Freeze the currently active tab?

[freddyb]

The currently active tab can't be frozen.
What to do, when user tries to freeze currently active tab?
We could navigate to the next tab and then freeze the previous one, suggests caspy7

Could this be mentioned in the extension description? It means that single tab windows cannot be frozen, and since the extension doesn't give any indication that it failed to freeze the current tab*, I assumed something was broken when the tabs still showed up in about:performance.

*you'd know it failed if you knew that the extension blanks out discarded tabs, but that it does that (instead of maintaining the current DOM) isn't obvious before you've used it successfully.

Hm, I think this is mostly a shortcoming of the provided APIs. No foreground tab can ever be discarded :/

Do you want to make a more specific recommendation given the existing description?

[phoenix-meadowlark]

Yeah, I was guessing as much :/

Maybe something like "Note: tabs in the foreground of a browser window cannot be discarded (and trying to do so will have no effect)."?

If the user clicked to discard the current tab, this add-on could first switch to another tab, and then freeze that previous tab. The benefit: This would allow us to have a toolbar button - instead of right click and going down the context menu.

As to which other tab to switch to, suggest having a preference/config option:

• the tab nearest non-discarded tab to the left, or
• the tab nearest non-discarded tab to the right, or
• the previously selected tab - out of those the most recent one that is not discarded, or
• open a new tab.
