Diễn đàn hỗ trợ Firefox

I am unable to bookmark anything. Some suggestions are to open a new table then type about: profile and then hit restart. When I do that DuckDuck then searches profile.

Currently when I click a link in and email, it always opens in Microsoft Edge even though my computer has Firefox as default browser. Is there another setting I'm missing?

General Default browser

Firefox is your default browser. Good choice.

Firefox kept losing all of my saved bookmarks and passwords. Each time it updated everything would disappear. I went to the folders where the bookmarks and passwords are stored and the profiles were there but Firefox did not list them when I searched (about:profiles). Tried numerous times to move the files to the current folder but the program still could not see them. Tried copying, moving, changing names of files, etc. Finally uninstalled firefox and attempted a new installation but it will not even open because it says it can't find profiles even though there are profiles in the profile folder. Now what do I do?

VPN has appeared at the top of the screen with an option to click the GET STARTED button to try the built in option. I haven't done so but now can't access a website I regularly use. Their tech team tell me that the VPN is blocking access. How do I disable this when I haven't asked for it so don't know where to find it

I'd like to try the new Firefox VPN, but I can't find the icon to turn it on, not even when I customise the toolbar. I searched several times. I know the VPN is available in my region (the Firefox browsers at work all have the VPN icon), but once I enter my email and password for my Mozilla Firefox account, the icon disappears. What should I do?

Thank you in advance!

Two questions; First is why does the Taskbar show "Firefox (2)" (see first image) Second: When trying to troubleshoot, I open Task Manager, and with just one tab open, I see Firefox (13); confirmed when the line is expanded. What is going on here and is it impacting Firefox performance; see 2d and 3d images? (Phone camera photos as PrintScreen is disabled for Task Manager which doesn't seem smart)

I had sync turned on before I reinstalled my OS, and now I have lost everything. Is there anyway to recover the stuff that should be there? Yes or no. If yes please provide steps, and not the self help articles here as they are worthless.

I just got a samsung galaxy s26 (old phone is not available); when i accessed my Firefox, my Collections were missing. From other research, it seems that Collections are not available anymore. However, there must be some way to recover the websites that were stored within them, so i can at least rebuild them.

What do I need to do to disable, hide, or eliminate the horizontal scroll bar? One is displayed when I open spreadsheets using Google Sheets, which ends up blocking information that is normally seen.

I'm on Windows 11 and have the current Firefox installed.

Thank you.
