My Firefox browser was updated to the most recent version (153.0). And since then, it will always freeze up within a few minutes of me opening it, even in troubleshooting mode. Even if I keep clicking, it’s still stuck and I’m forced to close it.

I did turn off hardware acceleration before, and it still doesn’t work.

When my system slows down and takes forever to download, I go to task manager and find 15-20 entries for Firefox when I have only 1 or 2 pages open. Why are they continuing to pile up and slow down my machine and how do I stop it from happening?

Hello everyone,

I've recently noticed that Firefox has become slower than usual. Some websites take a long time to load, and occasionally the browser feels unresponsive even though my internet connection seems to be working fine. I've already tried restarting Firefox and clearing the cache, but the issue still occurs.

Has anyone experienced something similar or found a solution that improved Firefox's performance? Any suggestions would be appreciated.

Thank you!

When I launch Firefox, it uses well under 1GB in memory, but then it starts to increase that amount quickly in just a few minutes and gets up to 50+GB, causing error messages to pop up repeatedly until it uses all resources and locks up my computer. I have updated my MAC OS and the Firefox app, uninstalled the Firefox App and still have the same problem.

Please help

On a new laptop with Win11 Home (x86-64) with Firefox just installed, the cache size is 54 MB. When Privacy and Security -> Clear Browsing Data is clicked, Firefox hangs - no input is accepted and nothing appears to be happening. On closing Firefox and then reopening the cache size is reduced and Clear Browsing Data operates as expected.

Why is the cache size (54 MB) so large? Why does Clear Browsing Data hang Firefox?

Dear Support,

Firefox exhibits significant performance and usability issues related to its cookie and data storage management. Despite implementing ad blocker extensions, the browser remains saturated with cookies and persistent advertisements. Regularly clearing browsing data and cookies is necessary; however, navigating to the settings menu is time-consuming. I recommend developing a browser widget that facilitates rapid data clearing directly from the toolbar or frame. Additionally, implementing a session-saving feature to preserve a set of pinned tabs upon closing and reopening the browser would enhance workflow efficiency, allowing for a quick start with a predefined workspace.

This is all happening while using it for simple tasks like search or copying a text.

Furthermore, the browser experiences severe performance degradation when utilizing certain web applications, such as Kapwing for video editing. Since uninstalling Vivaldi, I am considering migrating to an alternative browser due to these issues. Tasks that typically require one minute are now prolonged to hours, as the browser intermittently becomes unresponsive, effectively limiting usability. This sluggishness persists even after system restarts, with CPU utilization reaching approximately 50%, as detailed in the attached performance report. Notably, I encountered a significant delay—up to an hour—to correct a single spelling error or open a new tab, indicative of underlying performance bottlenecks.

Please address these issues to improve browser stability and usability.

Estimator Just tell me how long this is probably gonna take: 4 to 16 hours. Not kidding!
