To do so press Ctrl-Shift-H to open the History window, right-click a history entry and select Forget About This Site. If you notice slow downs on a particular site, you can remove information that Firefox has stored about that site only.

The easiest way to clear the history is to press Ctrl-Shift-Del and delete the cache as well as the browsing data and download history. Data that is saved by Firefox is also increasing the size of the databases the browser has to load. You may want to clear the browsing data regularly because of that. While this speeds up future web browsing, it sometimes may result in errors, for instance when a cached page is loaded that is either out of date or corrupt. It unloads tabs after a certain amount of inactivity to free up resources.įirefox saves previously visited web pages to the cache from where they are loaded. If you happen to open lots of tabs during a browsing session consider installing the Unload Tab add-on for Firefox. This loads the tabs when you click on them and not on the start of the browser. Click on Firefox > Options, switch to Tabs there and make sure "Don't load tabs until selected" is enabled. If Firefox is slow when it is loading you may want to consider the following configuration changes. If it does, try and find alternatives for the scripts either in form of other userscripts or extensions.
Try disabling them to see if it resolves your issue. If you have installed Greasemonkey or Scriptish in the browser and make use of userscripts, they may also be the culprit depending on what they do.

Pro Tip: Hold down the Shift-key while starting Firefox to display the Safe Mode window. If you are still running an older version of Firefox, try upgrading to the latest version by downloading it from Mozilla or using the internal updater. Mozilla spend engineering time on optimizations and they began to show recently resulting in a leaner, slimmer and faster browser. This may sound like the most obvious thing and it is. If you are running Firefox currently and notice it slowing down considerable over time or right away, I suggest you try the following fixes to resolve the issue. This was not always the case, especially during the Firefox 4 days when the browser started to eat memory like crazy. While I do my best o ensure that, for instance by running it without plugins and with NoScript, it is the complete package that makes the difference. It is as stable as it gets, does not use too much memory or cpu, and is a pleasure to work with.
I have to admit that while I do not agree with every decision Mozilla makes in regards to Firefox, I can't really complain about the web browser's performance on my system.
