The browser is now the client of choice in most applications on the web. It is hence important to familiarise oneself with its inner workings to the extent of safe and consistent usability whist being able to detect malfunction and malicious intrusion.
Finding your browser profile
- Leading browsers use either the Microsoft engine or the Mozilla engine. Firefox, Chrome, Netscape, and the like use the latter.
- Important settings that the browser will use reside in the files in the profile folder.
- Click the menu button , click help and select Troubleshooting Information. The Troubleshooting Information tab will open.
- Under the Application Basics section, click on Show Folder. A window with your profile files will open.
Alternatively, in Windows, Click the Windows Start button, and select Run…. Type in: %APPDATA%\Mozilla\Firefox\Profiles\ then click OK. A window will open containing profile folders.
Plugins and Extensions
Support for NPAPI plugins in Firefox except for Adobe Flash will end in March 2017, when Firefox version 52 is released. Some of the plugins that will no longer load include Java, Microsoft Silverlight and Adobe Acrobat. See this compatibility document for details.
Over the past few years, Firefox has implemented various Web APIs so that websites can do the same things they’ve always done without plugins, so you will most likely not notice any change to your browsing experience using native replacements for these plugins.
Safe browsing settings
Avoid memory bloat and other telltale signs like extreme slowdown and tweak the browser settings.
- Check browser memory usage with the about:addons-memory 2016 firefox extension.
- Default Search Engine and Homepage settings are common signs of the browser being hijacked.
- Keeping the Homepage setting blank (about:blank) and empty new tab settings are advised.
