Hi,

Please note that you may have to re-trust the new Firefox in any installed security software. Firefox will not start.

Please also see this for a general overview.

The link was not helpful. It only really covers XP not windows 7. I did open a "run" box and cut and pasted the firefox exe file, but still nothing. So I was not able to delete any profiles or anything. It is not the security firewall ect either. I have spoken to 5 friends that have had this same issue and they are running windows 7. So I am surprised that so far only two people have said they have the same problem. If I know 5 people with this issue there must be a million others dealing with the same problem. I dislike chrome and googles privacy policies makes me want to avoid their browser and IE has always sucked - please help - I need my firefox back!

You can also try to start Firefox directly from the installed directory and also try right-clicking and Run as administrator.

Sad to say that neither worked. Run as an administrator or from the installed directory. I will have to go back to an earlier version of the operating system on my computer and make sure not to upgrade to 10 this time. Who knows what I will loose.

Quick question: when you uninstall why doesn't firefox delete all files? It just doesn't seem right. uninstall and re-install should fix almost every issue, but it doesn't because for some reason when we uninstall things software companies think we don't really mean it.

Thanks for the time and effort Vivek!

I think when uninstalling you may also have to choose (tick) to delete the preferences and other personal data like the bookmarks, stored passwords etc. to erase completely. If you are installing afresh, please try right-clicking on the file and Run as administrator to install. And when uninstalling, please also make sure choose to delete all data and also manually delete any Mozilla, Mozilla Firefox or Firefox from %appdata%, %localappdata% and %programfiles%. You can open a location by typing for eg. %appdata% in the Run box (Windows key + R). You may also have to check the VirtualStore folder in %localappdata%. Files in the VirtualStore can be problematic. I think a clean installation may help.

Profile Folder

Please note that using system restore would usually damage the Firefox installation.

Okay after the complete re-install I received this crash report when I tried to "launch as soon as the download was complete". This is the first time that I have even been offered to send a crash report. So I hope it helps, but for now the same symptoms - I click on the newly installed Mozilla shortcut and it just spins and does not open.

Well - Microsoft had a large update last night for the Windows 7 and I came in this morning wondering if the update would help my FireFox. I thought it might because a lot of stuff in this forum kept saying it was a security issue and these were security updates. Shazam! Firefox is now the my goto browser again. Very happy to have it back. Once again I did nothing this morning, but click on the icon after the big windows 7 update and we are back in business. Thanks everyone for your help!

Thank you very much for the helpful information.

Well - an interesting thing happened. The next day I came back to work and I clicked on Firefox and it auto-updated something. At least all a saw was a small pop-up box that said - "updating FireFox" - lasted about 30 seconds and did not ask me if I wanted to update. After that it stopped working again. So I gave up and ask my IT person for help and he knew a place where to get the old version of browser. So we did a complete uninstall and uploaded verison 9 and I set it to never update and now it works again. My friend with windows 7 did the same and now we both have it working again. Hate to not be able to update, but it is better than no FireFox at all.
