A person should be able to use the Web with any devices and browsers.
Our attempt is to help both website developers and browser implementers to reach a point where users have no issues when browsing the Web because of their choices.
Cross Browsers. Any vendors

The Web Compatibility activity is composed of permanent Mozilla staff and volunteer contributors. We are part of the Developer Experiences Team.
- Our current projects.
The web compatibility team is composed of:

Tech Evangelism Triage
All are welcome to participate.
The current goal is to triage the backlog and make sure we haven't missed important bugs to be diagnosed, or to catch what has been fixed. Anything deemed not important will be made P5, and won't appear in query results.
- Thursdays, 8am Pacific, Vidyo Channel Compatibility
- Untriaged Tech Evangelism::Desktop and ::Mobile with no priority (minus P5s)
What is Web Compatibility
Web Compatibility issues are related to Web sites implementing techniques that create issues for a certain class of browsers and/or devices. A person will not be able to use a Web site according to his/her own choices.
These issues are cross-platforms, cross-products and related to the Web as a whole. There are circumstances when a company will choose to use a standardized techniques which is not available for an old browser, but that should be mitigated in making the Web site usable in any circumstances. So if a person is using the last version of Firefox or a vocal browser such as Jaws, or a proxy browser such as Opera Mini or UCWeb, the Web site should be able to work.
Mozilla has two areas for dealing with Web Compatibility issues. The goal is to make the Web usable by anyone and not only Firefox products, but we will focus the efforts on solving issues for Firefox users.
Web Compatibility issues can change over time, we keep an updated list of the most common issues.
Web Compatibility Taxonomy
Why sites are failing in Firefox? What can we do when this is happening?
- We can outreach the site. Long process and not always successful
- We may be able to shim it inside Firefox while attempting to do outreach.
- We can fix it in Firefox if really widespread on too may sites. It becomes (unfortunately) part of the Web reality.
- The Web site is sending a specific working version of the site. Often based on user agent sniffing both on the client side or/and the server side. Examples: Different tier version for different browsers (Google search, Baidu, etc.). These can be very difficult to solve. It's more business related than a technical issue.
- We can outreach to the site, if we can demonstrate that the other version is working well in Firefox.
- We can create a UA override in some circumstances. Drawback: we disappear from the statistics.
- The Web site is sending to a specific interactions of the site through features detections.
- We can outreach to the site.
- We can try to shim it.
- The Web site is using a standard technology not yet supported by Firefox. Example: SpeechRecognition. This creates a load of secondary issues such as adding future code detection legacies. The Webcompat issues of today are sometimes created by the lack of support of technologies of yesterdays.
- We need to fix it in Firefox.
- The Web site is using a non-standard technology not yet supported by Firefox. Example from the past: innerText, window.event, … These are hard to fix. When we fix it in Firefox, we create secondary compatibility issues, because sites were relying on it. Example: using window.event, to target the detection of keyCode.
- We can fix it in Firefox, but we need to deal with the consequences too.
- We can outreach if the problem is not widespread.

You can participate into making the Web a better place by handling these issues.
