hi, could you go to the firefox menu ≡ > help ? > troubleshooting information, copy the contents of that page and paste them here into a reply on the forum (or if it's too long through a site like https://pastebin.mozilla.org/ and provide the link here)?

this might give us a clue what is going on. thank you!

thanks, can you please try to update your intel graphics driver: https://downloadcenter.intel.com/download/27266/Intel-Graphics-Driver-for-Windows-15-60-?product=96551

I tried to update the Intel drivers from the link but it didn't work. So I visited the Acer website to get the latest Intel drivers for my PC. But the update haven't changed anything. The screenshot shows how my PC displays Firefox 57.

ok, in this case you'd probably have to disable hardware acceleration within the firefox settings and see if this improves things: Firefox's performance settings

That's even worse: It causes that the window displays for half a second and then it disappears.

it's interesting that your original question was captured as coming from windows 8 whereas your troubleshooting information said win10 - can you please right-click the firefox icon on your desktop, go to properties > compatibility and make sure you haven't enabled any compatibility settings there...

here someone was reporting a similar problem (with a different solution than recommended so far): https://www.reddit.com/r/firefox/comments/7ckcgw/my_firefox_quantum_bugs_that_i_cant_solve_cant/

Well, disabling the Accent color really fixed it. That's Windows 10 logic xD. But it's very annoying to be forced to work with black Windows 10 the whole time just to be able to run Firefox normally :( I hope it will be working better in a future release but Thanks a lot! :D
