How many of you experience slowdowns when using ViewAbout 2.0? I’ve noticed that when there is high I/O activity, viewabout.js sometimes throws up a slow JavaScript dialog on startup. Recently, I’ve also noticed that the performance of Firefox 4 Beta / RC seems to slowdown significantly over time as one uses large numbers of tabs (e.g. more than 80) and one would have to restart Firefox. Or disable ViewAbout and the issue seems to go away.

I’ve also experienced lags when opening new windows through JavaScript links with the extension. Another ponder: How easy would it be to transit ViewAbout to being restart-less? There doesn’t seem to be a menu API in the latest Add-on SDK at the time of writing.

The relevant viewabout.js file is located here. Some of that code was submitted by a contributor some time back, and I’m not entirely sure what is causing the issue. Any ideas?

Edit: I’ve released the ViewAbout 2.0.1 hotfix to AMO to try and combat this issue. Thanks especially go out to harry for suggesting an alternative way of detecting about: URLs in the application.

Changelog for previous release (Thunderbird 3.1.8) | Changelogs for other Thunderbird releases

Released on 04 Mar 11, and this changelog was last updated on 08 Mar 11.

Thunderbird 3.1.9 has been released. Release notes are available. This post lists the improvements in Thunderbird 3.1.9 over Thunderbird 3.1.8. This list encompasses almost every single known fix that went into this release, but excludes platform-wide fixes. Do check out the known issues as well.

Impact key for security issues (fixed in this version) that are listed on the Mozilla Foundation Security Advisories webpage:

• Critical: Vulnerability can be used to run attacker code and install software, requiring no user interaction beyond normal browsing.
• High: Vulnerability can be used to gather sensitive data from sites in other windows or inject data or code into those sites, requiring no more than normal browsing actions.
• Moderate: Vulnerabilities that would otherwise be High or Critical except they only work in uncommon non-default configurations or require the user to perform complicated and/or unlikely steps.
• Low: Minor security vulnerabilities such as Denial of Service attacks, minor data leaks, or spoofs. (Undetectable spoofs of SSL indicia would have “High” impact because those are generally used to steal sensitive data intended for other sites.)

Changelog for previous release (Thunderbird 3.1.7) | Changelogs for other Thunderbird releases

Released on 01 Mar 11, and this changelog was last updated on 02 Mar 11.

Thunderbird 3.1.8 has been released. Release notes are available. This post lists the improvements in Thunderbird 3.1.8 over Thunderbird 3.1.7. This list encompasses almost every single known fix that went into this release, but excludes platform-wide fixes. Do check out the known issues as well.

Impact key for security issues (fixed in this version) that are listed on the Mozilla Foundation Security Advisories webpage:

• Critical: Vulnerability can be used to run attacker code and install software, requiring no user interaction beyond normal browsing.
• High: Vulnerability can be used to gather sensitive data from sites in other windows or inject data or code into those sites, requiring no more than normal browsing actions.
• Moderate: Vulnerabilities that would otherwise be High or Critical except they only work in uncommon non-default configurations or require the user to perform complicated and/or unlikely steps.
• Low: Minor security vulnerabilities such as Denial of Service attacks, minor data leaks, or spoofs. (Undetectable spoofs of SSL indicia would have “High” impact because those are generally used to steal sensitive data intended for other sites.)
