How can I check what is being loaded on my computer with my browser Firefox when I start up Firefox. It takes too long for my homepage to load compared to other browsers. Can someone help so I can determine what is being loaded when I start up my browser Firefox? Thank you.

Firefox Desktop issue,

McAfee malware has entered the Firefox browser a couple of days ago claiming viruses have been detected & requires me to click on their popup to remove it. Additional warning follow and reoccur every couple of minutes. I don’t have McAfee Anti-virus software on my computer & have not installed any new software for some time. The anti-software I have works fine (Spybot & Microsoft Security Essentials) and detects no problems. The first application I initiate upon boot-up each morning is Firefox and that’s when the problem begins. It is somehow related to Firefox. I cannot find any processes in play.

I’m using Windows 7 Pro

Sincerely, [removed email from support forum]

I tried all six free malware scanning programs suggested but nothing found

It takes forever for my home page (MSN) to load when I first start Firefox. Can that process be speeded up? I suspect there's a way to get my home page to load faster. Can someone help? Thank you, Firefox.

I've been trying to connect to discord for a while, left it on for 2 hours and hasnt loaded. when i opened the console log, all it said was "Firefox can’t establish a connection to the server at wss://gateway.discord.gg/?encoding=json&v=9&compress=zlib-stream" all over. Please help.

Comments on YouTube videos are no longer visible after Firefox version 115.10esr update. They do however work on my other computer which also has Firefox but not an esr version since it has a more current version of windows. I tried deleting all cookies and cache, starting in safe mode, disabling ad-blocking on YouTube but nothing worked. I'm thinking of rolling back to the previous update but would rather have this problem fixed.

I'm running Firefox 102.4.0 ESR (32 bit) on a Win-7 (32 bit) PC.

It works fine. I visit a LOT of websites, it works fine.

Until just now. I'm trying to bring up namecheap.com (a domain registrar) and I'm getting this message:

Secure Connection Failed An error occurred during a connection to www.namecheap.com. security library failure. Error code: SEC_ERROR_LIBRARY_FAILURE

I'm not given any option to alter any FF settings or to otherwise create an exception to "trust" this site to be able to access it.

I've read where changing security.pki.crlite_mode (currently 3) to something else (like 0) and I've tried that, and unless I have to close and restart FF for that to take effect (which I have not done) then that setting doesn't fix the issue.

What exactly is going on here? Why is only THAT SITE giving me problems?

In recent attempts to join a few webinars I am now getting more and more "TLS Errors." I have noticed that many of the solutions to this problem involve actions that do not solve the problem but create larger issues. Do you have a solution that works safely? I am forced to use Windows 7 unfortunately due to work systems and a long story. I think this is my primary problem but I have to keep using it until the bitter end with this PC.

I appreciate your kind help. Thanks, Clay

All Add-ons are disabled and Firefox still can not play SOME of the videos on twitter. All I can see is a spinning circle on the center of the frame and the video will never be played. I tried other browsers and they all works well. It seems this issue has nothing to do with my network connection.

I searched this forum and find out some thread reporting issues of not playing All videos on youtube/twitter. Replies to these thread provided some solutions ,like update ffmpeg , set media related options in about:config. I tried them all and neither of them work for me.

I tryed Firefox 115.8.0esr and 115.9.0esr 32Bit on Windows 7. (78.15.0 works) Firefox crashes(the whole program, i mean no tab) on "about:support" or some pages on support.mozilla.org like https://support.mozilla.org/de/kb/firefox-leistungseinstellungen always reproduceable.

I disabled all Addons, i disabled this power optimizion setting, removed usercrome.css same. With Firefox savemode it dont crash. Spyware is blocked, means datareporting/telemetry/ping by disabling the options and empty the urls (like on FF 78 but it dont crash). Somewhere i read firefox can crash on a empty url, but i assume its fixed long time ago. A wrong, unreachable or empty url should not crash on well programming. Think about countrys that blocks urls, adblocker, pihole and so on. I dont remember about what url i read.

Does the savemode revert all about:config settings? What does support.mozilla ask the browser that causes the crash? It know it seems to identify the Browser, but usual its done by useragent and no "internal" communication.

Then FF always crash on ebay.de search if you scroll or change settings while the page is not ready. Spyware is too blocked by Hardware, ebay may wait for some ad? But thats already on FF78 but on 115 it seems more often, this was not with FF 52. But some sites including ebay stops to work with FF52/78 so no choice.

Hi, I've always run dual monitors with no issues. Since some updates to FF I've had an annoying problem. When I close FF, part of the last page I browsed remains frozen on screen. If I open up any other app and move it over the part frozen FF image, the screen corruption is erased. The problem has remained through at least the last 3 FF updates.

I've been searching everywhere for an answer to this annoying isssue which only ocurred on FF shutdown and not Chrome. Last week I tried a solution which seems to have worked, but I kicked myself afterwards because I can't now recall the web page with the solution and need some help other could benefit from to explain what I did.

I remembered clearing certain caches (?) using FF settings, then deleting or renaming certain json files in a (?) profiles folder which I assumed would be recreated on the next FF boot?

115.8.0esr (64-bit)

This newest release has a massive memory leak. I know it's Firefox, because I look at the system monitor, and there are even more entries for firefox.com running than usual. The first one on the top of the list is the biggest resource hog, and the next one is second. All the rest have something going on, but smaller. Looking at performance in the Windows Task Manager, under performance, the memory usage goes up. Right now, it's 5.35Gb of 16Gb. At worst, several days ago, it was at 12Gb. When I force close Firefox, the memory and usage goes way, way down, to a usable level.

I wrote last night. "Ed" someone got back to me, didn't quote my message, and said he was from another department. I DID EXACTLY THE SAME THING AS LAST NIGHT. I hit the blue button, which took me here, and he advised me to do today, which brought me here, AGAIN.

If this, again, goes to "restoring access to Mozilla accounts and subscription services such as Mozilla VPN", please be professional and forward it to the right department, possibly with my message quoted, as this is the second time I'm creating it, and only have my memory on which to fall back for the first time. The logical topic is "Fix slowness, crashing, error messages, and other problems".

At the same time, other releases have had big memory leaks, and they seem to get patched quickly.

Thank you again.

On one web site (see attachments), my location is being detected as being outside USA while using firefox desktop browser, yet on the same computer, my location is being correctly detected as being inside USA.

You will see the asian words. When I change the pull dawn tab ("Saudi Arabia") to "USA", the asian lettering does not convert to English.

Not sure how to fix this.

FireFox has been crashing for the past few weeks, that is not the biggest problem, but it also does that during a restore session. Which makes me lose everything I've been doing, the simplest solution I've found is reopening almost all of the tabs from last week, which is about 600 tabs that I then go through and get rid of what I don't need. That takes a lot of time, and my internet connection is not that good. which means that I will lose a large part of what I was working on the next time FireFox crashes during a restore session. Is there anything I can do to prevent Firefox from crashing?

greetings Iskander

I'm still using windows professional 7, it works for the most part. Unfortunately often the browser won't load or it will load and runs very slowly, then it shows a box saying close previous firefox. When it is running slowly I often have to hit the browser many times until the box shows up saying close previous firefox. Is this something to do with windows 7 or another completely different issue.

Dear Sir,
