hi i have a .... to me ... big problem.

firefox will not even start and stay up. i can hardly even get the crash message up and the widow goes away.

firefox just crashes before its had a chance. downloaded new and same thing happens. a crash report comes up but i can't get the report written before its gone.

installed new version of mozilla. still persists

so i followed the prompts form here, "You should copy the Report IDs for submitted crash reports (they start with bp-) to your support question in the Community Support forum."

and i get this, Crash ID: bp-74f92cba-0ebf-43ba-a7bc-2a1871171126

can you help me pls. thnx brian

When I try to set Firefox as my default browser in Windows 8, the options menu goes to the Set Associations menu and won't set it as the default browser. In the instructions on your website for the alternate way to set it it only gives directions for Windows 7, Vista and XP not Windows 8. This is most annoying. I have tried reinstalling Firefox but that didn't work.

I finally uninstalled Chrome and put in Firefox. Haven't used it in years.

On my screen most pages are "wide" -- so a horizontal scroll bar appears at the bottom of the page, and to see the very right hand side of the page, I have to scroll over.

I have tried the CTRL and - but all that does is shrink the text on the page. It doesn't make everything actually fit on the page horizontally. See the uploaded images of a question I found on this topic on this forum. Even though I've shrunk the font size down in the second one, I still see the horizontal scroll bar at the bottom. Even if I shrink it all the way to the minimum (which results in a tiny font I can't see), some of the page appears off-screen and has to be scrolled over to be seen.

I have tried for an hour to fix this and there doesn't seem to be any way. HELP!

Task manager shows Firefox loaded as a service but has threads waiting to complete. There is no application shown in Task Manager (which seems reasonable as Firefox has not loaded). There are no error messages. The " microsoft spinning circle " goes for a few seconds and then dissappears as if the program has loaded. Happens only after 2nd & subsequent loads after reboot. Firefox appears to work first time after reboot. This has only happened after upgrade to 42. Clean install makes no difference. Chrome works OK Has worked fine up until update 42. Already tried doing a clean install with the Inform Mozilla box cleared. Perhaps Firefox has started using a port that is blocked by the virus scanner? I get no logging for the virus scanner showing anything blocked. A full virus scan reveals nothing. Operating system is Windows 10 (64 bit)

I then googled and found that you could remove profiles.ini and ~/.cache/mozilla/. I've removed both of these as well as reinstalling Firefox multiple times.

But it still show the error message. It even "spread" to Thunderbird.

Hi All, I have only recently installed Firefox for a specific purpose, have no plugins installed, just the basic program with about 3 bookmarks, that's it. Was all working OK until yesterday when it just wont boot. I have tried everything I can think of, so far:

Have tried removing (using app cleaner) and re installing - No joy

Tried going to profile manager through terminal - deleted and created profiles but still no joy

Tried deleting app again with app cleaner and reinstalling previous version - no go

Tried starting app in safe mode (shift key) - no go.

Looking for suggestions as I need to use Firefox for just 1 old website that seems to not work on anything else!

I'm running a Macbook pro Early 2015, Mojave 10.14.6

Alright, I use Firefox like normal, but sometime today it stopped working, I get "Your Firefox profile cannot be loaded. It may be missing or inaccessible" error, I looked it up using safari, followed every possible interpretation of the instructions to no avail, I deleted the profiles folder and file, in both cache, and application support, on both my user folder and global HDD folder, no fix whatsoever, I don't know why this isn't working (yes I checked the hidden files, I searched my entire HDD and found no results for anything remotely named "Profile"/"Profiles" and I don't know what else to say.

I have checked: Application support (on every user) & Cache (on every user)

I don't know what's up, I also reinstalled Firefox after deleting everything related to it and I just don't know.

My firefox browser will not open, so I can not try most of the solutions recommended. I do not want to lose stored information such as bookmarks and pass codes so would unstalling and reinstalling cause me to lose that information? I need to speak to a person to help with this, but do not know how to go about it. Should I be contacting Norton or Mozilla?

I noticed that firefox stays in memory after I close it. In fact, If I open and close firefox 10 times, ten processes are shown in memory, each consuming around 100Mb.

I'm using Windows 7 in my corporate computer and I have been using Firefox 65.0.1 x64. I've tried to use it in safe mode (no add-ons) and problem persisted. I uninstalled it, deleted all Mozilla data in AppData and ProgramData and reinstalled it fresh. The problem persisted.

Then I installed the 32-bit version of Firefox and the problem is no more. Is it a bug that has to be fixed or some setting that shoudn't be enabled?

Thank you.

Since version 42 it's not showing any website properly. Not even in Safe Mode and even after resetting everything countless times. Even after uninstalling and re-installing it's same. Uninstalled and re-installed version 43; with default settings and all issues are still there.

As you can see in images, there are no problem with internet connection. Everything else is working just fine.

Hello, I've been trying to install the latest firefox on my pc running windows 7 home premium, 64bit. I have cleaned the pc with ccleaner, run mutiple scans with malwarebytes and commodo antivirus, uninstalled old firefox programs and deleted as many junk files and programs that I could find. I have also tried to download with Expolorer rather than Chrome ...All to no avail. The following message details accompany the window which displays.. "firefox has stopped working", and firefox never opens to get to a "safe mode". I have used firefox up until a few weeks ago when an upgrade attempt failed. I would really like to use firefox again, but can't seem to resolve this issue. Your help would be much appreciated. Joe

I have to use Windows 10 (Home v:1703).

I'd like Firefox to be my default browser, but it's not listed in 'Choose an App'.

There's just Microsoft Edge listed, along with Internet Explorer, and an option to choose an app from the shop.

Microsoft Edge is also presumptuously shown as the default app to start with.


If Firefox isn't listed, how can I set it to be my default browser - or, isn't this 'allowed' in Windows 10 ?

I just upgraded to Firefox 77, x64, Windows 10 2004.

Firefox 76 already broke LockWise - https://support.mozilla.org/en-US/questions/1287008

Now Firefox 77 breaks 99% of all websites. (See attached screenshot.) www.example.com www.google.com www.wikipedia.org etc

Somehow, support.mozilla.org works, UNTIL I try to log in.

I've tried incognito mode, safe mode, etc. When I change charset of the page, the text displays differently, but it's still a useless mishmash.

--- BUT --- when I open developer tools, click the HTML request and click the Response tab, the HTML renders correctly there.
