oss-browser | OSS Browser provides functions similar to Windows Explorer | User Interface library

I am working with Selenium Webdriver with Cucumber. My tests work as expected with that combination. In order to achieve cross-browser testing, I added TestNG framework. To verify that my cross-browser test was working good, I ran it with TestNG alone, without Cucumber. It ran perfectly in both Chrome and Firefox browsers.

According to the docs, a react synthetic event is a

a cross-browser wrapper around the browser’s native event. It has the same interface as the browser’s native event, including stopPropagation() and preventDefault(), except the events work identically across all browsers.

Why is it important that the events work the same in every browser if their interface is always the same (as implied by 'It has the same interface as the browser’s native event')? Dose the fact that React uses event delegation make this nesessary somehow?

What is the meaning of context in the passage below?

The first rule is to deny all - don't put untrusted data into your HTML document unless it is within one of the slots defined in Rule #1 through Rule #5. The reason for Rule #0 is that there are so many strange contexts within HTML that the list of encoding rules gets very complicated. We can't think of any good reason to put untrusted data in these contexts. This includes "nested contexts" like a URL inside a JavaScript -- the encoding rules for those locations are tricky and dangerous.

If you insist on putting untrusted data into nested contexts, please do a lot of cross-browser testing and let us know what you find out.

This passage is taken from Cross Site Scripting Prevention - OWASP Cheat Sheet Series.At there,you can find rule #0 through rule #5.

I've been developing a cross-browser extension (for Chrome, Firefox, Opera, etc) that runs a script every time the user goes to a new page on Youtube. Since Youtube uses the History API's pushState to navigate to a new page, injecting the script declaratively only works when a page is reloaded or the URL is explicitly entered into the address bar. To get around this, I used onHistoryStateUpdated from the webNavigation API to inject the script programmatically (as explained here).

manifest.json:

I'm having some issues with iOS ignoring a combo of align-self:flex-end and margin-bottom: 8px.

On Android devices, various Windows versions with Chrome and Firefox, and Chrome on macOS, #totalImg is displayed as I'd expect it to be - bottom right corner, slightly raised.

On Safri for macOS and Safari and Chrome for iOS, #totalImg is glued to the bottom.

See the following image for current behaviour:

I'm aware that I could get consistent cross-browser behaviour by applying bottom: 8px, but that seems to be working just in my test case, and fails in production, depending on the screen width of Android or iOS devices. For example, on Chrome for Android, with bottom: 8px, #totalImages can end up in the middle of its parent div, or well below it.

I am, basically, answering the question here, but perhaps someone has another idea. You can use an onpopstate function, but I find this much simpler to deal with and cross-browser compatible, even with old browsers.

I have a drop-down select box that is populated by a database query. In this case, it has only found one relevant city. Selecting that city, which takes the user to another page, then pressing the Back button, returns the user to the page with the selection still in the selected state, which prevents it from being selected again, unless another selection is made first. So I added an onClick event to change the Selected default before leaving the page.

HTML

I'm trying to create the following scroll behavior (in React): each individual 'tick' of the scrollwheel scrolls in multiples of 100 pixels (across browser/OS).

My approach: add a scroll event-handler to the listbox to scroll 100 pixels.

I used onWheel and Element.scrollBy():

I am trying to edit cookie for all API calls using webRequest from a cross-browser (supporting chrome and Firefox) extension which I am creating.

Following is the code:

I have had this function for a long time. I made it myself. For like half the time it wouldn't work at all, but then after a while I managed to fix it. However, this is not the reason this is here.
