Firefox Support Forum

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.

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?

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 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!
