The tabs permission is only needed to access a tab's url, title, and favIconUrl. This information is available at the top of this article: tabs - Mozilla | MDN.

Is those properties really used by this extension? If not then you could remove the permission from your manifest without affecting the extension.

In Tab Tree "Unload Tab (X)" doesn’t unload tab, but create new tab.

In Firefox 61.0.1, with Tree Style Tabs 2.4.24, and UnloadTabs 0.8.1, the "Dim unloaded tabs" checkbox works as expected at first. But after exiting and restarting the browser it loses its effect until I go back into the extension preferences to uncheck the checkbox and check it again.

The Options tab for UnloadTabs in the Addon manager is completely blank. I've tried un- and reinstalling UnloadTabs but the options tab is still blank. The addon does work though, but I can't change any of the current values. The options weren't always missing. I've used the addon for quite a while with no issues. Any suggestions as to how I can get the options back?

1. It would be nice to show in tab bar which are unloaded by changing the color of the tab

Situation:
When using the URL-bars "Switch to Tab" feature from new tabs (never navigated), Firefox closes the tab and intentionally switches to a possibly unloaded tab.
UnloadTabs prevents that:

Add localization capability.

Could you add the option to just unload selected tabs that were selected using the browser.tabs.multiselect ?

there are no preferences displayed and when i click unload tab on any one of the tabs i get a notification like this. does librewolf prevent the extension from loading because it's a hardened derivative of firefox or is the extension having some bugs?

I want the context menu options in Tree Style Tab but I'd rather not have the tabs dimmed, as I already have CSS to tell unloaded tabs apart from loaded ones.

It should choose an unloaded one nearby instead.

Hi,
love the extension - the only thing that I miss is a confirmation before actually re-loading a tab (e.g. a button on an unloaded tab).
Would it be possible to implement such a feature?

Use case:
when I have few unloaded tabs with the same title but different url's (e.g. same domain, different sub-pages) and I want to re-load one specific tab among them,
then I don't know which tab is the one by tab's title - but I will know if I see the url.
So I go through these pages one-by-one to check their url's.
Right now, each page is automatically re-loaded whenever I click on it (whether I want it to re-load or not).
Ideally, I would be able to choose whether I want to reload it or not (and look further for the one specific tab I'd like to reload).

E.g. all unloaded tabs could show a content similar to:
"
This tab is unloaded by UnloadTabs extension.
The tab's url is: https://www.example-url.com/sub-page/even-more/detail.html .
Hit the reload button below to reload this tab.
[RELOAD]
"

I know this feature is "implementable" - I don't know how "feasible" it is to implement. :)
While I'm reluctant to point to another extension, there's only one that I found (for FF-Quantum) that has this feature: "Freeze, Tab Suspender". (But it doesn't provide any automated tab-unloading, so doesn't provide any value to how I use FF.)

Hi,

I think findClosestNonPending should only search tabs in the visibleTabs list, and if no loaded tab is found, it should just return null. Then we can change this into

gBrowser.selectedTab = findClosestNonPending(tab.parentNode.children, tab) || 
                       gBrowser.addTab();

Because otherwise the browser will jump into a random tabgroup which is a bit confusing.

At the moment, when CTRL + Clicking multiple tabs and using an unload tabs function will only work on the tab that is focused (the one you're currently in), as opposed to your selected tabs. I think it would be pretty cool to have it work with selected tabs as well. For example, you can select which tabs you want as active, and then right click unload other, or select a bunch of active tabs and suspend them all together, less binary than 1 tab or all the other tabs, while still being able to keep the same context menus.

There's a shortcut for unloading the current tab, but didn't find any for unloading all other tabs. I think that would be useful.

I'd like to suggest adding options to unload all tabs to the left, to the right, and to mark tabs to not be unloaded

The context menu does not show up when tabs are right clicked until then. In addition to the missing context menu on the tabs, there's also this 500 error that appears at the bottom of the add-on's page where the options usually go, also until it's been disabled/enabled:

I had to replace

@-moz-document url(chrome://browser/content/browser.xul) {

with

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul");

Prior to FF Quantum I used the "suspend tree" option of the Suspend Tabs + Tree Style Tabs combo, is there any way similar action could be added?

Simply unloading all tabs in the selected container would be close enough for my uses.

Hello first I wanted to ask if this addon is on AMO and if there are plans to update it for firefox 57+

“Unload Tab” and “Unload Other Tabs” have no mnemonic. All the standard Firefox items do^†, and I’d say that in general everything should. This makes batch unloading quite slow to accomplish.

U is taken by “Undo close tab”. I’m thinking L, in “Unload Tab”, or X, i.e. “Unload Tab (X)” (I think some platforms hide the “ (X)” part somehow? Like with “Inspect Element (Q)”?).

I’m not so fussed about Unload Other Tabs. You’ll only ever use it once at a time.

^† OK, except for “Open in new non-e10s window” if you’re on Nightly.

Mozilla announced that starting in Firefox 57, Firefox will no longer support add-ons that are not WebExtensions.

Is it possible to convert Unload Tabs to be a WebExtension, so it can continue working in Firefox 57 and beyond?

B remains unloaded but retains the loading icon indefinitely, until manually selected and loaded.

Happens with the "Prevent Firefox from loading unloaded tabs" option enabled.

Tried to use versions from 0.7.2-b1 to 0.7.2 - still not working (no "Unload" items in the context menu).
There is an error in browser console:

SyntaxError {
  fileName: "resource://gre/modules/commonjs/toolkit/loader.js -> resource://unload-tabs/main.js",
  lineNumber: 107,
  message: "missing : after property id",
  stack: "@resource://unload-tabs/main.js:107:undefinedrun@resource://gre/modules/commonjs/sdk/addon/runner.js:147:19startup/</<@resource://gre/modules/commonjs/sdk/addon/runner.js:87:9Handler.prototype.process@resource://gre/modules/Promise-backend.js:933:23this.PromiseWalker.walkerLoop@resource://gre/modules/Promise-backend.js:812:7this.PromiseWalker.scheduleWalkerLoop/<@resource://gre/modules/Promise-backend.js:746:1"
}

Although 0.7.1 seems to be working fine in FF ESR 45.

Probably not a hard fix. Manually right clicking a pin and unloading it works. I guess they are kept in a separate list

they should be https://addons.mozilla.org/de/firefox/addon/unload-tabs/, but you’re missing the dash

Am I doing something wrong? From the addon description you'd expect this to work by default. Thanks! 😀

I do not expect this to change Firefox’s behaviour. If the next tab that would be loaded is pending, so be it. I don’t want this extension to interfere.

Still, the behaviour I’m observing is I think not even the behaviour you intended.

I have lots of tabs. Here’s an extract:

• 1, loaded
• 2, unloaded
• 3, unloaded
• 4, loaded
• 5, loaded
• 6, loaded
• 7, loaded

When tab 6 is focused and I close it with Ctrl+W, I expect tab 7 to be focused, as it is in stock Firefox.

Instead, tab 4 is focused (!). Or in other similar circumstances, tab 5 (the previous tab).

I just want normal Firefox behaviour. I just want the TabClose event listener to be removed. Can changing the behaviour please be shifted to an option (and probably fixed so it matches what Firefox does more closely)?

I believe this extension should be focused only on unloading tabs.

It would be nice to have toolbar buttons.

By the way - thanks a lot for making this add on. Super helpful!

If I unload all the tabs, it's a bit disruptive for the page to not unload. Have to press Ctrl+T, go back to tab, and then Unload it.

It would be a much smoother interaction if there was an option for the extension to open a blank New Tab, if every tab is unloaded.

Bug 1450382 (loading discarded/pending tabs removes the favicon) was marked as solved (RESOLVED WORKSFORME). Can you confirm that described problem disappeared?

Once in a while I find I can no longer unload tabs. Usually in these cases I go to about:addons and try to open the preferences page for unload-tabs. I get a page titled "Invalid context" with this text:

500 Fatal Error
This extension page can't be displayed in private windows, container tabs or other non-normal contexts.

Please try to open moz-extension://11a02ba0-9893-4795-9a93-437361cc5314/UnloadTabs?originalTab=220#options in a normal tab. 

But this is a normal tab, not a container. I try to open that URL in another regular tab and get the same error.

If I disable and then re-enable the addon it starts working again: I can unload tabs again and I can get to the preferences page.

Under unknown conditions, a MangaDex tab won't be properly unloaded, and attempting to use ANY tab as normal after will cause the content to flesh a dull gray with a low frequency that gradually goes up until no tab of the same window can be accessed properly, displaying the Firefox default "loading content" circle as if the tab froze.

Hi, just wanted to mention it would be nice to have a third menu option that unloads tabs in all windows rather than only the current window. This would be useful when there are 10+ windows open on multiple desktops, and the Firefox memory usage is high.
