Several things you can try.

Open your firewall program. First check the settings. Make sure that the program is set to tell you if a new program wants access to the web. Then go to the list of programs the firewall has. Make sure that all the programs you want to access the web are set to ALLOW. If it is set to AUTO, the firewall may not allow access.

Hold down the Shift key (On Mac the Options key) while starting Firefox to start in Safe Mode.

Let us know how you do. BTW, we are all users like you, helping out where we can. One day, you may be the one answering questions.

Thank you so much! My husband was able to fix firefox on his computer. I tried but failed. He told me that all he did was open up a new browser and it corrected the problem he was having. I will save this for future reference.

Can you explain what your problem is?

Cannot see back button home button or downoad arrow How do I get them back?

Hi jqa2003

Your problem is different than the problem this question is about.

Could you please start a new thread for your question instead of posting in an existing thread?

Then you can provide more information like your operating system and installed extensions and installed plugins.

• check that "Bookmarks Toolbar items" is on the Bookmarks Toolbar
