ErrorZilla Plus by Crend King

Rated 4 out of 5 stars 52 reviews

1,742 users

This extension is a replacement of Firefox official error page, which adds some useful tools to aid your troubleshooting.

The tools include:
- Google Cache (view the page cached by Google)
- Coralize (use Coral CDN proxy to connect again)
- Wayback ...
Collector's Note There are two addons that let you open a cached version of a webpage(i.e. a snapshot of a webpage, that now doesn't exist or would not open, taken in the past) - ErrorZilla Plus and Resurrect pages. Both use 5-6 services like Google cache, Wayback machine etc. to show you cached pages. Both do so by adding links to the error page that shows up when you fail to connect to a webpage. The advantage of "Resurrect pages" is that it opens the cached page for each of the 5-6 services in a separate tab, thus allowing you to try all services quickly. The advantage of "ErrorZilla Plus" is that it also adds a Proxy button for you to open the webpage using a proxy service in case the website is inaccessible at your location/your country.

Bookmark Current Tab Set by jkasprzak

Rated 4 out of 5 stars 22 reviews

3,226 users

Adds options to bookmark all tabs in a window (optionally without opening a dialog) and store them in a new bookmark folder that is given the current date (and optionally the time) as its name.
Collector's Note Bookmark Current Tab Set in one step( all tabs are bookmarked to a location you have already set in the settings) or two steps(a dialog pops up allowing you to chose a name and a location for the folder where the tabs will be bookmarked to). See also the addon "Bookmark all" which allows one step bookmarking described above. The advantage of "Bookmark all" is that it gives you a button that you can place anywhere you like and press to bookmark all addons - more convenient, but you cannot chose a custom name and location for the new folder thus created.

Rated 4 out of 5 stars 46 reviews

303 users

Store Notes on Websites in your Bookmarks.
Collector's Note Is a little buggy in the newer versions of Firefox. I have kept it in the list hoping that it will be improved by the developer in the future.

SelectionSK by Andrey Shemetov

Rated 5 out of 5 stars 65 reviews

1,400 users

Pops up user menu with useful tools (copy, highlight, translation, search, etc.) when text is selected with the mouse
Collector's Note Functions similar to the older and therefore more popular Auto Context addon. But AutoContext is no longer being developed by the developer and will not work with Firefox 3.7 and above(unless you use the workarounds I have written in my xomments on Auto-Context). Selection SK has all the functions of Auto-Context and then some more. So it is a sufficient replacement for Auto-Context. To me Selection SK is an indispensable addon. However, I keep it switched off using its red/green button until I need it, because unlike Auto-Context, Selection SK is a big addon and slows down Firefox.
