Favorite WebExtensions?


Information overload – thirty pages. Related to that type of search result, from a few months ago, with added emphasis:

That’s much smarter :+1: however, at least two listings seem irrelevant to organisation.


Alpha testing, in Mozilla’s beta channel, began 2017-10-12.

I see developer attention to WebExtensions-related issues. Thorough feedback, now, from end users might allow the developers to cease classifying Greasemonkey for Firefox 57 as experimental before the release date.

For what it’s worth: no problem with the one script that I use (for MacRumors Spy).

Really. HTTPS Everywhere is already WebExtensions in its Development Versions.

Thanks @nova6k0, https://addons.mozilla.org/addon/https-everywhere/reviews/939609/ refers to https://www.eff.org/files/https-everywhere-test/index.html – is that the proper unstable channel?

It seems they just released a WebExtension version yesterday on the main channel: https://addons.mozilla.org/en-US/firefox/addon/https-everywhere/versions/?page=1#version-2017.10.30



Similar to legacy ScrollyFox. AutoScrolling is:

  • easier to stop
  • not as broadly applicable.

Extensions for paging and scrolling with Firefox 56

Stylish to Stylish (not to Stylus)



From https://addons.mozilla.org/addon/stylish/versions/?page=1#version-2.1.1 (2017-10-31):

Last legacy version, getting ready …

@amyt thanks again.

@sdevaney and colleagues: please be prepared to remove Stylish and Stylus from the finder, when Stylish becomes ready (not experimental). Thanks.

I’m suggesting a better replacement for ReloadEvery (https://addons.mozilla.org/en-US/firefox/addon/reloadevery/)

For FF57, migrate to ReloadMatic (https://addons.mozilla.org/en-US/firefox/addon/reloadmatic/).

It seems ReloadEvery already has a recommendation on ExtensionFinder (Tab Auto Refresh), but the latter does not really have anything in common with the original addon as far as the UI goes. ReloadMatic is a much better match as it is very similar to ReloadEvery while at the same time offers additional features.

Have you tried Scrollkey?


Nice recommendation! I’ve adjusted the tools.

Thanks, Scrollkey is not a replacement … in retrospect, it’s probably unfair to use this topic for things that might be irreplaceable. Sorry. I removed three of the five extensions from post 101 above.

Instead please see the list at post 35 under Concern about WebExtensions exclusive strategy from add-on authors and users;

I accept that some of these will be irreplaceable. For posterity …

Thanks for including Search by Image! Here are some more legacy add-ons which could be mapped to it:

Keyboard shortcuts: direction from Mozilla to use a legacy extension

Keyboard shortcuts - Perform common Firefox tasks quickly | Firefox Help (undated) begins with emphasis, before listing the shortcuts:

Note: Keyboard shortcuts can be customized using the Menu Wizard extension.

Menu Wizard is legacy (requires a restart of Firefox) and not found by Extension Finder. More broadly , nothing is found for key – partially blocked by these WebExtensions Mozilla bugs, I guess:


Mozilla bug 1415071 - Keyboard shortcuts: direction from Mozilla to use a legacy extension


Print/Print Preview Context is a replacement for Print/Print Preview.

Full disclosure, I am the developer of Print/Print Preview Context, since the original add-on was abandoned for 2+ years.

LeechBlock NG (a rewrite of LeechBlock that uses WebExtensions) is now available on AMO. This should be the official replacement. :slightly_smiling_face:

Re: the collection at post 38 please also consider Mozilla-featured extension Print Edit WE as a replacement for Print/Print Preview. Thanks.

Hi, one more, Tab Auto Reload also maps nicely to ReloadMatic (which I’m the developer of). Thanks!

For Sort Tabs, Extension Finder makes a non- specific recommendation:

Another specific recommendation:

Sort opened tabs and find duplicated

Five gold stars from me https://addons.mozilla.org/addon/sort-opened-tabs/reviews/950983/ and it’s probably one of my top ten extensions for Firefox Quantum.


All Tabs Helper is useful, but it occupies the sidebar. So for example, you’ll be unable to use All Tabs Helper alongside Tab Center Redux.

I prefer Sort opened tabs and find duplicated because (as shown in the screen recording) it can be used without obscuring any of the sidebars. Also because it presents a red alert, in the toolbar of Firefox, wherever there’s exact duplication in a window.

Even though there is a snaplinks plus version available, it is a bit buggy (and alrady a year old) without any new version in sight. If there is any decent alternative that lets me select as well normal links as well as images linking to somwhere, please let me know

I asked the FoxyLink developer to extend his as well to allow a user to copy both the text for the url and the url to the clipboard for multiple links at the same time. Also to allow the user to choice of opening the links in new tabs.

I use multi links plus currently and have been using it for years for various things. Mostly for work.
