Hello there.
We understand that the browser memory leak is affecting your QuickBooks Online (QBO) experience, and we appreciate the steps you've already taken, such as clearing the cache.
When your current browser handles too many tabs and extensions, it can interfere with QBO. Since it operates within your browser, accumulated memory usage can quickly overwhelm your system resources.
With this, I recommend switching to another supported, up-to-date browser to narrow down the issue and start fresh with no damaged files, tabs, or extensions that cause this memory leak.
Feel free to comment back if you still have concerns. The QuickBooks Community has your back.
