The Bugbug bot thinks this bug should belong to the 'WebExtensions::Untriaged' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Hello,

I could not reproduce the issue on the latest Nightly (127.0a1/20240428214249), Beta (126.0b6/20240426091720) and Release (125.0.2/20240419144423) under Windows 10 x64 and Ubuntu 22.04 LTS.

Using the attached HTML file, I dragged and dropped it over the browser window to open it. Firefox did not freeze nor did the tab crash.

I also used the SingleFile add-on to download my own copy of the page which I proceeded to also drag and drop over the browser window, with the same results as above – no freeze and no tab crash.

Also, would you be able to check if the issue reproduces in Troubleshoot Mode (which disables add-ons)? Just to check if the SingleFile add-on might be causing the freezes/crashes. Thank you !

Could you visit about:crashes and share the crash ID of the crash?

I also tried reproducing this issue using the latest Nightly 128.0a1 on macOS 13, but I didn't encounter any crash. In the meantime, based on the last provided crash ID, I'm moving this to Core > DOM: HTML Parser to allow our engineers to take a closer look at this issue.

Hi quadronom,

unfortunately I also was not able to reproduce this issue (MacOS, current Nightly and Release 125.0.3). Do you have any preferences set in a non-default way? Could you try and create a new browser profile and check if the issue persists?

I tried it again this week at the same page (did another singe-file save) and everything worked fine. Seems like a one-off hiccup. I'll report back if it ever happens again.
