Many have reported issues using the 64bit Firefox. Install the 32bit version from; Download Firefox For All languages And Systems {web link}

I hope this works. I tried one thing where it was crashing & it didnt do so with the 32 bit. But when I tried to install the 32 bit using my Firefox browser, it crashed. So I had to make Chrome the default browser in order to install the 32 bit Firefox. Now I have remade Firefox the default browser. thanks.

Keep us posted.

ok. I have chatted with a number of persons from Mozilla. I dont know if they are volunteers or employees. They all gave me different suggestions, some of which took me a long time to do & none of their suggestions worked. Some just sent me to things on Mozilla Support which I either had done, did not look useful or didnt understand. None of them indicated like you that there were many problems with the 64 bit version. You were the first helpful person & had greater knowledge than any of the others. I would be interested if there is a reason for that. Dealing with Mozilla on problems is not easy because unlike most applications, you cannot call & talk to someone. Mozilla needs to improve its support process. thanks.

There are many systems that work with Firefox without a problem. Then there are users like you that have problems. All we can do is to try to find the source and find a way around or through it.

Everybody who has replied to your four threads here do not work for Mozilla.

No there are not really any problems with the Win64 Firefox compared to the 32-bit Firefox for Windows. There are certainly no problems with 64-bit Firefox for Mac OSX and Linux. The Win64 Firefox has existed for releases since Firefox 42.0 (November 3, 2015) and was in testing long before that so it is not new.

The vast majority, if not all free and opensource applications that you can download and use do not provide one on one support by say phone, chat, or email. Any that do provide one on one support are paid for things that you can buy in a store or activate downloaded applications. Mozilla does no have the resources to provide the call centres that would be needed to provided one on one support even if only just for desktop Firefox and not for all of their products especially since it would be for free.

Fred I am following your request to keep you posted. Firefox 32 bit has crashed once & I had trouble reopening & had to do it in safe mode. I submitted the crash report. But here it is. Please let me know how to prevent this from happening in the future. thanks.

For some reason, the entire message was not posted. What I said was that I was following your instructions to keep you posted. Firefox 32 bit has crashed once & a crash report was created. I submitted it. I had trouble reopening Firefox. When clicked on the icon in the taskbar, it closed Firefox. Then I was able to open it in Safe mode. I already submitted the report, but here it is. bp-74783164-cd36-4419-a271-7bb4a0191204 thanks. Jonathan Rose

It has crashed two more times & 3 times in a few hours. But now unlike before with the 64 bit it is creating crash reports. I have submitted both newreports. I have a lot of trouble reopening after the crash. I can only open by clicking on open in new window & opening in safe mode. Here they are the crash reports bp-1a116b86-7651-4b78-8c09-8211a0191204

Update your Realtime Soft programs and files. If the problem continues, disable them.

I dont know what Realtime Soft programs are. How do I find them on my computer? Firefox 32 bit is actually turning out to be worse than Firefox 64 bit

Could you please keep the discussion about Firefox crashing in this thread. Thanks.

I think that I now opened Firefox in Safe Mode & I have tested several of things that had been causing it crash & it didnt crash. Time will tell if it has completely eliminated the crashing problem.. If it doesn't I will contact you again. But I have some questions. First how can I tell whether it is running in Safe Mode? Why has this apparently solved the problem? Finally, do I lose any functionality or abilities of Firefox by running it in Safe Mode. thanks. Jonathan Rose

https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode

Safe Mode is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes). If the problem goes away, that tells us one thing. If it does not, that tells us something else.

It could be the work of one of your add-ons, or it could be Hardware Acceleration. How to disable Hardware Acceleration {web link}

Type about:addons<enter> in the address bar to open your Add-ons Manager. Hot key; <Control> (Mac=<Command>) <Shift> A)

In the Add-ons Manager, on the left, select Extensions. Disable a few add-ons, then Restart Firefox.

Some added toolbar and anti-virus add-ons are known to cause Firefox issues. Disable All Of them.

If the problem continues, disable some more (restarting FF). Continue until the problem is gone. After, you know what group is causing the issue. Re-enable the last group ONE AT A TIME (restarting FF) until the problem returns.

Once you think you found the problem, disable that and re-enable all the others, then restart again. Let us know who the suspect is, detective.

How do I know whether I am in Safe Mode? Do I lose any Firegox functions or abilities In Safe Mode? Should I go back to the regular & go through the steps outlined above? Please answer these questions. The only tool bars I have are Menu & Bookmarks, both of which I need. The only anti-virus I have is Window Security. I occasionally use the free version of Malbytes, but it is not running except when I do scans. Thank you.
