Diễn đàn hỗ trợ Firefox

Firefox will only start if I sign in as an administrator. It doesn't connect to the internet, and I can't get to the help screen. I did a refresh but that hasn't help. If I uninstall and then reinstall a new copy correct the problem? How do I save and reinstall my bookmarks and settings? I love Firefox and prefer it over other browsers. But I need to fix it and any help you provide will be very much appreciated. Thank you!

Lost my Passwords on my desktop and can't recover them through profile manager, I found them on my android phone and want to recover my passwords from there, but am worried if I try and sync to the desktop, the desktop might overwrite the passwords in the phone.

FF is offering up possible login names for a particular site I have used previously even though I have removed all related browsing history, form data, and cookies (and cleared the cache). What am I missing? Is it using stored history for unrelated sites to guess at a user name, or is there some other hidden history I need to clear?

When I'm on my phone and signed into my Firefox I want to be able to send tabs to my desktop. I'll click the three dots on my Samsung 20fe, click share, and click send to device. My p.c. is listed and when i click on it, a box pop's up and says "tab sent. I don't know where it's going, but it's not making it to my desk top. I've tried logging out and logging back in. on both devises

Hi Everyone,

I’m Harmandeep Singh Kandhari from India, A Health and Wellness Motivator and Now, Recently, my Mozilla Firefox browser has started using much more memory than usual, and multiple tabs cause noticeable slowdowns. I haven’t installed many new extensions. What steps can I take to identify the cause and optimize Firefox performance without resetting my entire browser profile? 🦊💻

Thanks, Harmandeep Singh Kandhari

with this new version i lost everything i need to get back to an older version and get all my extentions my bookmarks back all my s desktop items that i had linked to firefox are gone i can no longer get face book or anything back to firefox book marks every thing i had with firefox

and

I use Brave, Firefox, Firefox Developer Edition and Thunderbird. Brave: 600mb Firefox Dev: 600mb Thunderbird: 200mb Firefox: 800mb Why is Firefox using too much memory? Especially as I am running Firefox Dev as a direct comparison. I don't have any plugins on Firefox. Firefox Dev has uBlock Origin alone. Brave has a few plugins.

Hello Folks, I just importeda a new certificate. Then I wanted to save all my certificates for backup. Selecting "Backup all...", I neter a secure password and click ok just to get the following error message: Failed to create the PKCS #12 backup file for unknown reasons the only button is "OK"

How can I start finding out what is going on and is there any means to save my certificates?

I rarely turn my laptop off, when I'm not using it I put it into sleep mode. Firefox absolutely hates this though, and after a few days it will slow to a torturous crawl. Everything becomes horribly irresponsive, feels like nails on a chalkboard. It can even get to the point where it will randomly delay my cursor in Windows 10 itself by 10 SECONDS along with some bleed into other programs while switching between them. Fully closing Firefox then re-opening it will reset the issue, starting the timer again, but I hate doing this because I have doing that set to log me out of various sites which I then have to re login to, letting the torture boil until I give in. This has been my Firefox experience on laptop for at least 5 years now. Other forks of Firefox have this same issue.

I am leaving Firefox in the torture state currently to troubleshoot here. Currently the memory usage on Firefox is 6GB at 54% of my total ram, which is being used at 84% total. Total CPU usage is 23%. Wrote this on my desktop for my sanity so that's why there's no troubleshooting information.

Not sure if "browse" is the correct topic but here we go:

After a random crash (I don't remember the details, been a while) I've "refreshed" Firefox. Following that I started to have some problems with Google Meet. Haven't had any for years and suddenly when i open Google Meet (working from home and using Google Meet as an online meeting platform daily), everything becomes unresponsive. I can't change tab, cannot close Firefox from the close button, nothing. I open the Windows Task Manager and End Task manually to close the window so I can restart the browser. After restarting Firefox and launch Google Meet, it doesn't crash.

The other problem is when I try to watch something on Netflix, I hear the sound, see the subtitles but the video content is not present. It's just black screen with UI on it. Yes, I checked the DRM setting and no, other streaming services that I use don't have this problem. I can bypass this by launching Firefox in troubleshoot mode but I want to use my extensions. I even tried to enable them one-by-one to see if anyone causing problems but even when I disable all of my extensions like in the troubleshoot mode I'm still having the same problem.

I tried several solutions that I found on reddit etc. but nothing worked so far. I also re-installed Firefox and nothing changed.

Please help me before I lose my mind (:

Good Morning! I've just come back to FF after using another browser for quite a few years. Things have changed alot here, but I'm loving it all so far! With that being said, have been trying to get a few extensions set up. Main one being Open Link with New Tab. (WHY doesn't FF do that automatically? lol.) Anyway, obviously I'm doing something wrong because it just stays grayed out. I've uninstalled/reinstalled quite a few times. I know it's something so basically simple and I'm overlooking it. HELP! Thanks! Lynn

javascript contains the following code:

var txt = "<tr><td" if (SecIndent[i] > 0) txt+= " class='In" + SecIndent[i] + "'" txt+=' onclick("' +'go2('+ "'_" +i +"')"+ '")>' +SecNames[i] +'</td></tr>' alert(txt) // txt += ' onclick("go('+"_'><a href="#_'+i+'">'+SecNames[i]+'</a></td></tr>' document.write(txt); }

seems to be working right -alert displays: <tr><td onclick("go2('_3')")>Chapter 1 – The Number Tiles</td></tr>

when I inspect element it shows <td onclick("go2('_3')")="">Chapter 1 – The Number Tiles</td>

where did the extra =" come from? when I tried other browsers still problems but inspect element was different hopefully this isn't a Windows 10 problem, but very wierd if it is

Since changing to a new internet service provider, I can no longer print form Firefox. My internet router uses the same username as password as my previous router.

If it ain't broke, don't fi(o)x it. Never try to be too clever. I cannot log out of OUTLOOK.COM, then after goodness knows hot long, it says that I have been kicked out and need to login again. CRAP!!!!!!!
