Fóram Tacaíochta Firefox

When I use firefox, it gets slower and slower over time to the point where it's a chore just to type. And this is on a recent MacBook pro. Everything else is fast. But Firefox gets unusable. The UI should not be a bottleneck like this.

Retarting speeds it up for a while, but then it gets slow again in a few hours.

Is there some kind of profiling I can run that I can use for filing a bug report?

In Email, with every other click on a mail item, I get the message "Firefox is not responding." After 15-20 seconds the mail continues, but the same thing happens again, and again. Checking the mail is nerve wrecking.

About a month ago, I started having a problem where all pages on YouTube randomly stop loading. It does this with no rhyme or reason and usually for around a minute at a time. It just hangs until it abruptly starts working again. Occasionally (like if I try to log out while this is happening), it will give me an error saying I'm "offline", even though I am most definitely not offline. During this time, all other websites (Google, Wikipedia, Hulu, etc) work fine, so I know it's not my Internet. Other than that, it doesn't give me any errors.

I am using a MSI laptop on Windows 10. Oddly enough, YouTube loads properly in incognito mode and in Windows Edge, but clearing my cache and cookies, disabling my extensions, and updating Firefox to the latest version didn't solve the problem. I even enabled each of my extensions separately in incognito mode while YouTube wasn't loading in a normal window, and each time YouTube loaded properly in the private window while simultaneously not loading in the normal one, so I know none of my extensions are causing the problem. Restarting my computer also didn't do anything. This problem persists when logged in or out of YouTube, no matter the account.

I reported this issue to YouTube back on December 29, but it hasn't been fixed. I also made a post on the YouTube Community a few days ago, but I didn't get any helpful answers. Any help would be appreciated!

Hi, since the last update, Firefox is taking a huge amount of memory and slowing everything else on my PC right down. Right now this support tab is the only webpage I have open, yet you can see in the screenshot there are 31 Firefox processes running, and over 1G of memory being taken. I've followed all the help threads and taken the steps in them - it's made no difference. Please can you help me find a way to tame Firefox. Also - I'm really not an IT expert at all so please can you tell me in very simple language :)

For the last two days and multiple times loading the firefox browser, it has taken about five minutes for the browser to load on our Dell Inspiron desktop, running Windows 11. Nothing happens for about one minute, then the spinning blue circle appears, then firefox starts to load, then the screen goes back to the desktop, then a black screen appears, then some white rectangles start to appear across the top of the screen, then the screen goes back to desktop, then back to the black and white top-of-browser window that is still trying to load, and then finally after the five minutes, our home page loads. However, clicking on a bookmarked website, or typing in a website in the address bar results in a 2-3 minute wait for that site to load. And this happens time after time with the computer still on, and also startup after startup. If this should continue for a few more days, we will start using Google Chrome or Microsoft Edge, and also cancel our subscription to Mozilla VPN. This cannot continue!

My laptop set-up is practically identical to that of my PC, but the latter doesn't exhibit the same malfunction.

I've tried anything I could, including reinstalling the browser, removing all of my bookmarks (about 10,000) and addressing extensions (Decentraleyes, Default Bookmark Folder, Disable Tab Detach, Flagfox, I don't care about cookies, Keepa, Notifier for Gmail, Privacy Badger, To Google Translate, uBlock Origin, Undo Close Tab, Video DownloadHelper and Youtube's Annotations No More), but not even safe mode improved the situation in the least. Windows Defender also hasn't detected any malware and my web surfing habits are as safe as it gets.

The only deeper data I could gather is that the problem manifests with a progressive, rapid surge in CPU and RAM usage; the former, for example, is saturated to its total 16 GB in a matter of about 20 seconds.

My laptop is a Dell Inspiron 7586 with Windows 11 64 bit; Firefox version is the latest, 100.0, and, by the way, none of the recent updates has improved the situation.

Thanks to anyone who might come up with an educated guess!
