Tree Style Tab
This is an addon for Firefox providing tree-like appearance for the tab bar.
Frequently REJECTED requests/proposals
I'm very sorry but this addon is strongly concentrated about "tree of tabs", so features not related to "tree of tabs" are out of its purpose. Such features won't be added, even if many people love it.
Moreover, basically this is my private project and the prime user is me. Of course I'm ready to merge pull requests by any contributor, but I possibly stay it unmerged when it can break my private usecase. Then I strongly recommend you to fork this project for your usecase freely.
There are some major requests which are reported multiple times but I marked them "won't filx". For example...
Full support for the horizontal tab bar or non-indented vertical tabs
Basically this is designed to provide vertical indented, deeply nested tree of tabs. There is only limited support for non-tree mode. If you just require the vertical tab bar and you never use "tree of tabs", then please try other alternative addons:
And, horizontal tab bar is just a bonus. If you are a heavy user of the horizontal tab bar, then bugs appearing only on it won't be fixed by me. Instead please fix it by your hand and send pull requests to me.
Tab Mix Plus, especially its own session management featureHigh compatibility with
Supporting TMP is very hard, because TMP-enhanced Firefox is totally different from plain Firefox - they are practically different applications. So, it requires hard work to support both applications constantly. Moreover, unfortunately I have very few motivation to maintain TST for TMP, because I'm not a user of TMP. If you are using TST with TMP and get some troubles, those bugs won't be fixed by my hand aggressively.
Instead please fix problems you met and send pull requests to me.
Pale Moon is based on old Firefox but TST supports only recent versions of official Firefox. Supporting for Pale Moon means supporting for very old Firefox. To keep codes cleaner, I have to remove obsolete codes only for old versions of Firefox.
If you require TST for Pale Moon, sorry but please fork this project and rollback to an old revision which can work on Pale Moon.
It can't be done because TST's vertical tab bar is the Firefox's tab bar itself. In other words, TST just rotates the orientation of the tab bar from horizontal to vertical and completely reuses Firefox's tab bar. It is not another new sidebar, TST doesn't hide Firefox's original tab bar. It is still there.
If you really want to show both horizontal and vertical tab bar, then please uninstall TST and install any other addon which provides a custom sidebar panel to show tabs vertically.
Quick access to the configuration dialog, Adding new minor (trivial) options, and so on
I have no plan to add a custom menu item to go to TST's configuration dialog - sorry but you have to go to the dialog via Firefox's Addons Manager always. If the configuration dialog is frequently required in your daily use, there is something implicit problem which must be solved in another way. Instead, please describe why you need such a fast pass to the configuration dialog. After the actual problem is solved, you won't need such a menu anymore. In other words, adding such a menu can disguise fatal problems which really should be solved.
And, high customizability for details of features is out of TST's purpose. I hope to provide only very required options which are truly un-omitable. Too many optional features will kill this project, because they will cloud the important concept of TST and will bring together people who don't like my core vision about TST. Instead, sorry but please fork this project and modify it for your usecase.
In most cases - subjectively 99%, new tabs from links may be related to the source tab, and tabs from bookmarks may not be related to the current tab. For other rare cases - if you want to open the link in new sibling tab, or you want to open a bookmark as a child tab of the current, then you can do it by dragging a link or bookmark and drop it onto a tab or between tabs. Natural operations for GUI objects shoud be optimized for most major usecases.
Too high customizability for such rare usecases will just make you happy, but others including me won't - they are just confused that "why such too much choices are here?"
Firefox already have very large number of keyboard shortcuts, and other addons also provide their own keyboard shortcuts, I cannot find out safe combinations for my features. So I gave up and decided to provide only APIs for other addons. Please use generic addons to customize keyboard shortcuts which can define custom actions based on scripts. Sorry. See the code snippets also.
By the way, "auto hide tab bar" feature doesn't provide any its own keyboard shortcut to toggle it because the feature is included in TST mainly to simulate Firefox's default behavior in the fullscreen mode (started by the
F11 key). Is there any keyboard shortcut to show/hide the navigation toolbar?
sorting child tabs, auto-modification of tree, renaming of tabs, and so onHigh-power management of tree, like
I believe that generally "tree of tabs should be a visualized history of web browsing", because they are built on relations where you came from. Possibly such a tree is facially chaotic, but it just mirrors your actual footmarks, so you'll easily find out where is the target tab based on a map in your mind. Moreover, those relations themselves may let you recall forgotten idea you thought while you were browsing those tabs.
On the other hand, sorted tabs based on URLs or something will be beautiful - but that's all. Such sorted tabs won't help me - I'm very forgetful. In other words, I just need something which memorizes my chaotic mind as-is.
By the way, my another addon Multiple Tab Handler will help you if you frequently modify tree by drag and drop. It provides ability to select multiple tabs by Ctrl-Click or Shift-Click and you can drag selected tabs at once.
color, height, visibility of the scrollbar, transparency of tabs, and so onConfiguration UI to change appearance of tabs in the vertical tab bar, for example,
Instead please use the
about:config. TST should have configuration UIs only for something it can't be done by any other existing customization feature.
If Firefox introduces new preference to disable tab animations, I'll apply it for TST too. Otherwise I have no plan to implement such a "no animation mode", because it will make TST more far from Firefox's plain codes. Now I have only a few resources to maintain TST, so I don't want to increase the risk that I give up to update TST for future versions of Firefox which will be continuously modified.
Thanks, but sorry, I have no plan about any donation because I hope to keep me as the prime user of this project. I hope to keep having a privilege to say "no" about requests not matched to my vision. My hand is already full to maintain this addon for my usecase.
If you fixed a bug you met, please send a pull request - I'll merge it. If you have different plan about TST, please fork this project freely for your purpose, if needed.
I think TST never been published as a "full-reviewed" addon on AMO, because there is one unavoidable issue: TST doesn't match to the policy of AMO.
In 2010, AMO editors decided to reject Tree Style Tab and some my other addons as "bad" addons, because they were against AMO policies - mainly, they used many
eval() to inject custom codes into functions defined by Firefox itself. Because there are less APIs for addons like TST, I still have to use
eval() to do it. I wrote an objection for this topic, in years ago.
If the review policy was changed or relaxed, I'm ready to request full review again. Otherwise, my request won't be accepted...
To be honest, I agree that TST possibly should not be published as a full-reviewed addon, by AMO policy. TST is too fragile from many tricky hacks. Moreover, actually, too many
eval() make my addon hard to be reviewed. So, I even think it is better that my addon is kept in sandbox with quick updates, than slow updates from every full-review processes taking much time.
