Description

Custom Style Script customizes the way a webpage looks or behaves, by adding a small JavaScript or CSS code. You can also specify a URL to add the code or add it to all pages. Key features: 1. Add custom JavaScript codes or styles (CSS) to a specific page or all pages. 2. Clicking on the toolbar icon allows you to disable or enable the addon. 3. Each code item has several options to adjust (see options page for details). 4. You can add several code items and active or inactive them separately. 5. An example of how to add a code is available in the add-on's options page. 6. Before adding the code (JS or CSS) please make sure you have validated the code. 7. Online JS or CSS links (i.e. jQuery or bootstrap) can also be added to any page. See add-on's options page for details. Note: to report bugs, or request a feature, please visit the add-on's homepage (https://mybrowseraddon.com/custom-style-script.html) and fill the bug report form.

Unfortunately this plugin works seldom as intended. "Reload the active tab" seems to work randomly. Scritpt is executed sometimes. The Idea of the plugin was good, but its implementation is bad. Maybe if you are using just one tab or so... I wanted to save time, but this plugin steals time

No longer works. Used to be great way back in the past, so I thought I would give it another look. Attempted a simple CSS change which a similar extension can handle no problem, no change. Also as another reviewer mentioned the reload button does not work, it seems to affect all the tabs in some weird way, I could hear the active youtube tab in another window play a quick audio cue on a paused video, but no reload on the active tab i clicked the popup from. It just seems entirely broken all around.

It doesn't work on youtube.com now. It worked before. It shows the following exception: TypeError: Failed to set the 'src' property on 'HTMLScriptElement': This document requires 'TrustedScriptURL' assignment.

Works fine, but... if I add more than 1 script it is impossible to scroll down, the window of the extension stays static and the subsequent scripts are impossible to see.
