Yeah I am aware if this warning.
This is is unavoidable now because the browser is entirely on event emitter and event listeners to ensure IPC between main and renderer process.
I haven't increased the limit manually as I'm looking on any alternative ways to achieve IPC rather than the events.

If you had any alternate ways then please suggest here it will be helpful for the further development of this browser.

@Rajaniraiyn may be this usage of node-ipc can be source of inspiration: https://github.com/thanhlmm/electron-multiple-tabs

Thank you @raphael10-collab ill have a look into it

@raphael10-collab Due to some other projects I couldn't have time to implement a different approach. if you saw anything effective, please open a pull request
