This morning (08/28/25), I updated my browser to v142.0.1 (64-bit), and Facebook as well as other sites have been affected to the point that I can't even see contents now!!!!!!!

I (God forbid) opened the same sites in Edge, and there's no problem viewing them on Edge.

Is there a way that I can roll back this latest update, because I had no problems until this morning. I'm running a Win 10 Pro OS.

Firefox kept eating my RAM, running dozens of processes. I have gone into about:config and set the dom.ipc.processCount to 1 - then I restarted Firefox and found 5 processes running straightaway before even using the browser. I closed it down and have started it again and now there are 11 processes running with just one tab open. Firefox(9044) Utility(7552) JavaScript oracle Network (15912) Data Decoder (11364) GPU (18744) About pages (12536) Preloaded new tab Extensions (20544) Preallocated (16132) Preallocated (13780) Preallocated (16044)

The problem repeats on three different computers which are not infected with malware. One computer with slightly less RAM I now cant even use Firefox at all (though all other browsers work fine) because the tabs constantly crash due to the high number of processes. Is there any way to set the process limit low in a way that Firefox actually responds to?

What can i do ? Bernard Ps: si vous parlez en francais c'est mieux pour moi...

i just want to be able to add drag space to the top of my browser so i can move the window easily while it's maximized. i have been unable to find the customization section of firefox options and there is also no place on this website to speak to an actual member of support staff. this should be simple

msn.com comes in just fine on Firefox on Windows 10, 8, 7 computers. What's causing the undefeatable block on Windows 11?

Greetings, On cargurus website for example there are many filters which contain multiple checkboxes each. If I scroll down to a section and select a checkbox, the results refresh and takes me back to the top of the page. The problem is that sometimes I want to select more than one checkbox in a filter or choose checkboxes in the next filter to select a checkbox. When I search for cars I may end up selecting more than 10 filter checkboxes to get the results I want. If I have to scroll back down to where I left off each time, it takes a lot of time to run a query. This jumping to the top does not happen using Chrome, so there must be something in firefox that can be adjusted but I cannot find it. I only used Cargurus as an example, but it happens on all sites with checkboxes. Keep in mind I am not a programmer so I don't know how to add code to websites or firefox settings. Thank you, Mark Sufka

Best regards,

At the beginning of 2025, I created a private theme and installed it locally (Windows 10), consisting of a manifest.json and a GIF file. It worked perfectly. Now, on Windows 11, I'm trying to use the theme again, but when I upload the file (.zip or .xpi — via about:addons -> Install Add-on From File), I always get the message that the file is corrupted. However, if I test it temporarily under about:debugging, it works immediately without any issues.

I would really appreciate a solution! <3

If I have taken photos in past years on a particular date, I get an email from Microsoft to review them. I normally do it on my phone, but today tried it from my computer. The path is "One Drive" "Photos" "Moments" and then "On This Day." If you click on the photos that in the graphic that looks like a movie strip, a montage of the photos shows up and you can also click on one. However, in Firefox, I click on a picture and the screen goes gray, but nothing ever loads. I thought it was a Microsoft issue so used their help function. The rep and I tried it, then cleared the cache, then tried it in a private setting. We got the same result every time. Then he tried it whatever Microsoft's browser is called and it worked just fine. They said it was a problem on the Mozilla Firefox end, so I'm reporting it. Please let me know if you can help me make it work. I don't like using anything except Firefox.

My company just changed primary severs and correspondingly, our email address.I want to sync my bookmarks, tabs etc... but since my account email has changed, I can't log into Firefox because the verification code is being sent to my now disabled email. I have opened a new account with Firefox using my now current email. Is there a way to still sync my previous saves and bookmarks? I have an Account Recovery Key for my previous account with the disabled email.

When I sign in, multiple firefox open, causing my machine to run slow. I have to go to task manager, close all the firefox and start over. I usually have to do this several times before I can get signed on. Once on, the new Windows 11 seems to work well with Firefox.

I noted in the multiple firefox accounts the following Group or User Names in the Details section. Are these normal or could they be the source of my problems???
