Hello:

Over the past few weeks I notice Firefox lagging in performance -- e.g., pages taking too long to load. Simple profiling tells me that most time seems to be going in "WebRender display list", and "DisplayList building". Sometimes, it is so slow that I have to use other browsers.

I uploaded the profile here: https://share.firefox.dev/4j6f5Mp

Any suggestions?

When browsing on Youtube it takes a long time to load and display videos. Firefox seems to be searching for a long time before finally displaying videos. I've noticed that advertisements aren't displaying before videos anymore. Sometimes when video does finally play it isn't starting at the beginning, cutting out part of the video.

I've tried clearing caches, and history.

Why does it take Firefox so long to load after an update? sometimes it will take upwards of 20 minutes. ON some occasions I have to close the browser and start it numerous times!

After the last update, your browser is lagging on youtube web, every time I press a button, it takes 5 seconds for the button to respond. Will Firefox bring fix solution for this ?

Certain webpages (which load without problem in Opera) will fully load and then immediately become blank as if it never loaded. If I hit "reload" the same thing happens, it loads and then goes blank. This is only certain webpages but here is one for example:

Again, this is not a problem in Opera. But Firefox has been my main browser for many years now, and I'd rather not switch if I don't have to.

Thank you. Malcolm Garris

This isn't a question but rather a response to the latest iteration of Firefox. Whatever your team did in this new install has made a dramatic difference in response time. I notice it most when signing in to my Yahoo email account, the delay time is down to 2 seconds between hitting Enter and the change. This is terrific since it previously took 20-30 seconds to happen. Thanks very much for your work, folks.

For about 1 month now whenever I perform a google search using the address bar I get no response. I have to close and reopen FF afew times untill it performs the search.

This occurs in my synced account in any of my Wiondows devices. Troubleshoot mode makes no difference.

I've uninstalled all 3 plugins which iI use but to no avail.

Video is not loaded on youtube, I have the whole site, but when i go to any video, I have an endless download, normal video download will be one of 30, I don't know what to do with this At the same time, such a problem is not observed in other browsers, but I want to use Firefox Please help me

I have two computers - one Windows 10 and one Windows 11 I have Firefox 135.0 installed on both of them. When I'm looking at a recipe on the website: https://www.tasteofhome.com/recipes/slow-cooker-rotisserie-style-chicken/?_cmp=slowcookernl&utm_source=email&utm_medium=newsletter&utm_campaign=&utm_audience=&_mid=754995&ehid=f2c9dc4df75a96cec74bb878e8e55ed61233365f&os_ehash=f2c9dc4df75a96cec74bb878e8e55ed61233365f&_PermHash=33bd81daea6ba3d5b9b6bfe1b1324a6a59c6cf4637a8060e34a28dd3bb62483f&tohMagStatus=NONE the new computer has a spinning circle for looking at the reviews. The old computer displays them right away. Both computers are sitting side-by-side on my desk, plugged into the same LAN, and using the same Comcast ISP connection. Also, the Edge browser on the Windows 11 computer shows the reviews right away - no spinny circle.

Hello Mozilla Community,

I’m currently using Firefox for my web design projects and facing some performance issues when testing websites built with modern frameworks. As a developer at DE IT SOLUTION where we provide website design and development services, I rely on Firefox for testing due to its robust developer tools.

However, I’ve noticed:

Firefox becomes slow when handling multiple tabs with live previews. Developer Tools sometimes lag during real-time CSS adjustments. I would love advice on:

Best practices for optimizing Firefox for web development. Recommended extensions that won’t slow down the browser. Tweaks for faster rendering of web pages during testing. I’ve explored Mozilla’s tips but would appreciate insights from this expert community. Also, if you’re interested in how UX/UI impacts web performance, you might enjoy this article from my experience: Why UX/UI Design Matters in Web Development (Sharing for learning purposes).

Thank you in advance for your suggestions!

When I restart the system after a refresh or after shutting down, Mozilla takes FOREVER to connect/load webpages. (I can get on-line immediately after a reboot using Chrome, however). It is extremely frustrating as I have to leave the system on a webpage all day long and over-night so as not to have to go through the hassle of trying to get it to connect after an absence. Even when Mozilla requests I re-start for an update, it still takes forever. what is causing this and how can I fix it? Be advised, I'm not a computer whizz so please explain in non-tech talk. Thank you, Joe

I have been using Firefox ON this desktop since Feb. 13, 2019 But used Firefox way before that on other desktops. I just saved my profile from one to another and in 2019 I got a new computer again and I never have cleaned it up. I did searches on how too but nothing on how to get rid of passwords and user names logins on websites I no longer used except for one at a time, that will take me weeks,months to clean Firefox up, and how to clean up bookmarks the same, and so on. Today I saved a copy of my profile folder and was shocked to see it is almost 2GB. It explains why some days Firefox doesn't load properly, and why getting stuff done on here is more than a feature, it is bad chore I really need to tackle this and hope you guys can help me out on getting this mess cleaned up. Thanks for your time and support.

Hi. Mozilla has been my preferred browser since it first came out and up to 3 days ago my use of it has been awesome. But 3 days ago my location started showing as if I lived in Miami instead of Oakland where I actually live. The "problem" is every time I do a search it gives me responses as if I lived in Miami... and i don't.

At the bottom of the page, it says the responses are due to my IP address, so I contacted my internet provider (Comcast) and they tell me my IP address is identified as Oakland, and told me to look else where.

So I am now looking to you. Do you have any thoughts on what the problem might be?

Thanks for any help you might offer. Be well, Joseph
