Firefox will not open at all.

My computer is 6 years old so it is pretty old in computer terms. It has Windows 7 32 bit and 4G of RAM. Firefox has been getting slow for a while but now it just will not open at all when I click on it though when I shut down the computer it says "firefox needs to be shut down force re-start".

I have tried installing and re-installing, deleting all the App Data etc but this achieves nothing. I can't even get the program to respond by going to all programs ans using shift key to open in safe mode. Internet Explorer and Chrome work perfectly and load within a few seconds. I support the ideals of Mozilla and use the browser on my phone and Ipad but I am finally losing patience with it on desk top. Any ideas on how to solve this before I walk away? I have tried every single option you list on your site and nothing.

hi, you could try installing firefox 49.0.2 which contained a fix for a problem that sounds pretty similar to what you've described. you can download this new version from and see if it works for you.

It seems to actually open now but it is still woefully slow: up to two minutes to boot up :(

Firefox takes a long time to start up might be helpful here, now that we have it starting!
