Since the latest version of this add-on it is totally unuseable in Firefox 149.0.2. Am close to uninstall this addon once and for all. It has become worse and slow with every new update. Activating this add-on and watching IG stories, reels or pictures fills within minutes the whole memory (RAM) of my PC. 32GB installed and a useage of 99% totally slowing down the whole machine. Deactivating this addon and using the one that names also "Instagram Downloader" - everything is fine and works perfectly.
