blurry Serving the same in Chrome or Edge is super sharp Attache is a sample showing the different results in each browser

Thank you for your help!

I've recently updated to version 110.0, and I immediately noticed an issue with my bookmarks where my scroll position in the bookmarks list isn't being saved after opening a tab or two. It keeps resetting back to the top of the list after a few seconds.

I don't know if this is a bug resulting from the latest update or what, but I know I didn't have this issue with bookmarks prior to updating to 110.0.

This is a horrible web browser that crashes constantly and is slow as hell. Even Internet Explorer is faster than this, and I am switching to that browser and am never reinstalling Firefox ever again.

Whenever firefox has multiple tabs open and on any single tab youtube is running i find youtube to crash lag and even crack itself by audio playing with struck video. FYI the same issue is not experienced in other browsers like brave for instance . I hope you provide attention to this problem and solve this issue as soon as possible and as I mostly use firefox to browse and use its dev tools.

On all sites where I need to login with my work account I get a tab crash when the browser redirects to https://login.microsoftonline.com/ac4b0eb0-811e-4ab0-acca-8a87079290dc/oauth2/v2.0/authorize?response_type=id_token&scope=user.read......

This is a recent failure (this week), that occured without any changes on my own account to Firefox developer version 121.0b2(64-bits)

I had to install google chrome to overcome this problem. Chrome has no issues with microsoft authentication.

Please solve as soon as possible, otherwise I will be switching to another browser.
