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

......so I have been forced to make Chrome my default browser ( I prefer FF) as I like to use split screen with other genealogical websites. I caled MY Heritage but they couldn't help. Any suggestions?

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?

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'm using adobe flash on manual activation and it's causing Firefox to hang indefinitely. Disabling Hardware Accel cause Firefox to be unusable. Please help. I have no idea what went wrong.

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.

Since the last update Firefox doesn't work properly anymore, after one minute it stalls. I did fresh up, so all my adjustments are gone. But it still stalls. I have to forceclose firefox. And can start it again. as soon as I play a youtube film it stalls again, or google agenda, I allowed pop-ups, so at least it got started, but after doeing 3 things in it firefox stalls. Can I put it back on the version before?

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.

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?

In recent weeks on 2 different PC'a (both W10 64bit) - Firefox has become slow to start up.

Previously click on start bar - seconds later FF would open followed by a delay Google then open as home page.

Now click on start bar - nothing .... can be 10sec or more before anything starts ...... often you even think that maybe you missed the button ..... this is very noticeable recent change - has an update caused this ..... my builds are up to date.

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.

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 was using my computer a couple of days ago with no issues, shutdown the computer for the night, then the next day there is a delay for the context menu to show up after right clicking in both Firefox and Thunderbird.

Aside from installing a few updates I have not made any changes to the computer since the day before & I have no issue with context menus in other browsers or the OS.

The hardware a Dell Optiplex 790 with an i5-2400 quad core, 12 Gb ram running Ubuntu 17.04 64bit.

The symptoms:

- The right click context menu takes approx 5 to 8 sec to show up. - Drop down menus on web pages & in settings behave the same. - Occasionally the FF window will darken for a second or two then return to normal. - When an option on the context menu is clicked it is taking about 3 sec to go through.

Fixes tried:

- New Profile. - Safe Mode. - Disabling Hardware Acceleration. - Complete removal of FF & TB as well as their folders. - Downgrading to FF version 50. - Checked on another computer (this one is running Lubuntu, & does not show the issue).

Does anyone have any ideas?

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

Please help.

hey guys, i wasnt sure where i could put this info, i have discovered some info regarding the "FLASH PLAYER PLUGIN." that doesnt seem to be documented on any kb article or support thread, so hopefully one of you will be able to help getting this submitted. obviously this wont fix everyone's problem, but it should be included.

THE PROBLEM::

Flash Player Hanging or Crashing (unable to watch flash/video content) Script has become unresponsive error message when trying to view flash/video content

THE SOLUTION:

a possible cause to this problem is that you have lost permissions to the file directory where flash is actually stored. without these permissions you will be unable to properly utilize the flash plugin on firefox.

to fix the problem we will need to update the security settings on the flash directory.

for 32 bit machines: C:\Windows\system32\Macromed\Flash

for 64 bit machines: C:\Windows\SysWOW64\Macromed\Flash

navigate to the \Macromed\ folder and right click on the flash folder and select properties. click on the security tab at the top of this box then on the advanced button at the bottom of this box. after navigating to this screen, you will need to click change permissions. first make sure there is no deny statement which is denying access to this folder, if one exists, remove it. second make sure that the name "Everyone" has the abilty to read and execute, to do this: click on everyone, then edit. next, select: apply any changes to: "This folder, subfolders, and files." this is at the top of the edit box. after you click ok to the changes you made, you will need to enable the option: "Replace all child object permissions with inheritable permissions from this object." now click the apply button, then ok button. now check to see if firefox is working.

if you find that you are unable to change these permissions, then you lost access to the parent folders as well and they are replacing child object permissions. you will need to apply the solution above to the parent folder that is overriding the permissions. this will either be: \system32\ or \SysWOW64\ depending on your machine or possibly even the \Windows\ folder.

If you find that these parent folders indeed had their permissions lost, then you have likely acquired some malware. You should download Malwarebytes Anti-Malware and do an update and full scan.
