Hello, My macbook was very slow and Firefox kept it crashing, so I thought I would tidy up my FF windows and tabs. I used the tip I copied below, but nothing happens when I click the bookmark folder which contains all my tabs (in fact I have several such folders). I have looked around for a solution, in vain. Can someone help? The easier the better as I am not a techie. My macbook's MACOS is Catalina (up to date for my macbook pro 9.2, mid 2012), and I'm using FF v. 95.0.2. Many thanks.

Copy of Mozilla help tip: To bookmark all open tabs at once: Right-click on any of the tabs, choose Select All Tabs from the context menu, then right-click on any tab and select Bookmark Tabs…. Give the new bookmarks folder a name and choose which folder to store it in. Click Add Bookmarks to finish.
