I hope that in the new version the new features will become optional.
Hard to figure out, but it works WELL! It's WORTH the learning curve, though, for just about NOTHING else can do what it does as well as it does. TOP-NOTCH! Current users need to be aware that Twitter.com recently changed URLs to point to the big jerk's favorite letter .com, AND YouTube just changed the code behind it's CSS; you might need to tell your scripts to affect the URL [ h t t p s www . youtube-nocookie . c o m / * ], ( you need to fix the formatting of that URL in the obvious way, of course. ) That's the URL I needed to use to format the font on the captions in the YouTube player to an easy-to-read font on my local system.
Пользуюсь несколько лет, хоть не являюсь специалистом по JavaScript и CSS. Просто случайно нашёл пару примеров, которые переделал под свои нужды. Вопрос уважаемому автору: подскажите, пожалуйста, где можно посмотреть ещё какие-либо скрипты или примеры, которые люди писали для вашего расширения? Может на каком-то форуме или сайте кто-то делился? Или вот даже тех кодов, что у Вас на скришотах программы...
js code has not worked sinse recently I hava never altered my code and browser, and anything error don't exist how can i solve? I don't even know what the problem is
I am having issue. JS code is loaded but custom button that I add with onclick function is not working. issue: "copyToClipboard is not defined"
Useful extension for removing unwanted limitations, adding missing features, and adjusting designs!
After 3.0.5 updates it seems that css load timing is quite changed. How can I revert it?
Скрипт перестал работать, запустил режим разработчика, но всё безуспешно. Нужны ли ещё какие-нибудь дополнительные настройки?
Спасибо за расширение очень помогает настраивать сайты для нормального использования.
