Firefox Community Forum

i had setup a new windows and when i tried to sync my Firefox data i found nothing and all my bookmarks and passwords was lost.

i need you support to recover my data.

Hello

I reinstalled windows 10 on my laptop with keeping my personal files intact. During the installation process Firefox was removed. After Windows was back I reinstalled Firefox and it works just fine except none of the old information, passwords, bookmarks etc are there and I tried just about everything to retrieve them but no luck. I tried to bring up profiles but only the new one was listed as default. What can I do? Thanks for your help.

Hi, I accidentally did a refresh on my Firefox (Win 11) and therefore I now have an "Old Firefox Data" folder on my desktop and Firefox is completely almost back to stock.

I have lost all extensions, customizations, settings and other configurations. Luckily, I had taken a backup of my bookmarks prior to doing this.

How do I return everything (including extensions) back to pre-refresh state?

Thank you.

Firefox consumes almost 2Gb of RAM with only one tab open. I find this surprising, and it's a major performance issue for me.

Do you have an explanation or solutions to reduce this memory overconsumption?

My about:config contains this:

extensions.quarantinedDomains.list autoatendimento.bb.com.br,ibpf.sicredi.com.br,ibpj.sicredi.com.br,internetbanking.caixa.gov.br,www.ib12.bradesco.com.br,www2.bancobrasil.com.br

I'm in Canada though. Any idea what its about?

Recently I started using Bit Defender. I have been getting these security messages: Suspicious connection blocked now

Feature: Online Threat Prevention

firefox.exe attempted to establish a connection relying on an expired certificate to updates.tb.ask.com. We blocked the connection to keep your data safe since websites must renew their certificates with a certification authority to stay current, and outdated security certificates represent a risk

Hi all,

Since recently Firefox keeps redirecting me as if I'm in Switzerland where I haven't been to ever since I use the internet. My location is in Croatia. I have tried to clear cache, cookies and browsing history multiple times, use incognito mode, my language is setup to English and I don't use VPN. Nothing helped. This unfortunately requires deeper dive because I can say for certainty that an individual who illegally surveils my device deliberately made this change and something needs to be done on Mozilla's end. Is there a way to directly contact Mozilla's support or what would you suggest to do to solve this issue?

Many thanks,

Lana

A couple of days ago, my work laptop popped up a message that said: (from firefox) couldn't load XPCOM (OK)

Today, same work computer, another message popped up from firefox: Entry point not found. The procedure entry point ?WindowsOleAut32initialization@mozilla@@YA_NXZ could not be located in the dynamic link library C:\Users\Berlye\AppData\Local\Mozilla Firefox\xul.d

I have absolutely no idea what this means except that FireFox will not open. I am a very senior citizen and totally electronically challenged, so I need help in a-b-c fashion as to what this means and why I can't open Firefox on my work laptop.

Thank you.

Firefox old tabs keep opening when I restart the browser. I have the box unchecked on the startup option to open them. I have the problem on my Mac Studio and my macbook. How can I fix this please.

I am no longer able to log into my Spectrum email using Firefox as my browser. I can login using Chrome. Firefox worked fine until I tried logging in on November 21 and then I ended up in a loop. I can access other parts of Spectrum, just can't get to mail. I have it set up to transfer to Outlook and than works fine. Spectrum says there is nothing they can do about it.

Has anyone else had this experience? If so, were you able to resolve it?

I recently upgraded to the latest version 132.0.2. There's a vertical sidebar on my browser that I would like to remove. I looked into the customize sidebar settings but can't seem to find a way to remove it completely. I've also attached a screenshot. Any guidance would be appreciated. Thanks!

1. some webpages extremely slow loading while others are fine. All load fine on Chrome. Why? Particularly true with https://www.tab.com.au/ that I use 2-3 times a week. In Chrome it's immediate connect.

2. cannot sign in to my members account on (eg) Choice but easy on Chrome. Why?

Love Firefox when it works but I'm getting so frustrated. Seriously considering going back to Chrome - reluctantly.

Also so many website/page freezes & non responses over last ~3 months. Grrrr

For several weeks now, whenever I try to log in to a google account, Firefox crashes. The crash happens on the screen where you enter your email address, before the page where you enter your password. I start to enter my email, and about 3 letters in to typing my entire browser freezes. The crash also happens in troubleshooting mode, so I know that it isn't a problem with one of my plug-ins. This isn't an urgent issue, I can get by with the gmail accounts that are already logged in, but it is really annoying.

I have had Windows 11 added to my computer. I do not like the ookmark tool bar. Is it possible to have my bookmarks listed vertically on the left side of my screen like I had previously in Windows 10?

A continuous stream of "antivirus" via tomp3.cc popups started appearing today on my Win 10 desktop. Although there is a "Dismiss" button, once pushed the popups return immediately. I have not changed any settings, added/deleted programs. My Firefox is up to date. I have run Windows security and my Bit Defender program with no detection(s) noted.

I visit an app called tool finder and this happen on my zen browser the banner automatically becomes dark and all the text are not visible. And I tried to troubleshoot it by this process: 1. I tried to compare my desktop snipping tool to capture the page looks and its dark. Then when I try using the screenshot tool from the zen browser it becomes white. The second image is the screenshot from the zen browser 2. I switch the workspace and use my second workspace and when I tried the link it also becomes okay.

I want to know how to fix this issue because I haven't seen anyone having this kind of issue. Thank you and I am currently inloving using this zen browser and hopefully this problem will be fix immediately because I want to see the look and feel and the right color in my screen. Thank you!

I have Fedora 41 with GNOME 47.1 and run Firefox 132.0.1 Installed KeePassXC Browser Integration and configured to include Firefox and Chrome. In Chrome it is detected but not in Firefox ... it has worked before and I suspect it has to do with upgrade to Fedora 41 & GNOME 47.1 Anyone who has the same problems?
