Agree with him and You need at least 32Gigs of ram and decent CPU and any decent GPU.
However, I don't know which browser can have 100 tabs open and let all videos play. Because, Browser are made to save resources if the tabs are not active they stop in background. So you might have to check firefox as it have too much customisation available.
Open this in Firefox:
- Increase the Number of Content Processes:
- In Firefox, type about:config in the address bar and hit Enter.
- Accept the risk and proceed.
- Search for dom.ipc.processCount.
- Double-click on it and increase the value. Firefox uses a process-per-tab model, so increasing this number allows more tabs to run simultaneously.
- Keep in mind that increasing this value can consume more memory and CPU resources.
- Adjust Browser Preferences:
- Type about
references in the address bar.
- Scroll down to the "Performance" section.
- Uncheck "Use recommended performance settings."
- Adjust "Content process limit" to a higher value. This setting controls how many content processes Firefox can use at maximum.
- Again, keep in mind that this can increase resource usage.
Hopefully, It helps.
