I don't know when it exactly happend but arround 3 months ago my Firefox is on the verge of dying anytime i open a new TAB it takes about a min to be funktional again which is a pain!

before that time Firefox was quick never hade these problems before! A friend of mine has the exact same problem as i do.

honestly will not read the awnser on this post but i just want to make sure its on the Board

when I click on my AOL mail in a few seconds it freezes my computer, if on chrome it works fine, had computer we dune $155 but still the same. this dose the same thing on my lap top. all other sites work fine till I click on AOL mail.......

Ever since the latest update i've noticed my firefox browser after using it for a while starts eating up all the ram until my computer freezes and needs to restart, i've heard this issue happen to others too but i am wondering if there are any ways to prevent it or will there be any updates to fix it?

I use my firefox on bazzite and have nothing else running in the background, after a while i watch the stats in my task manager and i see firefox using over 10GB of ram and climbing and have to shut it down before it freezes my pc

(can't show any screenshots because if i do then my pc would probably crash when trying to SS it while it has its problem)

Hi Mozilla team,

I’d like to report a serious issue with Firefox lately. The browser has been performing very poorly and frequently becomes “Not Responding.” In many cases, websites fail to load properly or get stuck indefinitely, even though my internet connection is working normally.

I’m experiencing these issues on the latest version of Windows 11 with the latest version of Firefox. This has become quite frustrating and significantly affects my daily browsing experience.

I hope the Firefox team can investigate these stability and website-loading issues and provide a fix soon. Firefox used to be much more reliable, but recently the overall experience has been very disappointing.

Thank you.

When I login to Fidelity site, my username is displayed one letter at a time with noticeable delays. It started about 4 weeks ago. I noticed Remote Procedure Call was active with 4% CPU. I disabled remote access. The issue went away for 3 days, but has resumed today.

Is my FireFox hacked?

I changed browser to Microsoft Edge. The problem went away.

Firefox on Android freezes completely whenever I open multiple tabs.

Steps to reproduce:

Open the Firefox app on my phone.

Open a website in one tab.

Open a second or third tab and try to switch between them or browse.

Observed result:

The browser stops responding, freezes, and fails to load or switch tabs smoothly.

Expected result:

The browser should handle opening and switching between multiple tabs without freezing or crashing.

Добрый день. Сегодня обновился у меня браузер до последней версии и перестал нормально открывать странички сайтов открывает и через время зависает почините пожалуйста скрин смотрите вот так все зависает и не отвисает

Hi everyone,

After a recent series of updates to both my mouse and Firefox, my mouse no longer scrolls within Firefox. The mouse is Logi wireless mouse. Firefox is the latest version. The mouse scrolls fine in other apps, like WhatsApp, Outlook, Word etc. but not in Firefox.

When I try to scroll in Firefox, it stutters, jumps and will continue to jump even when I stop scrolling on the mouse.

I have spoken to Logi and there is no issue with the mouse itself.

I have tried Troubleshoot and Private mode, but still the same issue, so its not an add-on or extension problem.

Is anyone else having this issue over the last couple of days, or have any ideas on how to get back to smooth scrolling?

Thank you, Graham

An 8 second delay when I open Firefox for the first time.. Once it has been opened once, it reopens immediately when required. The problem has been present since I installed Linux Mint 9 months ago, Linux Mint 22.2 then, since upgraded to 22.3 Zena. I can live with it, but it is very frustrating! I have tried the obvious things like removing extensions, but I suspect it is a "Linux" connectivity problem rather than a "Mozilla" problem.

I'm experiencing continuous screen blackouts or glitches. These are unaffected by the site I'm on and only occur for Firefox browser. When I switch a tab or click a button the browser blacks out and becomes unresponsive then comes back on after a few seconds. This happens repeatedly. Clearing the cache, running a repair, and uninstalling / reinstalling the app have had no affect on it.

This may be an old problem. In Linux, in bookmarks library, the scrollbar thumbs behave differently than in browser web pages. Even in new profile. This isn't a new issue for v157. Same behavior in any theme (any Fx themes, and / or diff 'Nix system themes).

I set scrollbars to disappear when not used or being hovered. On sites, when hover scrollbar area, they reappear. AND while pointer is over the track or thumb, it remains visible - does not reduce to an unusable width or disappear completely. As I think it should.

But in bookmarks library, the track & thumb disappear, even w/ pointer hovered, unless thumb is grabbed immediately. Even grabbing thumb & move it, then pause a fraction of second (still gripping thumb w/ L mouse button), the thumb & track STILL disappear. As long as you don't release grip (on now invisible thumb / track) they reappear when move pointer.

The bookmark library scrollbar behavior is also erratic. How long you have to grab it, when you 1st hover it. If you accidentally move pointer from folder pane, past vertical divider into bookmark pane, then left - back into folder pane, the scrollbar doesn't appear.

You have to move pointer well left of scrollbar, then approach it from the R, to make it reappear. It doesn't have any of this behavior in the browser (never has, AFAIK).

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.
