User Reviews
When you install this addon, you may click the ellipses, then click the addons tab, then click on this "Mobile Fullscreen" tab.
Finally, you may enter the fullscreen, and by means of this addon add such functionality to Firefox on Android, whether on phone or on tablet (ie. Boox Tab Mini C), where such functionality was not available before.
And this addon does so without hassle, and does exactly as it does. I may use this on the comipo app website with my Boox Tab Mini C, which has suffered such lack of functionality, and I may enjoy the light novel or manga, without such hindrances that which decrease the screen area, such as the URL display; and I may see the material to it's fullest resolution, that is, it's largest size that can be displayed, and by this I am benefitted.

Is Mobile Fullscreen Overlay Safe?
Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
Mobile Fullscreen Overlay requires a few sensitive permissions. Exercise caution before installing.
Risk impact analysis details
- Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.
- High ******* ******* **** *** ****** ***** *** ***** ** ******* **** ********* ********* ** * *********** *****
Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.
Mobile Fullscreen Overlay is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
