► Intro
FLST
provides a more natural browsing experience with features and options
missing from Google Chrome.
FLST
maintains tabs with MRU ordering (Most Recently Used);
when the current tab is closed, the Last-Selected-Tab
is displayed (or "Focused").
To suit user choices, the other
FLST
features are designed as configurable options.
When this extension is first installed, options are enabled.
Click the other buttons above for option details.
► Method
Chrome assigns a numeric ID for each tab (eg 111, 14, 79).
During various tab-related events,
FLST
updates sets of tab-IDs with MRU ordering.
Tab ordering is privately maintained for each Chrome window.
Migrating tabs between windows is also supported.
► Background
After Google Chrome was introduced, many features from Mozilla Firefox
and FF extensions were desirable for Chrome.
By 2011, a new independent
FLST
extension was created for Chrome, partly inspired by features
from a mix of now-former Firefox versions. (also see
Limitations, next button)

Limitations:
Since 2011 / Chrome 8.x and probably earlier,
when the current/displayed tab is clicked,
Chrome ignores that event and does nothing.
Different methods are required to trigger
Tab Flipping.

All
extensions including
FLST
cannot prevent others from altering tab-related activity.
So far all issues reported here have been
caused by another enabled extension.
To resolve any issues, first disable all other extensions,
quit and restart Chrome, then retest.
Re-enable other extensions only 1 at a time between tests.
► ALERT!
Google announced Manifest V3 for extensions
– with drastic changes –
and plans to drop Manifest V2 support, estimated Jan 2022.
Those changes will disable countless extensions and some
may return after major rework.
Really consider donating to FLST
and other extensions well before Jan 2022.
(Option)
Tab Flipping:
When there are
2
or more tabs, clicking the Extension Icon

will flip (or toggle) between the current-tab and the Last-Selected-Tab.
The same flip/toggle can be done with a keyboard shortcut
(example: Alt+N).
Chrome supports configuring shortcuts to most
Ctrl+ or
Alt+
combinations.
Instructions are also provided during installation.
Older extensions used a content script for shortcuts like F9 or F10,
though Chrome support was always incomplete and now gone.

(Option)
New Tab Select:
After a right-click on a regular link and choosing
,
also select/display the new tab.
When a tab is opened with that method, the Chrome standard creates a new tab
usually with content, but the current tab remains selected/displayed;
the user normally has to click the new tab as well.

New Tab Location:
After a right-click on a regular link and choosing
,
place the new tab on the far right.
When a tab is opened with that method, the Chrome standard places
the new tab on the immediate right.
The difference is apparent in the common case
where the opener / current-tab is
not the furthest right.
►
Note that Chrome places new blank tabs (Ctrl+T)
and some chrome:// tabs on the far right;
this extension does not alter that behavior.
