Ublock Origin is an obvious one, but I also can’t stand not having Foxy Gestures anymore. It adds customizable mouse gestures, so you can set it up to have easy swipes to go back a page, reload a page, close a tab, etc, and it feels wonderful and smooth to use compared to just using the traditional buttons to do everything. Honestly it’s kinda wild to me that this isn’t more popular now that people are so used to phone gestures. It’s good for the same reasons!
It’s quite simple. Create a pocket account at https://getpocket.com
Add some articles or Web Serial chapters to your pocket (easier with the Save to Pocket extension)
Add the Pocket account to your Kobo.
Sync your kobo.
It’s such an under advertised feature of the Kobo devices.
Better but personally I don’t like creating accounts on the kobo, would rather do ond desktop: https://help.kobo.com/hc/en-us/articles/360017763753-Use-the-Pocket-App-with-your-Kobo-eReader
💯 - it’s one of the reasons I chose to get a Kobo over a Kindle, I’ve mentioned the feature to friends and they had no clue that they support Pocket.
