I suggest to modify embedding Youtube, Twitter/X as links only w/o preview, people can post a screenshot, bcoz the preview spikes up the webpage size & RAM required.
Old & today's student laptops have 3-4 GB RAM only.
1 single webpage load immediately bumps up the RAM by 300-600 MB, even i wonder why.
And there could be many forums, reference sites, social media, etc opened.
So the RAM usage knocks the ceiling limit & the entire browser crashes.
The pages will be restored only if the option to continue where we left is enabled. Sometime that doesn't work, so it is better to log into browser with session recorded of all windows & tabs, like login on Google Chrome by Google account.
But this doesn't solve the RAM crash issue & more RAM cannot be added to laptop, nor purchasing costlier laptop just for forums is solution.
