Im using Windows 10 Pro 64 bit on a Asus laptop with 32GB RAM in it and a i9-9980HK @ 2.40GHz. It has a GeForce RTX 2060 graphics card in it with 6GB memory. I use it for work and need to have multiple tabs open at a time as a result. I always have at least 4 tabs and can sometimes get up to around 10. I also have Zoom running as well.

I keep seeing a ton of Firefox processes open when I look at Task Manager. Attached is a screenshot I just took with 7 tabs open. It shows 34 processes in the first clump with more open outside of that one.

I unchecked Use recommended performance settings and checked Use hardware acceleration when available but all that did is lower the amount of RAM being used by 100MB. I have 2 extensions enabled in Firefox, AdBlocker for YouTube and AdBlocker Ultimate. They have never been a problem before. This lag and massive overusage of RAM has only started in the last couple of weeks.

Anyone know why this is happening or how to reduce how much RAM Firefox is using? I like this browser and would have to have to switch to another one. Thanks in advance.

When i switch tab bar to vertical and then open another application with firefox-developer side by side with hyprland tile management system,, some button is not taking mouse click on exact location.

In the image below it is taking click on the list all tabs when i am trying to press menu

При заходе на сайте ya.ru и если на нём имеется строка с видео или поиск с алисой, то начинаются сильные фризы. Это ошибка именно в firefox 142, проверенно.

When I brought Firefox up about a week ago, it presented me with a survey, results of which were sent to Firefox developers. They asked several multiple choice questions about features, but they didn't ask a very important question: Would you use Firefox more if it used less system memory? I currently use Google Chrome for about 2/3 of my web browsing because Firefox uses up too much system memory. I would prefer to use Firefox most of the time, but can't, since it bogs down when memory usage gets too high.

The survey should have included a text input box so users could enter any comments for the developers, and the survey did NOT do that.

So, after completing the survey, I was disappointed that I couldn't comment on the most important issue I have with Firefox. I would like the Firefox dev team to try get Firefox's use of system memory down. A short while ago, I opened 4 websites in Google Chrome, then opened the exact same 4 websites in Firefox. The attached shows the memory usage of each browser.

The cursor changes from the Hand, Caret back to a normal cursor when hovering. Also sometimes the cursor disappears entirely. Moving the mouse temporarily makes it visible again. The latter is especially annoying and it occurs on most websites including even the Firefox Add-on site. Refreshing the Which suggests it is not related add-ons (at least most of them anyway).

I have a different browser with the same user.js (BetterFox) and same chrome.css. However, I was not able to replicate it there. Maybe I need to have open many dozens of tabs. No issues with my browser otherwise, performance or memory. Anybody else have this issue or can help troubleshoot and find the cause?

Current situation: I start Firefox and it starts maximized. When I move the mouse cursor to the lower edge of the screen, the taskbar should unhide but it remains hidden. To correct for this by dragging the window so it resizes (floating window) and then maximaze by pressing the maximize button on top right. Now the task bar unhides as expected.

If I drag the window so it resizes (floating window) and then maximaze by dragging it to the top edge of screen, then the taskbar again wont unhide.

I must do this every time I open a new Firefox window.

I can replicate this whenever I want.
