Works for me on Ubuntu22.04 on Firefox. One problem exists where i have to click any newly loaded twitter page in order to interact with the page at all.

Used to work perfectly but now causes duplicate text and other glitches due to Twitter update.

Extremely convenient for just going through things like witch hunt threads and blocking everyone with a pitchfork in their hand.

Unfortunately, it makes twitter gradually slow to a crawl as I scroll down. I believe there may be a garbage collection issue or memory leak when scrolling down long feeds.

Another, small bug, is the first time the icon is clicked when viewing a page, it will open the ... menu on that tweet instead of blocking. After manually blocking once it works normally.

Doesn't work on the likes of a tweet. For example, if you open a tweet and then click the likes number, it pops up a window with all the people who liked it. The block button does not work there.
