![]() ![]() There are other browser extension vulnerabilities described in Tavis Ormandy's blog post that Bitwarden's extension is not affected by (due to deliberate design choices made by Bitwarden to enhance browser extension security), but leaking of autofilled credentials using XSS and hidden input forms is something that Bitwarden users should be aware of. For a demo, create a dummy login item for the website domain, then click this link. However, what many users don't realize is that some of the same attack vectors (specifically, password sniffing using hidden form elements) also affect on-demand autofill (by clicking the vault itme or using the Ctrl+Shift+L shortcut). This creates a lot of exposure to XSS threats. Coupled with the default URI match detection rule (Base Domain) means that Bitwarden will autofill on every page that has a base domain matching one of your vault entries. What is disabled by default is "Autofill on page load", which automatically autofills any webpage that has a matching URI. The Bitwarden browser extension has autofill disabled by default. It's actually a little more subtle than that. Install them both, configure them securely, use the extension for browsing, and use the desktop app when making changes. For either app you want good settings like a short timeout before locking or logging out, requiring good authentication to unlock, and require your master password on restart.īottom line is that - although 95% of your vault use will be via the browser extension - this is not an either-or decision. In terms of the inherent security of your vault contents, there is no real difference. Just give me another damn window to edit the vault entry while I work with the website in the original browser window. I find the browser or the extensions "pop out" pane annoying. I also strongly prefer the desktop app whenever I am changing the vault. Using the browser extension adds unnecessary friction because of the extraneous presence of the browser. I have some secrets that I need to use outside of any browser. You can configure any Bitwarden client to clear the clipboard after a few seconds, but autofill by the browser extension closes that window entirely. Since any app can read the clipboard, there is a risk of accidental exposure to other apps on your device. It also avoids using the system clipboard when you autofill. It effectively acts as a copilot for your browsing. Your browser extension will balk when you try to autofill. Attackers may entice you to click a lookalike link like and then present a totally real looking login page. Previously setIcon would skip in private mode.The browser extension is more secure for usage when you are web browsing, because it double checks you are entering credentials into a known website. Calling refreshBadge without this would update the badge on all windows (normal and private ones) Previously setIcon would skip in private mode. In private mode the main.background bootstrap-method passes in the windowId Only pass on the windowId if defined and within Firefox This resorted in the badge not showing a match count in another window.Įnsure in MV3 that all listener pass on the windowId if present. In MV2 the `windowId` isn't passed into updateBage and fails to retrieve the correct tab to update. * Only use windowId to retrieve tab when defined * Remove lock icon when unlocking on all windows * Only try to retrieve tab in unlocked state Iterating over all active tabs like in 2022.10.1 was missing:Ĭreate clearBadgeText function to take care of it. When the vault is locked or the user logs out, all open windows/tabs need to be updated No longer pass in tab and windowId to setLoggedOut and setLocked * Force update of badge icon and text on all windows ![]()
