Firefox Support Forum

I have been receiving the following error code 'PR_END_OF_FILE_ERROR' on several website on my Firefox browser. Sometime, not all the time, I get the same error message while trying to use YouTube, while other times the site loads but says that I am offline and no internet connection. I have done all of the fixes that they say to use online and nothing seems to work. YouTube will occasionally work but none of the thumbnails will show up. Then there are other site that work fine.

Hi, I am using Firefox vsn 120 for Linux Mint. I believe that I have the privacy and security set with the default settings.

However, Firefox seems to forget the information stored by websites, so that can't simply login.

Each. And. Every. Time. I have to go through the process of re-introducing myself to the security of the website provider who insists on sending me emails, SMS messages, etc. with codes to confirm who I am.

This applies, every time I use a site that requires a login (bank, BBC, Fidelity, eBay, Facebook....).

Once I have been approved on a site, then my login seems to work for a few days, up to a week and then off we go again with a new set of security codes. My settings do not delete cookies, and firefox is never closed, except if the PC needs a reboot, which is rare.

I would appreciate any help in settings that would allow me to use Firefox normally without having to enter security codes. Cheers, Mark

Why is Firefox suddenly not remembering any of my logins or passwords? When I go into Preferences > Security, the box to "remember logins and passwords for websites" is checked. When I click on saved passwords they all are there. The do you want to save box is there if I have changed a login, or added a new web site. I am not in private browsing mode. The problem seems to happen every time I install the latest Firefox update, or Windows 10 Pro updates. Some of my apps want to know if I am using a new device.

So I just picked up a new laptop (ASUS Vivobook 16x), and everything is fresh on it. Additionally, this only affects some video content in Firefox, with Edge browser unaffected. In brief, what is happening is that within a couple hours of having the browser open, certain video content stops working, specifically Twitter/X videos just spin, YouTube previews stop working, and videos continually load. Netflix videos continue to work, but hover previews stop functioning. I even check the 'Stats for Nerds' on YT and it shows 0 KB network activity in Firefox.

I've tried every basic action I can think of:

• Turning off extensions (only use Ublock and Bitwarden)
• Browser Refresh (x3)
• Reverting from 120.1 to 120.0, and now 199.0.1
• Clearing the browser cache
• Reinstalling NVidia and Intel Drivers
• Running in Safe Mode

Only by doing a refresh or completely closing/opening the app gets videos to function again. This doesn't affect the old laptop or my desktop, which makes me think it's a rogue driver--but then why would Edge function without error over the same period of time?

Are there any settings to play with in the browser that can help diagnose?

When I sign in on my Microsoft Account FF Password Manager Does nothing. I open up the passwords but the manager does nothing. How do I correct this? It is as if FF does not recognize I am being prompt for login info. This only happens with this cite. Thank You for your time Mike

HOW DO I STOP the background from being black? I can't read the URL i am selecting to copy in the URL address box. In prior versions, the use systems color option used to work. Now it doesn't. Plus the pull down that shows up is the most god awful seaform green i've ever seen. I WANT MY SYSTEM COLORS BACK

I have two monitors, and I usually keep a stream/youtube video open on the second monitor while I browse the internet/play games. I used to do this all the time in OperaGX, but I recently changed to Firefox, and I've noticed that after about 10 minutes, the video or stream stops playing, and I have to manually pause and unpause the stream to get it running again. I have checked online, and I found a fix related to the about:config setting "network.http.throttle.enable" as "false" and the "network.http.throttle.version" as "1", but my firefox already had these settings like this.

Stop tabs from automatically refreshing to top of page. Many people have this problem and I don't find a fix. One article states to go to Options and "Warn me when websites try to redirect or reload the page," but I can't find options.

After my PC rebooted, firefox will not open unless I rename the EXE to something else.

Steps already taken 1) Refresh firefox 2) reinstall firefox (including after wiping all data from PC) 3) delete parent.lock 4) check Microsoft account - I am NOT content filtering. I am the sole user in my "family" and the app lists me as the organizer. I have zero way to even set UP content filtering.

I am at my wit's end. I can't set it as a default browser because the EXE doesn't match.

Got a problem on two separate computers: Mozilla Crash Reporter keeps popping up when Firefox is not even running. I'm guessing that my antivirus avast is interfering with the update service. I'm I right or wrong? Otherwise, does anyone know how to interpret this? This is the report:

Hello, my bookmarks including the bookmarks bar have disappeared, within just a few hours of them being visible. When I clicked on the View menu button and selected Toolbars, the setting was somehow changed to Never Show. I changed it back to Always Show, but I'm curious how it would change itself to Never Show. I haven't completed an OS update for several days, and this incident just occurred today. All day long, my bookmarks were present; I turned off my computer about 5PM. When I turned it back on about 8PM, the bookmarks were gone. Help and thank you.

From: Dell XPS 13 (5 years old) on Windows 11. Up to date with The most recent version of Firefox which I believe is 120. Always stay up to date.

To: Dell XPS 13 (brand new as of this week), Windows 11 with all updates and Firefox most recent 120 again always up to date.

I have tried reading several articles on here and using different methods from multiple answers and threads and have failed to find a method which exports All of my bookmarks from my old computer to my new computer.

NOTE:

Would highly prefer a method that replaces all bookmarks and data on my new computer exactly with everything from my old computer!

I don't care about my bookmarks on my new computer because I don't really have any but I do care very much about my old ones. At one point when I was syncing them, The bookmarks on my new computer which didn't include The vast majority of them disappeared from both computers for a short time until I restored to a specific different date a few times and luckily have my bookmarks on my old laptop still.

I have tried exporting them as a JSON and as an HTML to put them on my new computer. I've read the HTML method puts them all in one place as opposed to replacing all of them. Obviously I would prefer the JSON method. However I have tried both with no success. I've also tried moving them into the documents folder both times as recommended. I've tried to restore to date on the new computer.

Transferring bookmarks individually would be way too time-consuming as I have a ton of different folders.

Someone please help me find a solution to do something which should be basic which is transfer all my bookmarks for my old computer to my new computer. I'm also logged into my Firefox same account on both computers and have tried syncing with no success as well. No matter how many times I do it. I repeated all of these processes many times with small variations.

Please someone help me get my bookmarks! Thank you for your time and help!

Best regards,

Nate

Whenever I change my VPN (not Mozilla VPN) status, Firefox will refuse to connect for something like 30 seconds then times out, leaving me with a blank screen. I have wait until that interval has passed before I can retry, otherwise it will repeat the freeze. This happens whenever I turn my VPN on/off or switch to a different VPN server. It happens only with Firefox. Chrome and my email client have no problems whatsoever. I think it's some kind of DNS caching problem within Firefox as the problem doesn't happen if I visit a site that I hadn't visited very recently. There's immediate response if I do that. I have DNS over HTTPS and secure DNS turned off in the settings, so it can't be those.

Anyone else have this problem? I wish there was some way to clear Firefox's DNS cache other than having to go into about:networking

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 am trying to go to ace hardware site. I get: Access Denied You don't have permission to access "http://www.acehardware.com/store-locator" on this server. Reference #18.26761cb8.1701661935.890df303 .
