How can i hide my display/screen resolution from websites? I use Firefox in windowed mode not with my default screen size but websites know my default resolution. This can be used to identify my pc. I dont want that for privacy reasons like tracking and adverstising. How can i prevent this? I found many threads/posts about this in various forums/websites. They are talking about Tor Browser and that websites can identify you if using full-screen mode. But as i said, im using Firefox not Tor and while im using windowed-mode websites still know my default resoltion. I tested this on https://whoer.net/

Another question, how can i restore the default window size in Firefox?

I recently installed Firefox Developer Edition on a Debian system. I synced my existing profile. There is currently an "import bookmarks" tab displayed that I am unable to delete. I see other existing questions asking and answering this problem, however, I do not have the "customization" option recommended.

Hi,

during maintenance of my logins in my password manager I discovered that I still have the login data for a FireFox Sync account. I can login to that account and see my settings, but I actually want to delete the account completely. The problem: The mail address associated with that account does not exist anymore (changed the company). When trying to delete the account (or when trying to add a seconday mail address), Firefox Sync prompts me to enter a verification code that was sent by mail.

I'll never receive that code, as that original mail adress does not exist anymore.

How can I delete that FS Sync account?

Thanks, Frank

Tried to reply to your email. It has not return. Here is a copy of report you requested. It is different from what you sent me.

> Task: invalidateCaches - Unable to invalidate caches > Task: checkCoherence - The task queue was cleared by an error in another task. > Task: expire - The task queue was cleared by an error in another task. > Task: originFrecencyStats - The task queue was cleared by an error in another task. > Task: vacuum - The task queue was cleared by an error in another task. > Task: stats - The task queue was cleared by an error in another task. > Task: _refreshUI - The task queue was cleared by an error in another task.

I still have no bookmarks. I have restarted the computer a number of times. I also renamed the places.sqlite adding a 1 after places as it said in other directions. I have also refreshed.

Yesterday, I uninstalled Firefox and reinstalled after receipt of your response. It said all cookies, history, bookmarks etc transferred successfully. However, I keep getting the message “ and Bookmarks and history systems will not be functional because one of Firefox’s file is in use by another application. Some security software can cause the problem. I use McAfee, I’ve always used it. I have not changed it.

I did not do anything with favicon file as I don’t know what to do, I understand you can delete that. If there is a list of more than one, then what do I do.

As I indicated, I an NOT a technical person.

Please advise.

Thanks.

hi,

Maybe someone had the same problem, I use two security option outside of Firefox: 1. /etc/hosts file, all the site that I do not want to allow my machine to interact with; source: https://github.com/StevenBlack/ 2. VPNs anti tracking scripts

I use a mac, Mac OS 11.6 Firefox 93.0


With all the two security option enabled, Safari works fine, TOR works fine, Firefox has massive issues with loading pages speed. Some of the Firefox settings: Network Settings: the DNS over HTTPS is OFF, as I am using a VPN Privacy and Security: set to standard, but there is no difference is loading speed when switching to strict Extensions: I use 1password, multi account containers and user agent switcher; no difference is loading speed if I disable or remove all extensions

Any idea why is Firefox loading page speed effected?

Many Thanks Michael

I've just set up Firefox Sync, but it is only working one way. I can see my computer's tabs from my phone but I cannot see my phone's tabs from the computer - if I use the quick access "Show tabs from other devices" it just spins a loading wheel with "Syncing".

Also, the "Send Tab" option when you right click a tab does not appear at all. Sending a tab from the phone to computer does not result in anything appearing on my computer.

Everything is set to sync on both devices, and I have tried to sync it manually. Both versions are up to date.
