Diễn đàn hỗ trợ Firefox

Hello,

It is not the first time I got that error. I have no idea why.

When I want to start Firefox, this blank window appears (see image). When I click the button or close the window, nothing happens except the window being closed.

I tried to reinstall Firefox, and the autolaucher after the installation opens a Firefox window but, if I close it, I see the error window again when I try to open the program later.

I tried to reset the taskbar's shortcut with the new-one-time-only-working-window-following-the-reinstallation but this did not work.

Please, check for this error. I can not just wait for the program to be ok to run without any logical reason/explanation.

I just installed Firefox to my laptop and noticed that Japanese characters are not working. I tried to change the language from english to japanese because I thought it would install the characters but didn't work and rolled back to english. I need to read japanese texts in webpages.... I also checked text decoding from settings > more > text decoding. Unicode is selected and I cannot change to anything else, it is unselectible. What should I do to be able to use the browser properly?
