Firefox 144.0 on a W11 PC with all updates.

Firefox is running multiple (10-13) windows with 5-10 tabs each. Even if all Firefox windows are minimised and not being used, memory usage goes up all the time. It is currently, according to Task Manager, using over 5 GB of 32 GB of available memory. CPU is sitting at ~4%. Individual tabs, like Youtube watching CNN suddenly freeze and are no langer accessible and can't be unfrozen by anything I have tried. Even the mouse pointer is not displayed inside this tab I need to restart the entire PC several times a day only to have Firefox usable. I have turned off efficiency mode, but this did not change anything. I'll include a system snapshot with msinfo

Any ideas?

I cannot get into the "Directv" url with firefox. i can on my Iphone. Beloiw is the error message i get.

I had to wipe clean my iMac today due to some access issue. Everything was gone !!! I had to re-install Firefox as the default browser. Now I want MarketWatch to open on Firefox every time I open the Firefox browser. Please send step-by-step instruction to this 82 yrs old lady user.

Also, I had Mozilla VPN. Please show me how to re-install/download/put back this service so that I can park it on the tool bar and choose to use it at will.

Please keep your instruction very human friendly. I don't comprehend well the "digital lingo".

Thank you for your understanding.

In Settings I have "Save files to" set to Desktop. Under Applications, I have PDF Files set to "Save File." If I download any other type of file, it is saved to the Desktop, as instructed. However, when I open Firefox, the Save dialog shows PDF files will be saved to Downloads. If I change it to Desktop, the file will be saved to the Desktop. Other types of file, as mentioned above, show Desktop as the default in the Save dialog. Once I set Desktop for a PDF file, it will be remembered until I close and reopen Firefox. It will then switch back to the Downloads folder, but again, only for PDF files. Why? This is something that has stated happening sometime over the last couple of months.

Windows 10 Pro 22H2, October 2025 patches installed. Firefox v144.0.2

We have two Windows desktop computers. One still runs Windows 10 because it does not have the requirements Microsoft set for a Windows 11 upgrade. Recently Windows 10 was reinstalled on the Windows 10 computer, choosing the option to remove apps and settings. Firefox was reinstalled. It started without problem and continues OK. However there is a problem.

Before reinstalling W10, I had copied the Firefox Profile folder to a USB drive. More specifically, I have a copy of Roaming > Mozilla > Firefox > Profiles. Prior to copying the Profiles folder from the USB to the computer, I reread a couple of web pages, including Mozilla, about transferring Profiles. At that point I realized that I may have made a mistake. The web pages stressed that Firefox should not be running when the Profiles folder copying is being done. I’m pretty certain that I had not shut Firefox down. So I am writing this in hopes that someone will be able to tell me how I can replace the current Profiles folder with the folder that is saved on the USB. What follows is some information that I hope can be helpful. On the USB: The Profiles folder contains two subfolders. Each subfolder’s name ends with .default-thirteen digits, the first six digits being identical. The “Date modified” on one folder is a little more than a week old; the other is over 5 years old. On the W10 computer: In the Roaming > Mozilla > Firefox > Profiles folder, there are 4 subfolders: 1st. ~ .default-13 digits starting with 1597077, 695 Mb 2nd.~.default- 13 digits starting with the same1597077, 78 Mb 3rd.~.default-release, 130 Mb 4th.~.default-release, 90 Mb All “Date modified” are very recent, including one date today

So I’m hoping that someone will read this to be able to help me bring Firefox back to what it was before the W10 was reinstalled.

Mozilla needs to come up with a permanent solution to this issue. I know that Google probably started it by somehow changing YouTube, but Mozilla needs to react and come up with a solution.

Having an issue that happeened after updating to Sequoia 15.7.2, when launching Firefox, it opens a new tab, but nothing loads.

Profiles don't load, I'm unable to search anything, unable to even pull up settings.

Have tried reinstalling, clearing NVRAM, deleting profiles in finder.

Hello,

In the DevToolbox, the “Copy all as HAR” and “Create file...” functions are not working. It seems that in both cases, only empty space is placed in the clipboard and in the file (this has been happening since the last update).

Thank you in advance.

I went to Wirercutter from the NY Times, tried to search and got the result "HTTP header is larger than 10240 bytes." I performed the same action with Chrome on the same machine with no problems. I am on Firefox 140.4.0.esr running on a Slackware64/15 machine.

have no idea what this topic falls under but getting the update browser error code 99,999 again after restarting the damn computer when it just froze while I went out for 15mins I am updated so have no clue what to do

wish sending a question or replying to the email was easy but even that is b/s also this deny person claims bug fixed but obviously not
