Lately when opening multiple tabs in a folder on E-Bay, often this error msg occurs on the later opening tabs (folder of 60 tabs) E-Bay says try Chrome browser, but that browser does not import the folders needed. Years ago doing this solved slowness problems: Control panel/Internet Options/General/Browsing History/Settings/set disk space to use to 1024. The browsing history would be deleted before the computer would be turned off. E-Bay says try Chrome browser, but that browser does not import the specific folders needed. Edge used to not allow folders with tabs. I have divided the folder of 132 tabs, where this problem started, into two folders of 72 and 60 tabs, still happens about every fifth time the folder would be opened. Any fix from Mozilla?
