This helps when Firefox is slow

Deleting add-ons, extensions and themes
Firefox can be easily adapted to your own needs with themes and add-ons. But sometimes it just gets too much for the browser. Check your extensions and remove anything unnecessary. Because too many "frills" can make Firefox very slow. You can find more information about add-ons in Firefox here.

Empty the cache and delete cookies
When using the Internet, Firefox repeatedly saves small amounts of data, the so-called cookies. With their help you will recognize a website. Here you can find instructions on how to delete cookies. Firefox also creates a history of pages visited, saved passwords and the like, the cache. In this post, we are going to show you how to clear your Firefox cache. Deleting cookies and cache ensures more free storage space. Because every single cookie has to be loaded itself when loading a website. The more data is now saved, the more data has to be reloaded again and again from Firefox.
Changing the start page
If Firefox is very slow to start, the problem may be with your start page. Firefox loads the homepage first. If it is very extensive or if you have set several tabs as the start page, there may be problems. In such a case, you should set a different start page. More information on changing the homepage in Firefox can be found here..
Block unnecessary content
Some websites are actually very simple and should load quickly. But due to extensive advertising, this website is slow again. In such cases, the problem is not with Firefox. Here we show you how you can block advertising on Google, for example.
Topping up slow internet lines
The problem may not be Firefox or your computer at all. Internet lines with a speed of 16 Mbit / s are a minimum for most apps these days. Slower bandwidth can cripple some apps. Do you want to know how fast your internet is? You can find a speed test here.
Avoid heavy
hardware usage Your computer hardware may be out of date. Obsolete hardware can slow down your computer. This will of course also make your browser slower. A computer today should have at least 4 GB of RAM. Less RAM ensures slow computing processes. Find out how much RAM is in your computer here.
Check background
software If programs other than Firefox are open, these can slow down your computer. Programs that access the Internet in particular can cause problems. The anti-virus program may be performing a standard scan that requires a lot of memory. Or Windows downloads an update in the background. Close all unnecessary programs. Here are tips on how to turn off Windows Automatic Updates.
Viruses or similar malware can also paralyze your browser or computer. Here we explain what malware is.
