In the info that came when you posted there was a crash report and it is showing EXCEPTION_BREAKPOINT, this is usually associated to Video Card Drivers.

See if you can find updates for your IYour Intel(R) HD Graphics 4000 as they are A VERY old : Driver Date: 3-19-2012 You can Google Intel(R) HD Graphics 4600 and find the download page https://downloadcenter.intel.com/product/81499/Intel-HD-Graphics-4000

Can also try : https://www.intel.com/content/www/us/en/support/detect.html it should find your Video Card and Your Sound Card and show you drivers for them.

I see a few errors in the drivers so this is possibly a reason your having issues with Firefox 57. Please stay up to date on the drivers after as old & or corrupt drivers can cause a wide range of issues, some hard to identify as the video card being the issue.

Hi Pkshadow Thank you so much for your help.

I have upgraded the HD Graphics 4000 drivers as you suggested.

Also i tried to turn off hardware acceleration through options but it would not open. so i use the about:config to set these to true: "gfx.direct2d.disabled" "layers.acceleration.disabled" "media.windows-media-foundation.allow-d3d11-dxva" "webgl.disabled"

However its still the same. when i enter a url into the address bar and press enter nothing happens. Same as when i tried to open a new tab also nothing happens.

Any advice would be much appreciated :)

thanks, one more thing that i have just noticed when looking at your system details - can you please test if the following steps can fix the performance issue you're seeing in firefox 57?: enter about:config into the firefox address bar (confirm the info message in case it shows up) & search for the preference named accessibility.force_disabled. double-click it, change its value to 1 and restart firefox once.

then please let us know how this goes?

Thanks philipp. i have just tried the accessibility.force_disabled to 1 as suggested. However its still the same.
