Falkon & Zoom links

Hi,

I tried to open a zoom link in Falkon in LMDE (upgraded today):
https://us06web.zoom.us/j/85392004701

Unfortunately, this starts an infinite loop of opening new tabs, that consumes lots of RAM/CPU, thus leading to a race condition and DoS :(

Also, since opening a tab in Falkon captures the mouse, it is impossible to open a terminal and kill the faulty process :( Even with my keybinding to call XKill, I had lots of troubles stopping the flood, as Falkon got respawnd every time, until I killed a few other processes (x-open/x-www-browser?).

This is probably a security issue (DoS) that should be addressed.

Regards


GM
