Please explain what you mean by "control".
That website is used for searches, instead of using Google?
If so, which of the three sections of Firefox is that search engine being used?
Or all three sections?
I deleted the home icon from the navigation bar and changed my default search engine from arccosine. It seems arccosine is part of the search engines that are there as choices in the default searchbar. Why arccosine was chosen is anyone's guess but Firefox should have informed the users about this.
Please explain how you changed the default search engine. I cannot find any way of doing it despite spending too much time in the help section.
Is the ARCCOSINE software safe to use for searches?
I cant vouch for the validity of Arccosine.com but from what I can tell it is just some random website that tries to imitate google.com's homepage. It hijacked my entire browser including the Homepage, search engine, and keyword.URL entry. I dont know to what extent this damage is, but I got rid of most of it by immediately going into my firefox sync settings and replacing all current data with server data.
I got this by searching for a way to download books from Google Books. Likely culprits are Google Book Downloader or GooReader. I think Gooreader is the most likely suspect because after installation there was no option anywhere to uninstall it. By chance I attempted reinstalling it and that allowed me to uninstall. Furthermore, the GooReader software claims to be free but every feature is locked down unless you buy it.
i guess the problem kenb posted here is about the change of default search engine, i changed back to google, and here is how it could be done
1. open a new address bar and type in about:config
2. type in keyword.URL
3. change the search engine url to http://www.google.com/search?ie=UTF-8&oe=UTF-8&sou
The culprit is Google Books Downloader. I just installed it and started having the arccosine problem immediately after that. I then scanned my pc with Antimalware but nothing came up, so it looks like i have to change my browsersettings back manually. Also Chrome seems to be unaffected, just Firefox an IE.
