javascript - Force link to open in same window/tab -
i using google chrome extension - open link in same tab.
it's simple , says, forces links open in same window/tab. require functionality touch screen kiosk left/right swipe navigation.
the plugin works when comes links. doesn't work when search performed in 'submit' web search form. presumably because extension forcing _blank open in _top, it's ignoring forms.
how can modify extension in such way takes consideration forms, , forces these open in same tab?
i have downloaded extension , viewed code, main js seems in sametab.js file. have included below, i'm sure can modify somehow fit needs.
any appreciated.

you can try setting queryselectorall forms well. i'm pretty sure forms support target.
