Browser crashes frequently and cannot handle even small web pages like google search..

## Summary The SerenityOS browser crashes frequently and is unable to handle even small, simple web pages. This makes normal browsing unreliable. --- ## My steps 1. Opening browser. 2. Visiting a small page or any searching. 3. Perform basic interactions (scrolling, clicking links, reloading, or opening a new tab) 4. Some time it is not even loading. --- ## Expected Behavior The browser should load and interact with small, normal web pages without crashing. --- ## Actual Behavior The browser crashes unexpectedly, sometimes shortly after loading the page or during basic interactions. --- ### Observations - Multiple `MM: Unable to commit 16 pages, have only 13` messages - Browser and WebContent are running when memory exhaustion occurs - CrashReporter itself also fails due to low memory - Final crash triggered by an illegal instruction in userspace ---- ## Environment - **SerenityOS build**: latest master (or specify commit) - **Architecture**: x86_64 - **Running on**: QEMU / Bare metal - **Build type**: Debug / Release --- ## Additional Notes This issue occurs even without heavy websites or multiple tabs open. Crashes happen during normal usage and make basic browsing difficult. ## Crash Report / Logs 142.002 [#0 Finalizer Task(8:8)]: UHCI Async Poll Task(4) resident:0, shared:0, virtual:0 142.002 [#0
