Firefox Community Forum

Dear Mozilla Firefox Support Team,

I have been a loyal Firefox user for many years because I have always appreciated its speed, privacy, and reliability. However, I have noticed that Firefox has become slower over time, and I am disappointed with its current performance.

The browser feels increasingly sluggish during everyday use. One of the biggest issues I experience is with YouTube, where videos often do not play as smoothly as they should. I also notice that Firefox consumes a significant amount of RAM, even when only a few tabs are open, which affects the overall performance of my computer.

I sincerely hope the Firefox team will prioritize performance optimization in upcoming updates. Many users, including me, want a browser that is fast, lightweight, responsive, and efficient with system resources. Speed and smooth performance are some of the main reasons people choose a browser, and I would love to see Firefox become the quickest browser again.

Please continue improving memory management, reduce unnecessary resource usage, and optimize YouTube and other modern websites for a smoother browsing experience.

Thank you for your hard work and for listening to user feedback. I hope future releases will focus on making Firefox faster, lighter, and more responsive.

i keep getting annoying popups from this websites saying virus detected, system error, download this antivirus etc. These are their URLs: isistelies.co.in; 37yito.isistelies.co.in They won't stop popping up! How do I block them?

Can you safely run Norton VPN (WireGuard) and Firefox VPN at the same time on the same Windows device. Is there any increased risk of routing collisions, adapter conflicts, DNS leaks, dropped connections, or other issues for using both.

When I frequently turn off my computer using the system unit's power button, meaning a quick shutdown, after several such shutdowns, when I launch the browser, I'm prompted to log in again. Bookmarks that weren't synced disappear. And I'm also logged out of all the websites I was logged into, forcing me to log in again. Cachyos Linux.

I had opened a support ticket #447010 with Mozella support and they told me that they can not help me, and sent me here. I am "dead in the water" so to speak. It appears that since Firefox downloaded update 153.0(20260715202819) I have had many issues that appear to be getting worse by the day, and now I cannot open or run my email app. I have not wrote down all the errors (sorry) but here are a couple: 431 Request Header Fields too large, the application is having trouble connecting to the server, unable to load the email from Mozella support. After the update (153.0) my bookmarks have moved to somewhere, the sign on for my email app has changed ( use to click on the firefox icon on the bottom tool bar and the sign in box for optonline.net would be there. I understand that sometimes updates (new and improved) make changes to what users have use to for years. Now is have a browser that is not functional and needs to be corrected, I trust you can help and get this sysem usable again, because right now it is not usable. I presume if and when you respond to me issues it will be at this location and not an email. Please help. Thank you

On every browser I've ever used for all of my internet using life, including THIS browser, when you hover your cursor over a link, a cartoony hand appears and the link URL appears at the bottom. Very recently, I write on 7/27/26, this no longer works on Firefox. WTF?

How can I get right click to open my selection in a new window? this option has disappeared!

When I right click to open a link in a new window, the top 2 boxes of the right click window are blank and below them is AI stuff, but no open link in a new tab/window! where did it go? How can I get the right click open in a new window back??????

It is as if Firefox has disappeared from my desktop. I click on the shortcut but nothing happens. It was working fine last night. I have tried uninstalling/reinstalling but still nothing. A window does not even appear.

I need to update my email but to do so I am asked to write a code sent to the old email. that email is not longer existing so I cannot update nor change my email any help or suggestions? I am stuck in the login loop thank you

I want to move my whole folder and to backup and move it to a new PC. But it says when moving a file called activity-stream.discovery_stream I need a permission from myself.

i have been using the old yahoo for years and now it seems they changed the layout to resemble google. it sucks. if i wanted googles layout i would use my google email. if i use this term https://mail.yahoo.com/d/settings/1 i get the old yahoo setup screen and then i have to click return to mail and the old screen stays until i either restart the pc or restart fire fox. i do not see in fire fox setting an area that lets me put in a startup term like chrome has that will restart yahoo in the view i like. being that view is still there.

the old view that i like with the blue on both sides

                                                                                  the new view with the email control tabs to the left and not all show is the right shreen shot or bottom screen shot

hello! this may not be an emergency, but im still curious. will the sports widget be updated after the world cup? i think this would be cool if after the world cup people could choose a sports they want to follow (tennis, soccer, formula-1, etc.) and the widgets will show the updates of the following sport. what will be after the world cup ends?
