Firefox has begun opening very [very!] slowly, as well as crashing and freezing during use. This is happening on all of my three machines, two running Win 7 and one Win 8. I have tried refreshing and disabling hardware acceleration, but to no avail. Now it seems to freeze on opening and takes a minute or two even to become responsive, if at all. When I look at Task Manager during a freeze I see the Firefox process is using 35-50% of memory [i have 8GB, 12GB and 16GB] and up to 50% of processsor resources. All has been fine until the last couple of weeks. As an adjunct, in the last month I have noticed an almost permanent error message on the status bar - "Sync encountered an error while synchronising: Unknown error. Sync will automatically retry this action."

So, interesting opportunity to learn something new! ;) What is wrong: buffering. At first I thought I have problems with Flash alone, but this isn't true. Any video [be it on Youtube or Twitch, Flash player or HTML5 player, doesn't matter] randomly will stop. I will see the buffer "icon" and... nothing happens. Ever. I can leave it for as long as I want, it will not budge. On Twitch.tv it's a bit different, it will pause the stream for a solid minute and then "restart" itself.

Cleared cache, session files, updated Flash, used Ccleaner as well. Don't want to go through creating a new profile yet (a bit of a hassle), trying to figure out what might be causing the issue. As I said, it's very random, sometimes happens in short video on Youtube, sometimes I can watch long videos without much problem. And no, my internet is not the issue, double checked on that.

Any ideas?

Firefox crashes constantly. Tried starting it in safe mode, and then disabling the javascript-line. Helped for a few days, but now the crashes are back

I'm running Firefox 59.0.2 64-bit on my PC. I have extensions for AdBlock, Honey, and LastPass. In addition to the two plug-ins provided by Mozilla in this version of Firefox, I have added Flash Player (re-installed several times).

I can't see ANY videos at all. No YouTube, no types of video at all.

I've refreshed my Firefox totally (and don't want to do that again any time soon!).

I've looked at "solutions" provided online, and nothing has worked.

Will someone give me the exact setup that should allow me to watch videos? Right now, when they come up, I get a spinning circle until finally some type of error message appears. The error message differs depending on where I'm watching the video. For example, If I'm trying to watch a YouTube video, I see the still picture that accompanies the video. When I click on the "play" arrow, I get: "An error occurred. Please try again later. Playback ID: pcGJXEDjuz-BRuBz" If I try to watch something on, say, the Weather Channel site, I first see the still picture. When I click to "play", I see a black screen with a small blue square in the center with the Weather Channel logo.

I did have a big Microsoft update a few nights ago, but I have no idea what changed there.

Bottom line: I have no idea what has happened to my video. What has changed since Firefox 58?

I've cleared cookies multiple times

I've emptied the cache

I cleared my download history, and a majority of my browsing history

I've tried having hardware acceleration for both flash and firefox on and off

I turned off all my apps and plugins and when that did nothing I turned back on the ones I need. I never had a lot of apps to begin with. only a max of 5. I had quite a few plugins, but i disabled all but quicktime, flash, and silverlight. I have those three set on "ask to activate" so none are "always active" anymore.

I also tried a couple things from the FAQ and forums here about changing a few settings in the "about:config" setup.

A few of the above things initially worked, but after a day or two it'd be back to sucking up my CPU and memory. I would then try the same thing again, and this second time there would be no improvement. The real memory will fluctuate between 200 MB and 1.7 GB, and has done so for quite a while.

Even after I've left streaming sites, and sites with lots of images, and I'm not downloading anything, the memory and the CPU will still do that. I only have a handful of tabs open at a timeusually, and all of them are mostly text. I'll quit and reopen firefox, which will initially bring the memory and CPU usage down, but it inevitably climbs up quite quickly, regardless of my tab usage. It'll be the same if I'm playing a flash game or scrolling through blogs.

I never had any of these problems with Firefox 23, and my internet usage habits haven't changed at all. I had some of this slowness a few times with version 24, but nowhere near as bad as this, or as constant. Almost everyday I end up googling for other ways to speed things up. Everything I do never slowed down Firefox on earlier versions.

I've tried all my usual tasks on Safari which will never climb above 30-40 MB of memory, even on netflix streaming, or flash games, and the CPU will average around 8 and 11%.

Hello, I am writing as I am experiencing some issues with my favorite web browser after updating to Windows 8.1. Here are some details. I updated from Windows 8.0 to Windows 8.1 and ever since Firefox has run somewhat strangely. In particular when on sites with a lot of images like Facebook. It is like there is some kind of Flikr effect between the desktop and the images and between the images and the browser (almost like old 16 bit video games flikering). It is not too bad but it is an issue. I have tried resetting firefox and restarting the computer. I haven't tried a repair, and I haven't done an uninstall yet.

Every time I go onto Youtube to watch videos I can hardly even watch the videos. This glitchy mess usually happens with videos that aren't constantly in motion, like a very static slideshow. The glitch affects the video area only, and appears like 2/3 of the video has bee stretched like it's being smeared or is "raining pixels." In a few cases it's a lovely dithered effect that looks like a teenaged girl's first go with eyeshadow. For the love of all that is holy, PLEASE HELP. I am but a poor whelp that is being fed videos through an IV daily, and I cannot take my hits when the smack is so trashy.

Sorry, I took 3 screenshots but firefox isn't accepting them for some reason ...

So recently my Firefox browser has been leaking memory like crazy going up to 1.7 GB in used RAM. It starts off fine when I first open it, but progressively gets worse over time, making scrolling a choppy and painful task. This started with version 28.0 but I've since upgraded to 29.0 and the problem persisted. I've done hours of research on the problem and have tried all the following solutions, to no avail:

- Turning off hardware acceleration/smooth scrolling/auto scrolling - Creating a new profile - Completely uninstalling and reinstalling Firefox - Running it in safe mode (still lagged, even in safe mode!)

Has anyone found any real solution to this problem?

These include *checking my ram *disabling hardware acceleration *reinstalling Firefox *Turning Adobe flash on to ask to activate. These problems are more prevalent on videos (more than just YouTube) but do still happen when just browsing the internet, I think something is getting overloaded and breaking but i have no idea what.

Hi, When I launch Firefox, I get error "The application was unable to start correctly (0xc0000022). Click OK to close the application". It was working a couple days ago. I suspect it did an automatic update and now it suddenly stops working. If I install Firefox version 48.0.2, I am able to start Firefox immediately after the install, however it automatically installs an update (possibly to version 49) and when I relaunch Firefox, I get the above error.

Please help. Thanks.

I am running Firefox 55.0.3 on an iMac El Capitan. I keep getting Access Denied; you don't have permission to access (URL) on this server, for a few sites only (sites I've accessed in the past). I've cleared cookies, cache, and history, I've refreshed Firefox, I've disabled all add-ons/plug-ins/extensions. I've also tried the sites with other browsers (so, yes, I know it's not just Firefox, but I was hoping maybe you could help anyway...) Thank you.

Was there a recent change that invalidates private certificates, with it's private CA imported into my FF CA repository?

What I have set up, which worked not too long ago, which was defining the IP address and host name in C:\Windows\System32\drivers\etc\hosts file. Then importing the remote site's private CA certificate in FF. From that point on, it trusted my private URLs due to matching private CA. Now, generates SEC_ERROR_BAD_SIGNATURE.

I renamed the cert8.db file and restarted FF. I now get the normal "untrusted" error then re-imported the private CA to make the "untrusted" error go away. However, that still gave me SEC_ERROR_BAD_SIGNATURE. So, something must've changed.

I even tried disabling OCSP checking (thought it was optional if it couldn't check). I then disabled OCSP Stapling. Neither resolved this issue, thinking it was trying to check with the OCSP server, which it can't reach due to firewall since it's internal to the other private LAN.

I'm not sure where to look. I tried Googling for answers, which lead me to the above two solutions to try.

The CA I have is a private CA, generated by Microsoft Windows Server 2008 R2 with the Active Directory Certificate Authority installation. Like I said, it was working in FF fairly recently. Let me know what else you need for me to provide.

Hi all,

I've been using Firefox since Netscape and all has been fine - using it last night and everything was fine. Then all of a sudden, Firefox won't start up today (there has been no Windows updates). When I click on it, the icon does not show on the task bar, the Task Manager shows Firefox briefly then it disappears (Details tab) and there are no error messages. When I boot into Safe Mode, it loads up and I used the Mozilla Refresh Firefox while it was up in Safe Mode but when I return back to my normal Windows 10 environment, it won't start up again. I've disabled Norton Anti-Virus and tried launching with SHIFT pressed and still no go. I've rebooted many times and even uninstalled and reinstalled the application. My work laptop still runs Firefox fine, just my Home Desktop is having this problem all of a sudden. I'm running Windows 10 1703 64bit. I'm at a loss, please advise, I don't know what to do now. (unfortunately I'm accessing these forums with Edge right now)
