Firefox Support Forum

Hiya, I'm hoping someone here may be able to help. I originally posted on the microsoft website but they were unable to help and said I should report to Firefox. I'm not sure how to do that so I'm hoping posting on here will get me an answer. I'm also unsure how to add a link to the forum I was using so have done a screen shot. Hopefully thats ok

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?

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.

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?

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.

Since the most current Firefox update in June 2022, when in Yahoo Mail and downloading an attachment, as the download complete, the Yahoo Mail tab is automatically closing, requiring I to go to 'History', then 'Recently Closed' tabs to re-open it. This happens Every.Single.Time I download photos and scanned docs from email. Again, this has never happened before - only with the recent Firefox update. I have 2021 a MacBook Pro.

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

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?

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?

Greetings,

My Firefox keeps crashing randomly even though it's a new PC with very capable good hardware. My old laptop used to run 100s of tabs without any issues.

However, on this new PC, the crashes are fucked even though I barely have about 20 tabs open.

Here are some crashing reports:

Recently, when I use this browser, some of my Yahoo emails received are garbled and resemble computer code. But I don't have this problem if I use Chrome or my android phone. It is a recent problem and does not affect all my emails.

When Firefox is launched to maximized, the Windows Taskbar does not display when the Taskbar is set to Hide. Firefox takes over the entire screen. When I use two monitors and Firefox is on the second monitor it the toolbar is visible.

How can I stop this from occurring?

Hi,

As the title says, Firefox throws "We can’t connect to the server at m.imdb.com." error every time I try to open a page while everything else works like Chrome, Edge and when I ping via command prompt I get replies and other applications. (Win 10 64-bit with latest Firefox)

I think it's a system-wide problem but I can't figure out where. I was under the impression that it's a DNS problem but it doesn't even open IP addresses like 192.168.1.1 and it doesn't open instantly, no matter it's Google.com or my router IP, instant error message.

I tried everything I could find which are:

• Refresh, clean re-install with deleting profile directory
• clearing cache and data
• Toggling these in about:config: network.http.http3.enabled, network.dns.disableIPv6, network.dns.disablePrefetch
• Enabling/disabling my adapter
• Running a couple commands:

   ipconfig /flushdns
   ipconfig /registerdns
   ipconfig /release
   ipconfig /renew

   netsh int ip reset resetlog.txt
   netsh winsock reset catalog
   netsh int ipv4 reset reset.log
   netsh int ipv6 reset reset.log

• Setting proxy to None
• Restarting with Troubleshoot Mode (add-ons disabled)
• Removing Firefox entry from Windows Firewall. (I haven't installed any Firewall and Anti-Virus)
• WIndows's Network Reset
• Rebooting machine and router

I'm sure there are more, these are all I can remember now.

This happened some months ago but can't seem to remember how I fixed it.

The only way it opens sites is with a VPN that sets a system proxy and setting Firefox's proxy to "Use System Proxy Settings".

Cheers

Dear Sirs,

Since mid-November 2022 I encounter a login failure issue with my Wordpress website. I get a "500 Internal Server Error" when I try to login. This happens only on the Firefox browser. All systems components are up-to-date.

I tried: - cleaning cookies and cache, - logging in private windows, - logging in the Firefox Troubleshoot mode.

I spoke with my web hosting service. They had the same issue with my website. They said that recently this issue was brought up not only by me. No solution so far.

Are you aware of such an issue? What more could I do do eliminate the issue?

I would prefer to continue editing my website using the Firefox, as always.

Best regards, Mike

Firefox quit working. when I click on the Icon on my computer desktop I get the following pop-up window. Windows cannot find ‘C:\Program Files\Mozilla FirefoxFirefox.exe’

When I click on the Icon in my taskbar I get this pop-up window . Windows cannot find ‘C:\Users\hgmv8\AppData\Roaming\Microsoft\Internet Explorer\Quick Launch\User Pinned\Taskbar\Firefox.Ink’ Make sure you typed the name correctly, and then try again.

I have downloaded the latest version of Firefox but still get the error messages

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 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.

Hello
