Hello. I have a problem with firefox lagging on high end pc, these are my specs for context: cpu - ryzen 7 9800x3d gpu - rtx 5070 ram 32 gb ddr5 6000mhz motherboard - msi b850 wifi 6e

i have a folder of bookmarks called "social media". When i want to check every website there (for example: telegram, discord, whatsapp), i start manually opening them up, so i hit the folder, click the needed icon, open new tab, repeat everything. And the moment i turn on 2 tabs like that, everything starts lagging. I don't think that my pc is the problem, because it is not even half a year old + it has good specs. Maybe there is a setting that i accidentally turned off/need to turn on to remove this problem? I love firefox, and i am using it for a while now, but now i am thinking about switching browsers because of this constant lag that happens. With all due respect, Emin.

P.S. i know that you can open all of the bookmarks right clicking the bookmark folder and then pressing "open all bookmarks", but most of the times i don't need to open all of the bookmarks, that's why i open everything as i said earlier.

that was my fault, when i was setting up firefox i turned off the setting in performance called "use recommended performance settings". You will not have that problem because it is turned on by default. If it is ok delete my question please
