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?

For one of the client we are experiencing slow browsing issue with Firefox (Firefox 60.7.2esr) .We tried without any customization but it has the same slow browsing experience. However there is one observation though if we use explicit ip address instead .pac in proxy then browsing speed is fine. Our proxy team hasn’t found anything abnormal with proxy configuration and pac file size is also small in kbs.

Hello, I recently moved to Firefox from another browser and I am very pleased with it. My usage is that my computer remains on 24/7 with the browser open. I saw a paragraph in the help docs:

"Firefox's memory usage may increase if it's left open for long periods of time. A workaround for this is to periodically restart Firefox."

However this can be inconvenient when you have several tabs open that are logged in to various sites for work, which also retain state which is not restored when the browser is restarted.

Over a few days the memory "leaking" (?) is mounting up significantly as per attached. In summary:

Pre close - system RAM usage 12.5GB Post close browser - system RAM usage 8.1GB (4.4GB drop!!) Re-open browser with same tabs - system RAM usage 8.7GB (actually 9.0GB after all tab views were accessed and put back into the state they were in before closed)

From this simple test I can see that 12.5GB - 9GB = 3.5GB was hogged by the browser and not actually required.

As a developer I am interested to understand the reason for this memory leaking. Is there anything I can do while the browser is open to free it up? Or cause it to not "leak" in the first place?

Thanks,

Andrew

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

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?

Running Linux Mint, Firefox is latest version, PC has 8GB of RAM, yet when running Firefox gradually uses more and more ram till all is gone, only fix, close and restart Firefox.

Removed all addons, no change! SET Prevent Accessibility Services from accessing your browser to true, no change! Under performance set content process limit to 1, no change (I suspect this is a fake setting, it has no effect on number of processes!!)

PS Everyone else I know that uses Firefox has the same problem, is Mozilla trying to kill it?

Hi dear developers and people who help other people in this forum, I'm Kristian, an old user of Mozilla and since I have installed mozilla of quantum project on my laptop with windows 10, I have notice on the task manager that mozilla drains a lot of ram even with a few tabs open ( Let's say 7). Well my concern is because with Google Chrome (I know that is offensive to compare) I have open more than 30 tabs and its ram consumption is understanble to be higher, nevertheless is really close to mozilla ( Lets say 1GB of RAM). I tried to run mozilla on safe mode with no addons but I get the same result. I tried reduce the content process limit to 2 (4 by default) but again, the RAM consumption still high. I reinstall mozilla, but unfortunately nothing changes. Im the only one with this trouble? Any ideas of what it can be? The mozilla version what Im using is 60 x64 and windows 10 x64 Thanks in advance ps: I attach an image to prove what I wrote

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....

Firefox has become completely unusable for me because it has become very slow. It was fine on this computer (newer i7, 32GB ram, ssd) last weekend but not this. It is actually happening on two different computers. It becomes impossible to type (echo is seconds and windows reports that the application is not responsive).

However sysinternals procexp doesn't report anything much unusual for the computer as whole or FF. Speed test shows that my internet connection is fine and Chrome is working normally

I have paired sync down to only bookmarks and add-ons of which there are only 5.

The problem may be due to sync - FF seems to perform normally in safe mode or before it has asked for the master password.

I have a beef with visibility around sync - it doesn't seem to be possible to see how often it is running, how much data it is sending, how many disk writes are happening.

I am submitting this report from Chrome because FF is unusable.

Hi Firefox keeps on suspending when switching between different tabs (already opened or new tabs). When the FF is hang I can do nothing in the FF, but I can operate on the Windows (8.1) without issues.

I have already tried: - Put new Firefox portable - the same issue - Close other tabs - Disable EMET for Firefox - Prevent accessibility services from accessing your browser set to True - Security.sandbox.content.level set to 2 - Disable add-ons plugins and start in safe mode

Nothing of above helps. I would appreciate If you could provide the solution. I attached Troubleshooting information.

After powering up my computer, or completely shutting down firefox, it takes about 25 seconds for firefox to start (blank page displayed) then another 25 seconds to load. I have tried all of the options in help section (re-installed, reset, cleared extensions, changed start up page, etc.) but nothing helps. No problems with Chrome nor Internet Exploder, they both start up and load instantly. 64 bit Windows 7 professional, Intel i7-7700K CPU at 4.2GHz, 32GB Ram, GTX 1080 video card, MVMe boot. This machine is a screamer, except for Firefox. Also have a very slow Thunderbird but it is not nearly as bad as firefox.

When I have a video playing in the background (for example a Twitch stream) and use Firefox in a way that causes 100% CPU usage (for example navigating a Google Maps 360° view or scrolling a complex website excessively) I get interruptions and even repetitions of short bits of the playing sound. This issue started after updating to Firefox Quantum and is quite annoying. Is this a known issue? Any potential workarounds? I'm currently using 58.0.2 (64 bit) on Windows 10 16299.

Firstly, I want to say right away that the problem arose with the release of the 57th version, that is, Quantum. Until the 57th version everything was fine. And also I want to say that this problem does not exist in other browsers. The problem manifests itself in this case: If you open the site of the dns-shop.ru or technopoint.ru store and, without waiting for the page to fully load, click on any item on the page, for example, on the left, select the directory partition, then the whole browser hangs. In this case, the browser stops responding to any pressing in the interface and generally does not react to anything, except for the completion of the process in the task manager. That is, I open the task manager and find there a process of firefox that uses almost all the resources of the CPU. After that, I end the process and firefox starts to work and writes that the "tab has dropped" (image # 3) I noticed the same problem on other sites, in particular youtube, vk, fb. Also, with fast transitions between site pages or streaming video, the browser may hang and the CPU load immediately 90-100%. Tried it on a completely clean firefox, on a freshly installed one, it ran without add-ons. All the same. I have to use google chrome until it's fixed ...

On Windows 10 and Firefox 58.0.2, when I click the menu button in the upper right (the three hamburger bars) or any other menu button (i.e. history), a ghost of the drop menu appears and Firefox hangs for at least a few seconds. Often times, it totally hangs and needs to be closed. I can browse and scroll and video stream works. I have tried the "it hangs" fixes and none work. Specifically I have tried the accessibility permission option, the disable hardware acceleration option, and trying a new alternative profile (full on reset). I have also tried uninstalling the 64bit version and installing the 32bit version. None of this has worked. The menu bar does work. Also when any popup from the menu button area (i.e. giving website location access) it is ghosted or black and locks Firefox.
