Mozilla launches global Internet compatibility tracker

Martin Brinkmann

There are many devices and web browsers that you can use to access web resources. Mozilla wants to push the Internet towards full compatibility with all of those devices and browsers, so that users do not run into any issues when they access services and web pages regardless of device or software they use.

That's the main idea behind Webcompat, a new bug tracking service that Mozilla created to improve compatibility on the Internet.

While it has been created by Mozilla, it is not associated with Firefox or other Mozilla products, and Mozilla is not providing resources at the time of writing to resolve reported bugs.

The idea is to make this a web project that Internet users can join to report bugs, or to reach out to websites and services to inform them about them.

As a webmaster, it may pay to visit the Webcompat website from time to time to make sure that your sites and services are not listed here, or if they are listed, to address the issues described in the bug report.

To report a bug you need to have a Github account. That is the only requirement though.

web bug report

A bug report always includes a web address and a short problem description in five words or less. You can additionally add the browser and version that you used while you ran into the problem, and replication steps before you hit the report bug button.

While you do not have to fill out the optional fields, it is likely that it will increase the chance of the bug being reported to the operators of the site or discussed in the bug report listing if you do.


Mozilla runs Bugzilla that is being used to track issues in products such as Firefox. This includes desktop and mobile web compatibility issues which are handled by the company's web compatibility team.

The Webcompat service on the other hand is vendor-agnostic. It is a broader approach that looks beyond Firefox to ultimately ensure that the web works for everyone regardless of web browser used.

The idea to move the project into the hands of the community is without doubt an interesting one and in my opinion the only logical option.

Mozilla does not have the resources to handle these bug reports on its own, and while the organization keeps an oversight on the project, it is the community that is reporting bugs and contacting website operators to get those issues resolved.

While it has been possible before, the Webcompat service standardizes the reporting and provides the option to discuss reported bugs.


These two links list the desktop and mobile compatibility issues that have been reported using the service. Note that they link to Bugzilla.

Closing Words

The project is at its beginning. This becomes obvious when you open the main website, as the tracking is currently hosted on a dev subdomain which provides you with an early preview of what is to come in the future.

Success or failure depends largely on how fast Mozilla will move the service to the main domain, and word of mouth. If enough users get involved early on, it is likely that it will take off and that it will receive a steady stream of bug submissions for years to come. (via Sören)

      Well it is a bit difficulty to distinguish between domains and files for instance.

    @Ashwin–Thankful you delighted my comment; who knows how many “gamers” would have disagreed!

    The comments section under this very article (3 comments) is identical to the comments section found under the following article:

    Not sure what the issue is, but have seen this issue under some other articles recently but did not report it back then.

    With the cloud, there is no such thing as unlimited storage or privacy. Stop relying on these tech scums. Purchase your own hardware and develop your own solutions.

      This is a certified reddit cringe moment. Hilarious how the article’s author tries to dress it up like it’s anything more than a png for doing the reddit corporation’s moderation work for free (or for bribes from companies and political groups)

    With Google Chrome, it’s only been 1,500 for some time now.

    Anyone who wants to force me in such a way into buying something that I can get elsewhere for free will certainly never see a single dime from my side. I don’t even know how stupid their marketing department is to impose these limits on users instead of offering a valuable product to the paying faction. But they don’t. Even if you pay, you get something that is also available for free elsewhere.

    The algorithm has also become less and less savvy in terms of e.g. English/German translations. It used to be that the bot could sort of sense what you were trying to say and put it into different colloquialisms, which was even fun because it was like, “I know what you’re trying to say here, how about…” Now it’s in parts too stupid to translate the simplest sentences correctly, and the suggestions it makes are at times as moronic as those made by Google Translations.

    If this is a deep-learning AI that learns from users’ translations and the phrases they choose most often – which, by the way, is a valuable, moneys worthwhile contribution of every free user to this project: They invest their time and texts, thereby providing the necessary data for the AI to do the thing as nicely as they brag about it in the first place – alas, the more unprofessional users discovered the translator, the worse the language of this deep-learning bot has become, the greater the aggregate of linguistically illiterate users has become, and the worse the language of this deep-learning bot has become, as it now learns the drivel of every Tom, Dick and Harry out there, which is why I now get their Mickey Mouse language as suggestions: the inane language of people who can barely spell the alphabet, it seems.

    And as a thank you for our time and effort in helping them and their AI learn, they’ve lowered the limit from what was once 5,000 to now 1,500…? A big “fuck off” from here for that! Not a brass farthing from me for this attitude and behaviour, not in a hundred years.
