For instance, in the settings page for Tab Session Manager, you can click an upload button to upload JSON session files from your device to the addon. I looked up if UBlock Origin Lite (the re-implementation of UBlock Origin with Manifest v3) supports custom filter lists and all the results said no it can’t due to the limitations of Manifest V3. OTOH I found a StackOverflow post and Google Groups discussion saying its possible with the filesystem API.

    From an update from last week:

    Firefox, however, has no plans to deprecate MV2 and will continue to support MV2 extensions for the foreseeable future. And even if we re-evaluate this decision at some point down the road, we anticipate providing a notice of at least 12 months for developers to adjust accordingly and not feel rushed.
