Additional bookmark button in Chrome-based web browsers

Question

I would like to ask the question Simple method to store additional set of bookmarks for Firefox browser, but for the Chrome-based browsers instead of the Firefox browser.

I don't want to send certain webpages to the regular browser bookmarks because then they will appear in the location bar suggestions. (I could turn off bookmarks for location bar suggestions, but I want my regular bookmarks to still appear.)

(I paraphrased)

Is there a software that makes a private set of bookmarks that can be controlled from a web browser?

Requirements:

• Must be offline (does not store bookmarks "in the cloud")
• Must handle thousands of bookmarks (acceptable limit is about 5000)
• Gratis or very low cost
• Windows compatible

Not needed:

• Encryption
• Passwords

Already tried:

• Save-To-Read - Bookmarks still appear in location bar suggestions. Also difficult to remove bookmarks.

Answer 1

chrome-pseudobookmark, For Chrome

I wrote this Chrome extension. It's very simple (especially the v1 release, only ~700 bytes) and easily customizable through the source code.

It creates an alternative bookmarking mechanism and is probably best used as a temporary holding space because it's faster to use than normal bookmarks.

Successes:

1. Gratis
2. Windows compatible
3. Works offline

Failures:

1. Only supports 512 items
   • But if you change chrome.storage.sync to chrome.storage.local in the source, you could have unlimited storage.

Other positives:

1. There's no possibility for duplication.
2. The interface can be tweaked for custom export options.

This Chrome extension will create an additional Add Bookmark button with its own separate storage location.

Ctrl+Shift+A bookmarks the active page.
Ctrl+Shift+E opens the options page.

Press the toolbar button to bookmark the page.
The button disappears on bookmarked pages.

Options Page

• Ctrl+A inverts item selection.
• The options page presents bookmarked URLs as hyperlinks.
• Click/click-twice to select/deselect items.
• Pressing the del key, triggers the delete function of selected items.
  • One confirmation dialog will appear before permanent deletion.
• There's an import/export function. It works with item selection. Import works with JSON. Export works with JSON/markdown.
  • JSON Format: {url : {'favicon': faviconurl, 'title': title}}
• There's a delete button.
• There's an invert selection button.

Notes

• I don't think extensions like this should be used for maintaining browsing data. Only for producing quick lists.
• It doesn't have folders.
• I might write a python component that duplicates the extension by changing its name and color scheme, to provide multiple toolbar buttons and a folder type functionality. That's only if the Chrome API doesn't support multiple activepage buttons.
