When checking out the new features the ' Learn More' link under Tab Groups directs to the article explaining Pinned Tabs, there is no way to get to the explanation about Tab Groups

http://www.portal.lincare.com. When I typed that www. and it shows firefox cannot open it for me to order the supplies for my CPAP.

I am having trouble getting yahoo.com to appear on Firefox. It worked perfectly for many years but on my current Firefox browser, www.yahoo.com does not work. The page will appear for seconds and disappear. How can this be fixed? Do I need to download a newer version of Firefox?

Firefox updated its version on my iMac desktop two days ago and all my bookmarks are gone. There's a message at the top that says: "For quick access, place your bookmarks here on the bookmarks toolbar. Manage bookmarks..."

All my bookmarks are gone as if they were never there. I have a My Passport Backup hard-drive but I don't know where I can find them and restore them.

Hello Mozilla Team,

I am facing a glitch that is as hilarious as it is frustrating. Firefox has decided that my professional life must permanently take place under a massive, virtual Apple Park Rainbow. And I cannot turn it off.

The Tragic Backstory: This is the system-level macOS camera background. Usually, you disable it via the green camera icon ("pill") in the macOS menu bar. However, the moment Firefox accesses my FaceTime HD camera, the macOS camera menu completely freezes. It becomes unclickable.

What I’ve tried so far (and failed):

   Google Meet says "No effects applied". It has no idea the rainbow is even there.

   I used "Refresh Firefox" to completely wipe my profile. The rainbow survived.

   I forcefully revoked camera permissions via Terminal (tccutil reset Camera org.mozilla.firefox). Upon granting permission again, the rainbow immediately returned from the dead.

   Restarted the Mac multiple times. No change.

   Even opening the native FaceTime app to override the toggle failed, because Firefox seems to have locked the video pipeline down.

It seems Firefox is caching or hard-locking the macOS video effect stream and won't release it, while simultaneously breaking the OS-level menu bar toggle.

I love rainbows, but my clients during business calls are starting to wonder about my sanity. How do I force Firefox to drop this video stream and let me return to reality?

I'm trying to find a solution for having all tabs open across devices. Currently, my desktop has about 50 open tabs that I access regularly. Today, I installed Firefox on my laptop, signed in and initiated syncing. All bookmarks came over, everything looks great, except that none of my open tabs from the desktop browser show on my laptop.

I would like to have identical tabs open across devices. Is there a way to configure this where a new computer being logged in automatically receives all open tabs from the initial device and then tabs automatically sync based on whatever is opened/closed on either device after the initial tabs are identically synced?

Getting around 20ms for DNS lookups so thats not the issue. Why do I see Error Code: NS_ERROR_OFFLINE maybe once every several days when this Firefox has never been in offline mode and never will be? Env is MacOS 26.5.2 with current Firefox installed.

Hi, My browser won't save the open tabs. I lost my tabs multiple times now, I don't even bother opening them back up now, but it's annoying. I have activated ( and disabled/enabled ) the setting to open previously open tabs on startup.

What can I do ? thanks

When a link from outside Firefox opens the desktop browser, it displays the default home page but does not continue on to the URL specified in the link. This is new for me in V 152.0.6 (aarch64) . Mac OS 26.5.2 (25F84)

Hello community,

I've been moved to MacOS at work and since then, Firefox will not always restore my pinned sites when I start it the next day.

Here is what I do:

1. Right click a tab, select "Pin Tab"
2. Go about my day
3. At the end of the day, I close Firefox by using command Q and shutdown my Mac
4. The next day, I start Firefox and most of the time, my pins are gone

I did not have this issue on Windows Firefox. I am using MacOS 26.5.2 and Firefox 152.0.4 Firefox says "Your browser is being managed by your organization" in settings. It is a link that can be clicked and the only active policy showing there is "DisableAppUpdate" which I assume is because we have our own tool to manage software updates.

Any idea what could cause my pinned tabs to disappear? I did not really customize the settings so far, I do NOT clear browsing data when exiting FF and the startup option "Open previous windows and tabs" is NOT selected. I have Ecosia and 1Password as plugins.

Any help appreciated, thank you.

Hello there,

I’m experiencing high memory and CPU usage in Firefox, which is affecting my computer’s performance. One issue appears to be that “FirefoxCP Isolated Web Content” continues running even when tabs are inactive, contributing to increased resource usage.

Other browsers, such as Microsoft Edge, reduce memory and energy consumption by putting inactive tabs into sleep mode after a period of inactivity. I would prefer to continue using Firefox as my default browser, but I need a way to manage this level of resource usage.

Could you please advise whether Firefox offers a comparable setting, workaround, or planned improvement to reduce CPU and memory usage from inactive tabs?

Thanks for your help!
