Firefox Support Forum

I use a MacBook Pro. I recently created a new profile for Firefox (for work purposes) and set it as the default profile, because I'm trying to get off Chrome entirely. The preexisting no-longer-default profile contained all my "personal" data - bookmarks, extensions, etc. Continued using both profiles for about a week with no issues. Last night my MacBook updated and when I reopened Firefox, the new default profile was fine, but when I went into about:profiles and launched the secondary profile in a new browser, it was completely empty - no history, no bookmarks, no extensions, nothing. That's at least a year's worth of data completely gone. I've looked through support articles and past folks' questions and am just completely lost as to how to restore it or what went wrong. If it's not possible to restore that data, how can I at least prevent this from happening again? I've very much lost trust in Firefox profiles because of this. Help please?

Dear Mozilla Team, I hope you're doing well. I have a question because I am not sure about things how works when someone changes a device. 3 days ago I changed my Mac device to a new one and however I logged in with my profile my Mozilla Firefox looks completely different and I would like to know which version I used let's say a week ago and what is the version now, is there a way to figure out this? Honestly, I don't like this version and I would like to get back the old one or the old customization. Can you check this for me please? Thank you, Richard.

Why is

"m@moz-extension://7010c318-ea8f-4(?)"  populating in my Password Managers log-Ins whose websites require passwords ? This prevents log in information from auto populating?
                                      Thank You to the community and anyone kind enough to help.

I'm using Firefox 120.0 on an iMac running OS 13.6.1. When browsing in an open window, merely moving my iMouse (no clicking) causes the display to zoom in and enlarge the display a huge amount that is much larger than normal zooming can produce. Please provide a solution.

Hi,

I lost all my bookmarks because I forgot my Firefox account password and didn't realize they were in the cloud (I thought they were stored locally). I don't have any bookmarks backups, but I did recently back up my Macbook via Time Machine. Would Time Machine be able to recover my previous bookmarks? If so, how?

Thank you.

when i am opening any streaming site and play the video, the audio stream of the video sometimes start late and some time does not even start when the audio is played via bluetooth audio device.

Unless I'm crazy, Firefox used to import the tags in an exported bookmarks HTML file. I used this to move bookmarks between profiles. What happened to that capability?
