Firefox stops working several times a day & cannot access websites. PC is connected via Ethernet to the modem/router. I get a message website cannot be found. I called the ISP a couple times & they show me connected to the internet.

Firefox will not completely close & let me run it again. Task Manager lets me remove all but one occurrence of FF, which prevents me from running another copy of it.

I end up restarting the PC several times a day to get connected again.

The last time I was looking in Control Panel > Network Connections & that window froze & could not close out of it. I could open FF over the Control Panel window but could not run FF. I let it sit while using a wireless device to look up stuff. The monitor went to sleep because there was no signal, probably because the PC went to sleep. I could not wake up the PC & had to power it off.

Another time Network Connections > Local Area Connections was stuck on "identifying..." and never found the router.

All this started happening after I tried a USB wireless adapter & installed its driver & Cisco software that got installed with the driver. I have uninstalled all this & updated the wired network adapter driver.

I tried to restore Windows back to an earlier date a couple times but a message said the restore was not successful.

Any suggestions would be appreciated, Thanks

I am facing a strange issue where the Browser doesn't load the website for a minute and shows server error. However, this behavior is not specific to any website and the server error shows randomly. Sometimes the browser loads the website normally while other times it shows server error. Please check this screencast: https://jmp.sh/jEu4D9k to understand better. So, I initially tried to open calendly.com and it didn't load despite my multiple reload attempts. However, when I tried to reload it after a minute then it came to life.

I have been facing this issue for many months and I tried almost every solution I found on Mozilla community pages like Resetting Mozilla, Setting No Proxy, Turning Off IPv6, DNS Prefetching Changes, Turning On/Off hardware acceleration, Uninstalled Mozilla and Installed a fresh copy, Changed to Mozilla Developer Edition, etc. but no luck. Please note that the other browsers are working fine and don't have any issues.

Hello, Firefox takes more than 30 seconds to load. Thunderbird is also slow. I've had this problem before at the end of last year. After a while it got better. But now I have to wait again. I scanned windows with various anti-virus and anti-malware programs. I have absolutely nothing. I only use Microsoft anti-virus. I have run many repair options on the net. I have also uninstalled and reinstalled Firefox. This long wait to load before I can use the software is really irritating. Internet Explorer starts within 3 to 5 seconds including the display of the first page. Best regards Otto Haldi

Firefox huge memory consumption - who's lying ?

I try to keep always open some tabs in Firefox,, probably already too many (it's not unusual to have 25-30 tabs opened, each having it's internet page). I'm using Firefox up-to-date on Windows 10 Home already at version 20H2.

So, quite quickly Task Manager comes to report that Firefox takes 1400-1600 of RAM (out of the laptop's total of 6 GB). At the same time, Firefox's internal Task manager pretends that memory taken by all tabs does not sum up more than cca 650 MB !!! This is concur with about:memory tab if I try that too.

Here's a capture taken with Snip&Sketch having both Firefox's tab with it's internal task manager, + Windows's Task manager over it (attached).


I feel like I'm cheated here, but ... who is most closer lay blame on ? Who is more likely to lie in this case ?0 Firefox or Task Manager ?

I tend to believe it's Firefox, but I'm willing to have other opinions. Are there extra memory taken by Firefox that is not reported in the about:memory tab, or in it's internal task manager ? (I'm onto this, I believe that there is something that is not reported, but so far have not a shred of evidence on this).

This is exactly why on my computer at work (on an OpenSUSE install) I gave up on Firefox and turned to Chrome, because on this one I can trust the internal task manager, and it does not crush my Linux box like Firefox eventually have done with it's crazy memory consumption and/or CPU huge load from time to time. I am still using Firefox on the home Windows 10 laptop because I share it with my wife, and decided she is to use Chrome, and myself Firefox:-)

Firefox slow to load, 20-30 seconds. Appears is opening more than one instance with a single click. When it does load it sometimes comes up with the last page I had open even tough I closed it out properly. Sometimes get error msg that must close out 2nd Firefox before can start Firefox but saying yes results in the current open window closing. This started yesterday and the latest version of Firefox was automatically installed yesterday? Window 7. Cleared cash. Disabled all add on's etc. No help. Close out Firefox and Task Mngr show no Firefox running. Start Firefox and Task mngr shows four/five Firefox running. This started yesterday and the latest version of Firefox was automatically updated yesterday. Any ideas.

Due to my work I often have several tabs open for upwards of 12 hours at a time. This being said, for some reason after roughly 8-14 hours of being open my internet slowly gets weaker and weaker, it never completely turns off, and the internet works perfectl for my browser, however other programs (discord, photoshop, minecraft, anything that uses a passive amount of information) slow down until I restart firefox completely. It sometimes slow my 70mb/s+ upload/download to .1mb/s measurable upload/download and if i can fix this somehow that would be wonderful.

I have used FF for years, now V82 on W7 starts out fine, but bogs down to point you can not type. I have tried all the fixes noted here without success. Monitoring both Windows Task Manager and FF Task Manager shows nothing unusual when this happens. Internet speed is 100MBS.

Turning off addons, limiting Tabs, clearing history, updating drivers, minimizing background programs, etc., has little or no effect. FF just bogs down, and usually doesn't recover until restarted.

This appears to be particularly noticeable on ebay, but does happen at random on other sites. Where else can I look for a clue to what the problem is?

Laggy when doing moves on Board Game Arena

A month to a few weeks ago Firefox started being laggy when switching tabs; also Facebook and Facebook Messenger; on Board Game Arena and also on Discord desktop app (using Electron/chromium) typing was getting laggy. I thought it might be hardware so I tested the memory with memtest86 but that passed. I also tried safe mode on Firefox but that made no difference.

So I reimaged my HD to a known good copy from December 2019 and then also recently to 2018 and updated to latest version of Windows 10. All seemed well but recently again Firefox has gotten laggy. Even typing in here it occassionally hangs.

I've attached a Firefox Profiler link https://share.firefox.dev/2Zlua5o if that helps with me doing moves on https://boardgamearena.com/ website with each move taking several seconds to do.

I have also the profile with more private information if that helps.

Can anyone help me troubleshoot?
