Hello,

since months I have problem with automatic launch of Firefox on my computer, It's really insupportable. I'm ready to abandon firefox. I'm on windows 10 and I use Firefox 83. There is 3 different sessions on my computer and only one has the problem.... my session. Firefox launch a new windows always and regularely, when the computer start, and all the time during the use of my sessions. If i'm already on Firefox, a new windows open's.... If I close this one, few second after an other open's..... If I put this one on background, about 1 min after again an other open's. Like this always and indefinitevely. Whatever my use of the computer or the site to visit. Even when I don't use internet and use other software to work, Firefox starts up and goes in front of my software. If I let my session opened and I do nothings, after a certain time a lot of firefox windows are open. You can easily understand why I say that It's really insupportable... and this only with Firefox on my session.

My computer is protected with antivirus, and I did a full scan several time, I also tried with an other antivirus software. I used 2 softwares for detect malware... Nothing. I try to uninstall and reinstall Firefox, but the problem still the same after reinstall. I already set the "toolkit.winRegisterApplicationRestart" on "false" but firefox start alone again, again, again...

Does anyone has an idea of what is the problem and what I can do ?

Thanks.

Some time ago, firefox stopped launching. I tried everything. I refreshed, reinstalled, clean reinstalled, reset windows, deleted possibly interfering programs, and clean reinstalled windows (that was for other problems). I am running windows 10 home build 10.0.19042 (currently the latest) on a omen HP laptop 15-dc0xxx. It is x64 bit device with a intel core i7 8 gen cpu and a nvidia 1050 ti mobile. It does not seem to be a hardware issue as a linux kernel that I have dual booting with windows 10 runs it like a champ.

    When launched the application load for a period of ~7 seconds and for a frame or two there is a small window with either nothing on it or a safe mode window that goes away after a frame. When the problems started I closed firefox and reopened it a small bit later and the problems above happened. Windows safe mode will run firefox. Opera has very similar problems if that helps any. Google chrome, microsoft edge, microsoft internet explorer are all unaffected.

Hello, Firefox takes more than 30 seconds to load. Thunderbird is also slow. I've had this problem before at the end of last year. After a while it got better. But now I have to wait again. I scanned windows with various anti-virus and anti-malware programs. I have absolutely nothing. I only use Microsoft anti-virus. I have run many repair options on the net. I have also uninstalled and reinstalled Firefox. This long wait to load before I can use the software is really irritating. Internet Explorer starts within 3 to 5 seconds including the display of the first page. Best regards Otto Haldi

When opening any version after 89, Firefox opens then is unresponsive to any action. I have to force quit. I copied the crash report that is sent to Apple. It is a 500+ page Word document. The only solution is to reinstall v89.0.2 and it works fine. Then not allow automatic updates.

Any suggestion appreciated.

Thanks Ken

Firefox loading at logon and using 35% CPU

I have searched Windows Registry, Task Scheduler & Used Utilities to list and monitor Autoruns, Starups. I have no settings for this to happen.

It's getting close to time to DELETE FIREFOX since MSEDGE built on Chrome is Faster anyway!

I had tried everything. I have deactivated all FOUR of my plugins and started up Firefox again. I have uninstalled and reinstalled a fresh copy. I installed Firefox on an SSD even and it is still painfully slow. I have the same plugins and such on Chrome and that one opens up immediately. So I have been using Chrome a lot more lately because Firefox is opening slowly these days. Takes 15-20 seconds for Firefox to open every single time. I have deactivated each plugin one by one to see if they were causing the issue and sure enough, all of them were clean. Firefox still opens slowly.

On an unrelated note, I have been using Chrome a lot more lately also because some things on a webpage don't work on Firefox. I can't explain it. Like on the hickory farms website, I click on the Add To Cart button and it looks like it is being pressed, but nothing is added to the cart. This type of thing happens across the internet on many different sites. When I go to Chrome, everything works as it ought to. I have my settings set to Standard in Privacy and Security. I don't know where else I have to check and change things to get those buttons and other links and such to work.

Two days ago Firefox randomly started crashing on start up. I click on the icon and the window pops up for a moment and then closes immediately. I get no crash reports. I have tried reinstalling Firefox and deleting the cached data. I have tried running Firefox in Troubleshoot Mode and as an administrator. I have tried restarting my computer and updating my computer. I did not have any addons installed on Firefox and I was using the default theme. Nothing is working.

Any help you may have is greatly appreciated.

I have installed Firefox on my android phone now that I have installed Firefox browser on my desktop. Trouble is when I run it (on my phone) it very briefly flashes black & white blocks on screen and then makes my phone reboot. I have a Samsung galaxy S4 with android 9.0 (pie) installed. Is there anything I can do to make it work?

Every time I start up my PC I can find a firefox.exe process in the task manager that uses 40-50% of CPU and I have to terminate the process manually every time. Firefox is not enabled in my startup so I don't know what causes that process to show up and use that much of my CPU (note: an opened firefox browser with multiple tabs only uses around 5% of CPU just for reference)

Hello! I've been using Firefox for years now, and just recently set up a dual boot system with win10 and kubuntu. I've never had this problem with Firefox before, and it's only a problem on win10. When I open Firefox, there's only blank white where a page would normally be. Trying to right click brings up nothing. I can open the menu, but things like options, add-ons, customize, etc. all do absolutely nothing when I click on them. When I click on the icons of my extensions in the upper bar, the extension interface is empty as well. Nothing changes when I try to load a page--Using the search bar causes a spike in my otherwise flat ethernet usage (I dont have any other processes running that use it while im testing this, but just to cover my bases I can access the internet without any issues on discord or other online applications.) The search bar does retain what I searched. Rather than becoming about:blank, it just becomes, for example, "https://www.google.com/search?client=firefox-b-1-d&q=test" Other browsers work completely fine. I've tried doing a completely clean reinstall (deleting files in ProgramFiles, %appdata%, the Old Files folder that is created during an uninstall, and uninstalling using the apps and features menu.), using DISM to check for anything wrong in sys32, opening Firefox in safe mode, opening it as an administrator, disabling any firewall or antivirus i can find, and deleting my Firefox profiles. Nothing has changed anything at all. Please help! <3

Good day,

Everytime, since a few weeks, when I start a new session I have to accept cookies again with many websites. e.g. Google or De Telegraaf. Normally with the Telegraaf I have to log in just once, but since a few weeks I have to log in every time. In firefox settings I have "remember history" on.

When I open Firefox, I receive the following: Firefox can’t find the file at jar:file:///C:/Program Files/Mozilla Firefox/browser/omni.ja!/chrome/en-US/locale/branding/browserconfig.properties. I have seen the help that suggest I go to "about:config" and the browser.startup.homepage, which I have done. But the suggestion doesn't state what I should do once there. What do I do to the browser.startup.homepage?

Have tried just about everything (i think) as i have read in the other support posts. When i boot my computer and try firefox, it loads for a second and then crashes asking to send the crash report and to restore the tab. I click yes and it crashes again with the same window. Sometimes if i reboot it all of a sudden works. But literally everyday when i log on for the first time it crashes, then i reboot and sometimes it crashes, and then sometimes on the second reboot it just works somehow. I have tried installing earlier versions, refreshing firefox, starting in safe mode etc.

Here are a few of the crash IDs that were submitted successfully (others failed to submit). Thanks for your help.

I'm on a Mac, running the latest version of Firefox. Recently I've had some work to do that meant I wanted to keep multiple tabs open, so I changed my settings to 'restore previous session' so I'd get my tabs back when I turned my computer off/on.

For a few days all was going well, then Firefox crashed. I managed to get it back up again and change the setting so it wasn't trying to restore multiple tabs. But since then no luck, Firefox opens but I get the spinning wheel curser and Firefox shows as non-responsive, I have to force quit the app.

I've tried uninstalling it, still no luck. I'm writing this from Google Chrome.

Can anyone help? I much prefer Firefox, but it's currently unusable for me, and as the browser freezers I can't get into any of the settings etc.

I am using Firefox 94 on Debian Linux (details below). I've been a happy FF user for many years but, ever since I updated to Firefox 93, I've been facing an odd problem.

When I start FF (usually using my system launcher or the command line), the first window that opens will not allow me to open a new tab. Press the '+' button does nothing; trying to open links in a new tab does nothing; etc. Not only this, but it seems like there are other problems (e.g. my adblocker does not seem to be working in YouTube), but I can't confirm this.

When I open a new window from the menu, all functions work normally in the new window. But the original window continues to have these problems.

This isn't a major inconvenience, but it just seems like an odd bug.

One factor that might have something to do with this - I run FF inside Firejail. I start FF via a one line script:

`firejail /opt/firefox/firefox`

Maybe this has something to do with it?

Thanks so much to Mozilla for this wonderful piece of software, and to all of you for helping out with it!

My laptop set-up is practically identical to that of my PC, but the latter doesn't exhibit the same malfunction.

I've tried anything I could, including reinstalling the browser, removing all of my bookmarks (about 10,000) and addressing extensions (Decentraleyes, Default Bookmark Folder, Disable Tab Detach, Flagfox, I don't care about cookies, Keepa, Notifier for Gmail, Privacy Badger, To Google Translate, uBlock Origin, Undo Close Tab, Video DownloadHelper and Youtube's Annotations No More), but not even safe mode improved the situation in the least. Windows Defender also hasn't detected any malware and my web surfing habits are as safe as it gets.

The only deeper data I could gather is that the problem manifests with a progressive, rapid surge in CPU and RAM usage; the former, for example, is saturated to its total 16 GB in a matter of about 20 seconds.

My laptop is a Dell Inspiron 7586 with Windows 11 64 bit; Firefox version is the latest, 100.0, and, by the way, none of the recent updates has improved the situation.

Thanks to anyone who might come up with an educated guess!
