Pages show a blank screen
Sometimes, really randomly when i do a search or go to a website, the page loads, but shows a completely blank screen as in the attached file. There is no problem with my internet connection as other browsers can visit. If I clear cache, this becomes ok, but this happens at least twice a day, and its very annoying. This happens with Windows and Linux versions. Both are running v43.

This happens to me sometimes as well, and I have been trying to find out which add on it is that does it. If you browse in Safe Mode for a while do you ever run into it, this might help eliminate the add on theory.
Try Firefox Safe Mode to see if the problem goes away. Firefox Safe Mode is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes).
If Firefox is open, you can restart in Firefox Safe Mode from the Help menu:
- Click the menu button
, click Help 
and select Restart with Add-ons Disabled.
If Firefox is not running, you can start Firefox in Safe Mode as follows:
- On Windows: Hold the Shift key when you open the Firefox desktop or Start menu shortcut.
- On Mac: Hold the option key while starting Firefox.
- On Linux: Quit Firefox, go to your Terminal and run firefox -safe-mode
(you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
When the Firefox Safe Mode window appears, select "Start in Safe Mode".
If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, theme, or hardware acceleration. Please follow the steps in the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article to find the cause.
To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.
When you figure out what's causing your issues, please let us know. It might help others with the same problem.
Does the missing content fill in if you reload the page (either Ctrl+r, or Ctrl+Shift+r to bypass cached files) or try changing the zoom level?
You can check the log in the Web Console for error messages and the Network Monitor (Firefox/Tools > Web Developer) to see if content fails to load or is possibly blocked.
Use Ctrl+F5 or Ctrl+Shift+R to reload the page and bypass the cache to generate a fresh log.
seems like i managed to figure it out. Ever since i disabled the extension called Nightmode Pro, i havent faced it. Will keep monitoring
