If you want ThunderBrowse to also have zoomed content (View<Text Size) you can install TBZoom. It includes a feature I probably won’t add to the official build of ThunderBrowse due to its many calls might eat “too much” RAM on older systems. It doesn’t eat alot, but then again, I really didn’t put it through any tests.
Like the other extensions, it’s a freeware extension. Unlike the others, YOU CAN’T DISTRIBUTE IT. No putting it up on download mirrors, nothing. No means NO. I really don’t want to have to deal with any updates I might make and have to ping every freakin’ body. I would also like it if you linked to this and NOT to the direct file. I have my reasons.
Other than that, it’s about 3KB and it’s at Version 0.2 which you can totally download/install here.
