The MetaMask browser extension is extremely slow and unresponsive when used in Mozilla Firefox. Actions such as opening the wallet, switching networks, approving transactions, or interacting with dApps take a long time or freeze temporarily. This issue occurs only in Firefox. MetaMask works smoothly and as expected on other browsers (for example, Chromium-based browsers) and all other websites and browser extensions load and function normally in Firefox. This suggests the problem is specific to the MetaMask add-on behavior within Firefox rather than general browser performance. Impact: Delayed transaction approvals Lag while opening the extension Poor user experience when interacting with dApps Productivity impact when using Web3 applications
