MS Edge crashes when user clicks a target="_blank" link in the sidepanel

[twschiller]

We're hitting a nasty bug where MS Edge crashes when the user clicks a target=_blank URL in the sidepanel:

• MS Edge: clicking a link in a sidebar mod crashes MS Edge pixiebrix/pixiebrix-extension#8206
• MS Edge MV3 crashes when clicking sidebar gear icon pixiebrix/pixiebrix-extension#7809

MS Edge crashes and on next startup, our extension is no longer installed

I'm surprised other developers haven't hit up against this? Or is there an existing bug ticket

We're currently trying to reliably intercept the clicks to use window.open or browser.tabs.create instead. However, in some cases there might be a frame embedded in the side panel. Therefore, we'd have to have a contentScript to just try to intercept link clicks for any frame that might appear within the sidepanel

Ack. We will get back after investigating this.

Appreciate the help! For others viewing this issue, here's our latest workaround for embedded iframes: pixiebrix/pixiebrix-extension#8223

@twschiller can you share a sample extension for reproducing this crash? I tried reproducing the crash using the extension published on the Chrome Web Store but couldn't.

Hi @rishikramena-ms, thanks for investigating. Here's a repository with a minimal reproduction: https://github.com/pixiebrix/msedge-crash-repro.

• Loom of MS Edge crashing
• I'm on Version 124.0.2478.51 (Official build) (arm64) on an M1 Mac

Let me know if there's any other information I can provide!

I think the bug is related to the sidebar being tab-specific. It wasn't crashing for me when using a global sidebar

It might also be related to MS Edge's behavior of closing the tab-specific sidebar when opening a new tab: w3c/webextensions#588

I tried reproducing the crash using the extension published on the Chrome Web Store but couldn't.

We've added a mitigation: https://github.com/pixiebrix/pixiebrix-extension/blob/44a3b1a8b947ec82af349779c8e4baa4435db0ac/src/utils/openAllLinksInPopups.ts#L38-L38

And are also currently working on a mitigation for embedded frames using a content script: pixiebrix/pixiebrix-extension#8223
