I've installed firefox in my laptop, and I want to use it in my PC with same bookmark, settings, cookies.. all same

What I have done is: I copy Firefox (whole folder where firefox.exe exist), then apply the profile. It works well, no trouble until now.

But, I have question: is copying whole installed firefox to another PC (without installation) is okay? From security and privacy perspective..

Windows 10 pc can not start,I have gone through automatic repair and diagnostics steps,but am now on advamced options and think I need to Reset it.This will lose Firefox.When I install it again will I be able to sign into my Firefox account to retrieve bookmarks and passwords?I am very nervous about this,don't even know how to install Firefox,as someone gave me the computer and it was already in there. I am a tech dinosaur!Thank you in advance for any help.Lesley

I have installed Firefox on my android phone now that I have installed Firefox browser on my desktop. Trouble is when I run it (on my phone) it very briefly flashes black & white blocks on screen and then makes my phone reboot. I have a Samsung galaxy S4 with android 9.0 (pie) installed. Is there anything I can do to make it work?

I am trying to create a new Firefox account with it's own email to be separate from this Firefox account I am posting from. However, every time I try to follow the "sign up" buttons I get redirected to the login page where I enter what I want as the new account info and receive a "Primary email account required for sign in" The email I'm trying to use for my new account is NOT registered with Firefox and I am using a freshly installed version of the browser on a new PC so no extensions are interfering.

I was trying to customize the toolbar and I can't recall how, but I lost access to my extension shortcuts through the menu list button on the toolbar. I've been since trying to get the button back or replace it, to access my extensions that way but I'm not finding any options to get the button back which I find ridiculous because the button is very helpful on the toolbar in utilizing your extensions. I'm kind of a newbie so I'm looking for help in how to get the button back on my toolbar so I can utilize my extensions that way, please. Thanks.

My title bar has a weird symbol in front of where it says Mozilla Firefox

Sort of looks like a yen symbol and the m of the Mozilla Firefox looks weird as well

Posting on mobile devices other wise would attach photo

After updating my Windows, I had a problem with Firefox and several other programs not opening. Please help me how to fix Firefox.

Error phrase :

(V The application was unable to start correctly (Oxc0000022). Click OK to close the application.)

Since this morning Firefox keeps crashing on my PC, not only tabs, but the whole browser. I've sent countless reports so far. There is no error message. Is there a problem with Firefox today, or there may be another issue? Please help, thanks.

I saw this same issue posted on here, but I press the shift key while using the Firefox browser and what appears to be a developer menu pops up at the bottom of the page, the crappy thing is this is occuring on my laptop so my keyboard is part of the computer lol

I downloaded session manager on Firefox hoping to be able to import session file from session buddy from chrome. I tried importing the json file but it says it fails to read. Followed by some googling I found that the problem lies with the fact that session buddy files don't have several tags in current tabs in the json file so importing fails. Like mentioned here https://github.com/sienori/Tab-Session-Manager/issues/408#:~:text=Close%20Chrome%20and%20Open%20Firefox,%2C%20and%20click%20%22Open%22. I am a noob and I don't see how that could be fixed, any help, plz?

When I close tabs, and the computer stops working and I check the Task manager it turns out that firefox still runs 20-30tabs in the background when most of then have been closed and have just 4 running!!!

This occupies 100% of disk and CPU, and thw laptop stops functioning and freezes!!!!!!

And this happens all the time! How do we make firefox actualy close the tabs properly?? Without having to dig through task managerto close them again one by one?

W10 and newest update are not compatible. I seek help using Android, because firefox is no longer usable on Windows 10. It started with the tab toolbar using up a large part of the screen and fonts being huge. When I tried to adjust fonts they became too small too read. Dwngrades threaten my profiles, a real low blow. What do I do?

I have installed browser and I'm trying to request for data to some websites like social media but from my browser no one serves are responding and I have stable internet connection to my laptop please can anyone help me with this issue..
