Concern about WebExtensions exclusive strategy from add-on authors and users

Diigo

Great, thanks.

Session Manager

Showcase

Thanks. I’m already working without it (incompatible with Firefox 55).

As a limited substitute there’s the Switch to tab feature of Firefox when using FAYT in the location bar.

Stylish

Thanks.

I tried Stylus, which is WebExtensions compatible. As far as I recall the beta was not effective for things such as these:

– for those UI enhancements and others, I have styles that work with Stylish but not with Stylus. GitHub · Where software is built might include an explanation.

Tab Groups

Development and Maintenance of TabGroupsManager extension – expect an update there about last month’s proposal, TabGroups Manager revived: rewrite for WebExtensions.

As far as I can tell there’s no group functionality. See below:

Vertical tabs

https://addons.mozilla.org/firefox/addon/tab-center-redux/

– to the side; not a substitute for Tab Groups.

For compatibility with Tab Groups, I chose Vertical Tabs Reloaded.

I sometimes use the sidebar of Tab Center Redux alongside the sidebar of Vertical Tabs Reloaded, only because there’s no Showcase with 55 and the FAYT results in Tab Center Redux are more visually appealing than the Switch to tab feature of the location bar. Visually appealing but limited to one window.
