Disabling either the "Allow Firefox to send technical and interaction data to Mozilla" or the "Allow Firefox to install and run studies" options under the Privacy & Security settings page break all of my homelab SSL certificates using Let's Encrypt and breaks the tab/card preview functionality. The only way for these to work is to leave both options enabled. Disabling either one breaks both of those.

When they are disabled the card preview just doesn't work. The Let's Encrypt-backed self-hosted services are a bit different. I get a warning that the pages are insecure, and if I click the Advanced button to continue (sometimes it is there and sometimes it is not) I get looped back to the same insecure page with no way to accept or proceed.

Things I've tried: - Disabled all Add-Ons - Deleted/reverted all modified settings in about:config - Firefox Refresh - Uninstalled/cleared cache directories/reinstalled - Deleted my whole Mozilla account and recreated, thinking it was a bad setting being synced

This is not an issue on Firefox for Android seemingly. This started on my laptop first a few weeks ago, I don't remember changing either of those privacy settings at the time but I may have.

Hi, I'm a new user switching from Chrome. I've downloaded Firefox Developer Edition, and it's a fantastic product. I'm really satisfied with it. However, the only thing I can't figure out is how to enable JavaScript editing directly from the developer tools. Could you please let me know if there's a way to do this?

Thanks a lot!

I have Autofill turned off for addresses, but Firefox asks me to save anytime it sees an address. Yes I have turned it on, restarted and then turned it off and restarted. It still asks me if I want to save address. I work in a school and do data entry and updates on addresses every day. I need this fixed.

G'day from 'Straya!

I have migrated Thunderbird from one Windows laptop to another, copying the profile and all included files. This mostly worked but has created a couple of issues I am trying to troubleshoot and could really use some help.

First thing probably worth noting is that I had an earlier version of Thunderbird on the old laptop than the new one downloaded to the new laptop. I don't that if that is the problem.

I have two email accounts which are both using IMAP. When I delete an email in Thunderbird, it keeps coming back and I now have multiple copies of that email. My storage is filling up 😒 Is there a setting I am missing?

Additionally, the migration does not seem to have brought over my contacts. Did I miss something?

Any help and advice will be greatly appreciated.

WHEN I DOWNLOADED A PDF FILE IT WAS AUTOMATICALLY SAVED AT FILE DOWNLOADS. MAYBE I ACCIDENTALLY PRESS SOMETHING AND NOW WHEN I PRESS DOWNLOAD IT OPENS THE FILE AT A NEW TAB. TELL ME HOW TO FIX IT PLEASE

i have recently acquired a new PC and want to transfer all my Firefox settings to the new PC and have two questions:- (1) What file and what location do I post the file for Homepage shortcuts which involves 4 rows x 8 = 32 shortcuts that I want to transfer to the new PC without having to do it manually. Apparently Sync wont do it for some reason that I fail to comprehend. By searching this site I have found answers that say the file "prefs.js" hold these values. However, I have copied that file from my old PC onto the new PC but no result? Where should the file be copied from and to (full path from and to)? i have used "about:profiles" but then there are paths to "default" and "root". (2) I have exported the the Bookmarks from my old PC to the new PC but in one particular case the bookmarks are not the same. In this case I have a particularly large bookmark that contains three (3) Sub-Folders plus many individual bookmarks. When importing the file it does not include all the sub-folders - only two. This baffles me because if is exported with three sub-folders I don't understand how the imported Bookmark file can be different. Any advice would be most appreciated.

I use firefox on my android Fairphone to play podcasts and videos because I don't want to have a zillion more apps and this matches the way I use the net on my laptop anyway.

One thing that bugs me is the notification bell every time I start watching / listening, and then the notification sound when it stops.

I've checked through the android settings (version 13) but I can't find it. Is there a control in Firefox which is causing the notifications?

I need to build firefox android with an extension installed. I'm trying for ublock origin now but I'll use my own extension later. I do not plan to submit this or whatever,it'll be local. How can I do it?

Hello, I am having an issue when playing videos on youtube or youtube music on firefox (android). While I can unpause the video / music with the tab being in the background (different tab or even app is focused or even with locked screen), for some reason whenever I am currently focused on the youtube tab and leave it (lock screen, move to different tab or minimize the app to go to home screen/different app) the video will pause and I will need to unpause it again. Does anybody have a solution for this?

Hi there-

On my current Dell laptop (Windows 11) I have had a recurring issue with Firefox wherein any time two sounds play at the same time (say, a Youtube video is playing in the background and I have a sound play in a browser game) it makes one of the audio channels cut out for about a second. This issue only happens with Firefox, and I previously fixed this by changing the bitrate in my audio output settings. However, after an update, this issue has returned, and the bitrate settings I was using that were able to fix this issue now doesn't allow me to play audio on Firefox at all. So now I have no way to avoid the strange bug that causes audio to cut out.

I would love some advice- is this on Firefox's end, or my computer's? Is there a driver I could install or something to avoid this bug? What causes it?

Cheers, Noa
