Firefox used to be a GREAT tool. Now, it is LESS than great. Firefox previously would load a web page in very short order (never really timed it) but it was in seconds. NOW it is more like MINUTES and that is just when it starts to indicate the page is STARTING to show itself on the screen. Has YAHOO insert itself into your programming?

Occasionally, any piece of complex software will stop responding, and need to be forcibly shut down. I had such an event today when the right-click (context) menus and title-bar menus wouldn't appear. However, since upgrading to FF 57, I now see about 6 Firefox tasks and 6 firefox.exe processes in the Task Manager (Windows 10).

I like the feature of being able to restart Firefox (after killing it) and have my previous session restored, but the processes aren't really distinguishable in Task Manager, so I don't know which one to end/kill. I had to kill a few of them today before I stumbled upon the "main" process and Firefox disappeared. Can you help me to identify the main process for next time?

This has been an ongoing problem that started, first with update 63.0, and continues with update 63.0.1.

I have tried multiple fix suggestions, including the very disappointing "refresh Firefox" option. While that did nothing to cure the problem, it did wipe out every saved password. That, to be blunt, really ticked me off. It says this fix solution will keep our saved information, with no mention of erasing passwords.

Second, I changed the Network Settings as directed, from Use system proxy settings to auto-detect proxy settings for this network. I have been cautioned NOT to use the no proxy option, because it has a chance of rendering some websites unavailable. Not interested in messing up my browsing experience any worse than these recent Firefox updates have accomplished by themselves.

All these problems aside, my biggest disappointment is in the total lack of communication from Mozilla. While I value the Firefox ideology and the mission to provide a more private internet browsing experience, all this is worthless to me if my pages load at something akin to dial-up speeds.

At this juncture I have no choice but to use Google Chrome until someone can provide me with a workable solution, a solution that doesn't send me back to square one with all my saved Firefox information. If that is the only remedy, I might as well switch my default browser now and begin to re-acclimate myself to the changes.

Thanks.

Everyone I know, and many reporters, here, are having memory leak problems. Hopefully, this will be repeatable, for you: - Run ff, with a single tab, and go to: weather.com, - run Task Manager, and watch cpu head toward 90%, and memory all get consumed.

This is on a Win10 box, clean install, with new install of FF57, and no add-ons. Same issue on Win7 box, which has worked fine, for many years, until 57 came along.

Topic title covers most of it.

Basically:

A few days ago, Firefox started running extremely slowly. Tabs take considerably longer to load, the browser becomes laggy when it tries to load anything, and attempting to open multiple tabs at once leads to Firefox becoming completely unresponsive for some time.

Attempting to refresh had no effect. Safe mode made it run at full speed, but disabling all add-ons did nothing under normal circumstances. Disabling hardware acceleration caused Firefox to go from "unusable" to "frustratingly slow". Disabling WebGL had no appreciable effect. Installing new drivers for my processor and graphics card had no effect. Restarting my computer had no effect. Removing cookies had no effect. Clearing the cache had no effect. Disabling Sync had no effect. Reinstalling Firefox by renaming the old install to "Old Firefox" had no effect.

I'm using Firefox 46.0.1, 64 bit.

I can't provide info on my plugins right now, as I'm posting this in Chrome because of how slow Firefox has become.

A speccy snapshot of my computer is right here: http://speccy.piriform.com/results/vUlsCY1KK83gUZAKOebuwys

I keep getting the message "Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system."

I have tried uninstalling and reinstalling. Deleting and reinstalling. Installing on a different drive, etc. It was working fine, then one day, that is all it will say. I'd tried making sure the folder isn't read only. I've also looked for the parental lock folder to delete (and shown hidden files), but it does not exist on any installation that I've done. Running out of solutions aside from the idea that maybe firefox is just broken.

I've also scanned for malware (malwarebytes), spyware (spybot) and done virus scans (AVG Free 2015).

Had a similar problem with IE, but have gotten it fixed by uninstalling and using windows update to update step by painful step from 9 to 11, and remaking my stupid icon.

Windows 7 SP1 Ultimate with all updates. Very nice hardware (but still a slow boot), which makes me still suspect malware of some type, or maybe AVG deleting something important.

Firefox v55.0.3 64bit is extremely slow in loading pages (so slow that I'm using IceDragon in most cases). I looked up increasing performance by using Hardware Acceleration by increasing the Content Process Limit (see attached). I have Hardware Acceleration selected. However, the selection for Content Process for my version of Firefox is set to one and the option is grayed out so I can't change it.

Any ideas on how to increase my performance? Running Win 10 Pro 64bit CU with latest updates.

This started over a week ago. I try to link to a webpage (either from a link on another page, a bookmark or an email) and I can end up waiting for over a minute for the page to load. I have checked my PC's Internet speed (excellent), malware and viruses (none), firewall issues (none - in fact, the problem persists even with the firewall completely disabled), I've even upgraded my modem (no change). The problem affects Firefox and also Chrome and IE. It does *not*, however, affect my laptop or notebook. I'm at wits end at this point and any other ideas to fix this would be appreciated.

I had been having problems with firefox since a few months ago. When I opened it, it worked really good, but two or three hours later it got reeeally slow, and when checking the Windows Task Manager it said that Firefox was using about 2.5 RAM GB and I had to restart Firefox. The real problem started when I got sick of the previous issue and tried to fix it. and what kind of fixed that problem was refreshing Firefox (reinstall it didn't worked and I say "kind of fixed it" because only made the problem to take a bit longer).

I was so happy that I got like 5 hours on Firefox but then it got slow again and tried to restart it but... Firefox didn't do anything, just kind of freezd in the start (see image below). In this stage, won't even try to load anything, if I type an address and press enter, it won’t do anything, I can open the menu and open tabs, windows and private windows but all of them are the same. The only way to close firefox is by this menu (the X button in the top right corner doesn’t work). I can’t even load the add-ons page, nor the settings page. I have access to the help menu to refresh firefox but that fixes the problem only for one session (if I close and/or restart firefox, the problem returns).

I tried all what is said here: https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems but didn’t work or worked just for one session (reinstall, refresh and new profile solutions work for a single session, but the problem with the RAM persists, doesn't even work with safe mode).

I tried the solution given here: https://support.mozilla.org/en-US/questions/1021896 but won’t work not even for a single session. I neeeeeed help! Thanks!

I first noticed this in Overwatch (OW) but also with Diablo 3. These are the only games I play online. OW has a inbuilt tool to look at it's network connection. It shows that about every 5 secs, ping spikes. There might be other stuff happening, like some loss, but I can't say for sure. This translates into choppy gameplay which is unbearable for online FPS. If you look at the attached image, you see that the spikes go to 128 ms. I normally run 44 ms.

This symptom does not start immediately and I haven't been able to check how long it takes to start. It does go away if I close firefox down.

I tried to: - remove all addons - close tabs until only home/empty tab was left - removing/reinstalling firefox.

Nothing really worked.

I am running the latest version of Windows 10 (1803) with the latest version of Firefox 63.0.3. All 64bit.

Beginning with Firefox 58, I haven't been able to use it for more than 5 minutes as it constantly crashes. There is no crash report to speak of, only the 'Restore tabs' option.

I tried all the guides I could find: - restarted with all addons disabled - fully wiped any installations and downloaded a new version - I am running Mac OS Mojave 10.14.1 (18B75) (lastest version) - about:crashes does not list any reports

I am forced to use other browsers because of these crashes, which is unfortunate. I also use Firefox on Windows 10 and I've never seen it crash. I also recall it crashing on High Sierra as well, so the Mojave upgrade wasn't the source.

Can anyone help me out with debugging this issue as I simply cannot solve it by myself and I've exhausted all the official guides as well as other topics.

Thank you.

I noticed a few months back that Firefox quantum 65.0.2 (64 bit) uploads are extremely slow. A 186kb image that is uploaded instantly in Chrome or Firefox developer edition (65.0b11 64 bit) takes about 30-45 seconds in quantum, a 900kb image jumps to 14% when I hit upload, then super slowly climbs up by 2%-4% at a time, finally finishing the upload 3 minutes later, and by the time the upload finishes the google captcha I entered has expired and it tells me to retry the upload. The same 900kb image uploads in 2 seconds on chrome and firefox dev. Also some websites like twitch.tv are super slow to load, not even a video stream, the homepage takes about 20 seconds to load, then another 30 seconds for the video to start playing, while the site loads and starts playing the homepage video within a few seconds on chrome and firefox dev. I've tried everything, launching firefox in safe mode, reinstalling firefox and trying with no plugins, switching between system proxy settings and no proxy. Is there anything else I can try? Super annoying having to launch chrome every time I need to upload something.

Thanks

Ever since I upgraded to Firefox Quantum this has happened: Whenever i'm on a YouTube page where the sidebar (where you see Subcriptions, Saved/Your Playlists, etc.) it always makes Firefox Quantum freeze and say "A webpage is slowing down your browser."

Clicking "Wait" does nothing and just makes the error pop up again after a few seconds. I have to click "Stop It" to make it fully load. This doesn't seem to happen on a video page as, for me, the sidebar isn't shown when I'm on a video page.

Is there any reason it is doing this? YouTube worked fine before I upgraded to Quantum, and now it seems like YouTube doesn't want to work with Quantum correctly?

I'm running Windows 7 Home Premium SP1 64-bit.
