I currently have version 72.0.2 and it is so slow.

I suspected an ISP problem although I have fibre optics but I just have to compare FIreFox with another browser to see that FireFox is the problem.

For instance, on the same site, I can call up a different page in around 5 seconds with FireFox whereas the same change of page takes well under 2 seconds with the Avast Browser.

Opening 3 tabs simultaneously in FireFox when I launch it takes YONKS whereas it used to load all 3 pages in a blink.

I already have add ons like "Disable HTML5 Autoplay" installed to speed up things.

What is the solution please?

FF will not load pages and I must shut down and restart for it to work if I leave it alone for a while.

If I am working online and leave for a few hours and then come back and go to open a new tab or even reload an existing tab or go to a new website using an already open tab, the only thing I get is the "spinning circle of death." I then must exit out of FF. Then when I go to reopen FF I get a window that says FF is still open, even though it is not and do I want to shut it down, so I click yes. Then I am able to reopen FF, but always get a message that says my user profile cannot be loaded properly, so I have click on that and reopen a second time. Then it finally opens and I am able to work fairly well until the same problem happens again.

I am really not sure what changed, but I never had this problem, I could leave FF open for days and come back and then open a new tab just fine and begin working again.

My PC runs fine and no issues, Recently upgraded to Widows 10 - no issues. Suddenly (and quite weirdly) I have this fault. I needed to activate new Reason software on Propellerheads.se site. The site loaded and I saw the image for about 2 secs and then the screen went black. The music I was paying continued (so I knew Windows was still running) but the PC was unresponsive - Alt.Tab, Start, Ctrl/Alt/Delete non of these worked. The Sleep button worked but when I woke Windows the screen remained black. Only recourse was a hard reset. So I tried to access Propellerheads.se with Microsoft Edge - it worked fine. So I uninstalled Firefox, made Edge default client and did the activation. Then reinstalled Firefox but still the same problem. I have reset default user agent, deleted all history/cookies etc, refreshed Firefox, run in safe mode, deactivated plugins. Still Propellerheads.se will not load successfully. I don't want to run Edge - my preference is Firefox - BUT!!!

Tried refresh, reinstall firefox, no anti-virus program, actually I have no programs, no plugins, no extensions. Added firefox to the windows firewall allowed through list (which I never did with my vista machine) Brand new i5 quad core 3.6khz computer with windows 8.1 All drivers are up to date. It did take 2 weeks to get windows 8.1 finally installed without locking up and having to reinstall for the fifteenth time by disabling all of Microsoft's built in spyware. It's been semi stable for 2 days now. When I install kaspersky av. it adds another couple minutes to firefox launch.

I was really excited about my new suppose to be faster computer but my 10 year old Q6600 2.4khz with vista is way faster and easier to use.  I know I can't be the only one in the world to have this problem.  I've been all over the internet and I see all the problems people are having with windows 8.1. I've got invitation to upgrade to windows 10 but that just locks up the computer again.  Someone, anyone please HELP!

Firefox 42 noticeable lag when I visit a particular site.

Hi Mozilla, This is the site http://www.deccanherald.com/. When I open 8 or more tabs on this site Firefox gets laggy. I right click on a link and choose open a new tab there is a delay of a few seconds before the right click menu appears and then another delay to open in a new tab. when I'm scrolling down there are more delays and when I move from tab to tab still more delays.

When I visit this same site in Internet Explorer 11 I don't experience any issue it works fine. My specs Alienware M14XR2 i7-3630QM, 8 GB RAM, NVIDIA Geforce GT 650M, Windows 7 Home Premium Service Pack 1 64 Bit .

Since installing Windows 10, it takes a full second or two for a scrolling move (e.g.) to take effect. I'll turn the scroll wheel, and it will take 2-3 seconds for the page to actually move. Same thing waiting for a neutral cursor to turn into a "live" hand. In fact, I'm writing this via Chrome, since FF has becomes so slow and frustrating.

Since a few days ago, maybe a week, Firefox is running slow. I have a few add ons. Now I try to log in to a course and cannot log in. I do run Malwarebytes every morning, and Kaspersky Labs almost every evening. I will contact my school and ask the web master about my login problem, also. But this will probably not fix the slow speed of Firefox. I check to see I have the latest version, about once per month. The Windows update service is configured to run automatically. I run W-10 on this machine. It is a Toshiba Satellite C75D-A, with AMD A6 quad core processor. Firefox is my default browser. I use yahoo most of the time for e mail and search engine purposes. The list of plug ins you show for my machine is correct.

I was in Ukraine from 2 October until 15 October, as a visitor. I observed that my machine (this one) behaved very strange, while I was there. When I returned, this machine began to function more normally. Maybe it was because of the different current voltage or something. I used a voltage adapter while I was there. Firefox was also slow, then, and it took a while to connect to one site or another. I had a lot of trouble to connect to the sites of 2 banks where I have accounts, but not to another bank, where I also have an account.

Sometimes I felt like my machine was not under my control, and a few times I saw the arrow (cursor) move on the screen, by itself. Like someone else controlled my computer. I reported this to the technicians at my anti-virus provider (Kaspersky Labs). They gave me a link to a program, and I sent the results to them. They ran a test and found nothing unusual.

Now Firefox is slowing down again. It works, yes, but it is not as agile as it once was.

Cookies are enabled in Firefox on my machine. But sometimes I use the version with a Venetian purple mask. I understand the cookies and history are not recorded or are disabled when I use this special version of Firefox.

I avoid Chrome due to the invasive and spying customs of Google. I use G mail sometimes, but am migrating my e mail to accounts in other providers, for the same reason.

I use IE for some sites that require it. Like the official site of Las Positas College, in Livermore, from which I graduated last year. Their site is essentially designed to work on IE.

One bank I check routinely, requires me to use IE to access my account.

I do not like to be tracked, so I have the no-tracking request turned on almost all the time.

If you need any further info, please let me know. Marc

When I'm typing in Firefox (writing an email for example) there is a delay of about ten seconds between the keystroke and the character appearing during which time the cursor seems to freeze. If I type several words in a row the cursor freezes like this and then the characters all appear at once but not at all in the correct order. They are too mixed up for it to be simply a mistake in my typing - the resulting text has all the letters that I typed but in a crazy order that looks like gibberish. This happens when Firefox is otherwise running normally (no other delays or freezes) and does not happen in any of my other browsers or applications. It significantly slows down my work and I prefer using Firefox but often am forced to switch to another browser to get my work done in a reasonable time frame
