How do I clear all my thumbnails without doing it one at a time?
When I open Firefox, I see a thumbnail on the screen for everything I did in my last session. Obviously this can add up and isn't particularly useful to me. How can I clear these rather than the one at a time click on the X method?

This homepage will learn your most used sites eventually, however, the thumbnails are customisable, you can edit where they link to and pin/unpin there position on the page. or you can go to edit>preferences and change your homepage to something else. clearing your cache and history should also do the trick
Note that Firefox still creates thumbnails of visited pages in the thumbnails folder when you disable the about:newtab page.
You can create these Boolean prefs on the about:config page to prevent Firefox from generating thumbnails for the about:newtab page.
- name: browser.pagethumbnails.capturing_disabled with value: true
- name: pageThumbs.enabled with value: false
You can open the about:config page via the location bar and accept the warning.
Delete the thumbnails folder in the Firefox profile folder to remove already stored web page thumbnails.
You can use this button to go to the Firefox profile folder:
