Hi, I hope someone can help! I've tried everything.

I’m using a desktop; Dell; newer. Windows 10; 1903; plenty of speed and space left. No viruses, etc.; have done many scans (malwarebytes, adware, etc.)

For whatever reason (I think I incorrectly shut down Firefox and/or my computer, and that was the beginning of the problem), Firefox is causing lot of issues.

Won’t open or close. followed all the advice on this site.

Found out on this site to try ending Firefox in task manager; when that didn’t work; went in to and deleted parent.lock from the profile.

Then rebooted the computer; still wouldn’t open (or did once, but then had the same problem?) Tried shutting off the computer and restarting rather than rebooting many times during all this process as well.

I followed what someone said about adding the word OLD after places.sqlite. So in the original profile folder I have:

    places.sqliteOLD
    places.sqlite-shmOLD
    places.sqlite-walOLD

that didn’t help things. Then someone said to add OLD to ‘prefs.js’

So I have:

      prefs.jsOLD
      prefs-1jsOLD
      prefs-2.jsOLD
      prefs-3.jsOLD
                  Etc….up to # 9; I have 9 of them

That didn’t help.

I then saved that original profile to the desktop. Uninstalled Firefox; and reinstalled it.

If you go into profile folder, it shows the original profile(‘default’) and a new one I guess it creates when you reinstall Firefox? (called ’default-release’).

I tried opening etc. with that new ‘default-release’ profile. Same issues. Again I went into task manager, to end process (sometimes works for some of the instances; but usually not all?); deleted parent.lock again. Rebooted.

Then I created a brand new profile (without going into Firefox; but following some instructions on how to create a new profile without Firefox being open).

I opened Firefox with that brand new profile (it asks me which of the 3 profiles I want to use when I went to open Firefox). I opened tabs, used it, etc. works ok; …..

BUT it won’t close or reopen! So same issues with the brand new profile!

The ‘default-release’ profile and the brand new one I created were never changed or touched; never added the word OLD to anything in there; made no changes.

So Firefox wouldn’t close; so I had to do all of the above again (try to end task in task manager; delete parent.lock, and reboot).

So now I’m at my wits end!!!

I can’t find anything left to try.  : (

I hope someone can help!

Thanks!

It crashes whenever I try to look at my Facebook updates (scrolling down), happened only recently when I updated to FireFox 38

Yes, ever since the update to Firefox 29.0 the other day, I often get the "already running but not responding" message on trying to start the program, and thus have either to kill the service in task manager or reboot. I've already changed the properties of the profile to uncheck read only and already disabled an add-on (tab mix plus). My other add-ons are Better Privacy, AdBlock Plus, and Fire FTP, and darned if I am going to go without any of them. I can't help thinking there's just a serious bug in this new rollout. It's especially frustrating as I've used and supported Firefox and Thunderbird for so long now. I feel I'm being chased to Chrome! (I run Windows Vista, no firewall. The other suggested fix, deleting the lock file, is recommended, I see, only if the message persists after reboot, obviously not my issue.)

Hello, My Thunderbird 32bit installation upon Microsoft 10 64bit installation just upgraded itself to 7.2.2 and produced a severe performance problem after initial startup. The response to attempts to navigate through the folders is very slow. The Microsoft Task Manager shows that Thunderbird is constantly busy 15-20% Cpu usage and flashes of 'Not responding' although the program has nothing to download.

There 4 accounts configured (3 imap and one pop3) and there are lots of folders with stored emails. There is one Lightening calendar configured.

The performance issue continues for about 10 minutes and then disappears so the system becomes as responsive as it was before the upgrade i.e. instantaneous.

I cannot tell you what release I was on before the upgrade. Any suggestions Patrick

On Saturday July 4th, I downloaded Mozilla Firefox 39 and finally got it working after finding out that Norton firewall was keeping me from accessing the internet. Now a new problem has arisen. The websites Facebook and Publisher's Clearing House is causing Firefox to crash. Even this page that I'm typing on caused Firefox to crash. I'm using my phone to type in what is happening. Any suggestions folks?

Since two weeks or so, whenever I'm (also) running Firefox 53, all over sudden my whole pc freezes: nothing works anymore, no mouse, no task manager, nothing. FF does not create a crash report (doesn't get a chance to do so) All I can do is a hard reset. This does NOT happen when I'm not using FF. (Sometimes I get a warning that Firefox has stopped, but then it keeps running, so probably one of extensions or add-ons has failed.) I have a stand alone, always fully updates Windows 7 Pro SP1 x64 pc. SFC /scannow was ok, CHKDSK had to repair errors in the volume bitmap, and memtest86+/8 passes came clean. I cleaned up FF and am now only running one extension.

There can be three causes: 1. Firefox 53 2. Extension(s) 3. Windows (latest updates) 4. Other/unknown

I generated a memory report, which is abracadabra to me, but I it points out what's wrong and someone can explain what to do. But how can I post the memory-report.json.txt?

I use Firefox on a Mac (Snow Leopard) and I recently updated Firefox to version 18.0. After I updated, Firefox will freeze everytime I go on Facebook and I would have to force quit it. One thing I noticed is that it crashes when almost everything is loaded but the chat. Does anyone know how to fix this?

SO many issues with Firefox now! For one, it crashes quite a bit. I submit the crash report, and go from there. Keeps happening. But the main thing is this:

I go to "Options" and under "Privacy" it has "Never remember history" - I change it to "use custom settings for history", hit "ok" and then when I go back to it, it's back on "never remember history" already. What gives?

The issues I'm having right now is that I used to click on Print in my email (Yahoo) and pop-up blocker would stop it, but a dialog would pop up saying "try again", and I would hit that, and a separate window would open where I could print the email. Now, when I click on print, NOTHING happens. No box, no changes whatsoever. No pop-ups blocked, nothing at all. I mean, the button for "print" doesn't even react like I clicked on it. Nothing happens.

The other issue is that when there's a text box, if I start to type my email address, it suggests my email address. It never used to do this! I don't want this, either. How can I stop the suggesting of my email address. I don't want it to remember what I typed!

Another issue with Firefox is that when I click on the "menu" button in the top right, there's a question mark that says "open help menu" at the bottom. When I click on that, the help menu is EMPTY. I included a picture so you can see.

I've "reloaded Firefox", as well as downloaded another copy and actually reinstalled it. All these errors keep happening. How can I get them to stop or function correctly? What's causing them to work all wonky?

Hi, after updating to Java 7 update 10 Java stopped working. Plug in checker indicates Java Deployment Toolkit 7.0.100.18 is installed correctly, but Java test page says plugin needed and Java Runtime Environment 1.7 u10 is available. Install fails. Uninstalled Java and tried manual install (including as administrator) but no resolution. All old Java versions have been uninstalled. Thank you for your time.

Here is what I have tried so far to correct this problem: I have uninstalled and reinstalled FF. Updated my pc's graphic's driver. Started FF in safe mode. All plug-in's are up-to-date.

I am running Win 7 (64-bit). Please help!

Both FireFox and Google Chrome (but not Internet Explorer) have been showing black diamonds with question marks in them for some time. It's not an encoding issue, as changing character encoding doesn't work. I don't know what caused it, as it all of a sudden started out of the blue. My network.http. in about:config are all default. I've tried scanning for malware, including in safe mode with the internet disconnected. Nothing has made a difference. Please help me, as this problem is incredibly hard to Google and I have no idea what to do.

Before the update everything was working fine, but yesterday after the update I noticed that whenever I open a page and after that I hit back button, it doesn't reload the page like before. It's annoying, because I use forum and sometimes is confusing when I open a thread and after that it still says that "new thing", the only way to remove it is to reload the page from the refresh button.

I have a Dell Windows 7 Professional 64-bit machine. Firefox keeps crashing. "Sorry. Firefox had to close. We'll try to restore your page." (Not exact message.) I have screen shots of the details, which are always the same. The first two lines of the details are: AdapterDeviceID: 0x2e22 AdapterVendorID: 0x8086 With the help of technicians I have tried the following fixes, none of which work: Checked my video drivers. Updated my Intel drivers. Fiddled with the compatibility window. Tried Windows 7 and Windows XP. Checked and unchecked various items. Clicked on Mozilla's "troubleshoot compatibility," which made some changes. I am not computer-savvy. However, anyone who cares to respond can make your suggestions as technical as you need to; I'll share them with my technician.
