While using Firefox, you may have experienced issues with the speed at one time or another. A quick comparison with other browsers will show you that only Firefox seems to be suffering from slow speeds, while the rest can load pages quickly. These are caused mainly due to configuration issues and the use of extensions. Installing memory-consuming apps onto the browser is known to affect its loading speeds. Below are some quick fixes to resolve slow speeds in Firefox.
Firefox can run slow in computers having plenty of RAM and processing power. There are various options in Firefox for improving the performance of the browser by allocating its usage of the available resources. You can alter these settings of the browser to give it the best performance depending on your system hardware. For this, go to about:preferences > General > Performance and uncheck the box near the Use recommended performance settings.
Tick the box labeled Use hardware acceleration when available, which actually uses the graphics card of your computer rather than the processor for a smoother visual performance. You can also change the Content Process limit by selecting any number from the drop-down menu. If your system has at least 8 GB of RAM, it is better to switch to more than four for the best performance.
One of the major issues with Firefox is that it can take a lot of time to start compared to other browsers. This issue can occur after using Firefox for a while, and can often be frustrating, especially if you are trying to use the browser for anything important. An effective way to fix this issue is by going to about: preferences > General and unchecking the box near Always check if Firefox is your default browser. Then, go to General > When Firefox Starts and select the Show a blank page option.
Firefox can use more RAM when used for extended periods, due to the buildup of cached and other data. The use of various add-ons or plugins can also slow down the browser and affect its speeds. To fix this issue, restart Firefox in safe mode and then go to Options > Help, and then select the Restart with Add-ons Disabled option. Click on the Start in Safe Mode option and see if the browser is running faster. Try disabling the add-ons and plugins to check the speed of the browser.
