## Supported browsers
Bootstrap supports the **latest, stable releases** of all major browsers and platforms. On Windows, **we only support Microsoft Edge**.
Alternative browsers which use the latest version of WebKit, Blink, or Gecko, whether directly or via the platform's web view API, are not explicitly supported. However, Bootstrap should (in most cases) display and function correctly in these browsers as well. More specific support information is provided below.
You can find our supported range of browsers and their versions [in our `.browserslistrc file`]({{< param repo >}}/blob/v{{< param current_version >}}/.browserslistrc):

Chrome >= 45
Firefox >= 38
Edge >= 12
iOS >= 9
Safari >= 9
Android >= 4.4
Opera >= 30
```
We use [Autoprefixer](https://github.com/postcss/autoprefixer) to handle intended browser support via CSS prefixes, which uses [Browserslist](https://github.com/browserslist/browserslist) to manage these browser versions. Consult their documentation for how to integrate these tools into your projects.
### Mobile devices
Generally speaking, Bootstrap supports the latest versions of each major platform's default browsers. Note that proxy browsers (such as Opera Mini, Opera Mobile's Turbo mode, UC Browser Mini, Amazon Silk) are not supported.

For Firefox, in addition to the latest normal stable release, we also support the latest [Extended Support Release (ESR)](https://www.mozilla.org/en-US/firefox/organizations/#faq) version of Firefox.
Unofficially, Bootstrap should look and behave well enough in Chromium and Chrome for Linux, Firefox for Linux, and Internet Explorer 9, though they are not officially supported.
For a list of some of the browser bugs that Bootstrap has to grapple with, see our [Wall of browser bugs](/docs/{{< param docs_version >}}/browser-bugs/).
## Internet Explorer
Internet Explorer 11 is not supported officially. However, if you build Bootstrap yourself, you can add the needed CSS prefixes and follow the instructions on the [JavaScript page](/docs/{{< param docs_version >}}/getting-started/javascript/#compatibility-with-ie-11). Please note that this might break at any time. **If you require Internet Explorer 10/11 support, use Bootstrap 4.**
## Modals and dropdowns on mobile
### Overflow and scrolling
Support for `overflow: hidden;` on the `` element is quite limited in iOS and Android. To that end, when you scroll past the top or bottom of a modal in either of those devices' browsers, the `` content will begin to scroll. See [Chrome bug #175502](https://bugs.chromium.org/p/chromium/issues/detail?id=175502) (fixed in Chrome v40) and [WebKit bug #153852](https://bugs.webkit.org/show_bug.cgi?id=153852).
### iOS text fields and scrolling
As of iOS 9.2, while a modal is open, if the initial touch of a scroll gesture is within the boundary of a textual `` or a `
