Firefox ios slows down during use
Initial performance is good, but over time especially when tabs are opened and closed frequently responsiveness to user input (e.g. tab switching, opening/closing tabs, response to hyperlinks) becomes very slow. After force quitting and restarting, performance is good again for some time. I exclusively use private tabs.

Hi Peter,
Firefox for iOS 143.2 will be rolled out in the near future. You may want to keep an eye on it and update immediately to see if it improve the performance on your device.
Sorry about the inconvenience!

Thanks. Will check after release
I have installed v144, and unfortunately it is still not improved, with continued use, Firefox’s responsiveness becomes worse.
You’re not alone — Firefox on iOS can sometimes slow down after being open for a while. Here are a few things that usually help:
Clear cache and website data: Go to Settings → Firefox → Data Management → Clear Website Data. This can free up memory and speed things up.
Close background tabs: Having too many tabs open can cause lag, especially on older devices.
Update Firefox and iOS: Make sure both are on the latest versions — newer updates often fix performance bugs.
Restart the app or phone occasionally: iOS can slow down apps that have been running for a long time.
