Millions of people rely on the Mozilla Firefox Web browser, but now some of them might not be able to access the content they want, thanks to the latest update.
A bug affecting the way the browser handles the Canvas HTML element was introduced in this week’s 22.214.171.124 release.
Canvas is an advanced HTML
element natively included in Firefox that is used for on-the-fly rendering
of bitmap images.
The flaw, called “canvas.drawImage is not working” by Bugzilla, was first reported within hours of the 126.96.36.199 release on Nov. 26. An initial fix was checked into
Mozilla’s development system a day later and has been undergoing testing
“We are using drawImage alot in our web shop and now in Firefox 188.8.131.52
everything is broken,” Bugzilla commenter Klaus Reimer wrote. “Customers are
complaining because their Firefox automatically updated to 184.108.40.206 and now
they can no longer order photo prints in our shop. I think this is a very
serious problem and I hope it will be fixed immediately in a 220.127.116.11
Mozilla users have been asking in Bugzilla how soon a generally
available fix will be made available in the form of a 18.104.22.168
release. Mozilla developer Nick Thomas said the 22.214.171.124 release
is tentatively scheduled for today, adding that if it plays out that way, it will be the fastest turnaround between Firefox releases
The pace of Mozilla updates has hardly been slow lately. The 126.96.36.199
release followed the Firefox 188.8.131.52 update by less than a month. The 184.108.40.206 update was only two
weeks behind Firefox 220.127.116.11.
All told, the frequent Firefox updates and this latest broken Canvas issue
in 18.104.22.168 may well be frustrating for those who use Firefox. The broken
Canvas tag bug has also raised the issue of how effectively Mozilla tests
its releases before making them generally available.
“I am really surprised the canvas part was not even tested before releasing
22.214.171.124,” Bugzilla commenter Chris Lui wrote. “I still support Firefox,
although I consider this incident really dampen it a lot.”
Another commenter noted that he has supported Firefox and tried to make full
use of its features in development. The Canvas bug issue, according to
“Jonathan” has put egg on his face.
“For a couple days we have had an unbearable number of support calls,”
Jonathan wrote. “I would hope this reinforces the need for someone to put in
some serious effort on developing a solid and extensive suite of regression
tests. This should have NEVER gotten into a public release.”
In its defense, Mozilla developers in the same Bugzilla thread noted that
they make nightly builds available to all who want to test. Mozilla also
produces release candidates ahead of generally available security updates, so
those who don’t have the time to test nightly can test as needed against the candidates.
Thomas commented that the release candidates are publicly announced on the
mozilla.announce-prerelease newsgroup on news.mozilla.org.
The 126.96.36.199 release candidate update is available now for those who want to make sure it works with their sites.
