Firefox 38 will report braking extensions

Mozilla plans to integrate extension notifications in Firefox that slow down your browser, much like it does in Internet Explorer. The feature has already appeared in the alpha version of Nightly , and if everything goes well, it will move to a stable release of Firefox 38.



It works as follows. If the extension exceeds the set limit of consumed resources, a warning appears with three options: disable the extension, ignore this time or ignore permanently.

So far, the function has not matured to be added to the final release. Observers say that it generates too many warnings, constantly “swears” on Adblock Plus and Multi Links, among others.

Apparently, in the settings it is not even possible to completely disable the notification function, you can only add to the list of “constantly ignored” extensions.



In addition to it, the settings allow you to set the check interval ( browser.addon-watch.interval ) and the maximum percentage limit, after which notifications are displayed ( browser.addon-watch.percentage-limit ). The percentage limit probably means the CPU utilization level, although this is not known exactly.

In any case, if you never want to see such notifications, you can set some very large value for browser.addon-watch.percentage-limit , for example, 25.
