Close inactive tabs See how many tabs you have opened.

More than a few Active tabs mean active processes that take up your laptops RAM and drastically slow down its capabilities.

If they are important to remember, save them to bookmarks or stash them in a special Read Later list in a to-do application such as 2Do.

Clear Firefox cookies and cache All the websites you visit leave behind cached image files, which are supposed to speed up load times, and cookies, which can save you from having to log in over and over.

Those are big conveniences if they work the way theyre supposed to, but sometimes cache and cookies can cause glitches and slowdowns.

If Firefox is acting up, you can clear cookies and cache by doing the following: Click the Library button Choose History Clear Recent History Change the time range to Everything Click the arrow next to the word Details Select Cache and Cookies Then click the Clear Now button Alternatively, you can do this easier and safer with CleanMyMac.

Just click Privacy in the sidebar and then choose Firefox from the list.

Change the time range to Everything, and you can clear all of the cookies, browsing history, downloads history, tabs, saved passwords, and even autofill values.

Update Firefox and macOS If closing tabs and clearing the cache didnt work, its a good idea to update Firefox and macOS to its latest versions.

When Firefox is active, just click on Firefox in the menu and select About Firefox.

The latest available update should start downloading automatically.

When its ready, click Restart to Update Firefox and you are ready to go.
