Hi, I have seen some other people having the same problem and would like to provide some help with this issue. Based from a solution provided from a website which explains how to increase the performance of FF, please follow these steps to increase the performance of FF: Step 1: On your iPhone or iPad, tap the three-line menu and swipe down to choose Data Management. Step 2: Once you choose the option, you will see options such as Browsing History, Cookies, Cache, Offline Website Data, etc. Step 3: Switch on the button adjacent to Cache and Offline Website Data (or others, if needed). Tap Clear Private Data > OK. Link to website: https://www.news18.com/news/tech/is-mozilla-firefox-slow-on-your-pc-or-phone-heres-how-to-rediscover-the-performance-4036169.html
