March 19, 2025 by our News Team

Mozilla has released a new update for Firefox 136, fixing bugs related to clearing browsing history, password manager prompts, and high CPU usage after system suspension.

  • Fixes an issue with clearing browsing history
  • Resolves a bug with the Firefox Password Manager
  • Fixes a CPU usage error


Mozilla has just released another update for Firefox 136, and this time it brings some important fixes. The new version, 136.0.2, is now available and should start rolling out to all users soon.

One of the key bug fixes in this update addresses an issue where selecting the option to clear browsing history upon closing the browser would also erase cookie and web application data. This meant that users had to constantly log in again to different websites. Talk about a hassle!

Another bug that has been resolved is the annoying prompt to save data in the Firefox Password Manager that would pop up at unexpected times, even when there were no active fields. I don’t know about you, but I find those unexpected prompts quite frustrating.

And here’s some good news for those who have experienced their CPU usage skyrocketing after their system goes into suspension. Firefox 136.0.2 fixes an error that caused the Firefox process to hog CPU resources in such situations. Phew, no more unnecessary strain on your computer!

This update comes hot on the heels of last week’s release of version 136.0.1, which also addressed some cookie and keyboard shortcut issues. It’s great to see Mozilla actively working on improving the browsing experience for its users.

If you already have Firefox installed, keep an eye out for the update notification. It should be arriving on your device in the next few hours. So sit back, relax, and let Firefox take care of those pesky bugs for you. Happy browsing!
