Diễn đàn hỗ trợ Firefox

I have to do a clean install of Windows, how do I save all my firefox bookmarks and passwords as well as Thunderbird addresses and any other info I might want to import back into Firefox and Thunderbird once I've installed windows again.

I "create a new profile" days ago what I first received the notice to update. It seem to work except when I click on a url to view. I received instead the notice that I am in the old firefox and to "Update". I did again and it seem to work until I clicked a url to view and again received a notice to "update by creating a profile.

It's very frustrating - Now I can't open firefox at all. It wants me to "fix it" or create a new profile"

For the second time, FF opened w/o restoring the previous session's tabs. The first time I was able to restore the tabs. This time I can't. And can't figure out how to fix it or why this is happening since I have the restore previous session box checked.

Hello,

I recently updated my Firefox browser to the latest version, 138.0.1 (64-bit), on Windows.

After the update, I noticed that when playing videos in fullscreen mode (for example, on YouTube or other video websites), the Windows taskbar (the bar at the bottom of the screen with the Start menu icon) does not hide automatically. This is affecting my fullscreen viewing experience.

Before updating to version 138.0.1, the Windows taskbar would hide correctly when entering fullscreen video.

I was wondering if anyone else has encountered a similar issue with the Windows taskbar not hiding, or if there are any suggested solutions to help resolve this problem.

Thank you for your help!

I want to turn off a recently added search bar icon in the new version of the newest version of firefox ? I only use google and don't have other search functions enabled but i dont like seeing this icon that suddenly appeared without warning ?

It is too distracting.

I shutdown my laptop. When it came back up, my fire fox pages were gone. I have the sync option on so I don't know why I lost all of my stuff, files, and documents.

I'm trying to access Tiermaker but it won't let me because it says it is insecure. On other browsers, however, I can access it fine without any warnings. I don't have any accounts on there or anything that could be at risk. How do I access Tiermaker?

Hi, I want a website (Protonmail, my email client) to store persistent data. I have enabled it, but I also have all my browser security settings on Strict (also clearing browse data and cookies on each closing of the browser), so now when I have downloaded the data and I close and reopen my browser: it's all gone. I tried looking at making Protonmail an Exception, but that's only possible in relation to Tracking Protection. How to fix this?

Thank you in advance,

Kind regards,
