Settings are not saved Rated 3 out of 5 stars

Can't change the settings. Too many h-levels and respective scrollbar ballons.

Just a thought Rated 4 out of 5 stars

Would do well as a page marking, bookmarking or referencing tool. Like (Dog Ears) but better.

Useful Rated 4 out of 5 stars

Very handy indeed. Does what it says, and everyone should give it a try to see how it changes the browsing experience.

Excellent! Rated 5 out of 5 stars

Just the thing for long content-filled pages. One of those ideas where one just wonders why no-one has done it before!

Hope to use "instant scroll" instead of scrolling slowly.

Check the options window of the extension. You need to uncheck setting "Animate scroll when a marker is clicked"

easy great idea, works also with dark style. If is but deactivated icon is unvisible.

Happiness is a New Add-on :) Rated 4 out of 5 stars

Hi - Love this! I do a lot of reading of lengthy documents online. Very welcome aid. I will be using it often. Like everyone I have some ideas.Maybe the tab stack can be movable, from right to left, in order to avoid overlapping on nav towers.Also, I wonder if there can be links to 'definition terms' and even paragraphs.I have 2 other extensions by you, and I know you are a busy guy. So thanks for all your hard work!

Very good work so far, but could be even better Rated 4 out of 5 stars

I have only used it for a few hours, but I must say I will probably keep it installed for a long time. That said, I would like a few extra options to make it perfect IMHO:

1. An option to hide all the tooltips once I make my selection. That would me one click every time since I don't like to keep it on all the time.

2. An option to tweak (or eliminate) the scrolling animation. I find it to be a bit slow in the case of my desktop and REALLY slow on my old netbook.

3. Another useful option (as other reviewers have already mentioned) would be to only show the "tooltip area" only when the mouse pointer is over it. That would almost eliminate the need for a toolbar toggle button. How wide should the area be? I would make it exactly as wide as a minimized tooltip).

4. An option to invert the tooltip colors based on the current website background color. As an example, draw black tooltips with white text if the current background is white. This should be possible to accomplish using SVG filters: http://j.mp/Onut5C (apparently the "invert" CSS keyword is not supported in FF).

5. An option to change the size of the tooltip text. Bonus points if I can specify the font. :)

6. Add tooltip borders to help separate them from the actual page content.

Thanks and keep up the excellent work!

Shortcut Key ! Rated 2 out of 5 stars

Great! Rated 5 out of 5 stars

On content heavy sites, a lot of markers get clustered together. It's still kind of manageable as the markers are a bit transparent so I can see behind it. However, it would be even better if the markers actually move to the "top layer" as you mouse over them so that the labeling becomes readable.
P.S. Just thought of something. Adding a feature to have the markers only appear when hovering near the scrollbar and disappear when not would eliminate the need for a button that takes the markers away completely.

Helpful for long web pages Rated 4 out of 5 stars

With this addon, I can jump to each section without dragging the scrollbar. This is very useful on such cases: I know the page includes a specific topic but I don't know where it is. Different from in-page search, existing summaries (headings) are shown visually beside the scrollbar.

For Japanese (and Chinese, Korean) people, I recommend you to customize the hidden preference "extensions.contentscrollbar.textlength" to "firstTenCharacters". By default it is "firstThreeWords" but it works same as "entireText" for CJK webpages because CJK terms don't include white spaces to split words in most cases. In such cases, "firstTenCharacters" will work better than the default. (I want to enlarge the number of max characters than 10, but sadly it can't be done...)

One request, it will make me happy that auto-hide feature for this addon. Even if I want to see contents near the scrollbar, there are links made by this addon so sometimes they cover the contents. If those links are hidden (or shown with very small width) by default and become expanded to full size when I move my mouse near the scrollbar, they won't interfere with my view.

By the way, I currently use this with another addon "Custom Buttons" ( https://addons.mozilla.org/firefox/addon/custom-buttons/ ) to add a toolbar button to toggle functionality of it.
My button "Toggle Content Scrollbar" is defined with following codes:

Initialization Code:
var key = 'extensions.contentscrollbar.enabled';
var Prefs = Cc['@mozilla.org/preferences;1'].getService(Ci.nsIPrefBranch);
this.type = 'checkbox';
this.autoCheck = false;
this.checked = Prefs.getBoolPref(key);

Code:
var key = 'extensions.contentscrollbar.enabled';
var Prefs = Cc['@mozilla.org/preferences;1'].getService(Ci.nsIPrefBranch);
Prefs.setBoolPref(key, !this.checked);
BrowserReload();
this.checked = Prefs.getBoolPref(key);

----
Japanese version:
これがあれば、スクロールバーをあちこちドラッグしなくても、ページ内の各セクションに一発でジャンプできます。そのページに何か探している情報が含まれている事は分かっているけれども、どこにあるかは分からない、という時などに便利だと思います(自分は、技術文書などでそういうことがよくあります)。ページ内検索と違って、ページ内にある要約となるテキスト(見出し)がスクロールバーの横に表示されるという点が特長です。

日本語圏や中国語圏、韓国語圏の人は、隠し設定の「extensions.contentscrollbar.textlength」を「firstTenCharacters」(先頭10文字だけ表示)にするのがオススメです。初期値の「firstThreeWords」(先頭の3単語を表示)は、単語の区切りに空白文字を使わない言語では「entireText」(全文を表示)と変わらない結果になってしまいますので。(ちなみに、文字数を10より増やすということはできないようです。残念。)

なお、自分はこのアドオンの機能の有効・無効を簡単に切り替えられるように、Custom Buttons( https://addons.mozilla.org/firefox/addon/custom-buttons/ )というアドオンと併用しています。新しいユーザ定義ボタン「Toggle Content Scrollbar」を作成して、Initialization CodeとCodeの内容を上記の通り設定しています。

version 0.2.0 is available

Try the new 0.2.0 version (https://addons.mozilla.org/firefox/addon/content-scrollbar/versions/?page=1#version-0.2.0) that allows you to
- Add a toolbar button and let the markers show/hide for the current tab easily.
- Set extensions.contentscrollbar.enabled = minimized to see the minimized markers

Rated 5 out of 5 stars

Request can be set to turn off &on the Open button function :)

And free to set the URL filter conditions.
