When the Google Chrome browser runs, the user may show a message stating that some additional tools are no longer supported or that it has been disabled or that the browser asks the user to remove additional tools.
The reason for the suspension of such additional tools is due to the American company’s dependence on a new description of the additional tools in the Chrome browser known as “Manifest V3”, and some additional tools do not meet the requirements of this new standard, not even the Manifest V2.
Operating attempt
In such cases, the user initially must try to run these additional tools with ease, by clicking on the three -point menu on the top of the right side, then moving to the “Additional tools/Additional tools” item, and then clicking on the scrolling bar at the right side in the added tool cards in order to reactivate them.
Even when activating the additional tool, it is not clear that Google tolerates the activation of the intended tools concerned.
The user can search for alternatives to the additional tools concerned, which have been disabled or even converted to the use of another browser of programs that depend on the chromium browser itself as the Google Chrome browser, and supports the additional tools “in 2” for a longer period; Because it will adopt the “Manifest in 3” standard at a later time.
A browser from a different family
But the problem of the additional tools will appear again sooner or later, so it is better for the user who suffers from this problem converting to a browser from a completely different family, such as Mozilla Firefox, which depends on the Gecko engine, and will not have to do with the Manifest modification modification.
The Firefox browser also includes countless numbers of additional tools, and it is unlikely that the additional tool that the user uses in the Chrome browser is not present in additional tools offers in the Firefox browser.
The latest version (136) of the Firefox browser provides many useful functions, such as vertical tabs arrangement in addition to the usual horizontal arrangement, in addition to modifying the side ribbon so that the reference signals, the browser record and the chat robot can be displayed in artificial intelligence.
