Open Bookmarks Slowly Peter Simonyi מאת

The built-in “Open All in Tabs” on bookmark folders is pretty handy — but it opens bookmarks all at once; if you have very big folders to open, it can slow down Firefox and the pages might not load fully.

This extension adds a context menu item “Open All Slowly” for bookmark folders. The bookmarks are opened a few at a time, waiting for previously-loaded bookmarks to finish first, so that they all have a chance to load completely without slowing things down too much. If a tab doesn’t load the page or gets stuck for a long time, it will try again a couple of times. You can keep browsing in another window or do something else while bookmarks are loaded in the background. There is an option to get a notification when the bookmarks are all loaded.

Permissions:

• Read and modify bookmarks: this extension won’t modify your bookmarks, but it does need to read them to open them.
• Access browser tabs: it checks whether the current tab is a new tab that can be reused for the progress page. Surprisingly, the other tab manipulation doesn’t actually require this permission.
• Access browser activity during navigation: it monitors tab loading to detect tab redirects, load errors, and generally try to make sure all the bookmarks load.
• The “Open All Slowly” item is added to the context menu for bookmark folders.
• If you enable the option to show a notification when loading is finished, Display notifications to you is requested.
