Ran into an interesting bug with Firefox since installing the macOS26 Dev beta. Whenever I use command space to bring up spotlight, Firefox become unresponsive, the beach ball will spin. It will only happen if Firefox is in focus when I use spotlight, and only if I am signed into Firefox sync.

I am not sure of a way to help replicate this issue as it seems to only happen when signed with Sync, but I would be happy to provide additional if I can.

When I try to go to costco.ca I get a connectivity error saying site cannot redirect properly. This site works with IE or other browsers.

The page isn’t redirecting properly

Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

   This problem can sometimes be caused by disabling or refusing to accept cookies.

I updated Firefox this morning to 139.0.4 on my Mac and now the '+' sign to add a new tab no longer appears on the tab bar. I can still add new tabs with Command T however.

Any suggestions on how to restore the '+' sign?

Thanks Dan

I am running Firefox on Linux. Desktop environment is KDE. Compositor is Wayland. I have a 11th Gen Intel Tiger lake Core i3 with integrated Intel UHD Graphics GPU. I do not have a eGPU or any other GPU apart from the integrated Intel UHD Graphics GPU. Intel drivers are installed and are being used. Please see the details given below from about:support for more details. What I have observed that Hardware acceleration, specifically WEBRENDER_COMPOSITOR, WEBRENDER_SHADER_CACHE and WEBRENDER_DCOMP_PRESENT are disabled. The details are given below.

I have enabled the force hardware acceleration too by setting the property media.hardware-video-decoding.force-enabled to true. But still the above three hardware acceleration are still not available.

How can I get these enabled?

Once I visit any web site that uses HTTPS there is approximately a 90% chance it'll take seconds or even minutes to secure the connection. This never happens on other browsers as they load such pages instantaneously.

I already cleaned my data up and removed the extensions, both suspected and innocent bystanders, to no avail.

As stated in the title, I'm using Firefox 139.0.1 x64 on Windows 11 (24H2, build 26100.4061). This started happening after an automatic Firefox update, I never changed anything in my system configuration.

So I just noticed after downloading the new update to Firefox, version 139.0.1 that something new came up in my task manager called Crashhelper. Never seen this before. Closed it down and it seemed to have no issues shutting down at least. I haven't had Firefox crash in recent months, so I'm assuming that this cropping up might be a glitch of some kind? I looked this up to see if anyone else had this issue, and it seems someone on Reddit did encounter this, on Linux, and another on Windows also seems to have run into it. How do we stop this from coming up whenever we start up the browser?

Hi, I have a large number of tabs and also have pinned tabs. When I click a link outside of Firefox (FF is my default browser) it always opens them at the end of my tabs (on the far right). I would prefer that the newly opened links open at the beginning of my tabs (the far left) but just after my pinned tabs. Is there a was to do this?

Thanks!

I am sitting in hospital with a weird problem. The connection is open and thus not secure. I have successfully connected my 2 android devices, however my Windows Asus laptop is being barred by firefox. I only run firefox. It is a dead end because firefox refuses to allow me to access the net at all. So now I have to get my wife to go and download chrome and see whether that will work. Why can I not override as u understand the risks I also use Norton 360 with its VPN.

I keep getting notifications, supposedly from Mozilla and/or Microsoft on lower right of my screen, telling me the system is infected. How do i determine if these messages are valid, or a scam ? Turned computer off and back on--messages keep popping up.

Hi. I'm asking this question because I'm not quite sure how to describe this issue through a Google search. Recently, I've noticed that whenever I click and drag anything, an icon will pop up while I'm doing so. Attached is an example, I click-and-dragged on the "Learn More" hyperlink off to the right.

Is there any way to disable the icon that pops up? It bothers me and seems to slow things down, which isn't ideal. I'm not the most well-versed when it comes to Firefox's more advanced settings (the options in about:config and whatnot) so I wouldn't know where to start.

Okay, i have been using librewolf for awhile now since i got my desktop fully built. today i went to go search something related to my phone and instead of using duckduckgo it automatically used Google. i do not want this and have no idea how to fix it

I need to recover a `.jsonlz4` file to restore a Firefox session with 8 active instances, as the "Restore Session" feature only opened 5 due to the `browser.sessionstore.max_windows_undo` setting being capped at 5, and the full original `.jsonlz4` file is now missing.

In the`firefox/Crash Reports` directory, there are numerous files I can’t interpret, can I retrieve my session data via telemetry or other methods using this crash information. I’m using Linux Mint with Flatpak Firefox, and I also have crash logs containing a "last crash" text file and a string of numbers, could these be useful for getting back my session?

I updated firefox, and all my addons and sign ins are gone now. Search history and tabs remained intact. It also created a folder on my desktop, but I'm not sure how do I "extract" my old data from it.

When logging in to a website that I use many times every day all day, all of a sudden I log on and all I get is a blank white screen. I have tried clearing everything, restarting Firefox, removing Firefox and re-installing it, rebooting the computer, starting Firefox in the safe mode but no change. The same problem shows up on three different computers on two different networks with two different ISPs. The website opens normally on Edge and Chrome. I would prefer to be able to use Firefox. Using version 139.0.4 (64-bit) on all three computers. I would really appreciate any help that is available.
