1515077 - Extension port disconnected when a tab switched to or from the Responsive Design Mode

Status: VERIFIED FIXED

(WebExtensions :: General, enhancement)

Description

[Luca Greco [:rpl] [:luca] [:lgreco]]

When a Firefox tab is switched to (or from) the Responsive Design Mode, then the extension port related to that tab is being disconnected (as in "the port API object fired the onDisconnect event").

This issue is also tracked on the "Redux DevTools Extension" github repo's issues:
- https://github.com/zalmoxisus/redux-devtools-extension/issues/421

(as a side note: the behavior mentioned in https://github.com/zalmoxisus/redux-devtools-extension/issues/421#issuecomment-441448097 is the one that Bug 1394841 fixed, but the extension is still experiencing issues on tabs switched to the Responsive Design Mode because the extension port that is connecting the extension's content script and background page is being disconnected when the tab switches back and forth the Responsive Design Mode).
