Very nice, I was looking for something like this for a long time! It is working exactly as advertised.

There is no way to block a domain. For example: http://*

Re: There is no way

You have misunderstood the instructions. In order to block "http://*", you need to block "" and nothing else. All pages and subdomains for that domain will be blocked.

super Rated 5 out of 5 stars

worx as advertised.
here's a little trick for all those who want to modify the context-menu-entry from "block this!" to e.g. "block from History" or whatever you like. i modified this 'cause i found it a bit confusing so i changed it into "block from History":
-download HistoryBlock manually by right-clicking the "add to FF"-link and choose "save link as" to a folder of your choice.
-rename "addon-8631-latest.xpi" to ""
-extract the zip-file.
-open the file "History Block\locale\en-US\overlay.dtd" with a Text-Editor.
-replace ONLY THE WORDS "Block This!" and NOTHING ELSE!!! with text of your choice.
-save the file.
-add the FOLDER "locale" to the "" by right-clicking the folder "locale" and choose "add to..." "".
-rename "" to "addon-8631-latest.xpi".
-open FF-AddOns-Manager and choose "install AddOn from file...".
-install the AddOn and restart FF.

subdomain exceptions Rated 4 out of 5 stars

really helpful for blocking sites I visit multiple times daily so it clears up my history storage
would be great if there could be a list of blacklisted sites available as I sometimes forget which ones I've added to the list and may want to whitelist...
also, for some sites I don't want to block the whole domain and only specific subdomains (ex. social dashboards/walls/etc. rather than individual pages)

Does not block Flash cookies Rated 3 out of 5 stars

Not bad, but doesn't handle Flash cookies, when Firefox's built-in 'Private Browsing' does. And Flash cookies talk, man do they talk :)

I need Block This button in the window of Ctrl+Shift+B in Firefox. I should be able to blacklist a bunch of websites in my history.

need a less aggressive mode Rated 3 out of 5 stars

would be fantastic if a less aggressive mode would be introduced. you could alternate between the secure/lock down mode, and the insecure mode.

the less aggressive mode would basically permit listing and editing the blocked sites, and cause no issues for cookers/passwords, etc.
this is useful for a development environment where you need to open the same sites over and over, but don't need or want them to be logged, because it's just trash. it fills up your browsing history and mangles with the useful history you actually want to keep. private browsing does not resolves this because of cookies/passwords, and doesn't works like incognito in google chrome.

would also be great to allow users to customize exactly what would be blocked: browsing history, download history, form, etc.

Excellent addon. The performance problems it once had are gone and it's absolutely great :)

2 minor complaints though:
- No Firefox 5 support so far
- Unable to have stored passwords for blocked sites, would be nice if this "password blocking" would be optional. I just want to have no history, I don't have a problem with a stored password...

Re: Excellent addon

I have added and added Firefox5 support. Soon, a will be released (pending review) which makes the code much cleaner and keeps other addons from breaking HB (and vise-versa).

Passwords... this comes up a lot. The problem with passwords is that I simply do not know enough about the interface or what Mozilla makes available through it to actually try and store them (or ignore deleting them). On the one hand, if you removed all traces of having visited, but someone went onto your computer and went to and saw that the un/pw fields in the login were already filled in... it would seem that the game was lost. On the other hand, if the only thing HB is being used for is keeping those entries out of the history/closed tabs listings, then you might LIKE the fact that your UN/PW are stored for and show up when you try to log in.

I will look into the passwords api to see what I can find, but no promises on this one until I have more specifics.

Earlier you replied to someone saying:
"No option for viewing what i have blocked so far"

I understand if you're trying to 'hide' sites that you've visited then this is would be a great feature. But, some people could be using this add-on for other reasons. For example, I'm using it to block sites that I don't want cluttering up my history. Usually gaming sites that I don't care to remember what pages I visited and don't need a couple hundred pages stored in my history, slowing things down.
Is there anyway to add this as an option? Maybe turn it off as default, and if it's on, password protect it or something?

This review is for a previous version of the add-on ( 

Password protection is a suggestion which comes up often instead of 1-way hashing. To put it simply, I do not know what (if anything) I have available in the api to actually get after strong password protection. Additionally, I do not fancy writing my own password protection implementation for HB because it would be hard, I would probably get it wrong, and it would do something that I fundamentally do not care for.

Here is an example, when you hash, it becomes 97612fdad3f6b17f61d6912994b66ea7b7bacc99. For one, that is completely non-human-readable, so we really don't care whether anyone can access that. For two, sha1 has been proven to have collisions, which simply means that even though someone can try infinite inputs to try and get 97612fdad3f6b17f61d6912994b66ea7b7bacc99 as an output, they might find that "asfbniqnqeaviubqqpivvioboqq" also maps to the output 97612fdad3f6b17f61d6912994b66ea7b7bacc99. Just finding an input doesn't win the battle... finding the RIGHT input does. ADDITIONALLY, that may only map to if the haxor attempted to find THAT entry. My personal blacklist has HUNDREDS of these hashes, many of them are "", "", "", etc in testing HistoryBlock development... picking the right hash, then generating the rainbow tables then using them may EVENTUALLY find but even then they only have one of my hashes de-hashed.

Conversely, if the blacklist is password protected and the password is compromised (via a vulnerability in the protection implementation or just brute-forcing the password), then ALL the domains are listed. This is potentially scary.

I WILL look into this to see if I can get an implementation that makes sense (and is off by default), but I will make it TOTALLY understood by any user that it is dangerous (in my opinion) to use the password protection model as opposed to the hash model.

Can you make the a replica of the Stealther? It seems the author of Stealther has disappeared and he isn't updating it to work with FF4. So, like instead of blacklisting anything, just pressing a button on the bar to disable history, cookies, closed tab list, etc. That would be super.

Re: Stealther

An undertaking like taking it upon myself to update Stealther (a huge addon, btw) is probably more than I am willing to do at present. Have you tried the FF incognito mode? Private Browsing, I believe is what it's called. My gripe with that is that it opens an entirely new window rather than a single tab.

problem Rated 5 out of 5 stars

The Historyblock add-on is an awsome idea! Thank you for it.

yet it doesnt works for me, can someone please help?

the Historyblock works only as a onetime block
When I block a site it removes it from the history but when I then restart Firefox and go to the site it seems not to maintain the block, the new entryto the site appears in the history.
why is that happening?

i have tried to block it both through the addon menu and by rightclicking when on the site, both do not maintain the block after restarting.

Warning: Deletes your passwords Rated 1 out of 5 stars

For every history blocked site your passwords are deleted too - without any warning!

This review is for a previous version of the add-on (1.3.5). 

Re: Deletes your passwords

This was a limitation of the API in the 1.3.5 build. Basically, I had to use a call to the Private Browsing mode functionality to delete ALL the information related to a blacklisted site; I THOUGHT I had a method in place that would (when a blacklist-close occurred) capture cookies, passwords, etc and set them back after the history clear (this was to get rid of the recently closed tab entry... which FF broke from the previous build to 3.5). Long-story-short, I believe that this is no longer a problem in the 1.4x build, I would love for you to retest and post results.

Useful addon!! This is great!, which both hoped to prevent unwanted certain domains appear in the awesome bar!. Please keep well and see if you can add new options like wildcards and others. I look forward to the update for FF4.x releases. Thanks!

Handy add-on, but is there a way to retain the saved passwords for some sites? Some sites that require log-in, I find that every time I open up a link in a new tab it keeps asking me to log-in again.

I agree with Takashi SASAKI.
I would like to have controls over what kind of entries to blocked.
At this moment, switching the value of extensions.historyblock.blockcookies does not seem to change anything.

This review is for a previous version of the add-on (1.3.5). 

Re: blockcookies no effect

This is mainly due to a rewrite in the FF3.5 code that took me a LONG time to figure out (and a bug I had to report about their max-ints... but w/e). Long-story-short, if I can EVER find some spare time, I will get this fixed asap.

As for WHAT to block... it doesn't really work that way. Currently, your only option at the code-level is to remove things. You can either remove EVERYTHING, or go back to older builds of HB (which probably don't work anymore, but their implementation ideas, mainly) and remove history entries, cookies (or not), and try to "break" the recently closed tab entry. Unfortunately, HB is forced to delete everything for that domain, and try and bypass that stage by "remembering" the cookies (or not) and re-instituting them after the full-whipe.

This is a handy implementation if you frequent forums (or what have you) and you want your user to stay logged in but not show up in your recently closed tabs menu or history entries. However, there are some instances where NOT remembering cookies would be ideal.

Ultimately, what I think I'd like to do is redo the options menu to allow you to specify at each blocked entry whether you would like those cookies to be remembered. Something like "block the wow forums, but remember their cookies; block but don't remember their cookies," would be a potentially useful way of doing this.

This addon useful for other options too.

If the user set changing it to "history" only in tools>options>privacy>location bar option and add the visited site to HistoryBlock, can block address from the awesomebar.

No more bookmarks and history there just the typed URLs. Cheers!!!

But need some options for HistoryBlock, like import/export sites, because type address for every install not too good, and need export from bookmarks, because hiding from saved bookmarks from addressbar. Export from file without type every URL could be better.
