Hello,

When I close Firefox after the last update (current installed version: 112.0 x64 Windows 10), Firefox creates almost 200 processes (in the latest case 177), each using from 17 MB to 65 MB RAM (except one that is using over 200 MB - I guess the main one) using 100% CPU for about half a minute, and in that my PC is unusable - everything hangs. It takes a bit more time to close all of them.

Any ideas what could be wrong and how to fix it?

Thank you.

Hey folks,

i am facing issue with high CPU usage on firefox in completely different process other as visible in task manager than my actual process for firefox. is there something wrong with firefox or my system.

This separate process uses more than 60% of my CPU (AMD Ryzen 5 4600). If I close that process in the task manager nothing happens to my current firefox process and i can use firefox normally.

But everytime this separate process starts my system fans ramp up and CPU temps peaks to 70 degrees celsius. and i have to end that process to make it run normally. Thats a quite annoying process to do every time.

I am able to recreate this separate process by:

  1. 1. Plug my system for charging
  2. 2. I was working offline and connect to internet

both the times the separate process automatically starts and uses very high amount of CPU. I even left my system for 2 hours to keep that process running and complete whatever it was doing. but nothing happend. It continued to run for 2 hours also.

Please find a solution for this. I have already tried solutions provided in the forum:

  • Restarting firefox
  • Refreshing Firefox
  • Enabling hardware accleration
  • Clearing some user profile data
  • Completely uninstalling firefox and deleting the residual files then reinstalling etc.

but nothing worked.

YouTube videos on Firefox getting slower and jerky. After refreshing Firefox (Settings -> Help -> More troubleshooting information -> Refresh Firefox), it is OK, but only for a short while. Then the problem starts again. Same YouTube videos are running fine with Chrome at the same time.

Running Windows 11 Pro (Clean windows setup not long ago and the issue was there from the beginning.) German Language Firefox 116.0.2 Build ID 20230805021307 Intel CPU i7-1360P, 16 GB RAM, 1TB M.2 SSD

Would really appreciate a solution for the issue because I really like Firefox!

Hello,

I've spent several hours today trying to fix FireFox slow start up on my system. After start up (about 2 full minutes), everything works normally. The hardware is an ASUS A88xm-A MB, A10-6800K processor, 16G DDR3, runs OS and programs off an SSD. I worked through all the slow startup suggestions, ran memtest (0 Errors, 1 Pass), disabled all add ons, (even the OpenH264 video codec (I use the onboard HDMI, no graphics card)), turned off hardware acceleration, etc. When starting in troubleshoot mode, less than 30 seconds, (acceptable), but I really don't know where to begin with the "More Troubleshooting Information" when I look at the table generated by it. There have been no other problems to date with the system, and the long start-up time began with 20.04 Ubuntu (about a minute), then got worse when I upgraded to 22.04 to try to solve THAT problem. Currently running FF 104.0, and the update page says wait for a distro update if that is how it was installed. I believe 104.0 is the latest Linux 64b version though. All updates to the system are done as soon as I'm notified of them. there have been none since the upgrade a few days ago.

Any suggestions? Gotta get some sleep now... TIA, Dave

This has been happening to me with recent updates of Firefox, and I am very close to dumping a browser that I have used for years because of it. I go to load pages and it just sits there and spins and spins. In the time I take to open another browser like Chrome and copy and paste the exact same links into Chrome, where the download of the web page is practically instant. I go back to Firefox and it is still spinning and it is just ridiculous. I have no clue what would be causing this. After it finally loads a page, it seems fine on subsequent loads of pages.

Hail:

System Software: Win11Ent_x64 v22H2 (b: 22621.2283) MFF v18.5.0.0

No matter what I try, my MFF keeps crashing at startup. For some reason, it tries to open 2 pages the windows at the same time, which is illogical. I deleted firstly my: sessionstore.jsonlz4 logins.json to no avail.

Then I tried to open MFF through elevated CMD with the command: C:\Program Files\Mozilla Firefox\firefox.exe -safe-mode Again, 2 windows pop crashing immediately.

I do not understand why all of the sudden, it tries to open 2 different instances at once. This makes no sense. I am out of ideas, having tried many an option found on Google, but which none give me a solution.

If anyone has an idea, I would be quite darn thankful. This MSEdge crap that I need to use now is not quite my thing.

Thank you. Ke'Ylan

When downloading files, Firefox no longer remembers the directory path the file was previously saved to on a per-URL basis.

Previous Firefox behavior: #1. download file from website "aaaa.com" to a folder on your computer, "user/frank/companies/aaaa/". #2. download file from website "bbbb.com" to a folder on your computer, "user/frank/companies/bbbb/". #3. Now, go back to the website "aaaa.com" and attempt to download another file. Firefox used to present the previously used directory for this particular URL, in this case, "user/frank/companies/aaaa/" - but instead, now it presents the most recently used directory path, which was "user/frank/companies/bbbb/".

This issue has appeared before and the advice to fix it was to go about:config, search for browser.download.lastDir.savePerSite and make sure it is set at TRUE. I have done this, but the issue remains: Firefox no longer remembers saved file directory paths on a per-URL basis.

MacOS 11.6.6 (Big Sur); Latest Firefox (103.0.2) Attempts to fix: Safe Mode - issue still present; Refresh Firefox - issue still present

Is there any advice on how to fix this problem? - Thxs.

Upgraded to version 101.0 after getting the pop-up prompt and now every site I visit is taking at least twice as long to load and display compared to yesterday. (Even this support site!)

It has to be something in this release and not my connection, because:

  • My mail client is completely unaffected and is behaving normally.
  • I tried accessing the sites that were loading/displaying slowest using Opera, and they loaded as fast as they had in Firefox previously.
  • Nothing else that uses my internet connection is working any differently than yesterday.

I also cleared the Firefox cache. No improvement.

It's not my add-ons because the only one I have installed is uBlock, which is recommended in various help articles here at the support site.

Nothing in the knowledge base has proven helpful.

Is anyone else having this problem? Is there some tweak I need to make in about:config to fix this? Or is this another case of "wait until the next release", yet again???

I wondered several times why firefox recovers old tabs when it chrashed. now i see that in my profile folder/sessionstore-backups the file recovery.jsonlz4 is some days old (while i was using firefox in the meantime very often) and does not update frequently as requested by about:config browser.sessionstore.interval = 15000 (15s). - this folder or the files are not locked. i can delete/rename them, they are not re-created - there is no file sessionstore.* in the main folder of firefox profile while running firefox - i am using 102.4.0esr (32-Bit) on a company PC (could there be any restrictions?) - the file previous.jsonlz4 seems to be created correctly when firefox is closed normal (which is not my usecase, i want to restore up to date tabs after crashes) - i am not using a private window

do you have any idea?

Hello everyone. Since installing Linux Mint in May 2023 I have been having this issue with Firefox.

Description of issue: When I switch between (or drag) tabs in a Firefox window, the whole window becomes unresponsive, with the last tab I was switching from still in front. Often the contents of the window start to flash (disappear and reappear, leaving a black backgground) every 2 seconds. I can drag the window around, scroll, minimize it, but it is impossible to give any input in any tab. The only action somewhat possible to do inside the window is bring other tabs in front, it is still quite hard for the input to register, and if it does, it takes 10+ seconds. The issue goes away if I close the specific Firefox window, or if I manage to select and drag one tab out of the frozen window into its own new window. Then everything works as intended, like nothing ever happened.

I can reliably cause the freeze-up in a short time by holding CTRL+TAB and drag one tab to change the order while firefox cycles through the tabs in the open window.

While the window is frozen, the rest of the desktop is responsive as normal, even other Firefox windows. If I try to interact with the frozen window I can rarely see spikes of CPU usage. RAM stays at normal usage levels, far from being full.

What I have tried so far that has had no effect on the appearance of the issue:

1) Disabling all extensions i have

2) Run in troubleshooting mode

2) "Create a new places database" as suggested [https://support.mozilla.org/en-US/kb/firefox-hangs-or-not-responding#w_fi...]

3) Disabled hardware acceleration

4) Creaing a new firefox user profile

5) Use "Refresh Firefox" from the troubleshooting page

6) Use the Flatpak version of firefox

7) Reinstall firefox

Here is my system information

Hi everyone,

lately I started experiencing a font-family-related issue. On certain websites the font-families/styles look broken. I tried troubleshooting the issue by myself without any luck. What I did so far was reset my Windows fonts to default, reinstall Firefox and look what font-families are loaded through the Inspect tool. If I opened the same web page in Chrome the font looks OK. Two websites the issue is most visible at - support.fiverr.com and gmail.com when someone replies to my e-mail.

I love how the new tab page clearly states "Never fear losing a closed tab again.", and then when a window disappears it is followed by zero history to recover it. I have not restarted Firefox, let alone my computer since the last time the window was seen (about half an hour ago). It's not in my Alt+Tab tray hiding. I don't even remember closing the tab--though it's possible my keyboard double pressed when I was closing another window. (It's old and has a tendency to double hit keys). But now I have lost a window with at least 20 tabs open--mostly things i had yet to deal with and don't remember the URL to get back to it.

What use is my history and ability to reopen accidentally closed windows if everything just disappears from it within half an hour after the window could've been closed?

I would prefer to keep most of my browsing on Firefox, but I can't constitute that if I'm going to lose months worth of saved tabs randomly.

"The WidevineCdm plugin has crashed" - unable to use any streaming service.

Whenever I attempt to watch something on any streaming service, I get an error message from the streaming service and a note from Firefox saying "The WidevineCdm plugin has crashed." I have tried to solve this problem a number of ways, but have unable to find a solution.

My best guess is the problem is due to the most recent WidevineCdm update, as in the plugins settings the most recent update for the plugin was on 10/21/23, which is shortly before I first noticed the problem. I did test out various streaming platforms on other computer browsers (Chrome and Microsoft Edge) — they gave the same website errors as I got on Firefox, but those browsers did not indicate the cause or suggest which plugin failed. I additionally tested out desktop apps for some of the streaming platforms; they work fine without any issues, but unfortunately the main streaming platform I use doesn't have a desktop app and only works in browser.

My computer is a Lenovo Yoga 9i, it's running Windows 11, and everything is up-to-date.

The methods I have tried to fix this issue with, to no avail: - submitted crash reports - toggling the "play DRM restricted content" options in Firefox, and toggling whether or not the WidevineCdm was activated, closing the browser between each toggle of options - clearing Firefox's cache - running Firefox in troubleshooting mode to make sure it wasn't a different extension interfering with it - tried running Firefox in compatibility mode - tried to find support from the people who made WidevineCdm, but apparently they don't do end-user support - deleting the WidevineCdm manually from the program files for Firefox and Chrome (since Firefox says the plugin is from Google), and then reinstalling it via the chrome components page. This briefly lead to the message on the plugin page that WidevinceCdm would "begin installing shortly." It seemed frozen like that for a good while, but then I tried clicking the "check for updates" and that message disappeared, and it went back to crashing when I tried using a streaming service. - uninstalling both Chrome and Firefox, restarting the computer, then reinstalling both browsers

As far as I can tell, the plugin comes automatically installed in the browser, and there isn't an alternate plugin for decrypting DRM-restricted content. If there's a way to set the WidevineCdm to a previous version before the update that's crashing it, I haven't found it, but I am no expert in computers or coding, and my guess about it being caused by the recent update could be wrong too.

I'm at my wit's end here, any help fixing this problem is greatly appreciated.

Just recently, I've been having problems with websites run by Cloudflare. Whenever I attempt to access ANY website that is operated by Cloudflare, I'm often presented with a blank page, or a Firefox error message. Sometimes I'm even presented with the DDoS protection error, even though my computer is clean having being scanned by Kaspersky and Malware Bytes.

I reiterate this and say that it's only Cloudflare sites that are causing problems. Very occasionally they will work for up to an hour or so but most of the time it is error messages or blank pages. Interestingly, other web servers such as Amazon, OVH SAS and Akamai all run with no problems so I wonder what is Cloudflare's problem? Is this something to do with my browser or the web hosting services?

I got a notice that Firefox (and Thunderbird) were updated this morning. Took me an HOUR to find out how to make the miniscule font in my inbox larger. So.. suddenly, new problem.

When I click the Firefox icon to launch the browser, and reopen my tabs, It opens for a millisecond, then closes faster than I can try to read if there is an error. When I click it AGAIN, all my tabs are GONE and I have to search for them manually, which is a royal pain.

Why is this happening? How can I stop it from happening? This is annoying as hell.

Hi, I just replaced my SSD (Samsung 960EVO m.2 250Gb) for a larger/faster SSD (Samsung 980 m.2 1Tb) . I'm on Windows 10 and have 32Mb Ram. Firefox is now very slow on some websites (not all).

This example is typical and has occured on multiple sites. To test and compare, I copied the URL, created a new tab in Firefox, then Paste and Go. I timed this 3 times and each time was 30 seconds. I Pasted the same into Chrome and Edge and each time it was instant. https://savingschampion.co.uk/best-buys/personal/easy-access-accounts

On my previous SSD, there was never an issue of any lag on any site.

BBC.co.uk/news is fine, as are several other sites. Does anyone have any idea what's happening? This is making Firefox unworkable for me, so unless I can fix the issue, I will have to move permanently to Chrome or Edge. That would be a shame after many years with Firefox.

Thank you in advance.
