User Reviews

Users repeatedly praise Load timer for accuracy, reliability and a clear, detailed breakdown of page-load costs, calling it easy to read and useful for developers. The most mentioned drawbacks are display and visibility preferences (desire for a larger or always-visible timer) and occasional reports that the add-on doesn’t show expected info or fails to work for some users.
Pros
  • Accurate and reliable page-load timing (good for benchmarking)
  • Provides a detailed breakdown of what consumed load time
  • Simple, easy-to-read interface; generally works well
  • Valued by web developers for performance analysis
Cons
  • Display/visibility/customization concerns — users want a larger or always-visible timer (rather than having to click)
  • A few reports of the add-on not showing expected info or failing to work for some users

Is Load timer 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.

Load timer 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.

Load timer has earned a fairly good reputation and likely can be trusted.
