Diễn đàn hỗ trợ Firefox

I use several browsers and when it comes to functionality I consider FFox to be the best however with 1 major drawback - it's speed / lag issues which is why I stopped using it as my primary browser and only as secondary one

I can have 2 different Chromium based browsers open simultaneously and while this impacts the performance somewhat if I open Firefox and another browser responsiveness grinds to a halt (sometimes even crashes)

Even just starting Firefox by itself takes 5x as long as other browsers

So I'm wondering is Firefox just more resource intensive or is there something wrong with my setup?

The main difference between my Firefox install and my other browsers is the number of Bookmarks (10000s) due to me having it installed for much longer so is it possible for a large number of Bookmarks to slow the browser down even when not open ?

Other possible causes I read elsewhere are 'Cookies and site data' (currently around 50mb)

I clear the 'Temporary cached files' & 'Browsing history' on regular basis so they shouldn't be an issue

The add-ons I have installed are NoScript , Ublock Origin & Firefox Color

In regards to troubleshooting is it possible to install a 2nd install on the same system simultaneously without overwriting the current one ?

Thanks

According to Mozilla and all other online instructions for changing Firefox wallpaper, one must click on the Settings icon (pinwheel) in the upper right corner of a new tab. There is no such icon anywhere on the new tab screen. There is no wallpaper to select under the Settings menu (three dashes) in the top right hand corner. I have the latest version of Firefox. What version are these instructions for? And how does one change the Firefox wallpaper? Firefox is my default browser in Ubuntu 2204 LTS.

One of the add-ons I use has been permanently disabled. However, the email that the developer received says "Users who have previously installed your add-on will be able to continue using it." Why can't I use it?

Recently Mozilla had the brilliant idea of doing something they've done before...obscuring the URL/Address from the user. So now when you search the URL bar never shows the address your query is sent to because "usr 2 stoopid, need dum." Mocking aside how do you disable this trash. I just came back to Firefox being fed up with Mozilla pulling idiotic pointless weekly UI/Behavior rug pulls like this and...well some things never change.

Don't know how to describe the issue. I leave the computer on all night. In the morning, when I move the mouse to activate the screen, there is a large, 3-panel image with links to various websites. Today's panels are titled "Daily Wonder," "Hats Off to the Class of '25," and "Markets." A click on any of these panels takes me to a website. No idea how these panels are produced or by whom. If I try to take a screenshot, the images disappear and my normal home screen is shown. I do not recognize anything in the Task Manager that might explain this. Not sure if this is a Windows issue or a Firefox issue. Perhaps another user can ask me questions that will lead to more information.

Windows 10 version 22H2, OS Build 19045.5854.

Some of my shortcuts were missing on Firefox when I started my laptop this morning. I tried restarting my computer but that didn't help. I really don't know what topic fits best. I am not at all tech savvy when it come to computers.

Hello, when opening a video on YouTube in full-screen mode, the horizontal scroll bar becomes visible if you start moving the mouse cursor or scrolling. This doesn't happen in other Chromium-based browsers, where the scroll bar is always hidden (in full-screen mode). I tried deleting all browser data, but it didn't change the situation, and I couldn't find any solutions on the forums either. This looks very unattractive and ruins the video immersion. I hope you can help me resolve this issue or release an update that fixes it.

Thank you!

How does one get rid of things like this: ad.doubleclick.net

This is one of several plagues on my PC. Another is googleadservices.com. They appear, hijack searches, making it almost unusable, and I can not locate the app, program, or add on anywhere.
