Hello!

To ensure you are making a proper "clean" install follow these steps:

Certain Firefox problems can be solved by performing a Clean reinstall. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:

Note: You might want to print these steps or view them in another browser.

1. Download the latest Desktop version of Firefox from mozilla.org (or choose the download for your operating system and language from this page) and save the setup file to your computer.
2. After the download finishes, close all Firefox windows (or open the Firefox menu and click the close button ).
3. Delete the Firefox installation folder, which is located in one of these locations, by default:
   • Windows:
     • C:\Program Files\Mozilla Firefox
     • C:\Program Files (x86)\Mozilla Firefox
   • Mac: Delete Firefox from the Applications folder.
   • Linux: If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see Install Firefox on Linux. If you downloaded and installed the binary package from the Firefox download page, simply remove the folder firefox in your home directory.
4. Now, go ahead and reinstall Firefox:
   1. Double-click the downloaded installation file and go through the steps of the installation wizard.
   2. Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.

More information about reinstalling Firefox can be found here.

WARNING: Do not use a third party uninstaller as part of this process. Doing so could permanently delete your Firefox profile data, including but not limited to, extensions, cache, cookies, bookmarks, personal settings and saved passwords. These cannot be easily recovered unless they have been backed up to an external device! See Back up and restore information in Firefox profiles.

Please report back to say if this helped you!

Thank you.

Have already done that, numerous times... Does NOT work

this is what i get from the mozilla bug reporter: BuildID: 20150513174244 CrashTime: 1432640265 EMCheckCompatibility: true Email: FramePoisonBase: 7ffffffff0dea000 FramePoisonSize: 4096 InstallTime: 1432052826 ProductID: {ec8030f7-c20a-464f-9b0e-13a3a9e97384} ProductName: Firefox ReleaseChannel: release SecondsSinceLastCrash: 948 StartupTime: 1432640265 Theme: classic/1.0 Throttleable: 1 Vendor: Mozilla Version: 38.0.1 useragent_locale: en-US This report also contains technical information about the state of the application when it crashed.

The Crash report is several pages of information we need to see.

In the address bar, type about:crashes<enter>. Note: If any reports do not have BP in front of the numbers/letters, click it and select Submit.

Using your mouse, mark the most resent 7 - 10 crash reports, and copy them. Now go to the reply box below and paste them in.

Thanks FredMcD... but the issue is that to do this, i'd have to be able to actually launch FIrefox... its a catch 22 I'm afraid: i can't launch it AT ALL, neither in Safe mode nor normally, under my profile or another... this is maddening.

If you can't open Firefox, see:

• http://kb.mozillazine.org/Mozilla_Crash_Reporter#Location_of_crash_reports
• http://kb.mozillazine.org/Mozilla_Crash_Reporter#Viewing_crash_reports

• https://developer.mozilla.org/How_to_get_a_stacktrace_for_a_bug_report

As an experiment, create a new, blank profile. Do Not make any changes. Use the new profile as is. Is there still a problem?

You can also use these steps to get the crash reports without opening firefox:

1. Click the Finder icon in the dock. On the menu bar, click the Go menu, hold down the option or alt key and select Library. A window will open containing your Library folder. Then open the "Application Support" folder, the "Firefox" folder, the "Crash Reports" folder and finally the "submitted" folder.
2. Open the 5 most recent files with a text editor and copy the IDs.
3. Paste each ID with bp- into the reply window on the forums.

@FredMcD @user293 thanks for the time and the help Deleting profile and creating a new one solved the issue!

Glad to help. Safe Surfing.
