Solved: Mozilla Firefox not working on PC

Please can someone tell me how to get Mozilla Firefox to work on my computer?
If I uninstall it and do a new download it will work the first time but after I have closed it I cannot get it to come up on the screen again although it shows as in the Task Manager as being active
Other browsers will work, internet explorer, etc.
Windows firewall set to accept.
Windows edition 8.1 on a PC
Processor Intel(R) Core (TM) i3-3220 CPU @3.30GHz
Installed Memory 8.00 GB (3.47 GB usable)
System Type – 32-bit Operating System, x64-based processor

 

Try uninstalling it again type %appdata% into the run box then find and delete the mozilla folder and re-install this will give a new version of firefox with no previous settings.Just note if you take this action all previous passwords bookmarks and settings connected with firefox will be lost.

 

I have tried this and the result is the same but thanks for your information

 

The answer is quite simple, I am not that computer literate. However I am keen to learn so if you would be kind enough to tell me how to run it on 64bit I am all ears. I am a bit worried that something else will crash or have to be reinstalled if I make any changes.

 

Thank you Frank, I thought that might be the case. I will stick with what I have for now.

 

Try a portable version of Firefox. I'm linking you to the ESR (extended support release) that doesn't have as many bells and whistles and hence only gets updates for security. This version will work until August of this year. There is no new version every 6 weeks.

Put the download into a folder on your Windows 8.1 desktop. Unpack it there and when you want to run it, click the exe icon. Everything will be saved to that folder - downloads, bookmarks, etc.

 

The portable version work well, thank you
