Hello 🙂
The tab crashing is happening across multiple social media sites. One commonality in error logs pertaining to these sites is zstd. Take note of What's new in FireFox 126, it mentions -
Firefox now supports Content-encoding: zstd (zstandard compression). This is an alternative to broti and gzip compression for web content, and can provide higher compression levels for the same CPU used, or conversely lower server CPU use to get the same compression. This is heavily used on sites such as Facebook.
Here are the error logs, I got while trying to access VKontakte (website loads in full; tab crashes almost instantly) while in case of Facebook & Instagram (website never loads; tab crashes instantly) -

The tab crashing and corresponding error logs are pretty consistent. Happens everytime, the social media sites are accessed. The problem persists even in Troubleshoot Mode of FireFox, the one where extensions, themes, and custom settings are temporarily disabled.
The aforementioned sites are perfectly usable on Palemoon, SeaMonkey, Yandex, Falkon, Otter and Vivaldi.
