Top 5 Issues of Mozilla Firefox Browser in 2018

Problem 1: Firefox not responding or slow

Feb 2018 Firefox is not working properly. It is slow to load, won’t open pages, or items in Google search. I have downloaded latest version 58.0.1, no change.

Since the last automatic update Firefox has been incredibly slow loading pages, won’t load some at all and has problems showing pictures and video. You keep on trying and it just doesn’t respond. It takes ages to open that too in the new tab. What can I do to fix this?



  • Try uninstalling and reinstalling the newest version of Firefox again.
  • Do a malware check with several malware scanning programs on the Windows computer.
  • Scan with all programs because each program detects different malware.
  • Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox. A small dialog should appear. Click Start In Safe Mode.

Problem 2: Firefox Can’t Play Video

Since Firefox update on Jan 30, 2018 I can no longer play video on any website. I can still play video in IE and Chrome, but not Firefox.


  • Make sure you are not blocking content.
  • Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox. A small dialog should appear. Click Start In Safe Mode (not Refresh) and check if the problem still there.
  • Try disabling graphics hardware acceleration in Firefox.

Problem 3: Firefox Won’t Load Graphics

Ever since I upgraded to firefox 59, everything is broken. Even the new tab page won’t load graphics. I can sometimes get them to appear on mouse over. Sometimes pages load semi-normally, then I restart browser and they broke again.



ESET’s filtering feature can be adjusted to avoid problems with secure sites, either by turning off filtering of SSL connections or by importing ESET’s certificate into Firefox

Check if the Firefox is now displaying graphics?

Problem 4: Firefox 59.0.3 and Windows 10 compatibility issue

Sites that use specific code throw the error message “invalid regular expression flag” and “fatal error” on loading. The errors are only shown if you are using Firefox 59.0.2 or earlier & running it on Windows 10 version 1803 systems.



  • Ensure your Mozilla is upgraded to version 59.0.3 to avoid compatibility issues.
  • To Fix this issue, download & install updated Firefox version “Firefox Quantum 59.0.3 (64 bit)“
  • When you download Firefox right now using the stub installer from Mozilla’s website, you already get the new version 59.0.3 which has the issue fixed.
  • You can run an update check by selecting Help > Menu > About Firefox in the browser.
