Hi   !

You can try these steps in case of issues with web pages :

Reload the page and bypass the cache to refresh possibly outdated or corrupted files :

Hold down the Shift key and left-click the Reload button or press 'Ctrl + F5' or press 'Ctrl + Shift + R'

Another thing to try : Clear the cache and cookies only from websites that cause problems.

Clear the Cache:

3-bar menu => Options => Advanced => Network => Cached Web Content :
"Clear Now"

Remove Cookies from sites causing problems:

3-bar menu => Options => Privacy => Cookies : "Show Cookies"

Any difference  ?

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is causing the problem.

• switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Appearance
• do NOT click the "Refresh Firefox" button on the Safe Mode start window

You can remove all data stored in Firefox from a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History -> Show All History" or "View -> Sidebar -> History").

Using "Forget About This Site" will remove all data stored in Firefox from that domain like bookmarks and history and cookies and passwords and cache and exceptions, so be cautious. If you have a password or other data from that domain that you do not want to lose then make sure to backup this data or make a note.

You can't recover from this 'forget' unless you have a backup of involved files.

If you revisit a 'forgotten' website then data from that website will be saved once again.
