Simple and does the job.

Don't Install- -This will break your Internet Rated 1 out of 5 stars

As soon as I installed this my Internet stopped working. All my other home network devices can access the internet fine, but the computer I installed this on, will only connect briefly after a reboot, and then after a minute or two, no sites can be reached.
Plus the 'support link' given for this plug-in is bogus, go ahead and try it and you will see its just some place holder auto generated site with no support.

Better info would be very helpful Rated 4 out of 5 stars

The developer should have mentioned the only button that works correctly is the one in the "Arrange" area as mentioned (actually the customize toolbar button repository), unlike the button you find on the addon bar.

If you do not discover this on your own, the extension becomes far less useful and a mystery to operate.

The button resembling a single "gear" cannot enable or disable the extension, and does not indicate whether the extension is enabled or disabled.

The second button, resembling 2 gears, turns the extension on or off with a left click, and lets you know with a mouseover whether the extension is enabled or disabled.

Also, can anyone tell me how to permanently remove the addon button?

good idea, with usability issues Rated 3 out of 5 stars

Few usability/user friendliness issues:

- It does not remember state sometimes
- you can't clearly tell if the dns caching is on or off
- mouse highlights icon, but left-click does nothing (it's not clear if it should - most icons do, so it'd be expected IMO)

And as suggested, it'd be good ot have a more distinctive icon for it. That gear is more of a 'settings' icon than a dns cache.

FF19 on Windows, Worked Rated 5 out of 5 stars

Installed, activated, dragged to navigation bar, right clicked on its icon, and then clicked "Flush DNS Cache." Immediately, the site I expected to be able to view, appeared. With but little time using this Add-on, I feel it has added onto my life expectancy by reducing stress.

It clears ALL the caches Rated 1 out of 5 stars

WARNING!
I checked the source code and did a test to double-check my suspicion but "Flush DNS Cache" option does not only clear the DNS cache. It also clears all the content cache (saved in disk and in memory).

There are other better extensions that clear only the DNS cache so consider using them to avoid this side effect.

Lifesaver. Works fine up through at least Firefox 10.0a2 with extensions.checkCompatibility.10.0a set false. Just wish Firefox would stop failing DNS lookups in the first place...

works with 6.0 Rated 5 out of 5 stars

It works with Firefox 6.0. You just need to edit install.rdf and change maxVersion attribute

Nice but the button is the generic gear icon and should have a custom one to make it stand out. Would have gotten 5 stars if that icon was different.

Works as expected. Thanks for this extension!

Seems to randomly disengage from ''disabled'' to ''enabled.'' Why does it not stick where it is told?

First: STOPPED me from accessing some sites, FF hanged without any response.

I noticed that (after troubling my host provider) on 3.5.5 version.

Other: from start it's like this - sometimes works, sometimes not.

Since this is primary developer addon, i think it should be more reliable.

The Flush DNS cache function works but the Enable/Disable does not seem to work. I have to manually flush each time I change my hosts file. Beats restarting FF each time but would prefer not having to manually flush. FF 3.5.3.

Some Bugs Rated 1 out of 5 stars

I tried using this extension (FF 3.0.6 & FF 2.0.0.20), and even verified in about:config that it was changing the values this addon claims to change, but I can not get it to refresh the DNS any faster than without the addon at all. I found this addon ( https://addons.mozilla.org/en-US/firefox/addon/7408 ) to work right away.

Unfortunatly it just didn't work. The icon appeared in the status bar, however left and right clicking on it did nothing.
