What happened?

Hello and thanks for the project.

I have 1800 opened tabs and decided to close them in one click using "Right click on a tab > Close multiple tabs > Close other tabs". Once I click on this option, browser becomes completely unresponsive for 13 minutes and only then it has finished.

Although, I'm running on a AMD Ryzen 5 7530U with Radeon Graphics (12) @ 4.547GHz and had at least 5Gib of unused RAM.

On firefox on 5k tabs the browser becomes unresponsive for a relatively short amount of time and then all tabs are closed properly.

Version

1.11.1b (Firefox 137.0) (64-bit)

I'm also facing this, trying to close 2.297 tabs and the browser just freezes, I tried force closing it but it open them all again on the next start, I'll try opening a new window and then closing the current one to solve this, but the problem is still there.
