Tab Session Manager vs uBlock Origin

Tab Session Manager has no write-up on Specifiction yet; its figures are above.

uBlock Origin is a free, open-source content blocker for desktop and Android versions of Firefox, as well as Chromium and Thunderbird versions. It blocks ads, trackers, coin miners, popups, anti-blockers, and malware sites by default. Several filter lists are built in, and users can add lists and hosts files or create custom rules using EasyList syntax with uBlock Origin extensions. If blocking is too broad, users can disable preselected lists. The basic and advanced popup interfaces include a per-site point-and-click firewall. The project’s stated purpose is to help users neutralize privacy-invading methods in the browser, and it is described as CPU- and memory-efficient, fast, and lean. It works best on Firefox and also supports Chromium-based browsers, including Edge and Opera. In Thunderbird, it affects feeds but not email. The project advises against running it alongside another content blocker. It is licensed under GPL-3.0/GPLv3, and enterprise deployment documentation is available.
