Dr.Web LinkChecker 2.5.9 Rated 5 out of 5 stars
1st off, I have No affiliation with Dr.Web Company.....
The LinkChecker is a valuable tool for the user to quickly check any links B4 opening it in the same or another tab!?! It's also a good way to check any item you want to download for any bad stuff (including add-ons from other developers), that may try to sneak onto your PC with said down loadable item!?!
DrWeb LinkChecker has been around for awhile & has proved itself 100 fold!?! They have made many changes to it over the years, like improved scanning speed (depending on your computers technical capabilities), keeping its database updated on a daily (hourly) basis, Improving their servers heavy demand for its use by the millions of users that constantly are scanning links etc. 24/7, plus much more!?!
**Unfortunately, like many other security products out there, it's not immune to developing the odd glitch like us users are experiencing with the recent updates to versions 2.5.8 & 2.5.9..... LinkChecker isn't working with my Firefox browser but does work very well with my Thunderbird email program (same update version & date)!?!
I have notified DrWeb developers via their LinkCheckers homepage online contact forms plus by email, as they don't seem to monitor this FF Add-ons page!?! I have found in the past that this is the best way of bringing a situation like this to their attention very quickly!?!
They will get it fixed & we all can continue to keep our PC safe by using DrWeb's LinkChecker, to warn us of those deceitful, unreliable, mischievous, scoundrels, rascals & scallywags who want to make our internet surfing miserable!?!
This is 1 very valuable security add-on that I highly recommend every one to acquire for your surfing pleasure..... It works well with most browsers & some email programs - just check it out at their home website!?!
