Firefox has been my browser of choice for about 6 years. On 3/16 /15 it stopped working. I tried all of the suggestions. I then completely uninstalled Firefox and Mozilla Maintenance. I restarted and checked my disks and memory. All other browsers: IE, Safari, Chrome & Opera work fine. I installed from Firefox Setup 36.0.3.exe this morning. Same problem. Works for about 5 minutes and then hangs.

I just upgraded my computer to a 1 tb hard drive and installed windows 10. Now firefox doesn't work right, example: I go on Facebook or another site and when I try to type a post I have to type 2 or 3 letters, then wait several seconds for them to appear. I have re-position my cursor and type 2 or 4 more letters and wait again. Can this be fixed?

I have 3 PC's that have all been upgraded to W10, and all 3 have FF as their default browser (2 PC's home built the other is a Samsung Series 7). On all 3 of these PC's FF hangs for no reason, and even more baffling they all seem to hang at around the same time. Most often I will minimize FF and walk away from the PC only to come back later and not be able to access FF. When that happens the FF window is almost slightly blurry and the only buttons available in the window are minimize and close.

Yesterday I updated 2 of the PC's to FF 40.0.3 but FF still hung in less than 24 hours. The other PC is running FF 28. The only thing these 3 PC's have in common is that they've all been upgraded to W10 and they share some of the same add-ons. Any suggestions on troubleshooting this? I did try disabling Flash but that did not resolve the issue.

In the past weeks, suddenly my Firefox started behaving really weird - a few times a day the currently opened tab becomes unresponsive (you can't click or hover anything) but you can still scroll through them (at least a bit - after that point, it's just plain white). At these times, the cursor is the hand one, during the whole unresponsiveness episode, as if everything was clickable (though obviously clicking does nothing). You also can't close the tab during this tab - the only way is either to wait a good 30 seconds for it to unfreeze or to change to a different tab and close the unresponsive one. When you do change tabs, though, the newly opened tab sometimes disappears completely, with a radial loading circle appearing in the middle of the screen for a few seconds before it magically reappears (it does _not_ reload, though!). From what I've been able to observe, this tends to appear on content-heavy websites like Reddit, Facebook and YouTube most often.

What is happening? I haven't changed my browsing habits in the past weeks, nor have I installed any new add-ons. I've tried disabling the ones I have but it's still happening with them turned off. What else may I try?

The problem occurs while loading Dropbox Home folder.

I restarted Firefox in Safe Mode and everything worked fine.

I am trying to find out which add-on is causing the problem. After I disabled all of them and restarted the program the problem occurred again.

How do I fix this?

PS. With "freeze" I mean that it doesn't respond for a while. After 10 secs it's fine again.

I had Firefox Developer Edition running for ages. Always kept it up to-date. Now the latest update made it stop working AT ALL. There is nothing. The executable pops up in Taskmanager for a split second and then its gone.

I went back to beta. Worked for a couple days. Now an update came in: BAM! same thing! Now I have 2 broken Firefoxes on my PC.

Not even running the Profile manager worked!!

Back to standard version: Works

Hi everyone

I've been struggling with a Firefox (v52.6) sluggishness problem for several months, and since in the meantime I tried all fixes I could find suggested in these pages, I thought to try and seek help in the forums.

Firefox is still usable, but resource-intensive pages (e.g. Facebook, Google Maps) are slow to respond, and often freeze the Firefox window (the no-response mouse cursor) for a few seconds. Meanwhile, the same pages (and the same amount of total load, i.e. open tabs) in Chrome produce normal performance, which suggests the sluggishness is a problem with Firefox rather than a performance issue with my PC, which is of decent specs (8GB RAM, i7 CPU).

Typically, Firefox becomes more sluggish the more it's been without a restart, and the memory resources it uses seem to grow proportionately. However, even when it's only using a few hundreds MB (after a restart), it's still quite sluggish, while Chrome, with a similar amount of memory used, is just fine. Likewise, when after a while the RAM consumed by Firefox/Chrome goes up to >1GB (not sure if this is in itself normal or not!), while Firefox is crawling, Chrome is still fast.

What I tried, which did not fix Firefox's sluggishness (or only did so for a short while):

- disable extensions one by one, and even all at once

- disable all plugins

- start Firefox in safe mode

- ultimately, I used the refresh function, and immediately afterwards Firefox seemed to be as fast as Chrome. I subsequently reinstalled all my addons (which include ABP, Zotero Connector, Classic Theme Restorer, NoScript) and settings. The next day, it seems my joy was shortlived, as Firefox is back to its usual sluggishness.


I would not want to migrate to Chrome unless I really cannot find a fix for this problem. Can anyone suggest more things I can try?

Thanks so much for any help.

I've noticed this over the past several versions of Firefox for OS X, and under Mavericks as well as Yosemite, on 2 different Macs of Mine: a 2009 Mac Pro and a 2012 Mac Book Pro.

The issues are: sometimes Firefox will not create a new tab or window when I press those keyboard commands, and sometimes, I am unable to type into form fields. Restarting Firefox will remedy the problem, until it happens again.

Otherwise, I find Firefox to be a great browser! Thank you for producing it.

This is a fresh install (I uninstalled and removed all folders and registry entries before reinstalling). Ive run scans for infections.

Firefox is very slow to bring up pages (30 seconds minimum) while IE and Chrome are normal.

When I close FF, the firefox.exe process doesnt' close for 3 to 5 minutes ad then I get a "Firefox crashed" message.

I'm seeing this on a ton of machines (7 and Vista).

Please help!

Hi all, I'm using a MSI GF62-7RD laptop running Windows 10 64-bit, latest Firefox version (59.0.2 64-bit). For the last few weeks Firefox on my laptop has been taking years to load almost all web pages, while Internet Explorer on those same occasions was able to load the same pages in good time. The annoying thing is that Firefox on my desktop (Windows 7) is not similarly afflicted. And to make matters even stranger, my laptop when using other internet connections (at friends' houses etc.) is able to use Firefox without the speed issues I get at home.

This problem was also present intermittently on my last laptop (also MSI with the same OS), but now it seems to be a permanent state of affairs. I have variously in the past tried disabling accessibility services, refreshing Firefox, and doing a complete re-install (including deleting all Mozilla folders in the user's Appdata folder). Nothing seems to help....

Unlike other posters who describe crashes while trying to stream Netflix due to Silverlight issues, the movies will in fact stream, but so slowly they are unwatchable. The audio keeps going but the video freezes and then skips. This has only begun to happen with the last 1 or 2 Firefox updates, and the last update is what has made Netflix unusable. I've spoken to Netflix tech support and their suggestion was to install Google Chrome and use it to stream Netflix. I will do this if I must, but would prefer Firefox if you folks can come up with a fix for this.
