This morning Brave suddenly began to lag in both it’s app tasks (clicking on forward and backward button, opening its menu, etc.) as well as when typing into a text field such as this one. It just began this morning (3/18/25). No new extensions were added, nor any new apps to the macOS.
I tried deleting both cookies and cache. I closed Brave and rebooting. Brave is the only app running and has just two tabs open, no animation or downloads going, yet Activity Monitor shows it using between 150% and 190% CPU. There are only 2 Brave Browser Helpers running, each consuming about 75%.
I’m running version 1.76.74 Chromium: 134.0.6998.89 (Official Build) (arm64) and it says that is the latest version.
My Computer Specs:
MacBook Pro Max M1
32GB of ram
1TB SSD
macOS 15.3.2
Any insight pertaining to the cause and/or solution would be appreciated. Thanks!
@Jimmy4Thumbs have you opened Brave’s task manager or you only relied on your OS one? In the hamburger menu you should have options to choose More Tools → Task Manager. This will have its own independent task manager with all the processes running by Brave, of which there will be quite a few. For example:
Knowing what is running higher will help determine the problem. Essentially to know if it’s an open tab, an extension, or something else.
NOTE
It may also help you to try to create a second browser profile to test on. If it has no issues, then it tells you it’s something unique to your other profile…most likely an extension.
Other thing in regards to extensions and all would be to try to open as a private window and see if it happens there.
Even though you haven’t added any new extensions, there have been updates done. Each update to the browser, extensions, or even your OS always introduces changes that can cause new types of conflicts.
@Jimmy4Thumbs okay, so that’s listing the same extension twice. It’s like it has two instances open at the same time. If so, then that might explain where it’s kind of bugging out.
When you look at that, you’ll see where it kind of tells you the identifier for the extension so you know. We’d look at this part:
In particular, it’s ihcjicgdanjaechkgeegckofjjedodee.
If you have the extension(s) installed, then you just need to go to brave://extensions/ and make sure the toggle for Developer Mode is on. Once you do that, you’ll be able to see the ID. We’ll take a look at mine as an example:
Since I don’t have your extension installed, I decided to look it up by going to Chrome Web Store and searched for the ID seen, which shows me it’s Malwarebytes
@Saoiray Yep! That was it! Malwarebytes Browser Guard 3.0.14. As soon as I disabled it in two of my three profiles, resources (CPU, RAM, etc.) all returned to normal.
Thanks so much for your help! Do you have “Buy me a Coffee” link or some other way I can thank you?
You know, I hadn’t. But because I’ve seen it mentioned before, just went ahead and set one up for the heck of it. https://buymeacoffee.com/saoiray
With us using Brave, not sure if you’re using Rewards. You could always just send BAT or whatever as well. I am set up as a Creator on my Reddit and X (Twitter) accounts and can receive tips from Uphold or to my Solana wallet.
