After updating Firefox yesterday and restarting my Win7 I was unable to open my Firefox. The error message was "Can't open this item. It might have been moved, renamed, or deleted." I was given the choice to remove it or not. When I chose not, the event and error message reiterated; so I chose to remove. Thereafter I've been unable to bring up or download Firefox, with the following error message with each try:
XML Parsing Error: undefined entity Location: chrome//browser/content/browser.XUL Line Nunber 50, Column 1:

Hours and hours wasted trying to stop floating videos, pop-unders and overlays. DO NOT tell me to do about:config ! I did it all through exhaustive research. No effect. The solutions are all over the place and VERY repetitious. Every permutation of suggested FF fixes have been tried. Am a very savvy Windows user... It goes round and round and round and round and round in circles...
Daily I am plagued by floating videos, pop-unders and overlays. It never ends. Once again -- DO NOT tell me to do any more about:config -- it has all been tied an tested. All the settings are as suggested...

After a recent automatic update my old problem with Firefox Quantum came back. Every time I open Firefox browser I get multiple 4-6 firefox.exe running in the background processes. When I go into details and try to end process tree it crashes my browser. When I open Firefox it starts all over again. I have gone into about:preferences and
De-select ‘Use recommended performance settings’ Set Content process limit value to ‘1’ from its default value
I have also gone into about:config and switched browser.tabs.remote.autostart to false. Still have the same problem.

Firefox detected a potential security threat and did not continue to www.google.com because this website requires a secure connection.
What can you do about it?
www.google.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.
The issue is most likely with the website, and there is nothing you can do to resolve it.
If you are on a corporate network or using anti-virus software, you can reach out to the support teams for assistance. You can also notify the website’s administrator about the problem.
