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?

Firefox has been my default browser for longer than I can remember. Over the years, I have maintained a significant bookmark file for work. I recently purchased a new computer, and my zero bookmarks from the new computer have replaced all of the bookmarks that I had in my old browser. This is a bookmark file that has successfully followed me through multiple computers and even my ios devices. And now it seems to be completely gone. I've looked at the places.sqlite files, and the largest one is 20MB and is in my current default profile, but it is dated today. That makes no sense because I do not have any bookmarks on this older computer, and my new computer doesn't have any either. The bookmarks have also been completely deleted from my iPad, but miraculously are still on my iPhone (evidently I had signed out of Firefox for iPhone at some point so they do exist somewhere.) The thought of trying to rebuild my bookmarks is nauseating. My only thought is to sign out of the browser on all devices, then sign back in and sync on the phone. Would that repopulate the main file with what's on my phone? Any other ideas?

Hey guys, thanks for the help in advance.

This problem occurred recently and it's quite a pain in the ass. I'm using Macbook Pro 14 inches with M1 Max chip. Lately when I work, I have to open quite many urls at the same time, and my mac went crazy hot because of firefox's insane cpu usage. I tried what's suggested to turn off the acceleration mode, but still, nothing changes.

Is there still anything I can do to resolve it? or I just switch to other browser?

ID/PW is not displayed automatically. "Settings" ⇒ "Privacy and Security" ⇒ The check mark for "Retain website login information and password (R)" is always missing. Even if I put a checkmark in it, when I restart Firefox, the checkmark disappears.

I have a PC operating on Win 11. just recently upgraded to the latest version of Firefox and can't find my bookmarks. not finding the help areas very helpful. how do I get them back and installed on left side of screen as I did in old version?

What would cause websites not responding. I have no malware and the cache is clean. Could it be in the properties, or whatever.

Thank you. It's very frustrating.

Recently Twitch and WarGaming, as well as other advertisers, collaborated on "Twitch drops" Somehow, Twitch is able to determine which tab is on top and being viewed by visitors to the website. It's one thing for Twitch to know I'm visiting the website, and quite another for them to determine if in fact the tab I have open is front and center. Seems to me this is a privacy issue that needs to be addressed.? (I have not yet determined if this Twitch snooping is working in private tabs yet, but I soon will)

Videos can't be played at higher playback speed Bug

On firefox, I cant play videos at higher playback speed or it'll only play audio or video will endlessly buffer. Using user-agent spoofer and changing to chrome makes it a little less worse but still the problem sustains. On Brave, the video doesnt have any effect of higher playback speed rather it'll make the video buffer and have very strong red contrast.

After updating to Windows 11, all my Firefox webpages backgrounds are colored black even after choosing a light theme which only changes bookmarks and toolbar to white. I want white background like my old Firefox ?

Why is there problem wit this conservative website ? Only because it's conservative and not leftist ?!
