The safe mode in Mozilla Firefox is a really useful way to troubleshoot issues related to stability and performance. Safe Mode is a special mode where important browser settings are temporarily reverted back to their defaults and all add-ons are disabled. It is easy to figure out what might be causing problems by comparing Firefox behavior in normal mode to its behavior in Safe Mode.
While Mozilla Firefox has good support for HTML5 standards, you might have noticed that it does not support all features required to play videos on YouTube without having Adobe Flash Player installed. It supports the required HTMLVideoElement, but some videos do not play anyway. Those videos require the Media Source Extensions feature which is disabled by default in Firefox. By default, this option is off in Firefox, so the browser is not able to play some HTML5 video streams. If you prefer HTML5 videos over the Adobe Flash Player, you might want to enable Media Source Extensions to get advanced support of HTML5 videos in Firefox.
If Mozilla Firefox crashes for you or is giving you slowdown issues like consuming excessive amounts of CPU, then you can try the Reset function of Firefox. It's a useful but rarely covered feature. Resetting quickly solves any issues caused by damaged or incorrectly configured settings, and saves your time. It can resolve issues related to unexpected Firefox behavior, e.g. recently I removed a malicious user script running in my friend's Firefox profile using Reset. Let's see how to use the Reset Firefox feature.
In any browser, the Find bar which appears by pressing Ctrl+F is very useful to quickly locate any word or phase on the page without manually searching for it. Mozilla Firefox's Find Bar has been severely lacking in some key functions, especially in more recent versions of Firefox. Let's look at two extensions which add essential functionality to the Find Bar.
Besides the new Australis UI coming soon to Firefox, Mozilla now plans to show ads on the new tab page of Firefox as a revenue source required to support the browser. These changes are very frustrating for those users who are used to having a customizable and ad-free web browser. Although Mozilla will most likely make those ads unobtrusive, many Firefox users may want to stop using the vanilla Mozilla Firefox build. Let's see where you can migrate and try to analyze what the alternatives are to Firefox.
We always say that the best feature of Firefox is the unrivaled customization the browser offers. Even if you don't like the UI and default look of Firefox, addons, themes and personas can change it. Accessing extension options in Firefox is cumbersome today. Firefox opens a separate addons page in a new tab to manage them. It takes several clicks to access extension options and then you have to close the Add-ons page every time. This is where an extension called 'Extension Options Menu' helps.
Firefox 27 was recently released and many users faced multiple crashes in the browser. It's annoying to not know what is crashing Firefox, so I decided to write this short post to help you to troubleshot the issue and fix it easily.
As you might be knowing, starting from version 29, Mozilla plans to ship Firefox with a new Australis UI, which is already available in the Nightly Builds of Firefox. Recently we covered how to disable Australis and restore the classic theme in Firefox. In the latest builds, Mozilla has added a native option to enable the titlebar for the Firefox window. When the titlebar is enabled, it shows the current page title and browser icon. To enable it, follow these simple steps.
Firefox is truly a very customizable browser. It has lots of hidden features and options which are not accessible via the browser's preferences UI. Add-ons enable many of these features to be customized in a user friendly way. Others can be tweaked with the built-in configuration editor (about:config). One such secret feature of Firefox is the ability to change the icon of the main window and bookmarks as well as library windows. You can even set your own icon for the downloads library, the bookmarks window, and the view source tool without using any third party tools. Let's see how it can be done.
