Firefox Community Forum

Hello, I am having a problem with Mozilla Firefox on Windows 10.

Firefox sometimes keeps loading continuously and some websites do not open properly or take a very long time to load. My internet connection is working normally, and the same websites may work better in another browser.

I have tried closing and reopening Firefox, restarting my computer, and refreshing the website, but the problem still happens.

Please help me check what may be causing this problem and how I can repair or reset Firefox without losing my bookmarks, passwords, and important data.

Thank you.

After an unwanted and un-needed update, all my tabs closed and I can't find them again. Then after rolling the browser back to a previous version, now all of my bookmarks are gone. I want them back where are they on the hard drive.
