This is a very simple replacement for Simple URL flipper
https://addons.mozilla.org/fr/firefox/addon/advanced-sequenced-url-flipper/ for previous page.
Useful if you want to browse forums, threads, images, pages with a version number or anything with a number.
If you have a page like this
http://www.site.com/page/3, hitting the button will go to
http://www.site.com/page/2.
Works also with
http://www.site.com/page/cam002.jpg or
https://www.foundation.org/en-US/browsername/56.0.1/releasenotes/.
Dead url (holes in numbering) are bypassed. If only
http://www.site.com/page/cam002.jpg and
http://www.site.com/page/cam005.jpg exist, trying to go previous page from
http://www.site.com/page/cam005.jpg will go to
http://www.site.com/page/cam002.jpg. Skipping dead url will go no more page than the "hole limit".
This is a one button version of this addon :
https://addons.mozilla.org/en-US/firefox/addon/nextprev-page/.
Required permissions :
- activeTab : to change current url
- storage : to store the options
- <all_urls> : to test url for bypassing dead ones.
