I have just installed Firefox 57 (Quantum) 64 bit on my PC and my Laptop (both Windows 10 (1709)).

On both my machines, Quantum displays pages appallingly slowly and often freezes, when no tabs or the settings menu can be selected and nothing else produces a response.

I cannot believe that this software has been properly tested on users' machines at their homes - its deficiencies would have been blindingly obvious. Their is clearly a huge problem here.

I was so looking forward to returning to Firefox but it is a complete disaster.

Please find a fix soon or I will have to uninstall Firefox, maybe permanently. It is useless to me in its present state.

Greetings.

It turns out when I have Firefox Quantum focused, and leave it inactive for around five minutes, my computer goes to sleep.

That doesn't happen when I have it running in the background, or not at all.

It's getting frustrating, it happened quite a few times, and I now I am CERTAIN, that it IS Firefox's doing Firefox Quantum's doing.

Today Firefox automatically upgraded itself. After the upgrade, it is incredibly slow. Home page never finishes loading. Tried a simple page (google,com) and that loaded but nothing would work. Could not type in search bar. Could not access any of the Firefox menu (ie: help or tools) The upgrade also occurred several days ago and did the same thing. I did a system restore to get back to the earlier version. But again the automatic upgrade has struck.

I have been a Firefox user for years and am amazed that an upgrade could be so terrible! As a result, I have switched to Chrome and will stop recommending Firefox to everyone/anyone until the problem is resolved. After 25 years in the IT business, I do not wish to spend several hours troubleshooting a problem caused by and "upgrade"! I will attempt to start Firefox every once in a while to see if the next "upgrade" cures the problem. Until then...

Goodbye Firefox!

Sometimes the icon for Firefox in the dock turns into a light blue rectangle box with a thin white border around it and a capital "A" that is made from a pencil, paintbrush and ruler.

Sometimes in the past, it has helped to remove that icon from the dock and then start up Firefox again and then say "keep in the dock" and then the usual Firefox icon appears again and sticks, but that didn't work this time.

It's harder to identify Firefox if it doesn't have the usual little orange fox icon.

I have a Mac Mini (late 2014) running 10.13.1 High Sierra. This problem just recently reappeared, but not immediately after installing High Sierra.

I have searched around and can't find a solution for this.

I'm attempting to upload a screenshot of my mouse cursor pointing at Firefox in the dock and the generic icon.

Two days ago Firefox upgraded itself to 57 (Quantum). It worked fine, although without some add-ons that I depend on, and with a difficult-to-read color scheme. Tonight Windows updated itself and Firefox stopped working. The window minimized itself through a series of sequentially smaller windows until it was apparently just a few pixels wide and high. When I try to re-open Firefox I can OCASIONALLY get it to open a very small window and tried restoring it to its default state, but that didn't improve anything.

I'm running a Dell XPS 8700.

If you have any suggestions I'd like to hear them. I've been using Firefox for more than 10 years and I really like it, but this "upgrade" has been a fiasco for me. I'm currently using Edge, and I've downloaded Chrome which right now looks like my new browser.

Hi,

Last night when I turned on my laptop, Firefox automatically updated itself. Immediately, it was very, very slow, then stalled, and crashed. I reopened it a couple more times, but still the same. At one point, it locked up my computer. I restarted it with add-ons disabled, but that didn't help. I've also refreshed it, and that too didn't work. I've used Firefox for many years and have never had a problem like this. My OS is Windows 10 (64-bit) and the rest of the computer is working fine.

Thanks!

I cannot start Mozilla Firefox at all, no matter what I do. Nothing on the site so far has been able to help since everything assumes I can actually start it! The only thing that happens when I click Mozilla Firefox is a crash report, that's it. Nothing else, no screen flicker, no Mozilla appearing for a second or two, nothing but the crash report. I've been having this problem for about 4 days and haven't been able to fix it. The only thing I can think of is to completely uninstall Firefox (which I've been avoiding since I'd like to keep all my preferences if possible but it's looking more and more like I cannot).

Hi,

I upgraded my Firefox to 57.0 version today and now getting this error massage. I deleting the file profiles.ini and able to start the Firefox, but after closing it the error is constantly returning. I think that the problem is in the path to this file: C:\Users\Администратор\AppData\Roaming\Mozilla with word "Администратор" in it written in cyrillic letters. I tried to create new profile with path without cyrillic letters (with open firefox, because I'm don't able to start Poifiles Manager) and make it default profile, but Firefox don't remember my changes and after closing don't start again. This strogs my oppinion that the problem is in the word "Администратор". The previous versions of Firefox were understood russian, but the new version, I think, don't understand it. I have russian UI in Firefox. What i have to do now? (Don't tell me that I'm have to install the Chrome).

Best regards, Michael Shaphir

With the newest update 17/11/2017 while typing in the address bar or searching, firefox freezes and gives not responding messages.

It eventually followos through but this is not its normal behaviour and as a coder I would view this as a critical failure with a release.

Please fix :)

I'm ready to quit Firefox. I use Win 7 64 bit, have updated all my video drivers but to no avail, 57 continues to freeze. They supposedly made this faster and better but all I've had is problems. I'm not going to sit here and spend hours trying to diagnose something that worked fine before it updated automatically. What's the deal?

Firefox updated to Quantum and blows Win8.1 dual processor out of the water. Usage runs as high as 100% Here's a screenshot. I picked a dull website with no ads running etc. CPU usage spikes every few seconds and Firefox averages really high compared to Internet Explorer. Notice the regular spikes in usage don't correlate with disk usage so I don't think it's causing paging to occur. What has Mozilla done to Firefox to cause this?

I have Mozilla Firefox last version 57 I think, and every time I open the browser my PC freezes.

It doesn't freezes right away, it may think minutes to hours, but it will certainly freeze.

Some time sit happens with other browsers opened, some times it happens just with Firefox opened. But it freezes.

I'm using Windows 10 Pro x64, Anniversary Update, I think. Build 1709. I also have Eset Smart Security 10 as my antivirus.

The newest version for Windows 10 was just forced installed. Now it is terrible. Trys to open home page and dies. Comes back with Firefox not responding. After a while, it finally loads the home page. Your new version is going backwards in time. It is terrible. And I rely on Firefox for my internet connection and activity. I did your refresh and reinstall. Still garbage. Can I go back to the prior version? Your new version is horrible and I made no changes to any settings. Your force install happened and now it crawls to open up. HELPPPPPPPPPPPPPPPPPPPPPP Please
